Background

Liquid treatment apparatus typically use natural gas, electricity or other energy sources to regulate the temperature of liquid, and may be used to treat liquid for administration to bathrooms, kitchens, toilets and the like, and to provide the user with a suitable temperature. The fluid circulation control system may distribute the treated fluid to the various outlets (e.g., faucets) via a piping system.

In the related art, the liquid in the pipe is generally treated in the following two ways. Firstly, all pipelines of the whole liquid circulation control system are treated at regular time in a manner of timing cruising; and secondly, heating or cooling all the pipelines of the whole liquid circulation control system when the temperature in the pipelines is lower than or higher than the preset temperature in a constant temperature cruising mode.

The liquid circulation control system on the market at present is mainly realized by the following modes: firstly, a water return pipe is added during decoration or a water return valve is added at the cold and hot water connection part of a household pipeline, so that the liquid in the pipeline can be circulated back to a liquid circulation control system for heating or refrigerating treatment. Secondly, a circulating pump or an external circulating pump is added in the liquid circulation control system to provide power so that the liquid to be treated can be circularly heated or cooled, so that the liquid treatment of all the pipelines is realized, but the pipeline residual water of the whole house and even the water comprising the cold water pipeline need to be treated all the time when the liquid is circulated each time, so that the energy consumption is high, and the problem of high energy consumption is caused without targeted heating.

Based on the above, the embodiment of the application provides a liquid circulation control method, a liquid circulation control system, electronic equipment and a storage medium, which can reduce the energy consumption of the liquid circulation control system.

The liquid circulation control method, the liquid circulation control system, the electronic device and the storage medium provided by the embodiment of the application are specifically described through the following embodiments, and the liquid circulation control system in the embodiment of the application is described first.

Referring to fig. 1, in some embodiments, the liquid pipelines in the building are arranged as shown in fig. 1, and the end of each liquid pipeline is connected to a plurality of liquid circulation control systems, and is heated or cooled by a liquid treatment device 101. It is to be understood that the liquid processing apparatus 101 may be configured to perform a heating function of a liquid and a cooling function of a liquid separately, or may be configured to perform both a heating function and a cooling function of a liquid. Illustratively, the liquid treatment apparatus 101 may be a water heater, a refrigerator, a cooling tower, or the like, to which the present application is not particularly limited.

Further, referring to fig. 2, fig. 2 shows a schematic diagram of a liquid circulation control system, which includes at least one water outlet 102, each connected to a liquid treatment apparatus 101 through a liquid pipeline. Specifically, the water outlet end may be a part for draining water of a water outlet shower, a faucet, or the like. In some embodiments, the liquid lines may include a liquid main line connected to the liquid treatment apparatus 101 and a plurality of liquid branch lines for connecting the liquid main line with corresponding water outlets.

In some embodiments, the hydronic control system further comprises a processor 103, and the processor 103 may be a neural hub and command center of the hydronic control system. The processor can generate an operation control signal according to the instruction operation code and the time sequence signal, complete the control of instruction fetching and instruction execution, and execute the liquid circulation control method according to the instruction.

In some embodiments, a water pump 104 is disposed on each liquid pipeline, so that when each liquid circulation system needs to heat or refrigerate liquid, the liquid in the liquid branch pipeline where the water outlet end is located can be circulated through the on-off state of the water pump, and the liquid in all the pipelines does not need to be circulated. Illustratively, the liquid circulation control system is further provided with a temperature sensor 105 and a flow meter 106, the temperature sensor 105 is used for acquiring a first temperature, an initial temperature, a second temperature and/or the like, the temperature sensor 105 is capable of acquiring temperatures on all liquid pipelines, and the flow meter is used for acquiring flow values of the liquid pipelines. The liquid circulation control system is further provided with a water mixing valve 107 which can be opened to mix the treated liquid with tap water of a tap water pipe after the liquid treatment device 101 heats or cools the liquid, and then the liquid is discharged through the water outlet end 102 after the liquid is mixed. When the water outlet end 102 is in an open state, the water pump 104 can convey the liquid in the liquid pipeline to the liquid treatment equipment 101 for heating, and when the water outlet end 102 is in a water outlet state, the water pump 104 is closed, and the water mixing valve 107 is opened.

It will be appreciated that the fluid circulation control system is also provided with a memory 108 for connection to an external memory card, such as an SD card, for enabling storage of data of the fluid circulation control system. The memory 108 may be in communication with the processor 103 to implement data storage functions.

Further, the liquid circulation control system further includes a wireless module 1010, configured to implement communication connection between the water outlets 102, and may further include a hot and cold water switch 1011, configured to detect a state of the water outlet 102.

In the embodiments of the present application, when related processing is required according to user information, user behavior data, user history data, user location information, and other data related to user identity or characteristics, permission or consent of the user is obtained first. Moreover, the collection, use, processing, etc. of such data would comply with relevant laws and regulations. In addition, when the embodiment of the application needs to acquire the sensitive personal information of the user, the independent permission or independent consent of the user is acquired through popup or jump to a confirmation page and the like, and after the independent permission or independent consent of the user is definitely acquired, the necessary relevant data of the user for enabling the embodiment of the application to normally operate is acquired.

Fig. 3 is an alternative flow chart of a method for controlling liquid circulation according to an embodiment of the present application, and the method in fig. 2 may include, but is not limited to, steps S101 to S104.

Step S101, when the control state of the water outlet end is an on state, acquiring a preset temperature corresponding to the water outlet end, and detecting a first temperature of liquid in a liquid pipeline corresponding to the water outlet end.

In some embodiments, the water outlet may be a faucet, a shower, a sprayer, or the like, connected by a liquid line. The control state of the water outlet end is multiple, such as an opening state, a closing state, a circulating state and the like, the processor can detect the flowing condition of liquid through the flowmeter and judge the flowing condition of the water outlet end, or the liquid level sensor is arranged to determine the state of the water outlet end, and further, the state of the water outlet end can be judged by monitoring the state of a cold water switch and a hot water switch at the water outlet end.

It will be appreciated that the preset temperature is a temperature value that is stored in advance in the liquid circulation control system and is required to be reached by the liquid treatment apparatus after the liquid treatment is completed, for example, if the liquid treatment apparatus is a water heater, the preset temperature is set to be 85 degrees, the liquid needs to be heated to be 85 degrees, and if the liquid treatment apparatus is a water chiller, the preset temperature is set to be 2 degrees, the liquid needs to be cooled to be 2 degrees. The preset temperature can be set when the liquid treatment equipment leaves the factory or set by a user, and can be adjusted according to actual conditions.

For example, the first temperature corresponding to the water end can be detected by the temperature sensor, and the processor can read the signal of the temperature sensor. It will be appreciated that the temperature sensor is provided with a digital interface and that temperature data can be transmitted directly to the control system.

Step S102, the pipeline capacity of the liquid pipeline is obtained.

In some embodiments, the pipeline capacity of the liquid pipeline is fixed, and can be obtained by installing a flowmeter in the liquid circulation control system, specifically, each water outlet end corresponds to one flowmeter, the flowmeter is installed on one side of the liquid pipeline with each water outlet end, and the flowmeter can also be directly installed on the water outlet end, and the installation position is used for enabling the liquid flowing through the flowmeter to be stable and free from liquid fluctuation. Further, the flowmeter will record the flow rate of the liquid through the liquid pipeline, and multiply the time for the liquid to circulate from the water outlet end to the liquid treatment equipment, so as to obtain the pipeline capacity of the liquid pipeline. In some embodiments, the line capacity may be calculated directly from the length of the liquid line and the diameter of the liquid line, as embodiments of the application are not particularly limited.

Step S103, obtaining a temperature difference value between a preset temperature and a first temperature, and calculating the pipeline compensation quantity of the liquid pipeline based on the ratio of the temperature difference value and the compensation coefficient of the water outlet end.

In some embodiments, the compensation factor is a fixed relationship value that reflects the temperature of the liquid in the liquid line and the compensation amount of the line, and may be measured through experimental data or may be calculated through line data. In some embodiments, the calculation formula for the line compensation amount is as follows:

L_{Pipeline compensation amount}＝(T_{Preset temperature}-T_{first temperature})/K_{compensation coefficient}；

Wherein, L _{Pipeline compensation amount} represents the compensation amount of the pipeline, T _{Preset temperature} represents the preset temperature, T _{first temperature} represents the first temperature, and K _{compensation coefficient} represents the compensation coefficient.

In some embodiments, the line offset is the amount of hot water or cold water that needs to be offset to raise the hot water in the liquid line from the first temperature to the preset temperature when the liquid in the liquid line is full. For example, when the temperature is set to 90 degrees and the temperature in the liquid pipeline is 50 degrees, the pipeline compensation amount is the hot water amount required to be compensated when the hot water in the liquid pipeline is heated from 50 degrees to 90 degrees. Or the temperature is set to be 2 ℃, and at the moment, the temperature in the liquid pipeline is 39 ℃, and then the pipeline compensation amount is the hot water amount required to be compensated when the hot water in the liquid pipeline is cooled from 39 ℃ to 2 ℃.

Step S104, calculating the heating cycle time of the liquid in the liquid pipeline from the first temperature to the preset temperature based on the flow value, the pipeline capacity and the pipeline compensation amount of the liquid pipeline, determining the water outlet time of the water outlet end according to the heating cycle time, and controlling the water outlet end to be in a water outlet state at the water outlet time.

In some embodiments, the calculation formula for the warm-up cycle time is as follows:

Where L _{pipeline capacity} denotes a line capacity, L _{Pipeline compensation amount} denotes a line compensation amount, L _{Flow value} denotes a flow rate value, and t _{cycle time of temperature rise} denotes a temperature rise cycle time.

It will be appreciated that the amount of liquid passing through the liquid line per unit time during the heating or cooling process can be known from the flow value, and the total amount of liquid in the liquid line can be obtained from the line capacity. The liquid change value of the liquid pipeline in the whole heating or cooling process can be known by adding the pipeline capacity and the pipeline compensation quantity, and then the heating process of all liquid in the liquid pipeline can be calculated by combining the flow value.

In some embodiments, the water outlet time of the water outlet end can be determined through the temperature rising circulation time, and the control state of the water outlet end is ensured to be the water outlet state during the water outlet time, so that the temperature rising, the temperature reducing or the water outlet control of the liquid can be optimized according to the actual liquid pipeline condition, and more efficient and accurate liquid temperature control is realized.

It can be understood that in the embodiment of the application, each water outlet corresponds to one water pump and one water mixing valve, so that when heated or cooled liquid is not required to be obtained at one water outlet, all the pipelines of the whole system are heated or cooled, and the energy consumption of the system is greatly reduced. In some embodiments, in a scene that a user needs to use hot water, when the user turns on the hot and cold water switch through normal use, and when a first temperature (for example, 65 degrees) acquired by the temperature sensor is above a set preset temperature (for example, 50 degrees), the water mixing valve is normally controlled to be opened, hot water is discharged through the water outlet end, and a water pump is not required to be turned on for circulation; when the first temperature (such as 33 degrees) acquired by the temperature sensor is smaller than the preset temperature (such as 50 degrees) set by a user, the water mixing valve corresponding to the water outlet end is closed, the water pump corresponding to the water outlet end is opened for circulating heating, meanwhile, the first temperature of the current liquid pipeline and the pipeline capacity of the liquid pipeline are recorded, when the temperature of the liquid pipeline reaches the preset temperature (such as 50 degrees) set by the user, the water pump corresponding to the water outlet end is closed for circulating, and the water mixing valve is opened for water outlet.

In a scene that a user needs to use cold water, when the user turns on a cold water switch through normal use, and when a first temperature (for example, 5 ℃ C.) acquired by a temperature sensor is below a set preset temperature (for example, 10 ℃ C.), the water mixing valve is normally controlled to be opened, and the cold water is discharged through a water outlet end without opening a water pump for circulation; when the first temperature (20 degrees for example) acquired by the temperature sensor is greater than the preset temperature (10 degrees for example) set by a user, closing the water mixing valve corresponding to the water outlet end, opening the water pump corresponding to the water outlet end for circulating refrigeration, simultaneously recording the first temperature of the current liquid pipeline and the pipeline capacity of the liquid pipeline, when the temperature of the liquid pipeline reaches the preset temperature (10 degrees for example) set by the user, closing the water pump circulation corresponding to the water outlet end, and opening the water mixing valve for water outlet.

It can be understood that the heating cycle time is the time when the water pump is turned on, but the water mixing valve is not turned on to discharge water, and the liquid needs to be heated or cooled; the water outlet time is the time of opening the water mixing valve to outlet water after the liquid is heated or refrigerated to reach the preset temperature. For example, if the first temperature is 30 degrees and the preset temperature is 60 degrees, the user needs water because the first temperature is less than the preset temperature, and the liquid needs to be heated. The time for setting the water outlet end to be in an open state is 12:20, if 40 minutes are required to heat from 30 degrees to 60 degrees, then 30 minutes is the warm-up cycle time, and 12: 60 degrees at 50, then 12: and 50 is the initial time, and at this time, the water outlet end is used for discharging water, and the control state of the water outlet end is the water outlet state.

Referring to fig. 4, in some embodiments, before calculating the line compensation amount of the liquid line based on the ratio of the temperature difference and the compensation coefficient of the water outlet, the method may further include steps S201 to S204:

Step S201, a flow value of the liquid pipeline is obtained, and a target temperature of the water outlet end and an initial temperature of liquid in the liquid pipeline are set.

In some embodiments, the target temperature of the water outlet end of the flow value reading device may be a set temperature of the liquid treatment apparatus when leaving the factory, or may be a temperature set by a user, and it is understood that the set temperature may be different due to different seasons or air temperatures. It will be appreciated that the initial temperature of the liquid in the liquid line may be measured by temperature sensors mounted at the water outlet ends, one for each water outlet end.

Step S202, a first time when the liquid in the liquid pipeline is heated from the initial temperature to the target temperature is obtained.

In some embodiments, the initial temperature may be obtained by a temperature sensor, where the initial temperature is the liquid temperature of the liquid pipeline when not heated, and for example, if the temperature of the liquid pipeline is 25 degrees, the target temperature is 70 degrees, after the user turns on the hot and cold water switch, since the initial temperature is less than the target temperature, the water pump needs to be turned on to circulate, and at this time, the 25 degrees is taken as the initial temperature. It will be appreciated that the first time to warm up from the initial temperature to the target temperature may be obtained by a temperature sensor which may measure the temperature of the liquid line and transmit the temperature data to a processor which may record the temperature data measured by the temperature sensor and may monitor and record the warm up process of the liquid in real time and obtain the first time for the liquid to warm up from the initial temperature to the target temperature. It is understood that the temperature raising process is an increase in temperature, or a decrease in temperature. Specifically, when the temperature of the liquid pipeline is changed from 10 degrees to 50 degrees, the temperature is raised by 40 degrees; when the temperature of the liquid pipeline is changed from 40 degrees to 2 degrees, the temperature is raised to-38 degrees.

It will be appreciated that the temperature sensor may employ a thermistor, thermocouple, etc., depending on such factors as the application scenario, the nature of the liquid, and the accuracy requirements of the measurement.

Step S203, calculating the target pipeline compensation quantity of the liquid pipeline according to the flow value and the first time.

In some embodiments, the target line compensation amount of the liquid line can be obtained by multiplying the flow value by the first time, and the specific formula is as follows:

L_{Target line compensation amount}＝l_{Flow value}*t_{First time of}；

Where L _{Flow value} denotes a flow value, t _{First time of} denotes a first time, and L _{Target line compensation amount} denotes a target line compensation amount.

It will be appreciated that the flow value is a measure of the speed and amount of liquid flowing in the liquid line, the first time represents the time required for the liquid to rise from the initial temperature to the target temperature, and the first time has a direct relationship with the amount of heat or cold received by the liquid, so that the target line compensation amount corresponding to the total heat or total cold received by the liquid in the liquid line can be calculated more accurately by multiplying the flow value by the first time, thereby helping to achieve more accurate calculation.

Step S204, calculating a compensation coefficient according to the target pipeline compensation quantity, the initial temperature and the target temperature.

Illustratively, the compensation coefficient is calculated as follows:

Wherein L _{Target line compensation amount} represents a target line compensation amount, T _{Initial temperature} represents an initial temperature, T _{Target temperature} represents a target temperature, and K _{compensation coefficient} represents a compensation coefficient.

In some embodiments, the compensation coefficient is a fixed value, and may be set according to practical situations. The compensation coefficient represents the relation between the additional heat or cold required in the heating or cooling process of the liquid and the flow value and time.

Referring to fig. 5, in some embodiments, step S204 may include steps S301 to S302:

step S301, a compensated temperature difference between the target temperature and the initial temperature is calculated.

In step S302, the ratio of the compensated temperature difference to the target line compensation amount is used as a compensation coefficient.

It will be appreciated that calculating the compensated temperature difference between the target temperature and the initial temperature may determine the amount of heat or cold in the liquid line that the liquid treatment apparatus needs to compensate for. Specifically, the calculation formula for compensating the temperature difference is as follows:

T_{Compensating for temperature differences}＝T_{Target temperature}-T_{Initial temperature}；

Where T _{Initial temperature} denotes an initial temperature, T _{Target temperature} denotes a target temperature, and T _{Compensating for temperature differences} denotes a compensation temperature difference.

In some embodiments, the compensation coefficient is calculated as follows:

Wherein L _{Target line compensation amount} represents a target line compensation amount, T _{Compensating for temperature differences} represents a compensation temperature difference, and K _{compensation coefficient} represents a compensation coefficient.

It is understood that the compensation coefficient may be a constant value. In some embodiments, the compensation coefficient may be adjusted according to a specific scenario, for example, for different liquid pipelines with different diameters of home users, or different flow values of the liquid pipelines may correspond to different compensation coefficients, or for the case of compensating for temperature difference changes in different seasons, the compensation coefficient may be calculated by redetermining the compensation temperature difference, which is not limited in particular in the embodiment of the present application.

Referring to fig. 6, in some embodiments, step S102 may include steps S401 to S402:

Step S401, obtaining a second time when the liquid in the liquid pipeline changes from the initial temperature to a second temperature; the difference between the second temperature and the initial temperature is a preset temperature threshold.

Step S402, calculating to obtain the pipeline capacity according to the second time and the flow value.

It will be appreciated that the predetermined temperature threshold is a very small value for determining whether a change in temperature in the fluid line has occurred. For example, the preset temperature threshold may be set to 0.0001 degrees, that is, the liquid in the liquid line changes by 0.0001 degrees based on the initial temperature, which indicates that the liquid in the liquid line changes from the initial temperature to the second temperature. Illustratively, in a scenario where the liquid is heated, the initial temperature is 30 degrees, the preset temperature threshold is 0.0001 degrees, and when the temperature in the liquid line changes to 30.0001 degrees, it indicates that the second temperature is reached.

It will be appreciated that when the temperature of the liquid line changes after the water pump is turned on, i.e. the water temperature of the liquid line begins to rise or begins to fall, the cycle time at that time may be recorded as the second time. It will be appreciated that when the temperature of the liquid line changes, it is indicated that the liquid treatment apparatus has now been circulated through the water outlet line, i.e. the entire line volume has been circulated, and the temperature will only begin to change. At this time, the line capacity can be calculated by the following formula:

L_{pipeline capacity}＝l_{Flow value}*t_{Second time of}；

Where t _{Second time of} denotes a second time, L _{Flow value} denotes a flow value, and L _{pipeline capacity} denotes a line capacity.

Referring to fig. 7, in some embodiments, calculating a temperature rise cycle time for raising the temperature of the liquid in the liquid pipeline from the first temperature to the preset temperature based on the flow value, the pipeline capacity and the pipeline compensation amount of the liquid pipeline may include steps S501 to S502:

step S501, obtaining the total capacity of pipeline temperature rise according to the sum of the pipeline capacity and the pipeline compensation quantity.

Step S502, heating cycle time is obtained based on the ratio of the total capacity of the pipeline heating and the flow value.

In some embodiments, the total capacity of the circuit warming is calculated as follows:

L_{Total capacity of pipeline temp. raising}＝L_{pipeline capacity}+L_{Pipeline compensation amount}；

Where L _{Total capacity of pipeline temp. raising} represents the total line temperature increase capacity, L _{pipeline capacity} represents the line capacity, and L _{Pipeline compensation amount} represents the line compensation amount.

The calculation formula of the temperature rise cycle time is as follows:

Where L _{Total capacity of pipeline temp. raising} represents the total capacity of the line temperature rise, L _{Flow value} represents the flow value, and t _{cycle time of temperature rise} represents the temperature rise cycle time.

It is understood that the pipeline capacity refers to the total volume occupied by the liquid in the liquid pipeline, the pipeline compensation amount refers to the hot water amount or cold water amount required to be compensated by the liquid pipeline when the first temperature is raised to the preset temperature, and the pipeline heating total capacity can be calculated by the sum of the pipeline capacity and the pipeline compensation amount because the liquid in the liquid pipeline needs to be heated when the liquid is raised to the preset temperature.

Further, since the flow value represents the volume of liquid passing through the liquid pipeline in unit time, the heating cycle time can be accurately calculated by the ratio of the total heating capacity of the pipeline to the flow value.

In some embodiments, the temperature rise time may be displayed to the user through a display, and in particular, a countdown manner may be adopted, for example, 10 minutes is required for reaching the preset temperature; the corresponding cycle time can also be displayed directly, for example twenty minutes for heating, or at 12:36 heating is completed.

Furthermore, the alarm can be set to remind the user that the liquid is heated to the preset temperature or the temperature is reduced to the preset temperature, so that the user can use water in time, the water temperature in the liquid pipeline is prevented from changing again, the energy is consumed again for heating, and the energy is saved.

Referring to fig. 8, in some embodiments, there are a plurality of water outlets; calculating a temperature-increasing cycle time for increasing the temperature of the liquid in the liquid line from the first temperature to the preset temperature based on the flow value of the liquid line, the line capacity, and the line compensation amount may include steps S601 to S603:

step S601, obtaining control states of other water outlets; the control states include an on state and a water out state.

It can be understood that there are a plurality of water outlets, so that a situation that a plurality of water outlets are opened simultaneously or a plurality of water outlets are opened sequentially may occur, at this time, the heating cycle time of each water outlet can be accurately calculated by the target capacity and the flow value, and the display in each water outlet displays the heating cycle time.

Specifically, the control states of other water outlets can be obtained for the water outlet end which needs to calculate the heating cycle time at present, wherein the control states comprise an opening state and a water outlet state. It can be understood that the open state indicates that the corresponding water outlet end has opened the water pump, but since the temperature in the liquid pipeline does not reach the preset temperature, the circulating heating is still needed, and the water outlet end is in the open state but does not output water. The water outlet state indicates that the corresponding water outlet end is closed, the temperature in the liquid pipeline reaches the preset temperature, the continuous cyclic heating is not needed, the water mixing valve is in an open state, and the water outlet end is in a water outlet state.

Step S602, generating a control pipeline capacity parameter according to the control state, and calculating the target capacity of the water end based on the control pipeline capacity parameter, the pipeline capacity and the pipeline compensation amount.

In some embodiments, the control pipeline capacity parameter may be a circulated water amount, a control pipeline capacity, a control pipeline compensation amount and the like, the pipeline capacity parameter is adjusted through the control state, so that the system can determine the flux of liquid, and therefore more accurate calculation of the heating cycle time is achieved.

Step S603, calculating the temperature rise cycle time based on the target capacity and the flow rate value.

In some embodiments, the temperature rising cycle time can be calculated by dividing the target capacity by the flow value, so that the temperature rising cycle time under the preset temperature and flow value can be calculated, and the temperature rising cycle time of the water outlet end under different working conditions can be accurately calculated.

Referring to FIG. 9, in some embodiments, the control conduit capacity parameter includes the amount of circulated water; step S602 may include steps S701 to S703:

In step S701, the other water outlet in the open state is taken as the first water outlet, and the open duration of the first water outlet is obtained.

In some embodiments, for the water outlet end that needs to calculate the heating cycle time at present, other water outlet ends in the open state are obtained as the first water outlet end, and the other water outlet ends are in the open state, which indicates that the other water outlet ends open the water pump, but are heating or cooling, and the liquid in the liquid pipeline does not reach the preset temperature, so that water is not discharged. At this time, the opening duration of the first water outlet end may be obtained, specifically, by installing a sensor or a clock on each of the hot and cold water switches, and transmitting the collected data to the processor.

Step S702, calculating the circulated water amount according to the opening duration and the flow value of the first water outlet end.

In some embodiments, the formula for calculating the amount of circulated water is as follows:

L_{Water quantity circulated}＝l_{Flow value}*t_{duration of on-time}；

Where t _{duration of on-time} denotes the on-duration, L _{Flow value} denotes the flow value, and L _{Water quantity circulated} denotes the circulated water quantity.

It will be appreciated that the on duration may be indicative of the length of time that the liquid flows in the liquid line after the liquid has been heated or cooled by the pump, and the flow value is indicative of the amount of water flowing through the outlet per unit time. By multiplying the opening duration by the flow value of the first outlet, the amount of circulated water, such as the amount of circulated water of a circulating water cooling system or a circulating water heating system, can be calculated to more accurately predict and control the amount of circulated water.

And step 703, calculating the sum of the pipeline capacity and the pipeline compensation quantity, and sequentially subtracting the circulated water quantity to obtain the target capacity.

In some embodiments, since the other water outlet is not discharging water and has not reached the preset temperature, the circulated water amount needs to be added to the target volume, that is, the volume of water that needs to be continuously heated, so that the liquid in the liquid pipeline can reach the preset temperature. The sum of the pipe capacity and the pipe compensation amount can enable the liquid of the liquid pipe to reach the preset temperature, so that the sum of the pipe capacity and the pipe compensation amount of each water outlet end in an open state can be subtracted in sequence, and the circulated water amount can be subtracted to obtain the target capacity. The formula for specifically calculating the target capacity is as follows:

L_{Target capacity}＝L_{pipeline capacity}+L_{Pipeline compensation amount}-L_{Water quantity circulated}；

Where L _{pipeline capacity} represents the line capacity, L _{Pipeline compensation amount} represents the sum of the line compensation amounts, L _{Water quantity circulated} represents the circulated water amount, and L _{Target capacity} represents the target capacity.

Referring to FIG. 10, in some embodiments, the control pipe capacity parameters include control pipe capacity and control pipe offset; step S602 may include steps S801 to S804:

In step S801, the other water outlet ends in the water outlet state are used as the second water outlet end.

In some embodiments, the other water outlet ends do not need to calculate the warming cycle time relative to the other water outlet ends that are currently needed to calculate the warming cycle time. When other water outlets are in the water outlet state, the fact that the corresponding other water outlets are closed is indicated, the temperature in the liquid pipeline reaches the preset temperature, and the continuous cyclic heating is not needed, at the moment, the water mixing valve is in the open state, the other water outlets are in the water outlet state, and the other water outlets in the water outlet state are taken as second water outlets.

Step S802, obtaining a control pipeline capacity according to the pipeline capacity of the second water outlet end, and obtaining a control pipeline compensation amount according to the pipeline compensation amount of the second water outlet end.

In some embodiments, for each second water outlet in the water outlet state, the pipe capacity of the second water outlet may be used as the control pipe capacity, and the pipe compensation amount according to the second water outlet may be used as the control pipe compensation amount, so as to facilitate the subsequent calculation of the target capacity.

Step S803, subtracting the control pipe capacity from the pipe capacity to obtain a first parameter, and subtracting the control pipe compensation from the pipe compensation to obtain a second parameter.

In some embodiments, for the water outlet end that needs to calculate the heating cycle time, since the other pipes have already circulated part of the control pipe capacity and the control pipe compensation amount, before reaching the preset temperature and discharging water, the water outlet end that needs to calculate the heating cycle time does not have to recirculate the part that has already circulated the other water outlet end, that is, does not have to recirculate the control pipe capacity and the control pipe compensation amount, and can directly subtract the control pipe capacity and the control pipe compensation amount. Specifically, subtracting the control line capacity from the line capacity may yield a first parameter, and subtracting the line compensation amount from the control line compensation amount may yield a second parameter.

First parameter=l _{pipeline capacity}-L_{Controlling pipeline capacity};

second parameter=l _{Pipeline compensation amount}-L_{controlling the compensation amount of the pipeline};

Where L _{pipeline capacity} represents the line capacity, L _{Pipeline compensation amount} represents the sum of the line compensation amounts, L _{Controlling pipeline capacity} represents the control line capacity, and L _{controlling the compensation amount of the pipeline} represents the control line compensation amount.

Step S804, obtaining the target capacity according to the sum of the first parameter and the second parameter.

In some embodiments, the target capacity is obtained according to the sum of the first parameter and the second parameter, that is, the target capacity that the water outlet end needing to calculate the heating cycle time needs to circulate finally can be obtained.

Referring to fig. 11, in some embodiments, step S603 may include steps S901 to S902:

Step S901, calculating candidate circulation time according to the target capacity and the flow value;

In step S902, the minimum value of the candidate cycle time is selected as the temperature rising cycle time.

In some embodiments, in the case that the other water outlet ends have already been discharged, the current temperature rising cycle time of the water outlet end can be calculated. Specifically, if the heating cycle time of the water outlet end which is just opened needs to be calculated, the water outlet end which is just opened can be set as a target water outlet end, the candidate cycle time of the target water outlet end relative to each water outlet end which is in an opened state is calculated, and the minimum value of the candidate cycle time is selected as the heating cycle time.

It can be understood that if the heating cycle time of the water outlet end 1 needs to be calculated, the water outlet end in the water outlet state has the water outlet end 2, the water outlet end 3 and the water outlet end 4, at this time, the target capacity 2 of the water outlet end 1 is calculated respectively, and the candidate cycle time 2 is calculated through the target capacity 2; calculating a target capacity 3 of the water outlet end 1 relative to the water outlet end 3, and calculating a candidate circulation time 3 through the target capacity 3; the target capacity 4 of the water outlet end 1 is calculated, the candidate circulation time 4 is calculated through the target capacity 4, the candidate circulation time 2, the candidate circulation time 3 and the candidate circulation time 4 are compared, the minimum value of the candidate circulation time is selected as the heating circulation time, namely, the candidate circulation time which reaches the preset temperature at the highest speed is selected as the heating circulation time, so that the situation that which water outlet terminal is close to or far from the liquid treatment equipment is not considered, the method is suitable for the arrangement and combination of various water outlet sequences, and the accuracy of the calculation of the heating circulation time is improved. It will be appreciated that the candidate cycle time may be calculated by dividing the target capacity by the flow value, and the specific calculation method is as described above, and will not be described here.

Referring to fig. 12, in some embodiments, step S602 may further include steps S1001 to S1003:

step S1001, if at least one first water outlet end and at least one second water outlet end exist, calculating the sum of the pipeline capacity and the pipeline compensation quantity, and sequentially subtracting the circulated water quantity to obtain a first target capacity;

step S1002, subtracting the control pipeline capacity and the control pipeline compensation amount from the first target capacity in sequence to obtain the target capacity.

In some embodiments, the first water outlet is an open water outlet, and the second water outlet is an open water outlet, where the open water outlet is open but the temperature of the liquid pipe does not reach the preset temperature, and the liquid pipe is heating or cooling. It is understood that the first water outlet and the second water outlet may be plural.

In some embodiments, for the water outlet end where the heating cycle time needs to be calculated, the sum of the pipeline capacity and the pipeline compensation amount can be calculated, then the circulating water amount in the first water outlet end is subtracted to obtain a first target capacity, and then the first target capacity is subtracted by the control pipeline capacity of the first water outlet end, the control pipeline compensation amount of the first water outlet end, the control pipeline capacity of the second water outlet end and the control pipeline compensation amount of the second water outlet end in sequence to obtain the target capacity.

In some embodiments, the calculation formula for the target capacity is as follows:

L_{First target capacity}＝L_{pipeline capacity}+L_{Pipeline compensation amount}-L_{Water quantity circulated}；

L_{Target capacity}＝L_{First target capacity}-L_{Controlling pipeline capacity 1}-L_{Controlling pipeline capacity 2}-L_{Controlling the amount of pipe compensation 1}-L_{Controlling the amount of pipe compensation 2}；

Wherein L _{First target capacity} represents a first target capacity; l _{pipeline capacity} represents the pipeline capacity of the water end; l _{Pipeline compensation amount} represents the pipeline compensation quantity of the water end; l _{Water quantity circulated} represents the circulated water quantity in the first water outlet end; l _{Controlling pipeline capacity 1} represents the control pipeline capacity of the first water outlet end, and L _{Controlling the amount of pipe compensation 1} represents the control pipeline compensation quantity of the first water outlet end; l _{Controlling pipeline capacity 2} represents the control pipeline capacity of the second water outlet end; l _{Controlling the amount of pipe compensation 2} represents the compensation amount of the control pipeline at the second water outlet end.

It can be understood that the above formula is applicable to the case that one or more (e.g., 2,3, etc.) second water outlet ends are discharging water, one or more (e.g., 2,3, etc.) first water outlet ends are circulating (heating up by starting the water pump), and the heating up cycle time when the just opened water outlet ends reach the preset temperature is calculated, and is applicable to the case that the just opened water outlet ends are farthest from the liquid treatment apparatus, the progress situation of each water outlet end can be considered, so that the heating up cycle time required when the just opened water outlet ends reach the preset temperature can be calculated more accurately.

In some embodiments, the fluid circulation control method may further include: showing water time and/or warm-up cycle time.

In some embodiments, it is understood that the water outlet time and the temperature rise time may be displayed only by one or both of them, and in particular may be displayed by a digital display screen or a liquid crystal display screen. The display can be installed on the control panel of the liquid treatment equipment generally, the specific water outlet time of each water outlet end is displayed, and the display can be installed on each liquid circulation control system, so that a user can intuitively observe the time of the water outlet end required to be used through the display. For example, the display may show a water out time of 12:30, the user may wait to 12:30 for taking water. The display may also show the warm-up cycle time, for example, 10 minutes for heating or cooling the liquid; or the display can count down and display the cycle time, for example, the display that the distance from the water outlet time is 2 minutes is remained, so that a user can accurately know the water outlet time of the water outlet end, and the use time is better arranged, for example, when the temperature rising cycle time needs 5 minutes, the user can rest or sweep the floor within the five minutes, and the like, rather than waiting blindly, and the user satisfaction degree and the convenience of using the liquid circulation control system are improved. Further, because the wireless module is arranged in the liquid circulation control, the network can be connected, and therefore, a user can also pass through the electronic product. For example, an application program in a mobile phone or an intelligent home control system can display and monitor, so that a user can view related information anytime and anywhere.
