Specifically, the refrigerant unit is a unit device for achieving heat exchange by circulating a refrigerant. In addition, in the present embodiment, the refrigerant unit is connected to the air cooler and the air conditioner unit, thereby realizing cooling.
The refrigerant unit can comprise a compressor, a condenser, an evaporator, an expansion valve and other parts to form refrigeration circulation, wherein the compressor is used for compressing low-pressure refrigerant into high-pressure gas, liquefying after heat dissipation of the condenser, reducing pressure and temperature through the expansion valve, and finally absorbing heat in the evaporator for evaporation to complete refrigeration circulation.

Further, the indoor temperature can be precisely controlled by adjusting the flow rate and the temperature of the refrigerant solution.
In this embodiment, the refrigerant unit may be connected to the air cooler and the air conditioner unit separately to achieve the purpose of cooling by the air cooler and the air conditioner unit separately, and the refrigerant unit may also be connected in series to the air cooler and the air conditioner unit to achieve the purpose of simultaneously cooling the refrigerant unit and the air cooler in a combined manner. And, the refrigerant unit, the air cooler and the air conditioner unit can be connected by other modes, which is not limited herein.
The refrigerant unit is in working connection with the air conditioning unit, and the air conditioning unit can perform refrigeration by transmitting the refrigerant solution to the air conditioning unit in a refrigeration mode similar to that of an air cooler.
In the embodiment, a refrigerating machine unit is used for transmitting a refrigerant to an air cooler and/or an air conditioner unit so as to perform refrigeration, and an indoor refrigerating system comprises the refrigerating machine unit, the air cooler and the air conditioner unit, wherein the refrigerating machine unit is connected with the air cooler and the air conditioner unit and is used for transmitting the refrigerant to the air cooler and/or the air conditioner unit so as to perform cooling through the air cooler and/or the air conditioner unit. Therefore, the scheme that the refrigerating is carried out by the refrigerants of the same refrigerating unit can be realized, the tail end of the refrigerating unit is simultaneously matched with the air cooler and the air conditioning unit, the indoor temperature adjustment and the indoor cleanliness requirement can be met, the water system is not needed, the air conditioning unit can effectively avoid the problem of dew formation during operation, the air cooler and the air conditioning unit are refrigerated by the same refrigerants, linkage control can be simplified, and the problems that linkage control is complex among multiple sets of systems in the related art, dew formation risk exists in air supply of the combined air conditioning unit, and the air conditioning unit cannot be started are solved.
As an alternative embodiment, as in the indoor refrigeration system, the refrigerant unit is a glycol unit, the refrigerant is a glycol solution, and the air conditioning unit is a combined air conditioning unit. That is, in this embodiment, by using the glycol solution as the refrigerant, the refrigerant unit is a unit for performing the cold cycle through the glycol solution. And the glycol solution is circulated in the indoor refrigeration system to achieve the aim of indoor refrigeration. The system can normally operate even in a very cold environment due to the fact that the glycol has a low freezing point, the cooling system is prevented from freezing in winter, in addition, the glycol has a wide working temperature range, namely, a glycol solution can be kept in a liquid state in the wide temperature range, so that the glycol can adapt to various application requirements, the glycol has good heat conduction performance, heat can be effectively transferred, heat conduction can be rapidly achieved, and therefore efficiency of an indoor refrigerating system in the embodiment is improved, meanwhile, the glycol is stable in chemical property in the wide temperature range and not easy to decompose or deteriorate, the glycol can still keep performance in long-time use, and maintenance cost can be effectively reduced. In this embodiment, the combined air conditioning unit is used as an air conditioning unit, so that dust particles in air can be removed through the primary filter and the secondary filter, and the air humidity in the environment can be adjusted and fresh air can be introduced through the humidifier or the dehumidifier according to the requirement and the preset target humidity, so that the indoor air quality is improved.
As an alternative embodiment, as shown in FIG. 1, the indoor refrigeration system further comprises a first valve, a second valve and a third valve, wherein the first valve is arranged between the refrigerant outflow end of the refrigerant unit and the refrigerant inflow end of the air cooler, the second valve is arranged between the refrigerant outflow end of the air cooler and the refrigerant inflow end of the air conditioner unit, the third valve is arranged between the refrigerant outflow end of the refrigerant unit and the refrigerant inflow end of the air conditioner unit, and the refrigerant outflow end of the air conditioner unit is connected with the refrigerant return end of the refrigerant unit.
That is, when the air cooler and the air conditioning unit are required to perform refrigeration together, the first valve and the second valve can be opened, so that the refrigerant flowing out of the refrigerant outflow end of the refrigerant unit can sequentially pass through the air cooler and the air conditioning unit, and further the purpose of controlling the refrigerant unit to sequentially pass through the air cooler and the air conditioning unit is achieved, that is, after the refrigerant in the refrigerant unit is utilized by the air cooler, the refrigerant can be further utilized by the air conditioning unit, and the purpose of performing cold energy stepped utilization on the refrigerant in the refrigerant unit can be achieved. For example, when the refrigerant unit is a glycol unit and the refrigerant is glycol solution, pipelines between the air cooler and the combined air conditioner unit are connected in series, and the glycol solution sequentially passes through the air cooler and the combined air conditioner unit (the water outlet temperature of the glycol unit is set to default to minus 2 ℃), so that gradient utilization of cold energy is realized.
When only the air conditioning unit is required to refrigerate, the first valve and the second valve can be closed, and the third valve is opened, so that the refrigerant flowing out of the refrigerant outflow end of the refrigerant unit can enter the air conditioning unit, and the aim of refrigerating only through the air conditioning unit is fulfilled. For example, the refrigerant unit is still taken as an ethylene glycol unit, the refrigerant is an ethylene glycol solution as an example, and by closing the first valve and the second valve and opening only the third valve, the ethylene glycol solution cannot enter the air cooler through the first valve and can only enter the air conditioner unit through the third valve, so that refrigeration can only be performed through the air conditioner unit.
Through the system of this embodiment, a way that can refrigerate through air-cooler and air conditioning unit is provided, also provided the way that only refrigerates through air conditioning unit, can effectively promote the application scenario of this system.
As an alternative implementation mode, the indoor refrigeration system further comprises an energy storage assembly, a fourth valve and a fifth valve, wherein the energy storage assembly is used for carrying out cold accumulation, the fourth valve is arranged between a refrigerant outflow end of the refrigerant unit and a refrigerant inflow end of the energy storage assembly, and the fifth valve is arranged between the refrigerant outflow end of the energy storage assembly and the refrigerant inflow end of the refrigerant unit.
In this embodiment, the energy storage assembly is a device for storing cold, and in particular, the energy storage assembly may be a technology for making ice or storing cold using night low-valley power or renewable energy so as to use the stored cold to meet air conditioning or refrigeration demands during daytime or peak hours. The cold accumulation assembly can effectively reduce peak-valley difference of the power grid, improve energy utilization efficiency and reduce operation cost. Alternatively, the energy storage assembly in this embodiment may be a combination of one or more of the following:
1. The ice storage system can further comprise a static ice coil system, a dynamic ice system and an ice crystal system. The static ice coil system is used for setting an ice coil in the cold storage tank, enabling low-temperature water to be frozen into ice in the coil, the dynamic ice system is used for directly making ice in the cold storage tank and storing the ice and water in a mixed mode, and the ice crystal system is used for preparing ice crystals in the cold storage tank and releasing cold energy through dissolution of the ice crystals.
2. The water cold accumulation system can further comprise a cold water storage system and a temperature difference cold accumulation system. The cold water storage system is used for preparing low-temperature water at night low-valley time period and storing the low-temperature water in the cold storage tank, and the temperature difference cold storage system is used for storing cold energy by utilizing the temperature difference between high-temperature water and low-temperature water.
3. A Phase Change Material (PCM) cold storage system uses phase change material (such as saline solution, paraffin wax, etc.) as energy storage medium to store and release cold energy in phase change process.
The energy storage component in the embodiment is connected with the refrigerant unit through a fourth valve and a fifth valve, the fourth valve is arranged between the refrigerant outflow end of the refrigerant unit and the refrigerant inflow end of the energy storage component and used for inputting the refrigerant into the energy storage component from the refrigerant unit, and the fifth valve is arranged between the refrigerant outflow end of the energy storage component and the refrigerant inflow end of the refrigerant unit and used for refluxing the refrigerant used for accumulating the cold of the energy storage component into the refrigerant component. In general, when it is determined that the current valley period is the valley period and there is no need for cooling classification and any air conditioning unit to supply cooling, the refrigerant in the refrigerant unit is transferred to the energy storage assembly to store cold through the energy storage assembly, and the operation of storing cold can be continuously performed until the cold storage of the energy storage assembly reaches the maximum value, and then each device in the embodiment is turned off to stop the system.

That is, in the present embodiment, the air cooler and the air conditioning unit as a whole can be regarded as an air cooling system. And the air refrigerating system is connected with the refrigerant unit through a sixth valve and a seventh valve. The sixth valve is arranged between the refrigerant outflow end of the refrigerant unit and the refrigerant inflow end of the air refrigerating system, the seventh valve is arranged between the refrigerant outflow end of the air refrigerating system and the refrigerant inflow end of the refrigerant unit, and further, the purposes that the refrigerant of the refrigerant unit cannot enter the air refrigerating system and the air refrigerating system stops refrigerating can be achieved by controlling the sixth valve to be closed with the seventh valve.
As an alternative embodiment, the indoor refrigeration system further comprises a solution pump for controlling the flow rate of the refrigerant in the air cooler and/or the air conditioning unit, and the refrigerant outflow end or the refrigerant inflow end of the refrigerant unit is provided with the solution pump. Specifically, since the solution pump is used to control the flow rate of the refrigerant in the air cooler and/or the air conditioning unit, the solution pump may be disposed between the refrigerant outflow end of the refrigerant unit and the refrigerant inflow end of the air cooling system, or between the refrigerant inflow end of the refrigerant unit and the refrigerant outflow end of the air cooling system.

Specifically, the current time can be determined, and the current time is compared with a preset peak electricity time interval and a preset valley electricity time interval to judge whether the current time is a peak electricity time interval or a valley electricity time interval, wherein the peak electricity time interval is a time interval corresponding to a peak electricity consumption period, the valley electricity time interval is a time interval corresponding to a valley electricity consumption period, and the electric charge of the peak electricity time interval is higher than the electric charge of the valley electricity time interval because the electric charge of the peak electricity time interval is only used for cooling.
In this embodiment, when it is determined that the peak electricity period is currently the peak electricity period and there is a combined cooling demand, the refrigerant in the refrigerant unit is transmitted to the air cooler and the air conditioner unit, so that the combined cooling is performed by the air cooler and the air conditioner unit. The combined cooling requirement is the requirement that the air cooler and the air conditioning unit are required to perform refrigeration together, that is, the combined cooling requirement is required to meet the indoor temperature requirement and the indoor cleanliness requirement.
In the embodiment of the application, the refrigerant in the refrigerant unit is transmitted to the air cooler and the air conditioner unit so as to perform combined cooling through the air cooler and the air conditioner unit. Therefore, the scheme that the refrigerating is carried out by the refrigerants of the same refrigerating unit can be realized, the tail end of the refrigerating unit is simultaneously matched with the air cooler and the air conditioning unit, the indoor temperature adjustment and the indoor cleanliness requirement can be met, the water system is not needed, the air conditioning unit can effectively avoid the problem of dew formation during operation, the air cooler and the air conditioning unit are refrigerated by the same refrigerants, linkage control can be simplified, and the problems that linkage control is complex among multiple sets of systems in the related art, dew formation risk exists in air supply of the combined air conditioning unit, and the air conditioning unit cannot be started are solved.
As an alternative implementation manner, the control method can realize the transmission of the refrigerant in the refrigerant unit to the air cooler and the air conditioner unit in the step 101 by controlling the refrigerant unit to sequentially pass through the air cooler and the air conditioner unit so as to perform cold energy stepped utilization on the refrigerant in the refrigerant unit. When the indoor refrigeration system shown in fig. 1 is controlled, if the indoor refrigeration system needs to be refrigerated together through the air cooler and the air conditioner unit, the purpose of controlling the refrigerant unit to sequentially pass through the air cooler and the air conditioner unit can be achieved by controlling to open the first valve and the second valve, under the condition, the refrigerant flowing out of the refrigerant outflow end of the refrigerant unit can sequentially pass through the air cooler and the air conditioner unit, and further the purpose of controlling the refrigerant unit to sequentially pass through the air cooler and the air conditioner unit is achieved, that is, after the refrigerant in the refrigerant unit is utilized by the air cooler, the refrigerant in the refrigerant unit can be further utilized by the air conditioner unit, and therefore the purpose of carrying out gradient utilization of the refrigerating capacity of the refrigerant in the refrigerant unit can be achieved. For example, when the refrigerant unit is a glycol unit and the refrigerant is glycol solution, pipelines between the air cooler and the combined air conditioner unit are connected in series, and the glycol solution sequentially passes through the air cooler and the combined air conditioner unit (the water outlet temperature of the glycol unit is set to default to minus 2 ℃), so that gradient utilization of cold energy is realized.
As an alternative embodiment, the method further comprises the following steps as the control method described above:
In step 201, under the condition that the current temperature of the target environment is determined to be within the target temperature range, maintaining the current running frequency of the solution pump unchanged, and continuing to perform combined cooling, wherein the target environment is a cooling environment of the air cooler and the air conditioner unit, and the solution pump is used for controlling the flow rate of the refrigerant in the air cooler and the air conditioner unit. Alternatively, a sensor for detecting the temperature may be disposed in the target environment to obtain the current temperature T of the target environment, and then the current temperature may be compared with the target temperature range to determine the relationship between the current temperature of the target environment and the target temperature range. The target temperature range may be a temperature range of the target environment after the indoor target temperature T Order of (A) floats up and down according to a temperature deviation value Δt (for example, Δt defaults to 1 ℃ and is adjustable within a range of 0 to 2 ℃), i.e., [ T Order of (A) -△T,T Order of (A) + ]. If the indoor target temperature T Order of (A) -DeltaT is less than or equal to the current temperature T is less than or equal to the indoor target temperature T Order of (A) + DeltaT, the running state of each part of the system is unchanged, the current running frequency of the solution pump is maintained unchanged, and the combined cooling is continued.
In addition, if the current cooling mode is not the combined cooling mode, the current cooling mode is only required to be maintained unchanged. For example, if the current cooling mode is that the energy storage component is used for heat exchange through radiation and the air cooler and the air conditioner unit are used for heat exchange in a combined manner, the cooling mode is continuously maintained for heat exchange through radiation and the air cooler and the air conditioner unit are used for heat exchange in a combined manner, and if the current cooling mode is that the energy storage component is used for heat exchange through radiation and the air conditioner unit is used for heat exchange in a combined manner, the cooling mode is continuously maintained for heat exchange through radiation and the air conditioner unit is used for heat exchange in a combined manner.
And step 202, when the current temperature of the target environment is higher than the upper limit of the target temperature range, increasing the current operating frequency of the solution pump by controlling, so as to increase the refrigeration efficiency of the air cooler and the air conditioning unit. Specifically, when it is determined that the current temperature of the target environment is higher than the upper limit of the target temperature range, it is indicated that the current temperature of the target environment is too high, the cooling efficiency of the air cooler and the air conditioning unit is too low, and the cooling efficiency needs to be increased. That is, if the current temperature T > the indoor target temperature ttmu+Δt (i.e., the upper limit of the target temperature range), the current operating frequency of the solution pump may be increased by controlling to increase the rate at which the refrigerant flows into the air cooler and the air conditioner, thereby increasing the cooling efficiency of the air cooler and the air conditioner, and further, the cooling operating frequency of the solution pump may be gradually increased and observing whether the latest temperature of the target environment is within the target temperature range, if not less than the upper limit of the target temperature range at all times, the current operating frequency of the solution pump may be continuously controlled to be increased until it is maximum.
And 203, reducing the refrigeration efficiency of the air cooler and the air conditioning unit by controlling the current operating frequency of the solution pump under the condition that the current temperature of the target environment is determined to be lower than the lower limit of the target temperature range, and closing the operation of the air cooler under the condition that the latest current temperature of the target environment is still lower than the lower limit of the target temperature range after the duration of reducing the current operating frequency of the solution pump exceeds the preset duration. Specifically, when it is determined that the current temperature of the target environment is lower than the lower limit of the target temperature range, it is indicated that the current temperature of the target environment is too low, the cooling efficiency of the air cooler and the air conditioning unit is too high, and it is necessary to increase and decrease the cooling efficiency. That is, if the current temperature T < the indoor target temperature t—Δt (i.e., the lower limit of the target temperature range), the current operating frequency of the solution pump may be reduced by controlling to reduce the rate at which the refrigerant flows into the air cooler and the air conditioner, thereby reducing the cooling efficiency of the air cooler and the air conditioner. And the duration for reducing the refrigeration efficiency of the air cooler and the air conditioning unit does not exceed the preset duration t1, the preset duration t1 can be preset, and when the real-time temperature of the environment is lower than the lower limit of the target temperature range under the condition of combined cooling of the air cooler and the air conditioning unit, the maximum duration for the air cooler and the air conditioning unit to jointly operate. Furthermore, after the duration of reducing the current operating frequency of the solution pump exceeds the preset duration T1, and the latest current temperature of the target environment is still lower than the lower limit of the target temperature range, if the latest current temperature T New type is smaller than the indoor target temperature T- Δt (Δt defaults to 1 ℃ and 0-2 ℃ is adjustable), the operation of the air cooler can be closed by controlling to close the first valve and the second valve and only open the third valve as shown in fig. 1, and the tail end is only cooled by the air conditioning unit, or the air conditioning unit and the energy storage component can be combined for cooling under the condition that the energy storage component can still exchange heat by radiation.
As an alternative embodiment, the control method as described above, the method further includes the step of transmitting the refrigerant in the refrigerant unit to the energy storage assembly to store the cold through the energy storage assembly until the cold storage of the energy storage assembly reaches a maximum value when the current valley period is determined and there is no cold supply demand, wherein the cold supply demand is a demand for cooling through at least one of the air cooler and the air conditioner unit.
In this embodiment, the energy storage assembly is a device for storing cold, and in particular, the energy storage assembly may be a technology for making ice or storing cold using night low-valley power or renewable energy so as to use the stored cold to meet air conditioning or refrigeration demands during daytime or peak hours. The cold accumulation assembly can effectively reduce peak-valley difference of the power grid, improve energy utilization efficiency and reduce operation cost. Alternatively, the energy storage assembly in this embodiment may be a combination of one or more of an ice storage system that may further include a static ice coil system, a dynamic ice system, and an ice crystal system. The static ice coil system is used for setting an ice coil in the cold storage tank, enabling low-temperature water to be frozen into ice in the coil, the dynamic ice system is used for directly making ice in the cold storage tank and storing the ice and water in a mixed mode, and the ice crystal system is used for preparing ice crystals in the cold storage tank and releasing cold energy through dissolution of the ice crystals. The water cold accumulation system can further comprise a cold water storage system and a temperature difference cold accumulation system. The cold water storage system is used for preparing low-temperature water at night low-valley time period and storing the low-temperature water in the cold storage tank, and the temperature difference cold storage system is used for storing cold energy by utilizing the temperature difference between high-temperature water and low-temperature water. A Phase Change Material (PCM) cold storage system uses phase change material (such as saline solution, paraffin wax, etc.) as energy storage medium to store and release cold energy in phase change process.
Because the fourth valve is arranged between the refrigerant outflow end of the refrigerant unit and the refrigerant inflow end of the energy storage component and is used for inputting the refrigerant into the energy storage component by the refrigerant unit, and the fifth valve is arranged between the refrigerant outflow end of the energy storage component and the refrigerant inflow end of the refrigerant unit and is used for refluxing the refrigerant which is used for accumulating cold in the energy storage component into the refrigerant component, the energy storage component can be connected with the refrigerant unit through the opened fourth valve and the opened fifth valve in a mode of controlling the fourth valve and the fifth valve to be opened and closing the sixth valve and the seventh valve under the condition that the requirement of cooling by at least one of the air cooler and the air conditioner unit is not determined. In addition, in this embodiment, when it is determined that the current valley period is the valley period and there is no need for cooling classification and any one of the air conditioning units (i.e., no need for cooling), the refrigerant in the refrigerant unit is transferred to the energy storage component, so that the energy storage component is used to store cold, and the cold storage operation can be continuously performed until the cold storage of the energy storage component reaches the maximum value, and then each device in this embodiment is turned off, so that the system stops running.
