Description

Air-conditioning component and combined control method thereof

technical field

The invention relates to the technical field of air treatment, in particular to an air conditioner assembly and a joint control method thereof.

Background technique

An air conditioner usually has a cooling mode and a heating mode. Through the circulation of the refrigerant in the circuit formed by the compressor-condenser-throttling component (such as an electronic expansion valve or capillary tube, etc.)-evaporator-compressor, it can flow to the room. The space provides cooling or heating, thereby lowering or raising the temperature of the interior space. The switching between the cooling mode and the heating mode is accomplished through the switching of the four-way valve. Specifically, the flow path of the refrigerant in the circuit is switched through the four-way valve, so that: when the air conditioner is in the cooling mode, the indoor heat exchanger is an evaporator and the outdoor heat exchanger is a condenser; while the air conditioner is in the heating mode , the indoor heat exchanger is a condenser and the outdoor heat exchanger is an evaporator.

If the air conditioner is in the above-mentioned cooling mode and heating mode for a long time, since the air in the indoor space is always circulated, the air quality will be deteriorated. In view of this, there are air conditioners that add fresh air modules at present. The fresh air module mainly introduces the air from the outdoor environment into the indoor space, so as to improve the air quality by partially replacing and updating the air used for circulation in the indoor space.

When fresh air is introduced through the fresh air module, if the function of introducing fresh air and the cooling/heating function are implemented independently (such as temporarily sacrificing the cooling/heating function during the introduction of fresh air), the indoor space will be affected. have a certain impact on user experience.

Correspondingly, a new technical solution is needed in the art to solve the above problems.

Contents of the invention

technical problem

In view of this, the technical problem to be solved by the present invention is to provide an air-conditioning assembly and a joint control method thereof that can improve the experience of users in indoor spaces during the fresh air function.

solution

The first aspect of the present invention provides a combined control method for an air-conditioning assembly, the air-conditioning assembly includes an air conditioner capable of adjusting the temperature of indoor air and a new fan capable of exchanging outdoor air and indoor air, the new The fan includes a first air duct, a second air duct, and a heat exchange core belonging to the first air duct and the second air duct, and the first air duct is equipped with a first fan so that the The outdoor air in the outdoor environment is introduced into the indoor space through the first air duct, and the second air duct is equipped with a second fan, so that the indoor air in the indoor space is drawn out to the outdoor environment through the second air duct through the second fan , the joint control method includes: when the air conditioner is in the heating mode, detecting the indoor temperature; when the indoor temperature is not lower than the set temperature, turning on the first fan and the second fan.

Through such setting, it is possible to effectively prevent the deterioration of the heating effect due to the introduction of fresh air. For example, the set temperature can be a certain lower value, such as -10°C.

It should be noted that those skilled in the art can select the start-up timing and respective operation modes of the first fan and the second fan according to the actual situation, as long as the air exchange volumes are roughly the same. As an example, the rules of the first fan and the second fan are the same, they are turned on at the same time, and the operation mode is always consistent.

Regarding the joint control method of the above-mentioned air-conditioning components, in a possible implementation manner, the "when the indoor temperature is not lower than the set temperature, turn on the first fan and the second fan" includes: When the indoor temperature is not lower than the set temperature and the indoor temperature has not reached the target temperature, the first fan and the second fan are turned on.

Through such a setting, it can be ensured that the indoor space can obtain higher-quality air when the temperature reaches the standard.

Specifically, during the operation of the air-conditioning components, the fan is used as the auxiliary of the air conditioner, and actively improves the air quality while the air conditioner is heating according to the user's requirements. Therefore, the users of the indoor environment can obtain the air whose temperature reaches the standard and whose quality is improved.

Regarding the joint control method of the above-mentioned air-conditioning components, in a possible implementation manner, the "when the indoor temperature is not lower than the set temperature and the indoor temperature has not reached the target temperature, turn on the first fan and the The "second fan" includes: when the indoor temperature is not lower than the set temperature and the indoor temperature has not reached the target temperature, comparing the difference between the indoor temperature and the target temperature; when the difference is not greater than the first set temperature difference In some cases, the first fan and the second fan are turned on.

Compared with the cooling demand, when the heating demand does not meet the standard, it will have a greater impact on the user experience of the indoor space. For example, when the heating demand is not satisfied, turning on the fresh air function will make the indoor space users feel uncomfortable. The feeling of "the cold wind in winter" is similar to "the house leaks and it rains all night". Therefore, when the heating demand is not met to a small extent, it is a more scientific choice to temporarily abandon the introduction of fresh air, regardless of whether the user is asked or not. Usually the first set temperature difference is a relatively large value, such as a certain value between 5-15°C (eg, 10°C).

Therefore, through such setting, the quality of the air can be improved when the heating demand is satisfied to a greater extent. In this way, the air quality can be actively improved on the premise of satisfying the user's temperature requirements to a greater extent, thereby seeking to more reasonably improve the user's experience in the indoor space.

Regarding the joint control method of the above-mentioned air-conditioning components, in a possible implementation manner, the "when the indoor temperature is not lower than the set temperature, turn on the first fan and the second fan" includes: Determine the rising speed of the indoor temperature; if the rising speed is lower than the set speed, at least reduce the rotation speed of the first fan.

With such a setting, the degree to which the heating experience of the indoor space is affected due to the introduction of too much outdoor air is reduced as much as possible by reducing the introduced outdoor air in time.

It should be noted that the set speed is usually a small value, which is different from the reduced value in the physical sense. The set speed here can also be a negative value, that is, when too much outdoor air is introduced into the indoor space , the temperature of the room air may drop. Normally, the set speed is a value between -5-1°C, such as -3°C.

It can be understood that reducing the rotational speed of the first fan may be continuous reduction, stepwise reduction by time periods, and the like. In addition, under the premise of reducing the amount of outdoor air introduced, it is not necessary to simultaneously ensure the same amount of indoor air discharge. For example, the rotation speed of the first fan is reduced stepwise in two stages, and the rotation speed of the second fan is roughly kept constant.

Regarding the joint control method of the above-mentioned air-conditioning components, in a possible implementation manner, the "when the rising speed is lower than the set speed, at least reduce the speed of the first fan" includes: When the rising speed is lower than the set speed, reduce the rotation speed of the first fan; make the rotation speed of the second fan consistent with the rotation speed of the first fan.

Through such a setting, a relatively simple speed adjustment strategy is given, and the adjustment method with consistent speed can achieve better operation stability of the fresh air fan.

Regarding the joint control method of the above-mentioned air-conditioning components, in a possible implementation manner, the "when the rising speed is lower than the set speed, at least reduce the speed of the first fan" includes: When the rising speed is lower than the set speed, reduce the rotation speed of the first fan; make the second fan run at intervals with the rotation speed divided into sections.

Through such a setting, an adjustment strategy is given in which the speeds of fans near the indoor side and near the outdoor side are different.

It can be understood that, the second blower fan may be operated at intervals in different speed segments: run at different fixed speeds for corresponding time segments; some time segments have fixed speeds, while others have variable speeds, That is to say, further speed adjustment is included in a certain time zone; if the speed in a certain zone is zero, it will stop in this time zone.

Regarding the joint control method of the above-mentioned air-conditioning components, in a possible implementation manner, the "when the indoor temperature is not lower than the set temperature and the indoor temperature has not reached the target temperature, turn on the first fan and the The "second fan" includes: increasing the speed of the first fan when the outdoor temperature is higher than the indoor temperature.

Through such a setting, the realization of the heating effect is promoted by increasing the "ready-made" high-temperature wind as much as possible.

Regarding the joint control method of the above-mentioned air-conditioning components, in a possible implementation manner, the fresh air fan is provided with a third air passage, the upstream side of the third air passage communicates with the indoor space, and the third air passage The downstream side of the air channel is connected with the first air channel, and the upstream side of the third air channel is equipped with a bypass air door. Turning on the first fan and the second fan includes: opening the bypass air door when the outdoor temperature is higher than the indoor temperature.

Through such a setting, in the process of increasing the "ready-made" high-temperature wind, the temperature change is softer by introducing the air in the indoor space, thereby avoiding the occurrence of the "ready-made" high-temperature wind accompanied by the rapid introduction. The phenomenon of thermal shock appears in the user's experience of the indoor space caused by the rapid temperature rise.

Regarding the joint control method of the above-mentioned air-conditioning assembly, in a possible implementation manner, the air-conditioning assembly further includes a humidity adjustment module, and the control method includes: when the indoor temperature is not lower than the set temperature, or when the indoor temperature does not reach the target temperature And when the difference between the indoor temperature and the target temperature decreases to the second set temperature difference, the humidity adjustment module is turned on to adjust the humidity of the air in the indoor space.

Through such a setting, a temperature-priority temperature-humidity joint adjustment scheme is given. Usually, the second set temperature difference is a certain value between 2-5°C (such as 2°C). As mentioned above, when the air conditioner is in the heating mode, it is possible to improve other aspects such as humidity and quality when the heating demand is largely met.

The second aspect of the present invention provides an air-conditioning assembly, which includes a control module, wherein the control module is used to implement the combined control method for the air-conditioning assembly described in any one of the preceding items.

It can be understood that the air-conditioning assembly has all the technical effects of the joint control method of the air-conditioning assembly described above, which will not be repeated here.

Detailed ways

Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

It should be noted that, in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" etc. The terms of the indicated direction or positional relationship are based on the direction or positional relationship shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation , and therefore cannot be construed as a limitation of the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and should not be understood as indicating or implying relative importance.

Referring to FIG. 1 , FIG. 1 shows a schematic structural diagram of an air-conditioning assembly according to an embodiment of the present invention. As shown in Figure 1, the air conditioner assembly 100 mainly includes an air conditioner 1, a fresh air blower 2 and a humidification adjustment module 3, wherein the air conditioner is mainly used for air temperature adjustment, and the fresh air blower is mainly used for the introduction of fresh air and humidity adjustment. The module focuses on the regulation of air humidity.

The air conditioner 1 usually includes an outdoor part and an indoor part (for example, for a window machine, the indoor part and the outdoor part belong to an integrated machine with an integrated arrangement in physical structure, and the pipes connecting the outdoor part and the indoor part are also integrated in the integrated machine. For general models such as cabinet machines, hanging ceiling machines, etc., the outdoor part and the indoor part are usually arranged in the outdoor space and the indoor space in a split design, and the pipes connecting the outdoor part and the indoor part are set through the wall), and the outdoor part It mainly includes compressor, outdoor fan and outdoor heat exchanger (usually called condenser), and the indoor part mainly includes indoor heat exchanger (usually called evaporator), indoor fan and electric control box, etc., compressor-condenser- The evaporator-compressor forms a refrigerant circulation loop. When the refrigerant circulates along the compressor→outdoor heat exchanger→indoor heat exchanger→compressor, the air conditioner is in a refrigeration cycle. When the refrigerant circulates along the compressor→indoor heat exchanger→outdoor heat exchanger→compressor, the air conditioner is in a heating cycle.

It can be seen that, in the process of cooling mode or heating mode, the air conditioner regulates the temperature of the air in the indoor space as follows: under the action of the indoor fan, the air in the indoor space passes through the air inlet (such as the air inlet grid) into the shell, and conduct convective heat exchange with the surface of the indoor heat exchanger in the shell (in the heating mode, the indoor heat exchanger is functionally a condenser, so the air absorbs heat and heats up; in the cooling mode, the indoor heat exchanger is evaporator, so the air releases heat and cools down), and then is sent into the indoor space through the air outlet. The casing is usually equipped with swing vanes and wind deflectors to adjust the air outlet direction at the position corresponding to the air outlet. Since the air in the indoor space is always cyclically adjusted during the temperature adjustment process, and as a common sense, the air conditioner should try to keep the indoor part in a closed state during the cooling and heating operation, so it is relatively difficult for the air conditioner to continue cooling and heating operation. After a long time, the air quality has declined. At this time, the air quality of the indoor space can be improved by introducing air from the outdoor environment (fresh air) into the indoor space, and the fresh air blower 2 is therefore configured.

The fresh air fan 2 is usually a fresh air, exhaust air and ventilation equipment containing a heat exchange core. It mainly recovers the waste heat in the exhaust to preheat or precool the fresh air introduced into the room. When the fresh air enters the indoor space or the air conditioner Reduce (increase) the enthalpy of fresh air before the surface cooler of the device is subjected to heat and humidity treatment.

The humidity adjustment module 3 can be a separate module (such as a humidifier), or it can be set by setting the pipeline of the air conditioner and the pipeline switching mechanism, and planning the refrigerant circuit so that the air conditioner can When the refrigerant circuit is used, the corresponding humidity adjustment function can be realized.

Referring to FIG. 2 , FIG. 2 shows a schematic structural diagram of a new fan in an air-conditioning assembly according to an embodiment of the present invention. As shown in FIG. 2 and according to the orientation in FIG. 2 , the fresh air blower 2 includes a housing, a first air duct 211 , a second air duct 212 , and heat exchangers belonging to the first air duct and the second air duct. The core body 22, the downstream side of the first air passage, that is, the upper right in the figure is equipped with a first fan 231, so that the outdoor air of the outdoor environment can be introduced into the indoor space through the first air passage through the first fan, and the second air passage The downstream side, that is, the upper left in the figure, is equipped with a second fan 232, so that the indoor air in the indoor space can be led out to the outdoor environment through the second air duct through the second fan.

When the fresh air fan is working, the first air channel corresponding to the introduction of fresh air and the second air channel corresponding to the indoor exhaust air flow through the heat exchanger core in a crossed (heat exchangeable) but non-interfering (non-mixing) manner. , due to the temperature difference and steam partial pressure difference in the airflow on both sides of the airflow partition plate, when the two airflows pass through the partition plate, heat and mass transfer phenomenon occurs, causing a total heat exchange process. For example, when the fresh air fan operates in the cooling mode in summer, the fresh air obtains cooling capacity from the indoor exhaust air, the temperature drops, and at the same time, it is dried by the indoor exhaust air, and the moisture content decreases. When running in cooling mode in winter, the fresh air gets heat from the indoor exhaust air, and the temperature rises. In this way, through the total heat exchange process of the heat exchange core, effective energy can be recovered from the indoor exhaust air of the air conditioner during the process of introducing fresh air.

As an improvement, a third air duct (not shown) is also provided on the fresh air machine. Specifically, the upstream side of the third air duct communicates with the indoor space, and the downstream side of the third air duct communicates with the first air duct. A bypass air door is arranged on the upstream side of the third air duct. In this way, when the bypass air door is opened, a part of the air in the indoor space can be introduced into the first air duct, mixed with fresh air, and then sent into the indoor space.

The situations that require the introduction of fresh air mainly include the following two types:

One is the situation where there is no need to adjust the temperature of the indoor space (for example, the indoor and outdoor ambient temperatures are roughly the same, so there is no need for cooling and heating), at this time, the air quality of the indoor space can be improved only by the operation of the fresh air fan. Since the air conditioner does not need to introduce a heat exchange mechanism at this time, the operating parameters of the fresh air unit can first be raised and stabilized to the highest gear corresponding to the target operating parameters, and run in this state for a certain period of time (such as 30min) and then shut down. Can.

The other is the situation where it is necessary to adjust the temperature of the indoor space (for example, the ambient temperature inside and outside the room is obviously different, so there is a need for cooling and heating). Air. In this case, in order to prevent the temperature change brought by the fresh air introduced from the outdoor environment from affecting the heat transfer mechanism of the air conditioner and thereby affecting the user experience, after the fresh air fan is running stably, its operation mode should be adjusted according to the heat transfer mechanism. For example, the operating parameters of the fresh air blower should first be raised and stabilized to the highest gear corresponding to the target operating parameters. In theory, the fresh air blower should be operated in this state for a certain period of time (such as 15 minutes). However, when the temperature difference between the current indoor temperature and the target temperature corresponding to the heat exchange mechanism is 5-10°C, the operating gear of the fresh air fan is lowered, and when the current indoor temperature and the target temperature corresponding to the heat exchange mechanism When the temperature difference is greater than 10°C, the fresh air unit will be closed no matter whether it reaches 15 minutes or not.

The present invention mainly aims at the second situation, especially when the air conditioner is in the heating mode, and improves user experience in the indoor space through joint control of the air conditioner, fresh air fan and humidity adjustment module.

It can be understood that, on the premise of ensuring the realization of functions, the physical composition and layout of the three parts can be flexibly set. For example, the three parts can be set separately, or some or all of them can be properly integrated. . In this embodiment, the three parts of the air-conditioning assembly are set separately and there are no related elements that affect each other in physical orientation among the three parts. Obviously, this is only an exemplary description, such as setting the relative positions of each part separately They can be related to a certain extent, for example, the fresh air blower can be set upstream of the air conditioner, etc.

Based on the above structure, the air conditioner assembly further includes a control module, and the control module can be used to perform the following control method on the air conditioner assembly, so as to improve the experience of users in the indoor space when the air conditioner assembly needs to introduce fresh air into the indoor space.

In the description of the present invention, "module" and "processor" may include hardware, software or a combination of both. A module may include hardware circuits, various suitable sensors, communication ports, memory, and may also include software parts, such as program codes, or a combination of software and hardware. The processor may be a central processing unit, a microprocessor, an image processor, a digital signal processor or any other suitable processor. The processor has data and/or signal processing functions. The processor can be implemented in software, hardware or a combination of both. The non-transitory computer readable storage medium includes any suitable medium that can store program code, such as magnetic disks, hard disks, optical disks, flash memory, read only memory, random access memory, and the like.

Those skilled in the art can understand that all or part of the process in the control method of the present invention can also be completed by instructing related hardware through a computer program, and the computer program can be stored in a computer-readable storage medium , when the computer program is executed by the processor, it can realize the steps of the above-mentioned various method embodiments. Wherein, the computer program includes computer program code, and the computer program code may be in the form of source code, object code, executable file or some intermediate form. The computer-readable medium may include: any entity or device capable of carrying the computer program code, medium, U disk, removable hard disk, magnetic disk, optical disk, computer memory, read-only memory, random access memory, electrical carrier signal , telecommunication signals, and software distribution media. It should be noted that the content contained in the computer-readable medium may be appropriately increased or decreased according to the requirements of legislation and patent practice in the jurisdiction. For example, in some jurisdictions, computer-readable media Excludes electrical carrier signals and telecommunication signals.

Further, it should be understood that since the setting of the control module is only to illustrate the functional units of the system of the present invention, the physical device corresponding to the control module may be the processor itself, or a part of software or hardware in the processor, Or part of a combination of software and hardware. Therefore, the number of control modules being one is merely illustrative.

Those skilled in the art can understand that the control module can be split adaptively according to the actual situation. The specific splitting form of the control module will not cause the technical solution to deviate from the principle of the present invention, therefore, the technical solutions after splitting will all fall within the protection scope of the present invention.

Referring to FIG. 3 , FIG. 3 shows a schematic flowchart of a joint control method for air-conditioning components according to an embodiment of the present invention. As shown in Fig. 3, the combined control method of the air conditioning components includes the following steps:

S31. When the air conditioner is in the heating mode, detect the indoor temperature; the indoor temperature is not lower than the set temperature, the indoor temperature has not reached the target temperature, and the difference between the two is not greater than the first set temperature difference In the case of , turn on the first blower fan and the second blower fan.

For example, in this embodiment, the set temperature is -10°C, the first set temperature difference is 10°C, the first fan and the second fan are turned on synchronously and run at a preset reasonable speed, and the operating parameters after turning on Always adjust synchronously.

Through such an arrangement, it is possible to provide higher-quality air to users in the indoor space while preventing the reduction of the heating effect as much as possible.

Usually, in the process of introducing fresh air, the indoor temperature rises slowly but still maintains an upward trend. At this time:

S32. Determine the rising speed of the indoor temperature. If the rising speed is greater than the set speed, skip to S33. If the rising speed is less than or equal to the set speed, keep the current speed and continue to run.

As in this embodiment, the rising speed is -3°C/min.

S33. Decrease the speed of the first fan and adjust the speed of the second fan synchronously.

For example, in a possible implementation manner, a PID adjustment method may be adopted to adjust the decrease of the rotational speeds of the (first and second) fans according to the decrease speed of the indoor temperature. Obviously, this is only an exemplary description, and those skilled in the art can also use other existing or specially formulated methods to adjust the speed reduction of the (first, second) fans. For example, the speed of the (first, second) fan includes certain fixed speeds. When the speed of the (first, second) fan needs to be reduced, the speed is reduced stepwise and the speed is reduced once. The speed of the (first, second) fan is adjusted in a manner of only one step down.

In winter, in the process of introducing fresh air, the outdoor temperature is usually lower than the indoor temperature. However, assuming that the outdoor temperature is higher than the indoor temperature, at this time, the process of introducing pure fresh air is essentially an indoor temperature. The process of increasing the temperature, therefore, the joint control method may also include the following steps:

When the outdoor temperature is higher than the indoor temperature, the speed of the first fan is increased.

In the process of introducing the ready-made high-temperature fresh air, the increase of the rotational speed will be accompanied by the concentrated input of heat, which may make the users of the indoor space feel thermal shock. Considering this, the upstream side configuration of the third air duct can be opened The bypass air door is designed to reduce or even completely avoid the phenomenon that the user feels the thermal shock.

At the same time, the joint control method of the air-conditioning assembly of the present invention also includes the step of humidity adjustment, specifically:

When the indoor temperature does not reach the target temperature and the difference between the target temperature and the target temperature decreases to a second set temperature difference, the humidity adjustment module is turned on to adjust the humidity of the air in the indoor space. As in this embodiment, the second set temperature difference is 2°C.

It can be seen that in the technical solution of this embodiment, on the premise that the user in the indoor space chooses temperature priority, during the process of adjusting the temperature of the indoor air by the air conditioner, the outdoor air and part of the indoor air are separated by the fresh fan. Interchangeable, improving the quality of indoor air. Through the control of air exchange and humidity adjustment, the user experience of the indoor space is improved. Specifically, the freshness of the air is improved on the basis of ensuring the air of the user's expected temperature and humidity.

It should be pointed out that, although the steps are described in a specific order in the above embodiments, those skilled in the art can understand that in order to achieve the effect of the present invention, different steps do not have to be executed in this order. It can be performed simultaneously or in other orders, and some steps can also be added, replaced or omitted, and these changes are all within the protection scope of the present invention.

It should be noted that although the control method constituted in the above specific manner is used as an example for introduction, those skilled in the art can understand that the present invention should not be limited thereto. In fact, users can flexibly adjust relevant steps, parameters in steps and other elements according to actual application scenarios and other situations.

So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings, but those skilled in the art will easily understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
