In order to achieve the dehumidification effect, the evaporation temperature of each air conditioning device needs to be limited below a certain value. The reduction of the evaporation temperature will lead to a passive increase in the heat exchange temperature difference and an increase in the compression ratio of the compressor, thereby increasing energy consumption, which affects the overall energy efficiency of the air conditioning device.

[0028] Existing heating, ventilation, and air conditioning (HVAC) equipment, such as air conditioning systems, still has some limitations and challenges in terms of dehumidification and energy efficiency. For example, when there are multiple air conditioning units in the same space, each air conditioning unit operates independently according to its own control logic. For instance, split wall-mounted and cabinet air conditioners, which are typically designed as independent operating systems, each have their own compressors and control systems. They independently adjust according to the temperature requirements of their respective spaces and do not have the ability to work collaboratively. To achieve the dehumidification effect, the evaporation temperature of each air conditioning unit needs to be restricted below a certain value. The reduction of the evaporation temperature will lead to a passive increase in the heat transfer temperature difference and an increase in the compression ratio of the compressor, thereby increasing energy consumption, which affects the overall energy efficiency of the air conditioning equipment.

[0029] To solve the above problems, the embodiments of the present application provide a method and system for collaborative control of HVAC equipment. By using an electronic device to perform collaborative control on multiple sets of HVAC equipment in the same space, the multiple sets of HVAC equipment are divided into at least two categories, and each category of equipment has a different operating mode, thereby realizing the collaborative operation of multiple sets of HVAC equipment in the same target space. In this way, the HVAC equipment no longer operates independently but classifies and collaborates according to preset conditions and allocation information, which can optimize the overall operating efficiency and reduce the increase in energy consumption caused by separate control of the HVAC equipment. That is, the embodiments of the present application can improve the system energy efficiency. Moreover, the embodiments of the present application control each HVAC equipment to perform corresponding actions according to its own control signal, so that the environmental parameters in the target space meet the preset indicators, which can accurately control the environmental parameters (such as environmental humidity) and improve the user's comfort. That is, the embodiments of the present application can also achieve the collaborative optimization of energy efficiency and environmental parameter control.

[0030] Figure 1 The flowchart showing the steps of a method for collaborative control of HVAC equipment provided by the embodiments of the present application is referred to Figure 1 , and the execution subject of this method can be an electronic device, such as a terminal or a controller. The terminal or the controller is connected to the HVAC equipment to send control signals to the HVAC equipment.

[0031] Specifically, a method for collaborative control of HVAC equipment provided by the embodiments of the present invention includes the following steps S101 - S102:

[0032] S101. Determine the allocation information according to the HVAC equipment meeting the preset conditions. The allocation information is used to divide multiple sets of HVAC equipment into at least two categories, and each category of HVAC equipment has a different operating mode. The multiple sets of HVAC equipment are located in the same target space;

[0033] In this embodiment, the preset conditions are used to represent the constraint conditions for the coordinated operation of multiple sets of HVAC equipment. The preset conditions include, but are not limited to, receiving a control signal from the user, the current operating mode of the HVAC equipment, the energy consumption limit parameters for the operation of the HVAC equipment, etc., and can be specifically customized by the user. In one example, the preset condition is, for example, receiving an energy-saving control instruction from the user, or the output energy consumption of the HVAC equipment exceeding the preset energy consumption, etc.

[0034] The HVAC equipment in this embodiment includes a heating, ventilation, and air conditioning system, such as an air conditioning unit. The air conditioning unit includes an indoor unit and an outdoor unit. The HVAC equipment is connected to an electronic device so that the electronic device can send control signals to each air conditioning unit. The HVAC equipment is also provided with an environmental monitoring device, such as a humidity detector, a temperature monitor, etc., to monitor the environmental parameters in the space. The environmental monitoring device can be set near the HVAC device or at any target position in the target space where a user wants to control the environment.

[0035] The target space can be a room, the same meeting room, the same floor, etc., which are spaces that can be air-connected. Multiple sets of HVAC equipment in this embodiment are located in the same target space, and the environmental parameters in the target space can be controlled by coordinating the control of the multiple sets of HVAC equipment.

[0036] The allocation information in this embodiment is used to divide multiple sets of HVAC equipment into at least two categories, and each category of HVAC equipment has a different working mode. Specifically, the allocation information can be randomly allocated or preset allocation data. For example, in a large meeting room, 5 air conditioning units are installed, and each unit is responsible for adjusting the environment in different areas of the meeting room. During the operation of the 5 air conditioning units, if the preset conditions for energy-saving operation are met and energy saving needs to be achieved during the dehumidification process, 2 air conditioning units are randomly allocated to operate in the dehumidification mode, and the remaining 3 air conditioning units operate in the cooling mode.

[0037] In another example, the allocation information can also be specified by the user. For example, while receiving an energy-saving control instruction from the user, the user sends allocation information, which can be "Air conditioning unit A operates in the dehumidification mode, and air conditioning units B, C, D, and E operate in the cooling mode".

[0038] S102. Determine the control signals for each HVAC equipment according to the allocation information, and control each HVAC equipment to perform corresponding actions according to the control signals, so that the environmental parameters in the target space meet the preset indicators.

[0039] Continuing with the above example, if the allocation information includes "Air conditioner unit A operates in the dehumidification mode, and air conditioner units B, C, D, and E operate in the cooling mode", then the control signal for air conditioner unit A is a control signal for controlling air conditioner unit A to turn on the dehumidification mode. This control signal includes, but is not limited to, the temperature of the heat exchanger of the air conditioner unit, the fan speed, the compressor frequency, the evaporation temperature, the opening degree of the electronic expansion valve, etc., so that air conditioner unit A can perform corresponding actions according to the control signal and be in the dehumidification mode.

[0040] Similarly, the control signals for air conditioner units B, C, D, and E are control signals for controlling air conditioner units B, C, D, and E to turn on the cooling mode, including, but not limited to, the temperature of the heat exchanger, the fan speed, the compressor frequency, the evaporation temperature, the opening degree of the electronic expansion valve, etc., so that air conditioner units B, C, D, and E can perform corresponding actions according to the control signal and be in the cooling mode.

[0041] In this embodiment, the environmental parameters in the target space meet the preset indicators. For example, the environmental parameters in the target space need to maintain the temperature at 24°C ± 1°C and the humidity at 40% ± 5%. When the environmental parameters meet the preset indicators, each HVAC device can maintain its current operating state. When the environmental parameters exceed the preset indicators, the environmental parameters in the target space can be dynamically adjusted by adjusting the control signals of each HVAC device to maintain a comfortable environment in the target space.

[0042] In the above embodiment, by coordinating the control of multiple HVAC devices in the same space, by dividing the multiple HVAC devices into at least two categories, and each category of devices has different operating modes, the coordinated operation of multiple HVAC devices in the same target space is realized. In this way, the HVAC devices no longer operate independently, but are classified and coordinated according to preset conditions and allocation information, which can optimize the overall operating efficiency, reduce the energy consumption increase caused by individual control of HVAC devices, realize the energy efficiency control of multiple HVAC devices, and save the overall energy efficiency of multiple HVAC devices.

[0043] In the embodiment of the present application, according to the HVAC device meeting the preset conditions, the allocation information is determined, including: according to receiving an energy-saving control instruction and the HVAC device being in the cooling state, it is determined that the allocation information includes dividing multiple HVAC devices into dehumidification-type devices and sensible heat treatment-type devices. The dehumidification-type devices are used to reduce the humidity in the target space, and the sensible heat treatment-type devices are used to reduce the temperature in the target space; wherein, the number of dehumidification-type devices is greater than or equal to 1 and the ratio of the number of dehumidification-type devices to the total number of HVAC devices is less than the first preset proportion.

[0044] In one example, the dehumidification principle of the air-conditioning unit is that during the refrigeration process of the air conditioner, air flows over the surface of the cold coil. The temperature of the coil surface is lower than the dew point temperature of the air, causing water droplets to condense on the coil surface. This can convert the water vapor in the room into water, which is then discharged outdoors through the air-conditioning pipeline, thereby effectively reducing the indoor humidity.

[0045] When the HVAC equipment is used as sensible heat treatment equipment, the air-conditioning unit transfers the indoor heat to the outdoors through the circulation of the refrigerant and air flow, thereby reducing the indoor temperature and being used to lower the temperature in the target space.

[0046] As can be seen from the above, the operation of the air-conditioning unit is independently controlled. When multiple air conditioners in the same space operate at the same evaporation temperature, the energy efficiency cannot reach the optimal level. Moreover, the higher the environmental humidity, the lower the refrigeration efficiency of the air-conditioning system usually is, and at the same time, it may increase energy consumption and lead to an increase in indoor environmental discomfort. Therefore, in this embodiment, when all the HVAC equipment is in the refrigeration state and the electronic device receives an energy-saving control instruction sent by the user, it is determined that the allocation information includes classifying multiple sets of HVAC equipment into dehumidification equipment and sensible heat treatment equipment. The dehumidification equipment is used to reduce the humidity in the target space, and the sensible heat treatment equipment is used to reduce the temperature in the target space.

[0047] On the one hand, in the refrigeration mode, the air-conditioning unit has already controlled the indoor temperature. At this time, by classifying the HVAC equipment, the humidity and temperature can be controlled more precisely, achieving more refined environmental control, improving the user's comfort and meeting specific environmental requirements. On the other hand, by classifying the HVAC equipment into dehumidification and sensible heat treatment categories, more targeted energy management can be carried out to achieve energy conservation.

[0048] Among them, the number of dehumidification equipment is greater than or equal to 1 and the ratio of the number of dehumidification equipment to the total number of HVAC equipment is less than the first preset proportion. For example, if there are 5 air-conditioning units in the target space, then 1 unit is used as the dehumidification unit, and the other 4 units are used as sensible heat treatment units.

[0049] In this embodiment, the ratio of the number of dehumidification equipment to the total number of HVAC equipment is less than the first preset proportion, which can ensure that there are enough equipment to handle the humidity and prevent the reduction of energy efficiency caused by excessive allocation of dehumidification equipment. In one example, the first preset proportion can be 50%.

[0050] In the above embodiments, multiple sets of HVAC equipment are divided into dehumidification equipment and sensible heat treatment equipment. The dehumidification equipment is used to reduce the humidity in the target space, and the sensible heat treatment equipment is used to reduce the temperature in the target space. By controlling the quantity range of the dehumidification equipment, more targeted energy efficiency management can be carried out, achieving energy conservation and more precise control of humidity and temperature, realizing more refined environmental control, improving the user's comfort and meeting specific environmental requirements.

[0051] In the embodiments of the present application, according to the allocation information, the control signals of each HVAC equipment are determined, including: obtaining the initial control signals of each HVAC equipment corresponding to the allocation information as the control signals of each HVAC equipment; the initial control signals include the dehumidification signals corresponding to the dehumidification equipment and the sensible heat treatment signals corresponding to the sensible heat treatment equipment; wherein, the initial control signals include at least one of the compressor frequency, the ratio of the output power to the rated power, and the target evaporation temperature of the HVAC equipment.

[0052] In an example, the initial control signals of each HVAC equipment corresponding to the allocation information can be obtained in any one of the ways such as the default settings at the time of factory, user settings, energy efficiency standards, etc. For example, if the allocation information includes taking the A air conditioner unit as the dehumidification equipment, then the default operating frequency, the preset output power ratio, and the target evaporation temperature, etc. corresponding to the air conditioner unit under the current environmental data (temperature and humidity) can be obtained according to the factory default settings. Similarly, it can also be set by the user when installing or using the air conditioner according to personal preferences or specific requirements, including the set operating frequency, the set output power ratio, and the set target evaporation temperature, etc. corresponding to the air conditioner unit under the current environmental data (temperature and humidity). The initial control signals are obtained according to the energy efficiency standards, which can be for meeting specific energy efficiency standards or certifications. When the air conditioner unit is designed, it will be set to operate under specific energy efficiency parameters, and parameters such as the standard operating frequency, the standard output power ratio, and the standard target evaporation temperature, etc. corresponding to the air conditioner unit under the current environmental data (temperature and humidity) can be used as part of the initial control signals.

[0053] It can be understood that for different types of HVAC equipment, the corresponding control signals are also different. For example, for the dehumidification equipment, its compressor frequency is 30 Hz, the ratio of the output power to the rated power is 50%, and the target evaporation temperature is 3°C. To enhance the dehumidification effect, the target evaporation temperature of the dehumidification equipment in this embodiment preferably can be in the range of 2°C to 6°C.

[0054] For the sensible heat treatment equipment, its compressor frequency is 35 Hz, the ratio of the output power to the rated power is 70%, and the target evaporation temperature is 14°C. To meet the requirements of sensible heat treatment, the target evaporation temperature of the sensible heat treatment equipment in this embodiment preferably can be in the range of 12°C to 16°C.

[0055] In this embodiment, by directly using the initial control signal as the control signal for each HVAC device during the dehumidification process, the HVAC device can quickly operate according to the initial control signal, reducing the control signal process and enabling the environmental parameters to quickly approach the user's requirements.

[0056] In the embodiment of the present application, determining the control signal of each HVAC device according to the allocation information further includes: obtaining the actual environmental parameters in the target space, and adjusting the allocation information and / or the control signal of the HVAC device according to the actual environmental parameters.

[0057] Among them, adjusting the allocation information can change the number of dehumidification devices or the number of sensible heat treatment devices. Adjusting the control signal of the HVAC device may include adjusting the compressor frequency, changing the output power ratio, setting a new target evaporation temperature, etc.

[0058] In this embodiment, by obtaining the actual environmental parameters in the target space and then adjusting the allocation information and / or the control signal of the HVAC device according to the actual environmental parameters, the dynamic adjustment of the allocation information and / or the control signal of the HVAC device can be based on the actual environmental parameters. With this dynamic adjustment mechanism, the HVAC system can respond more flexibly to environmental changes, achieve more precise environmental control, and improve energy efficiency at the same time.

[0059] In the embodiment of the present application, the allocation information includes classifying HVAC devices into dehumidification devices, and the actual environmental parameters include air humidity. Adjusting the allocation information according to the actual environmental parameters includes: increasing the ratio of the number of dehumidification devices to the total number of HVAC devices according to the air humidity being greater than the first preset humidity and the duration of the air humidity being greater than the first preset humidity being greater than the first time; decreasing the ratio of the number of dehumidification devices to the total number of HVAC devices according to the air humidity being less than the second preset humidity; the second preset humidity is less than the first preset humidity.

[0060] Continuing the above example, there are 5 air conditioning unit machines in the conference room, and these devices are all in the cooling state. The control target is to control the indoor humidity within a comfortable range. The preset humidity control parameters include: the first preset humidity (65%), the second preset humidity (50%), and the first time (15 minutes). If the actual environmental parameter is that the actual air humidity in the conference room is 70% and it has lasted for more than 15 minutes, then the actual air humidity (70%) is greater than the first preset humidity (65%). According to the allocation information adjustment rule, it is necessary to increase the ratio of the number of dehumidification devices to the total number of HVAC devices. Assuming that there was originally 1 dehumidification device and now it needs to be increased, one of the air conditioning unit machines originally used as a sensible heat treatment device is reallocated as a dehumidification device, and now there are a total of 2 dehumidification devices.

[0061] If the actual environmental parameter is that the actual air humidity in the meeting room is 45%, then the actual air humidity (45%) is less than the second preset humidity (50%). According to the allocation information adjustment rule, it is necessary to reduce the ratio of the total number of dehumidification equipment to HVAC equipment. Suppose there were originally 2 dehumidification equipment, and now it is necessary to reduce. One of the air conditioner unit machines originally used as dehumidification equipment is reallocated as heat treatment equipment. Now there is a total of 1 dehumidification equipment.

[0062] It can be seen from this that this embodiment can dynamically adjust the allocation information of HVAC equipment according to actual environmental parameters to achieve more precise environmental control and energy efficiency optimization.

[0063] In the embodiment of the present application, the allocation information includes classifying HVAC equipment into dehumidification equipment, and the actual environmental parameters include air humidity. Adjusting the control signal according to the actual environmental parameters includes: reducing the target evaporation temperature of the dehumidification equipment according to the air humidity being greater than the first preset humidity and the duration of the air humidity being greater than the first preset humidity being greater than the first time; increasing the target evaporation temperature of the dehumidification equipment according to the air humidity being less than the second preset humidity; the second preset humidity is less than the first preset humidity.

[0064] Continuing the above example, there are 5 air conditioner unit machines in the meeting room, and these devices are all in the refrigeration state. The control goal is to control the indoor humidity within a comfortable range. The preset humidity control parameters include: the first preset humidity (65%), the second preset humidity (50%), and the first time (15 minutes). If the actual environmental parameter is that the actual air humidity in the meeting room is 70% and it has lasted for more than 15 minutes, then the actual air humidity (70%) is greater than the first preset humidity (65%). According to the allocation information adjustment rule, it is necessary to reduce the target evaporation temperature of the dehumidification equipment to make the evaporator surface colder, increase the amount of condensed water vapor, thereby improving the dehumidification effect, removing more moisture from the indoor air, and reducing the air humidity.

[0065] If the actual environmental parameter is that the actual air humidity in the meeting room is 45%, then the actual air humidity (45%) is less than the second preset humidity (50%). According to the allocation information adjustment rule, it is necessary to increase the target evaporation temperature of the dehumidification equipment to reduce the dehumidification intensity and prevent the indoor environment from being too dry due to excessive dehumidification.

[0066] The above embodiment can dynamically adjust the control signal of HVAC equipment according to the actual environmental humidity to achieve more precise environmental control and energy efficiency optimization, and can be applicable to the scenario where when the number of HVAC equipment is limited, it is not possible to moderately control by adjusting the number of dehumidification equipment, further improving the applicable scenario of the present application.

[0067] In the above embodiments, when receiving an energy-saving control instruction, multiple sets of HVAC devices can be made to be in an energy-saving mode as a whole, and multiple sets of HVAC equipment in the same space can be controlled collaboratively. By dividing multiple sets of HVAC equipment into dehumidification equipment and sensible heat treatment equipment, the dehumidification equipment is used to reduce the humidity in the target space, and the sensible heat treatment equipment is used to reduce the temperature in the target space, so that targeted energy efficiency management can be carried out to achieve energy saving and more precise control of humidity and temperature. And based on the actual environmental parameters, the distribution information and / or the HVAC equipment control signal can be dynamically adjusted. With this dynamic adjustment mechanism, the HVAC system can respond more flexibly to environmental changes, achieve more precise environmental control, improve energy efficiency while achieving more refined environmental control, and improve the user's comfort and meet specific environmental requirements.

[0068] Based on the HVAC equipment collaborative control method provided in the above embodiments, the preset condition is used to represent the constraint conditions for multiple sets of HVAC equipment to operate collaboratively. Then when the constraint condition is receiving a constant temperature and dehumidification control instruction sent by the user, in the embodiments of the present application, according to the HVAC equipment meeting the preset condition, the distribution information is determined, and it further includes: according to the received constant temperature and dehumidification control instruction, determining that the distribution information includes dividing multiple sets of HVAC equipment into refrigeration equipment and heating equipment; wherein, the number of heating equipment is greater than or equal to 1 and the ratio of the number of heating equipment to the total number of HVAC equipment is less than a second preset ratio.

[0069] Among them, the constant temperature and dehumidification control instruction is to achieve the purpose of dehumidification without changing the environmental temperature. Then in this embodiment, when the electronic device receives the constant temperature and dehumidification control instruction, it indicates that the electronic device needs to determine new distribution information to maintain the indoor temperature constant and control the humidity at the same time. Then at this time, determining the distribution information includes dividing multiple sets of HVAC equipment into refrigeration equipment and heating equipment. Among them, the refrigeration equipment will reduce the air temperature during the refrigeration process, causing the water vapor in the air to condense into water droplets and thus be discharged outdoors, which can achieve the effect of dehumidification. The heating equipment can also adjust the environmental temperature. Therefore, by reasonably distributing the refrigeration equipment and the heating equipment, the system can effectively control the humidity while keeping the indoor temperature constant, and at the same time reduce energy consumption.

[0070] Among them, the number of heating equipment being greater than or equal to 1 can make at least one set of air conditioning equipment in the target space be used to adjust the temperature to achieve the purpose of constant temperature. The ratio of the number of heating equipment to the total number of HVAC equipment being less than the second preset ratio can also control the number of heating equipment within a certain range to optimize energy efficiency and avoid overheating.

[0071] In an example, the user can set the second preset ratio according to personal comfort and energy-saving goals. Preferably, the second preset ratio is less than or equal to 30%.

[0072] On the one hand, this embodiment can allocate multiple sets of HVAC equipment, enabling the coordinated operation of multiple sets of HVAC equipment in the same target space, so that the HVAC equipment no longer operates independently, optimizing the overall operation efficiency and reducing the increase in energy consumption caused by separate control of the HVAC equipment. On the other hand, by dividing multiple sets of HVAC equipment into refrigeration equipment and heating equipment, and through reasonable allocation of the refrigeration equipment and heating equipment, the system can effectively control the humidity while maintaining a constant indoor temperature, achieving constant temperature and dehumidification.

[0073] In the embodiment of the present application, the allocation information includes the number of refrigeration equipment and the number of heating equipment. According to the allocation information, the control signals of each HVAC equipment are determined, including: obtaining the actual environmental parameters in the target space, and the actual environmental parameters include the environmental temperature; according to the environmental temperature, the number of refrigeration equipment, the number of heating equipment, and the preset cooling and heating energy ratio, the target evaporation temperature of the refrigeration equipment and the target condensation temperature of the heating equipment are obtained, and are used as the control signals of the refrigeration equipment and the heating equipment respectively.

[0074] In this embodiment, the preset cooling and heating energy ratio characterizes the energy output ratio of the HVAC equipment in the cooling and heating modes. In this embodiment, it is the energy output ratio of the refrigeration equipment to the heating equipment. By calculating the target evaporation temperature of the refrigeration equipment and the target condensation temperature of the heating equipment through the environmental temperature, the number of refrigeration equipment, the number of heating equipment, and the preset cooling and heating energy ratio, the energy balance between the refrigeration equipment and the heating equipment can be achieved, enabling the overall HVAC device to operate efficiently in the constant temperature and dehumidification mode.

[0075] In this embodiment, the target evaporation temperature (Tes) can be obtained from the coil temperature on the indoor unit heat exchanger, or can be obtained from the pressure sensor set between the compressor suction port and the low-pressure cut-off valve. The target evaporation temperature directly affects the refrigeration effect and the energy consumption level. Therefore, by calculating the target evaporation temperature of the refrigeration equipment as the control signal of the refrigeration equipment, the situation of excessive energy consumption can be reduced while achieving the refrigeration effect.

[0076] The target condensation temperature (Tcs) can be obtained from the coil temperature on the outdoor unit heat exchanger, or can be obtained from the pressure sensor set between the compressor discharge port and the inlet of the outdoor unit heat exchanger. It determines the performance and efficiency of the heating equipment. Therefore, by calculating the target condensation temperature of the heating equipment as the control signal of the heating equipment, the situation of excessive energy consumption can be reduced while achieving the heating effect.

[0077] Of course, in some examples, the control signal can also be control parameters such as the compressor frequency, the energy output ratio of each HVAC device, and the fan speed.

[0078] In this embodiment, the target evaporation temperature of the refrigeration equipment and the target condensation temperature of the heating equipment are obtained based on the ambient temperature, the number of refrigeration equipment, the number of heating equipment, and the preset cooling-heating energy ratio as control signals, which can improve the control accuracy of coordinated control, enabling the air conditioning system to optimize energy efficiency while meeting the indoor environment control requirements.

[0079] In the embodiment of the present application, obtaining the target evaporation temperature of the refrigeration equipment and the target condensation temperature of the heating equipment according to the ambient temperature, the number of refrigeration equipment, the number of heating equipment, and the preset cooling-heating energy ratio includes: obtaining the refrigeration capacity parameter of the refrigeration equipment and the heating capacity parameter of the heating equipment; determining the total refrigeration parameter of the refrigeration equipment according to the number of refrigeration equipment and the refrigeration capacity parameter; determining the total heating parameter of the heating equipment according to the number of heating equipment and the heating capacity parameter; and obtaining the target evaporation temperature of the refrigeration equipment and the target condensation temperature of the heating equipment according to the ambient temperature, the total refrigeration parameter of the refrigeration equipment, the total heating parameter of the heating equipment, and the preset cooling-heating energy ratio.

[0080] Among them, the preset cooling-heating energy ratio is greater than 1 and less than 3, which can achieve the energy balance between the refrigeration equipment and the heating equipment, enabling the overall HVAC device to operate efficiently in the constant temperature and dehumidification mode.

[0081] In this embodiment, the refrigeration capacity parameter of the refrigeration equipment and the heating capacity parameter of the heating equipment are parameters characterizing the refrigeration or heating capacity of the air conditioning unit. For example, the horsepower of the air conditioning unit, where "horsepower (HP)" is used to characterize the refrigeration or heating capacity of the air conditioning unit. 1 HP is approximately equal to 2500 watts of refrigeration capacity. The higher the horsepower, the greater the refrigeration or heating capacity of the air conditioning unit.

[0082] Determining the total refrigeration parameter of the refrigeration equipment according to the number of refrigeration equipment and the refrigeration capacity parameter. For example, if the number of refrigeration equipment is 3 and the refrigeration capacity parameter of each refrigeration equipment is 2 HP, then the total refrigeration parameter of the refrigeration equipment is 6 HP. Similarly, for example, if the number of heating equipment is 2 and the heating capacity parameter of each heating equipment is 1.5 HP, then the total refrigeration parameter of the heating equipment is 3 HP.

[0083] In an example, the target evaporation temperature Tes and the target condensation temperature Tcs can be calculated using the following formula 1. Formula 1:

[0084] (T1 - Tes) * total refrigeration parameter of the refrigeration equipment = M * (Tcs - T1) * total heating parameter of the heating equipment

[0085] Among them, T1 is the ambient temperature, M is the preset cooling and heating energy (1 < M < 3, preferably 2), Tes is the target evaporation temperature, and Tcs is the target condensation temperature.

[0086] Then, the target evaporation temperature Tes and the target condensation temperature Tcs are calculated through the above formula 1, and then sent to the refrigeration equipment and the heating equipment as control signals respectively.

[0087] The above embodiments obtain the target evaporation temperature of the refrigeration equipment and the target condensation temperature of the heating equipment through the actual ambient temperature, the total refrigeration parameters of the refrigeration equipment, the total heating parameters of the heating equipment, and the preset cooling and heating energy ratio to determine the control signals of the HVAC equipment, so as to achieve more precise environmental control and energy efficiency optimization, and achieve energy balance between the refrigeration and heating equipment, enabling the system to operate efficiently in the constant temperature and dehumidification mode.

[0088] In the embodiments of the present application, after controlling each HVAC equipment to perform corresponding actions according to the control signals, the method further includes: obtaining the operation duration of each HVAC equipment, switching the refrigeration equipment with the longest operation duration to heating equipment, and switching the heating equipment with the longest operation duration to refrigeration equipment.

[0089] As shown above, after sending the target evaporation temperature to the refrigeration equipment and the target condensation temperature to the heating equipment, each HVAC equipment performs corresponding actions according to the received control signals. In order to reduce the equipment from maintaining the same operation mode for a long time and improve the operation life of the HVAC equipment, this embodiment obtains the operation duration of each HVAC equipment. By comparing the operation durations of all equipment, the electronic device identifies the refrigeration equipment and the heating equipment with the longest operation duration, switches the refrigeration equipment with the longest operation duration to heating equipment, and switches the heating equipment with the longest operation duration to refrigeration equipment. At the same time, it can be understood that when the mode of the HVAC equipment changes, its corresponding control signal will also change. After switching the type of the HVAC equipment, the electronic device will send a new control signal to the corresponding equipment to adapt to the new operation mode.

[0090] The above embodiments balance the operation time of the equipment by switching the types of the HVAC equipment. Dynamically adjusting the equipment mode can enable each HVAC equipment to operate in the best energy efficiency state and reduce energy waste.

[0091] In the embodiments of the present application, the HVAC equipment includes an indoor unit and an outdoor unit, and the method further includes: obtaining the identification information of the outdoor unit corresponding to each indoor unit; using at least one indoor unit with the same identification information and the outdoor unit corresponding to the identification information as a set of HVAC equipment.

[0092] The identification information of the outdoor unit in this embodiment can be the number or identification code of the outdoor unit. By taking at least one indoor unit with the same identification information and the outdoor unit corresponding to the identification information as a set of HVAC equipment, it can be applicable to the scenario where one outdoor unit is connected to multiple indoor units, improving the applicable scenarios of the embodiments of this application.

[0093] In the above embodiment, when receiving the constant temperature and dehumidification control instruction, it can make multiple sets of HVAC devices be in the constant temperature and dehumidification mode as a whole, and perform collaborative control on multiple sets of HVAC equipment in the same space. By dividing multiple sets of HVAC equipment into refrigeration equipment and heating equipment, the refrigeration equipment can achieve the effect of dehumidification during the refrigeration process. The heating equipment can also regulate the ambient temperature. Therefore, by reasonably allocating the refrigeration equipment and the heating equipment, the system can effectively control the humidity while keeping the indoor temperature constant, and at the same time reduce energy consumption. And by using the actual ambient temperature, the total refrigeration parameters of the refrigeration equipment, the total heating parameters of the heating equipment, and the preset cooling and heating energy ratio, the target evaporation temperature of the refrigeration equipment and the target condensation temperature of the heating equipment are obtained to determine the control signal of the HVAC equipment, so as to achieve more precise environmental control and energy efficiency optimization, and achieve the energy balance between the refrigeration and heating equipment, enabling the system to operate efficiently in the constant temperature and dehumidification mode.
