Technical Field

[0001] This invention relates to the field of air conditioning technology, and more particularly to a control method for an air conditioner, an air conditioner, and a computer-readable storage medium. Background Technology

[0002] With the development of economy and technology, the application of air conditioners is becoming more and more widespread. Air conditioners use an indoor heat exchanger in a heat pump cycle to exchange heat with the air, and then send the heat-exchanged air into the indoor environment through a fan to regulate the indoor air temperature.

[0003] During the heating process of an air conditioner, the air conditioner generally regulates the air solely through the heat pump circulation. Its regulation capability is limited.

[0036] Optionally, the water circulation system further includes a circulating water pump and an indoor fan corresponding to the indoor heat exchanger. The circulating water pump is located in the connecting pipe between the indoor heat exchanger and the outdoor heat exchanger. The step of controlling the shutdown of the refrigerant circulation system and the water circulation system includes:

[0038] When the refrigerant circulation system has been shut down for a set period of time, the circulating water pump is controlled to shut down.

[0047] The control device is connected to the refrigerant circulation system, the water circulation system, and the heating module. The control device includes a memory, a processor, and an air conditioner control program stored in the memory and executable on the processor. When the air conditioner control program is executed by the processor, it implements the steps of the air conditioner control method as described above.

[0048] In addition, to achieve the above objectives, this application also proposes a computer-readable storage medium storing a control program for an air conditioner, which, when executed by a processor, implements the steps of the control method for the air conditioner as described in any of the preceding claims.

[0049] This invention proposes a control method for an air conditioner, based on an air conditioner including a refrigerant circulation system, a water circulation system, and a heating module. When the air conditioner is operating in heating mode, the refrigerant circulation system operates in heating mode and the water circulation system is activated. The refrigerant circulation system heats the water in the outdoor heat exchanger of the water circulation system. The heated water circulates between the indoor and outdoor heat exchangers. After flowing to the indoor heat exchanger, the heated water can raise the indoor air temperature through heat exchange. During this process, the heating module is simultaneously activated to heat the indoor air or supplement the heat needed by the human body. Adding a heating module to the air conditioner helps to compensate for the insufficient adjustment capacity of the heat pump module formed by the refrigerant circulation system and the water circulation system. Through the coordinated operation of the heating module, the refrigerant circulation system, and the water circulation system, the heating efficiency of the air conditioner during heating is effectively improved. Furthermore, the medium used for circulating heat exchange on the indoor side of the air conditioner is no longer the flammable refrigerant at high temperatures, but water. This ensures that the indoor side will not experience safety accidents due to excessively high temperatures during the air conditioner's heating cycle, thus improving the heating efficiency of the air conditioner while ensuring safe operation and enhancing the comfort of indoor users during heating operation.

[0057] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0058] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0059] The main solution of this invention is as follows: the air conditioner includes a refrigerant circulation system, a water circulation system, and a heating module. The water circulation system includes an indoor heat exchanger and an outdoor heat exchanger. The outdoor heat exchanger is connected to the refrigerant circulation system for heat exchange. The control method of the air conditioner includes the following steps: obtaining the operating mode of the air conditioner; when the operating mode is heating mode, controlling the refrigerant circulation system to operate in heating mode, controlling the water circulation system to start, and controlling the heating module to start; wherein, when the refrigerant circulation system is operating in heating mode, it heats the water in the outdoor heat exchanger; when the water circulation system is started, the water circulates between the indoor heat exchanger and the outdoor heat exchanger; and when the heating module is started, it heats the indoor air or supplements the heat required by the human body.

[0060] In the current technology, during the heating process of an air conditioner, the air conditioner generally regulates the air solely through a heat pump circulation. Its regulation capability is limited. When the operating conditions are poor or the user has restrictions on the wind feel and noise, the heating efficiency is prone to be poor, the indoor temperature rises too slowly, and the comfort of the indoor users is affected.

[0061] The present invention provides the above-mentioned solution, which aims to improve the heating efficiency of the air conditioner while ensuring its safe operation, so as to improve the comfort of indoor users when the air conditioner is heating.

[0062] This invention provides an air conditioner. In this embodiment, the air conditioner is a wall-mounted air conditioner. In other embodiments, the air conditioner may also be a floor-standing air conditioner, a window air conditioner, a portable air conditioner, etc.

[0063] In this embodiment of the invention, reference is made to Figure 1 The air conditioner includes a heating module 1. The heating module 1 is used to heat indoor air or supplement the body with heat. In this embodiment, the heating module 1 is a radiation module, such as an infrared heating module 1, which heats indoor air or supplements the body with heat by emitting infrared rays.

[0064] The air conditioner may also include a housing 2 and a heat pump module 3, which is used to regulate air temperature through heat exchange. The heat pump module 3 includes an indoor heat exchanger 31 and an indoor fan 32 corresponding to the indoor heat exchanger 31. The housing 2 is provided with a return air inlet 21 and an air outlet 22, and the housing 2 is provided with an air duct connecting the return air inlet 21 and the air outlet 22. The indoor heat exchanger 31 and the indoor fan 32 are located in the air duct. The indoor fan 32 can drive indoor air to enter the air duct from the return air inlet 21. Liquid carrying heat or cold can enter the indoor heat exchanger 31 to exchange heat with the indoor air in the air duct. The heat-exchanged indoor air can be sent into the room through the air outlet 22.

[0065] The number of air outlets 22 can be set according to actual needs, and can be one, two or more.

[0066] The heating module 1 can be located on the outer wall of the housing 2 or as part of the housing 2, or it can be located inside the air duct. When the heating module 1 is located on the outer wall of the housing 2 or as part of the housing 2, the heating module 1 can directly heat the air in the indoor environment. When the heating module 1 is located inside the air duct, it can cooperate with the indoor heat exchanger 31 to heat the indoor air entering the air duct, and the heated air is sent into the indoor environment from the air outlet 22.

[0067] Specifically, the heating module 1 can be provided with multiple vents to allow air to flow through different locations on the heating module 1, increasing the heat dissipation area of ​​the heating module 1 and improving its heating efficiency. In addition, the vents on the heating module 1 can be used as return air inlets 21 to heat the return air; or, they can be used as outlet air inlets 22 to heat the outlet air. The heating module 1 can also be equipped with valves to open or close the aforementioned multiple vents.

[0068] The air outlet 22 may be equipped with an air guide, which can be used to regulate the air outlet direction and / or the air volume passing through the air outlet 22. When there is more than one air outlet 22, each air outlet 22 may be equipped with an air guide 4 to achieve independent regulation of the air outlet direction and / or the air volume passing through each air outlet 22.

[0069] In one embodiment of the air conditioner, such as Figure 1 As shown in (a), the heating module 1 is fixedly installed on the outside of the housing 2. The air entering the air duct from the return air inlet 21 is heat-exchanged by the indoor heat exchanger 31 and then sent into the indoor environment from the air outlet 22. In addition, the heating module 1 installed on the outside of the housing 2 releases radiation waves to directly heat the air near the housing 2.

[0070] In another embodiment of the air conditioner, such as Figure 1 As shown in (b), the heating module 1 is located inside the air duct, and multiple vents can serve as return air vents 21 for the air conditioner. Driven by the indoor fan 32, indoor air can enter the air duct through the multiple vents of the heating module 1. The heating module 1 can heat the air entering the air duct. The heated air can be further heated by the indoor heat exchanger 31, and the heated air is sent into the indoor environment from the air outlet 22.

[0071] In another embodiment of the air conditioner, such as Figure 1As shown in (c), the heating module 1 is movably mounted on the housing 2. Specifically, the heating module 1 can be mounted on the housing 2 via a rotating shaft. The heating module 1 has a first state and a second state. In this embodiment, the heating module 1 is specifically a radiation module. In the first state, the radiation module 1 is attached to the outer surface of the housing 2; in the second state, the radiation module 1 rotates away from the housing 2 so that the radiating surface faces the front of the housing 2. In this embodiment, the radiation module 1 can rotate relative to the housing 2 between the first and second states. In the first state, the radiation module 1 is not working and is moved to be attached to the outer surface of the housing 2, ensuring the compactness of the overall appearance and reducing the exposed area and dust adhesion. In the second state, the radiation module 1 is turned on, and the radiating surface radiates heat to the outside. At this time, the radiation module 1 is rotated away from the outer surface of the housing 2 so that the radiating surface faces the front of the housing 2, thereby realizing rapid radiative heating of the air in the front space area of ​​the housing 2. Understandably, in the second state, radiation module 1 can be fixed in a certain position or rotated and adjusted within a certain area to further expand the range of heat radiation from the radiating surface.

[0072] The angle of rotation of the radiation module 1 relative to the outer surface of the housing 2 is defined as α, which satisfies α∈[0°, 100°].

[0073] Understandably, in the first state, the angle between the radiation module 1 and the outer surface of the housing 2 is 0°; in the second state, the radiation module 1 can rotate outward relative to the outer surface of the housing 2 to a preset position, wherein the preset position is within the range of angle α, and can be arbitrarily adjusted within α, so that the radiation surface can be fixed at a certain position within [0°, 100°] to radiate heat into the room, or the radiation position can be arbitrarily adjusted within the range of [0°, 100°] to expand the heat radiation range. Optionally, the rotation angle of the radiation module 1 relative to the outer surface of the housing 2 cannot be too large, otherwise it may cause the radiation surface to move too far and face the top or back of the housing 2, resulting in poor heat radiation effect.

[0074] In this embodiment, refer to Figure 2The heat pump module 3 may include a refrigerant circulation system 301 and a water circulation system 302. The water circulation system 302 includes the aforementioned indoor heat exchanger 31 and an outdoor heat exchanger, with the outdoor heat exchanger located in the outdoor environment. The refrigerant circulation system 301 is connected to the outdoor heat exchanger for heat exchange. The pipes in the water circulation system 302 are filled with liquid water, while the pipes in the refrigerant circulation system 301 are filled with a refrigerant such as a fluoride (e.g., Freon). When the refrigerant circulation system 301 is activated, the refrigerant circulates and exchanges heat with the water in the outdoor heat exchanger to regulate the temperature of the water circulating in the water circulation system 302. When the water circulation system 302 is activated, water circulates between the indoor heat exchanger 31 and the outdoor heat exchanger. After exchanging heat with the refrigerant circulation system 301, the water enters the indoor heat exchanger 31 and exchanges heat with the air in the duct to regulate the temperature of the air in the duct. It should be noted that the heat exchange connection between the refrigerant circulation system 301 and the outdoor heat exchanger is a non-mass transfer heat exchange connection, which means that the water and refrigerant circulate independently and transfer heat to each other without mixing.

[0075] The water circulation system 302 may also include a circulating water pump, which is located in the connecting pipe between the indoor heat exchanger and the outdoor heat exchanger. When the circulating water pump is turned on, it can drive liquid water to circulate between the indoor heat exchanger and the outdoor heat exchanger.

[0076] In this embodiment, the outdoor heat exchanger in the refrigerant circulation system 301 and the water circulation system 302 are connected in the heat exchange device 01 for heat exchange.

[0077] Specifically, the refrigerant circulation system 301 includes a compressor, a first heat exchanger, a throttling device, and a second heat exchanger connected in sequence via pipelines, wherein the first heat exchanger is connected to the outdoor heat exchanger for heat exchange. When the compressor is turned on, the refrigerant circulates between the compressor, the first heat exchanger, the throttling device, and the second heat exchanger. The refrigerant flowing through the first heat exchanger can exchange heat with the water in the outdoor heat exchanger in the water circulation system 302 to regulate the temperature of the circulating water in the water circulation system 302.

[0078] Furthermore, the refrigerant circulation system 301 may also include a four-way valve to enable the air conditioner to switch between cooling and heating modes. Specifically, the compressor's discharge port, compressor's return port, one end of the first heat exchanger, and one end of the second heat exchanger are respectively connected to the four ports of the four-way valve. The four-way valve has different valve positions, and different valve positions correspond to different heat exchange modes of the air conditioner. When the four-way valve is in the first valve position, the air conditioner is in heating mode. The refrigerant from the compressor discharge port passes through the first heat exchanger, the throttling device, and the second heat exchanger in sequence, and then flows back to the compressor from the compressor's return port. The first heat exchanger is in a condensing state. The first heat exchanger exchanges heat with the water in the outdoor heat exchanger in the water circulation system 302 to increase the temperature of the circulating water in the water circulation system 302. The high-temperature water exchanges heat with the air in the air duct to increase the air temperature. When the four-way valve is in the second position, the air conditioner is in cooling mode. The refrigerant from the compressor discharge port passes through the second heat exchanger, the throttling device and the first heat exchanger in sequence, and then flows back to the compressor from the compressor return port. The first heat exchanger is in the evaporation state. The first heat exchanger exchanges heat with the water in the outdoor heat exchanger in the water circulation system 302 to reduce the temperature of the circulating water in the water circulation system 302. The low-temperature water exchanges heat with the air in the air duct to reduce the temperature of the air.

[0079] Furthermore, the air conditioner may also include a temperature detection module 5, which is used to detect relevant characteristic temperatures during the operation of the heating module 1. In this embodiment, the temperature detection module 5 includes a first temperature sensor, a second temperature sensor, and a third temperature sensor. Specifically, the first temperature sensor is disposed on the surface of the heating module 1 to detect the temperature of the heating module 1. The second temperature sensor is disposed on the indoor heat exchanger 31 to detect the temperature of the indoor heat exchanger 31. The third temperature sensor is disposed in the indoor environment or on the outside of the casing 2 to detect the indoor ambient temperature.

[0080] Furthermore, the air conditioner may also include a water temperature sensor 6, which may be located in the indoor heat exchanger to detect the water temperature of the indoor heat exchanger.

[0081] Furthermore, the air conditioner may also include a water inlet pipe, which connects the water circulation system to a hot water device (such as a gas water heater, solar water heater, heat pump water heater, or electric water heater) outside the air conditioner. A first hot water pump 7 may be installed on the water inlet pipe, which, when turned on, can supply hot water to the water circulation system.

[0082] Furthermore, the air conditioner may also include a water outlet pipe, which connects the water circulation system to a water-using device outside the air conditioner (such as a gas water heater, solar water heater, heat pump water heater, electric water heater, cleaning device, and / or hot water intake device). A second hot water pump 8 may be installed on the water outlet pipe. When the second hot water pump 8 is turned on, it sends part of the hot water in the water circulation system to the water-using device, while the other part of the hot water circulates between the indoor heat exchanger 31 and the outdoor heat exchanger.

[0083] Furthermore, refer to Figure 3 The air conditioner may also include a control device, and the aforementioned heating module 1, heat pump module 3, temperature detection module 5, water temperature sensor 6, first hot water pump 7, and second hot water pump 8 are all connected to this control device. The control device can be used to control the operation of the heating module 1, heat pump module 3, first hot water pump 7, and second hot water pump 8, and can also be used to acquire temperature detection data from the temperature detection module 5 and water temperature sensor 6.

[0084] In this embodiment of the invention, reference is made to Figure 2 The control device may include a processor 1001 (e.g., CPU), a memory 1002, etc. The processor 1001 and the memory 1002 are connected via a communication bus. The memory 1002 may be a high-speed RAM or a stable memory (non-volatile memory), such as a disk storage device. Optionally, the memory 1002 may also be a storage device independent of the aforementioned processor 1001.

[0085] Those skilled in the art will understand that Figure 3 The device structure shown does not constitute a limitation on the device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0086] like Figure 3 As shown, the memory 1002, which is a computer-readable storage medium, may include a control program for an air conditioner. Figure 3 In the device shown, the processor 1001 can be used to call the control program of the air conditioner stored in the memory 1002 and execute the relevant steps of the control method of the air conditioner in the following embodiments.

[0087] This invention also provides a control method for an air conditioner, which is used to control the operation of the air conditioner.

[0088] Reference Figure 4This application proposes an embodiment of a control method for an air conditioner. In this embodiment, the air conditioner includes a refrigerant circulation system, a water circulation system, and a heating module. The water circulation system includes an indoor heat exchanger and an outdoor heat exchanger, with the outdoor heat exchanger connected to the refrigerant circulation system for heat exchange. The control method for the air conditioner includes:

[0089] Step S10: Obtain the operating mode of the air conditioner;

[0090] Air conditioners can be divided into different operating modes based on different target air conditioning needs. In this embodiment, the air conditioner's operating modes are divided into cooling mode and heating mode.

[0091] Specifically, the operating mode of an air conditioner can be determined by obtaining user input commands, or by monitoring indoor scene data and determining the current operating mode of the air conditioner based on the monitored indoor scene data.

[0092] Step S20: When the operating mode is heating mode, control the refrigerant circulation system to operate in heating mode, control the water circulation system to start, and control the heating module to start; wherein, when the water circulation system is started, water circulates between the indoor heat exchanger and the outdoor heat exchanger, the refrigerant circulation system heats the water in the outdoor heat exchanger when it is operating in heating mode, and the heating module heats the indoor air or supplements the heat required by the human body when it is started.

[0093] In heating mode, the refrigerant circulation system operates in heating mode, controlling the compressor in the refrigerant circulation system to start and the four-way valve to operate in the first position. The high-temperature refrigerant flowing out of the compressor flows into the first heat exchanger. The first heat exchanger is in a condensing state and releases heat. The first heat exchanger exchanges heat with the water in the outdoor heat exchanger in the water circulation system to heat the water in the outdoor heat exchanger in the water circulation system. The heated water flows to the indoor heat exchanger to heat the air in the air duct. The water that has exchanged heat in the indoor heat exchanger flows back to the outdoor heat exchanger for reheating, and so on in a continuous cycle.

[0094] Controlling the water circulation system specifically includes controlling the activation of the circulating water pump in the water circulation system. When the circulating water pump is activated, it can operate at a preset fixed power or at a power determined based on the actual operating conditions of the air conditioner (such as the outlet air temperature, indoor ambient temperature, and / or the radiant temperature of the heating module).

[0095] Specifically, when the heating module is located in the housing, it can directly heat the indoor air or supplement the heat required by the human body when it is turned on; when the heating module is located in the air duct and on the return air side of the air conditioner, it heats the air on the air inlet side of the indoor heat exchanger when it is turned on.

[0096] When the heating module is turned on, it can operate according to the preset heating parameters, or it can operate according to the heating parameters determined by the actual operating conditions of the air conditioner (such as the outlet air temperature, indoor ambient temperature, duration of heating operation, water temperature of the indoor heat exchanger and / or surface temperature of the heating module).

[0097] The refrigerant circulation system, water circulation system, and heating module can be turned on simultaneously, or the refrigerant circulation system and water circulation system can be turned on first, and the heating module can be turned on when the air conditioner reaches the set operating conditions.

[0098] This invention proposes a control method for an air conditioner, based on an air conditioner including a refrigerant circulation system, a water circulation system, and a heating module. When the air conditioner is operating in heating mode, the refrigerant circulation system operates in heating mode and the water circulation system is activated. The refrigerant circulation system heats the water in the outdoor heat exchanger of the water circulation system. The heated water circulates between the indoor and outdoor heat exchangers. After flowing to the indoor heat exchanger, the heated water can raise the indoor air temperature through heat exchange. During this process, the heating module is simultaneously activated to heat the indoor air or supplement the heat needed by the human body. Adding a heating module to the air conditioner helps to compensate for the insufficient adjustment capacity of the heat pump module formed by the refrigerant circulation system and the water circulation system. Through the coordinated operation of the heating module, the refrigerant circulation system, and the water circulation system, the heating efficiency of the air conditioner during heating is effectively improved. Furthermore, the medium used for circulating heat exchange on the indoor side of the air conditioner is no longer the flammable refrigerant at high temperatures, but water. This ensures that the indoor side will not experience safety accidents due to excessively high temperatures during the air conditioner's heating cycle, thus improving the heating efficiency of the air conditioner while ensuring safe operation and enhancing the comfort of indoor users during heating operation.

[0099] Furthermore, based on the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, reference is made to... Figure 5 After step S20, the method further includes:

[0100] Step S30: During the process of the refrigerant circulation system operating in heating mode, the water circulation system and the heating module being turned on, at least one of the air outlet temperature of the air conditioner, indoor temperature parameters, outdoor ambient temperature and indoor ambient temperature rise rate is acquired.

[0101] The target air outlet temperature here is the target value that the air outlet temperature needs to reach under the current heating state of the air conditioner.

[0102] The specific air outlet temperature can be detected by a temperature sensor located at the air outlet of the air conditioner.

[0103] Indoor temperature parameters are specifically characteristic parameters that characterize the current temperature of the indoor environment. Indoor temperature parameters can be the current indoor temperature value or the rate of change of the current indoor temperature. The temperature value represents the magnitude of the current indoor temperature, while the rate of change reflects how the indoor temperature changes when the air conditioner is operating in heating mode.

[0104] The outdoor ambient temperature can be detected by a temperature sensor installed in the outdoor environment.

[0105] The heating rate can be determined by detecting the first and second temperatures of the indoor environment at set intervals during the heating process of the air conditioner. If the second temperature obtained later is greater than the first temperature obtained earlier, the difference between the second and first temperatures can be used as the heating rate. Alternatively, the ratio of the difference between the second and first temperatures to the set time interval can be used as the heating rate. The larger the difference, the greater the heating rate.

[0106] Step S40: When the preset conditions are met, control the first hot water pump of the air conditioner to turn on. When the first hot water pump is turned on, hot water from the hot water device outside the air conditioner is input into the water circulation system.

[0107] The preset conditions include at least one of the following:

[0108] The outlet air temperature is lower than the set outlet air temperature;

[0109] The indoor temperature parameter is lower than the set temperature parameter;

[0110] The outdoor ambient temperature is less than a preset temperature threshold.

[0111] The heating rate is less than the set rate.

[0112] The hot water here specifically refers to water with a temperature higher than that in the water circulation system.

[0113] When the first hot water pump is turned on, it can run at a fixed speed, or it can run at a speed determined by the compressor frequency of the refrigerant circulation system, the coil temperature of the first heat exchanger, the water temperature of the indoor heat exchanger before the first hot water pump is turned on, and / or the current water temperature of the indoor heat exchanger.

[0114] If the outlet air temperature is lower than the set outlet air temperature, it indicates that the air conditioner's current outlet air temperature is low, suggesting a demand for high-temperature airflow. Conversely, if the outlet air temperature is low (i.e., lower than the set outlet air temperature) or the outdoor ambient temperature is low (i.e., lower than the preset temperature threshold), it suggests a demand for rapid heating. Similarly, if the indoor ambient temperature is low (i.e., lower than the set temperature), the outdoor ambient temperature is low (i.e., lower than the preset temperature threshold), or the indoor ambient temperature rises slowly (i.e., slower than the set rate), it suggests a demand for rapid temperature increase. When the air conditioner has demands for high-temperature airflow, rapid heating, or rapid temperature increase, the first hot water pump is activated. Hot water mixes with the circulating water in the water circulation system to quickly raise the water temperature in the indoor heat exchanger. This significantly increases the heat provided by the indoor heat exchanger to the air, allowing the air conditioner to reach a higher outlet air temperature. This ensures safe operation of the air conditioner while further improving its heating efficiency and enhancing the thermal comfort of users in the indoor environment. The outdoor ambient temperature detection here can reduce the risk of complaints about low airflow or slow heating, so that hot water can be turned on to supplement heat in time.

[0115] Specifically, in this embodiment, after step S20, the method further includes: obtaining the surface temperature of the heating module; determining the heating power of the heating module based on the surface temperature; and controlling the heating module to operate at the heating power.

[0116] The surface temperature can be obtained by acquiring data from a temperature sensor located on the surface of the heating module. Different surface temperatures correspond to different heating powers. Specifically, when the surface temperature is lower than the preset temperature, the lower the surface temperature, the greater the heating power, thus ensuring that the heating module can provide sufficient heat to the indoor air during operation, effectively improving the heating efficiency of the air conditioner. When the surface temperature is greater than or equal to the preset temperature, the higher the surface temperature, the lower the heating power, thus preventing the heating module from overheating and being damaged, ensuring that the heating module can operate safely while improving heating efficiency.

[0117] Furthermore, based on any of the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, reference is made to... Figure 6 The water circulation system further includes an indoor fan corresponding to the indoor heat exchanger. After step S40, the system further includes:

[0118] Step S41: During the process of starting the first hot water pump, the water temperature of the indoor heat exchanger is obtained;

[0119] The specific water temperature inside the indoor heat exchanger can be obtained by acquiring data from the water temperature sensor installed on the indoor heat exchanger.

[0120] Step S42: Determine the fan control parameters and / or hot water regulation parameters based on the water temperature;

[0121] Fan control parameters are parameters used to control the operation of indoor fans. Specific fan control parameters include increasing speed, decreasing speed, maintaining speed, turning the fan on, and turning the fan off. Different fan control parameters...

[0122] Hot water control parameters are control parameters used to regulate the flow rate and / or temperature of hot water supplied by the hot water device to the water circulation system. These parameters can be control parameters for the operation of the first hot water pump or the hot water device itself. Hot water control parameters may include increasing or decreasing the output temperature of the hot water from the hot water device, and increasing or decreasing the operating speed of the first hot water pump.

[0123] Different water temperatures correspond to different fan control parameters and / or hot water regulation parameters. The correspondence between water temperature and fan control parameters and / or hot water regulation parameters (such as mapping relationships, calculation relationships, etc.) can be preset or obtained based on the current operating parameters of the heating module (e.g., the surface temperature of the heating module and / or the heating power of the heating module). Different operating parameters of the heating module correspond to different relationships between water temperature and control parameters. Based on this correspondence, the fan control parameters and / or hot water regulation parameters corresponding to the current water temperature can be determined.

[0124] In the above correspondence, the indoor fan speed corresponding to the fan control parameters increases with increasing water temperature; the hot water temperature input to the water circulation system by the hot water device corresponding to the hot water control parameters increases with decreasing water temperature; and the hot water temperature input to the water circulation system by the hot water device corresponding to the hot water control parameters increases with increasing water temperature. Conversely, the indoor fan speed corresponding to the fan control parameters decreases with decreasing water temperature; the hot water temperature input to the water circulation system by the hot water device corresponding to the hot water control parameters decreases with increasing water temperature; and the hot water temperature input to the water circulation system by the hot water device corresponding to the hot water control parameters decreases with decreasing water temperature. In other embodiments, the relationship between water temperature and the fan speed corresponding to the fan control parameters and / or the hot water temperature and water volume corresponding to the hot water control parameters may have other patterns or no clear pattern.

[0125] Step S43: Control the indoor fan to operate according to the fan control parameters, and / or control the first hot water pump and / or the hot water device to operate according to the hot water control parameters.

[0126] In this embodiment, different fan control parameters can result in different heat exchange efficiencies in the indoor heat exchanger, and different hot water control parameters can result in different amounts of heat input from the hot water device to the water circulation system. Based on this, the operation of the fan, water pump, and / or hot water device is adjusted according to the current water temperature of the indoor heat exchanger. This ensures that during the process of increasing heat through external water supply, the hot water device can provide sufficient heat for the heat exchange between the indoor heat exchanger and the air. It also ensures that the heat exchange efficiency of the indoor heat exchanger controlled by the fan can match its heat supply, ensuring that the air temperature after heat exchange and adjustment by the indoor heat exchanger is high enough, and ensuring the comfort of the air outlet during the heating process of the air conditioner.

[0127] Furthermore, in this embodiment, the step of determining the fan control parameters based on the water temperature includes:

[0128] When the water temperature is less than or equal to the first preset temperature, the fan control parameters are determined to maintain the speed of the indoor fan or reduce the speed of the indoor fan; when the water temperature is greater than the second preset temperature, the fan control parameters are determined to increase the speed of the indoor fan; the second preset temperature is greater than or equal to the first preset temperature.

[0129] The first preset temperature and the second preset temperature can be fixed temperatures set in advance, or they can be temperatures selected from multiple preset temperatures based on the current operating parameters of the heating module (e.g., the surface temperature of the heating module and / or the heating power of the heating module). In this embodiment, the second preset temperature is greater than the first preset temperature. In other embodiments, the second preset temperature may also be equal to the first preset temperature.

[0130] When the fan speed is reduced or increased, the speed adjustment parameters (such as the speed adjustment range or speed adjustment speed) can be fixed parameters that are preset, or parameters that are determined according to the actual operating conditions of the air conditioner. For example, the speed adjustment parameters when the indoor fan speed is increased or decreased can be determined according to the indoor ambient temperature, the air outlet temperature of the air conditioner, the temperature difference between the current water temperature and the target water temperature, and / or the current operating parameters of the heating module (such as the surface temperature of the heating module and / or the heating power of the heating module).

[0131] Specifically, when the water temperature is low, if the current speed of the indoor fan is less than the set speed, the indoor fan can be controlled to maintain the current speed; if the current speed of the indoor fan is greater than the set speed, the indoor fan can be controlled to reduce the current speed.

[0132] In this embodiment, when the indoor heat exchanger water temperature is low, it indicates that the heat input from the indoor heat exchanger to the air is insufficient. By maintaining or reducing the indoor fan speed, the indoor fan speed is limited to prevent further increases, thus avoiding excessively low air temperature after heat exchange through the indoor heat exchanger and preventing a large amount of low-temperature air from being blown towards the user, which helps ensure the comfort of the air conditioner's output. When the indoor heat exchanger water temperature is high, it indicates that the indoor heat exchanger has sufficient heat to exchange with the indoor air. At this time, increasing the fan speed helps improve the heat exchange efficiency of the air conditioner and the heating efficiency of the indoor environment.

[0133] Furthermore, in this embodiment, the hot water control parameters include a first operating parameter of the first hot water pump and a second operating parameter of the hot water device. Therefore, controlling the operation of the first hot water pump and / or the hot water device according to the hot water control parameters includes controlling the first hot water pump to operate with the first operating parameter and controlling the hot water device to operate with the second operating parameter. Based on this, the step of determining the hot water control parameters based on the water temperature includes:

[0134] When the water temperature is less than or equal to the third preset temperature, the second operating parameter is determined to increase the hot water temperature output by the hot water device to the water circulation system; when the water temperature is greater than the third preset temperature, the first operating parameter is determined to increase the speed of the first hot water pump.

[0135] In this embodiment, the third preset temperature is equal to the first preset temperature described above. In other embodiments, the third preset temperature may also be set to a temperature that is not equal to the first preset temperature.

[0136] The third preset temperature can be a fixed temperature set in advance, or it can be a temperature selected from multiple preset temperatures based on the current operating parameters of the heating module (such as the surface temperature of the heating module and / or the heating power of the heating module).

[0137] Specifically, the hot water device can increase its operating heating power to increase the temperature of the hot water it outputs to the water circulation system.

[0138] The adjustment parameters for the hot water device to increase the water temperature and / or the speed adjustment parameters for the first hot water pump can be determined based on the temperature difference between the current water temperature and the third preset temperature.

[0139] In this embodiment, when the water temperature is low, the temperature of the hot water supplied by the hot water device is increased by controlling the hot water device, thereby ensuring that the heating efficiency of the air conditioner can be effectively improved when it inputs hot water into the water circulation system. When the water temperature is high, increasing the speed of the first hot water pump helps to further increase the heat supply of the hot water device to the water circulation system, thus effectively improving the heating efficiency of the air conditioner.

[0140] Furthermore, in this embodiment, when the water temperature is greater than the third preset temperature, if the water temperature is less than or equal to the fourth preset temperature, then the step of determining the first operating parameter as increasing the speed of the first hot water pump is executed; when the water temperature is greater than the third preset temperature, if the water temperature is greater than the fourth preset temperature, then the first operating parameter is determined as decreasing the speed of the first hot water pump; the fourth preset temperature is greater than the third preset temperature.

[0141] In this embodiment, the fourth preset temperature is greater than the second preset temperature described above. In other embodiments, the fourth preset temperature may be equal to or less than the second preset temperature described above.

[0142] The fourth preset temperature can be a fixed temperature set in advance, or it can be a temperature selected from multiple preset temperatures based on the current operating parameters of the heating module (such as the surface temperature of the heating module and / or the heating power of the heating module).

[0143] In this embodiment, reducing the speed of the first hot water pump can specifically mean reducing the speed to 0 (i.e., turning off the first hot water pump). In other embodiments, the speed of the first hot water pump can also be reduced to a low speed.

[0144] In this embodiment, when the water temperature is higher than the fourth preset temperature, it indicates that the water temperature of the indoor heat exchanger is high enough and the heat output is large enough. At this time, reducing the speed of the first hot water pump helps to prevent the air conditioner from overheating and causing operational reliability issues in its circulation system, thereby ensuring that the air conditioner can heat up quickly while operating reliably. When the water temperature is high but has not reached the fourth preset temperature, increasing the speed of the first hot water pump can ensure the air conditioner's operational reliability and maximize its heating capacity to effectively raise the indoor ambient temperature.

[0145] To better understand the scheme of this embodiment, a specific application example is given below: The first and third preset temperatures are defined as T1, with a value range of [30℃, 55℃]; the second preset temperature is defined as T2, with a value range of [35℃, 60℃]; and the fourth preset temperature is defined as T3, with a value range of [40℃, 70℃]. Based on this, when the water temperature has not reached T1, the indoor fan speed is reduced or the hot water temperature is increased; when the water temperature reaches T1, the speed of the first hot water pump is increased; when the water temperature reaches T2, the indoor fan speed is increased; and when the water temperature reaches T3, the first hot water pump is turned off.

[0146] Furthermore, based on any of the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, reference is made to... Figure 7 After step S20, the following steps are also included:

[0147] Step S50: Obtain the indoor ambient temperature;

[0148] Step S60: When the indoor ambient temperature is greater than or equal to the set ambient temperature, if the target operating noise of the air conditioner is less than the set noise threshold or the current operating noise of the air conditioner, then control the refrigerant circulation system and the water circulation system to shut down, and control the heating module to remain on.

[0149] Controlling the shut-off of the refrigerant circulation system and the water circulation system specifically refers to shutting off the compressor and the indoor fan in the refrigerant circulation system.

[0150] When the user inputs a second command indicating priority for quiet operation, it can be determined that the target operating noise of the air conditioner is less than a set noise threshold or the current operating noise of the air conditioner; otherwise, it can be determined that the target operating noise of the air conditioner is greater than or equal to the set noise threshold or the current operating noise of the air conditioner. Alternatively, by obtaining the current time, if the current time period falls within a preset rest period (such as nighttime or midday sleep), it can be determined that the target operating noise of the air conditioner is less than the set noise threshold or the current operating noise of the air conditioner; if the current time period falls outside the preset rest period, it can be determined that the target operating noise of the air conditioner is greater than or equal to the set noise threshold or the current operating noise of the air conditioner.

[0151] In this embodiment, when the air conditioner requires quiet operation, the noise of the air conditioner can be effectively reduced by shutting down the refrigerant circulation system and the water circulation system. At the same time, the heating module remains on to maintain the heating of the indoor air or supplement the heat required by the human body, so as to meet the indoor heating needs while meeting the user's quietness needs, and effectively improve the user's comfort.

[0152] Furthermore, in this embodiment, the water circulation system further includes a circulating water pump and an indoor fan corresponding to the indoor heat exchanger. The circulating water pump is located in the connecting pipe between the indoor heat exchanger and the outdoor heat exchanger. The circulating water pump is used to drive water to circulate between the indoor heat exchanger and the outdoor heat exchanger. The step of controlling the shut-off of the refrigerant circulation system and the water circulation system includes:

[0153] Step S51: Control the refrigerant circulation system to shut down;

[0154] Step S52: When the refrigerant circulation system has been shut down for a set time, control the circulating water pump to shut down;

[0155] Step S53: When the circulating water pump is in the off state, the indoor fan speed is reduced according to the temperature of the indoor heat exchanger until the indoor fan is turned off. The speed of the indoor fan decreases as the temperature of the indoor heat exchanger decreases.

[0156] The fan speed will decrease until it shuts off as the indoor ambient temperature decreases.

[0157] In this embodiment, the refrigerant circulation system is first shut down, and the water in the water circulation system is kept circulating for a period of time before the circulating water pump is shut down. After the circulating water pump is shut down, the indoor fan speed is continuously reduced based on the indoor heat exchanger temperature until it is shut down, thereby ensuring that the heat from the heat pump module can be fully used to heat the indoor environment and improve the heating efficiency of the air conditioner.

[0158] It should be noted that when step S20 includes steps S30 and S40, after obtaining the indoor ambient temperature, if the target operating noise of the air conditioner is greater than or equal to the set ambient temperature when the indoor ambient temperature is greater than or equal to the set ambient temperature, then steps S30 and S40 can be executed.

[0159] Furthermore, after the step of obtaining the operating mode of the air conditioner, the method further includes:

[0160] When the operating mode is cooling mode, or when the operating mode is heating mode and the target heating capacity of the air conditioner is less than the set heating capacity or the current heating capacity of the air conditioner, if there is a water intake command from the water-using device outside the air conditioner, the refrigerant circulation system is controlled to operate in heating mode, the water circulation system is controlled to start, and the second hot water pump of the air conditioner is controlled to start. When the second hot water pump is started, part of the hot water in the water circulation system is sent to the water-using device.

[0161] When the operating mode is the heating mode and the target heating capacity is greater than the set heating capacity or the current heating capacity of the air conditioner, the steps of controlling the refrigerant circulation system to operate in heating mode, controlling the water circulation system to start, and controlling the heating module to start are executed, and the second hot water pump is controlled to shut down.

[0162] The target heating capacity of an air conditioner in heating mode can be obtained by acquiring user commands, or by monitoring the current scene parameters of the indoor environment or the actual operating parameters of the air conditioner, and analyzing the monitored scene parameters or operating parameters to determine the target heating capacity. For example, if there is a first command indicating priority for heating capacity, the target heating capacity can be determined to be greater than the set heating capacity or the current heating capacity of the air conditioner; if there is no first command indicating priority, the target heating capacity can be determined to be less than the set heating capacity. Alternatively, the target heating capacity can be determined by detecting the indoor ambient temperature. If the temperature difference between the detected indoor ambient temperature and the air conditioner's set temperature is less than the set temperature difference value, it indicates that the indoor space basically meets the user's comfort needs, and the target heating capacity can be determined to be less than the set heating capacity or the current heating capacity of the air conditioner. If the temperature difference between the detected indoor ambient temperature and the air conditioner's set temperature is greater than the set temperature difference value, it indicates that the indoor space does not yet meet the user's comfort needs, and the target heating capacity can be determined to be greater than the set heating capacity or the current heating capacity of the air conditioner.

[0163] When the target heating capacity required by the air conditioner is low when it is off or in heating mode, it indicates that the air conditioner requires less heat for air heat exchange or even no heat exchange at all. At this time, the air conditioner heats the water by circulating the refrigerant and the water circulation system is turned on to heat the water in the water circulation system. The second hot water pump is turned on so that the air conditioner can provide hot water to the external water-using device, ensuring that the water-using device can meet the user's water needs even if the hot water function of the water-using device fails or does not have a hot water function.

[0164] When the target heating capacity required in the air conditioner's heating mode is large, it indicates that the air conditioner needs a large amount of hot water to heat the air. At this time, the second hot water pump is turned off to prevent hot water from being supplied to the outside. The water circulation system, refrigerant circulation system and heating module are turned on in coordination to achieve rapid heating of the indoor environment and meet the thermal comfort needs of indoor users.

[0165] Specifically, when the air conditioner is in heating mode and the target heating capacity is less than the set heating capacity or the current heating capacity of the air conditioner, the heating module can be turned on or off. Specifically, when the second hot water pump is on, it can control the heating module to turn on. When the heating module is located outside the casing, it can maintain heating of the indoor environment while simultaneously providing hot water to external devices through the water circulation system, thus meeting both the user's thermal comfort and water usage needs. When the heating module is located inside the air duct, it can be turned on while providing hot water to external devices through the water circulation system. Turning on the heating module avoids heat loss in the water circulation system and allows it to work in conjunction with the refrigerant circulation to improve the heating efficiency of the hot water in the water circulation system, ensuring that the air conditioner provides sufficiently high-temperature hot water to water-using devices in a timely manner to meet the user's water usage needs.

[0166] When the secondary hot water pump is turned on, the circulating water pump can be turned on or off. Specifically, when the circulating water pump is turned off, it can increase the rate at which the hot water temperature in the outdoor heat exchanger rises, so as to quickly provide hot water of sufficient temperature to the water-using devices; when the circulating water pump is turned on, it can enable the air conditioner to meet the external water demand while maintaining heat exchange with the air, thus effectively balancing the user's water demand and comfort needs.

[0167] Furthermore, this invention also proposes a computer-readable storage medium storing a control program for an air conditioner. When the control program is executed by a processor, it implements the relevant steps of any of the above-described air conditioner control methods.
