During the refrigeration or heating operation of the air conditioner, when the first environmental temperature in the indoor space reaches the temperature-stop condition, if the fresh air device is turned on, the compressor is turned off while the indoor fan remains on. Driven by the indoor fan, the indoor air enters the indoor air duct and mixes with the fresh air to adjust the temperature of the fresh air. The fresh air can also be temperature-adjusted through the residual heat of the indoor heat exchanger. This can prevent the fresh air from directly entering the indoor space without treatment, causing fluctuations in the indoor temperature and resulting in frequent start-stop of the compressor, thereby effectively improving the operation reliability of the compressor. In addition, when the air conditioner needs to turn on a second target mode with a heat exchange state different from the current indoor heat exchanger and the fresh air device is turned on, during the process of controlling the air conditioner to operate in the second target mode, the fresh air volume introduced by the fresh air device is restricted not to exceed the target fresh air volume, avoiding large fluctuations in the indoor temperature caused by the introduction of a large amount of fresh air during the operation of the second target mode and affecting the user's comfort, thereby improving the indoor comfort when the air conditioner switches from the first target mode to the second target mode. Based on this, when the air conditioner reaches the temperature-stop condition and / or switches to the second target mode and turns on, the influence of the fresh air device being turned on on the operation of the air conditioner and the indoor environment is considered. The fresh air device and the air conditioner no longer operate independently, thereby effectively improving the compatibility of the operation of the air conditioner and the fresh air device, meeting the indoor comfort and ensuring the reliable operation of the air conditioner.

The memory 1002 can be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. Optionally, the memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0056] Those skilled in the art can understand, Figure 2The device structure shown does not constitute a limitation on the device, and it may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0057] As Figure 2 shown, the memory 1002, as a storage medium, may include a control program for the environmental conditioning device. In the Figure 2 device shown, the processor 1001 may be used to call the control program for the environmental conditioning device stored in the memory 1002 and perform the relevant step operations of the control method for the environmental conditioning device in the following embodiments.

[0058] An embodiment of the present invention also provides a control method for an environmental conditioning device, which is applied to the above-mentioned environmental conditioning device.

[0059] Referring to Figure 3 , an embodiment of the control method for the environmental conditioning device of the present application is proposed. In this embodiment, the control method for the environmental conditioning device includes:

[0060] Step S10, controlling the air conditioner to operate in a first target mode, where the first target mode includes a cooling mode or a heating mode;

[0061] In the cooling mode, the compressor is turned on, the indoor fan is turned on, and the indoor heat exchanger is an evaporator; in the heating mode, the compressor is turned on, the indoor fan is turned on, and the indoor heat exchanger is a condenser.

[0062] Step S20, when the first environmental temperature of the indoor space adjusted by the environmental conditioning device meets the temperature-reached shutdown condition, and when the fresh air device is in the on state, controlling the compressor of the air conditioner to turn off and controlling the indoor fan to remain on; and / or, when the air conditioner runs to meet the start condition of the second target mode and the fresh air device is in the on state, controlling the air conditioner to run in the second target mode and controlling the fresh air device to run so that the introduced fresh air volume is less than the target fresh air volume, where the heat exchange states of the indoor heat exchanger corresponding to the first target mode and the second target mode are different.

[0063] During the operation in the first target mode, the first environmental temperature of the indoor space can be detected in real time or at intervals of a preset duration. When the detected first environmental temperature meets the temperature-reached shutdown condition, it can be detected whether the fresh air device is currently in the on state. When it is detected that the fresh air device is in the on state, the compressor can be controlled to turn off and the indoor fan can be controlled to remain on. When the indoor fan remains on, it can maintain the current rotation speed or be adjusted to a preset rotation speed; when it is detected that the fresh air device is in the off state, the compressor can be controlled to turn off and the indoor fan can be controlled to turn off.

[0064] When the first target mode is the cooling mode, when the first ambient temperature is less than or equal to the set temperature of the air conditioner, it can be determined that the condition for reaching the temperature and stopping is satisfied. Otherwise, it can be determined that the condition for reaching the temperature and stopping is not satisfied. In this embodiment, the set temperature can be reduced by a preset temperature difference and used as the first target temperature. When the first ambient temperature is less than or equal to the first target temperature, it can be determined that the condition for reaching the temperature and stopping is satisfied.

[0065] When the first target mode is the heating mode, when the first ambient temperature is greater than or equal to the set temperature of the air conditioner, it can be determined that the condition for reaching the temperature and stopping is satisfied. Otherwise, it can be determined that the condition for reaching the temperature and stopping is not satisfied. In this embodiment, the set temperature can be increased by a preset temperature difference and used as the second target temperature. When the first ambient temperature is greater than or equal to the second target temperature, it can be determined that the condition for reaching the temperature and stopping is satisfied.

[0066] During the operation of the first target mode, if a start instruction for the second target mode is received, or it is monitored that the environmental parameters of the environment where the air conditioner is located reach the target conditions required for the second target mode to start, or it is monitored that the state parameters of the air conditioner itself reach the target conditions required for the second target mode to start, it can be considered that the second target mode reaches the start condition. For example, in this embodiment, the first target mode is the heating mode, the second target mode is the defrosting mode. During the operation of the first target mode, the temperature of the outdoor heat exchanger is detected. When the temperature of the outdoor heat exchanger is less than the first preset temperature (less than or equal to the freezing point temperature), it can be considered that the operation of the air conditioner reaches the start condition. When the second target mode reaches the start condition, it can be detected whether the fresh air device is in the on state. When the fresh air device is in the on state, control the air conditioner to operate in the second target mode and control the fresh air device to reduce the introduced fresh air volume.

[0067] Any component in the fresh air device related to the adjustment of the fresh air volume sent into the indoor air duct can be used as the target component. The parameter determined for the target component to reduce the fresh air volume is the target parameter, and the target component is controlled to operate according to the target parameter. The target component can include a fresh air valve provided at the fresh air inlet and / or the fresh air outlet, and / or a fresh air fan, etc.

[0068] In one implementation manner of this embodiment, the fresh air device includes a fresh air fan. Controlling the fresh air device to operate so that the introduced fresh air volume is less than the target fresh air volume includes: controlling the fresh air fan to operate at a speed less than the preset speed. Specifically, it can include controlling the fresh air fan to operate at a low speed (for example, the lowest speed) or to be turned off.

[0069] In another implementation manner of this embodiment, the fresh air device includes a fresh air valve provided at the fresh air outlet. Controlling the fresh air device to operate to reduce the fresh air volume sent into the indoor air duct includes: controlling the fresh air valve to operate at an opening less than the preset opening. Specifically, it can include controlling the fresh air valve to open or close at a small opening (for example, the smallest opening).

[0070] When the first target mode is the heating mode, the indoor heat exchanger is in the evaporation state under the second target mode, such as the defrosting mode; when the first target mode is the cooling mode, the indoor heat exchanger is in the condensation state under the second target mode, such as the sterilization mode, etc.

[0071] A control method for an environmental conditioning device proposed in an embodiment of the present invention. The device includes an air conditioner and a fresh air device. The indoor air duct of the air conditioner is communicated with the fresh air outlet of the fresh air device. An indoor heat exchanger and an indoor fan are arranged in the indoor air duct. During the cooling or heating operation of the air conditioner, when the first environmental temperature in the indoor space reaches the temperature-reached shutdown condition, if the fresh air device is turned on, the compressor is turned off while the indoor fan remains on. Driven by the indoor fan, the indoor air enters the indoor air duct to be mixed with the fresh air to adjust the temperature of the fresh air. The fresh air can also be temperature-adjusted through the residual heat of the indoor heat exchanger, which can avoid the indoor temperature fluctuation caused by the direct entry of fresh air into the indoor space without treatment, resulting in frequent start and stop of the compressor, thereby effectively improving the operation reliability of the compressor. In addition, when the air conditioner needs to turn on the second target mode with a heat exchange state different from the current indoor heat exchanger and the fresh air device is turned on, during the process of controlling the air conditioner to operate in the second target mode, the fresh air volume introduced by the fresh air device is restricted not to exceed the target fresh air volume, avoiding large fluctuations in indoor temperature caused by the introduction of a large amount of fresh air during the operation of the second target mode, which affects the comfort of users, thereby improving the indoor comfort when the air conditioner switches from the first target mode to the second target mode. Based on this, when the air conditioner reaches the temperature-reached shutdown and / or switches to the second target mode to turn on, the influence of the fresh air device being turned on on the operation of the air conditioner and the indoor environment is considered. The fresh air device and the air conditioner no longer operate independently, thereby effectively improving the compatibility of the operation of the air conditioner and the fresh air device, meeting indoor comfort and ensuring the reliable operation of the air conditioner.

[0072] Further, in the above embodiment, the first target mode includes the heating mode, the second target mode includes the defrosting mode, the indoor heat exchanger is in the heat release state under the heating mode, and the indoor heat exchanger is in the heat absorption state under the second target mode. Based on this, it can be ensured that when the air conditioner switches from the heating mode to the defrosting mode, the introduction of fresh air is avoided from causing a significant decrease in the indoor temperature, which is beneficial to improving the thermal comfort of indoor users during the defrosting process.

[0073] Further, in the above embodiment, when the first ambient temperature does not meet the temperature-reached shutdown condition, perform the step of controlling the air conditioner to operate in the second target mode and controlling the fresh air device to operate so that the introduced fresh air volume is less than the target fresh air volume when the air conditioner runs to meet the startup condition of the second target mode and the fresh air device is in the on state. Based on this, it can be ensured that the compressor of the air conditioner will not start and stop frequently after reaching the temperature and shutting down, which can improve the operating reliability of the compressor, and the indoor temperature will not fluctuate greatly when switching to the second target mode of operation, improving indoor comfort. The compatibility of the air conditioner with the fresh air device during both temperature-reached shutdown and switching of the operating mode can be effectively improved.

[0074] Further, in this embodiment, after step S10, it further includes:

[0075] When the first ambient temperature does not meet the temperature-reached shutdown condition and when the air conditioner does not run to meet the startup condition of the second target mode, it can return to execute step S10.

[0076] Further, based on the above embodiment, another embodiment of the control method of the environmental control device of the present application is proposed. In this embodiment, referring to Figure 4 , the fresh air device includes a fresh air fan and / or a fresh air valve provided at the fresh air outlet, and the step of controlling the fresh air device to operate so that the introduced fresh air volume is less than the target fresh air volume when the air conditioner runs to meet the startup condition of the second target mode and the fresh air device is in the on state includes:

[0077] Step S21, when the air conditioner runs to meet the startup condition of the second target mode and the fresh air device is in the on state, control the fresh air fan to close, and / or control the fresh air valve to close.

[0078] In this embodiment, control both the fresh air fan and the fresh air valve to close to prevent fresh air from entering the room during the operation of the second target mode and affecting user comfort.

[0079] In other embodiments, it is also possible to control the fresh air valve to open and control the fresh air fan to reverse to discharge the air in the indoor air duct to the outside through the fresh air duct, so as to reduce the temperature fluctuation in the room caused by the heat exchange of the indoor heat exchanger and improve the comfort of indoor users. Further, during the process of the fresh air valve opening and the fresh air fan reversing, the air outlet of the air conditioner can be controlled to close to reduce the heat loss in the room and improve the indoor comfort during the operation of the second target mode.

[0080] Further, in this embodiment, referring to Figure 4 , after step S21, it further includes:

[0081] Step S22, when the operation of the second target mode reaches the end condition, control the fresh air fan to turn on, and / or control the fresh air valve to turn on;

[0082] After step S22, return to execute the step of controlling the air conditioner to operate in the first target mode.

[0083] If a closing instruction for the second target mode is received, or it is monitored that the environmental parameters of the environment where the air conditioner is located reach the target conditions required for the end of the second target mode, or it is monitored that the state parameters of the air conditioner itself reach the target conditions required for the end of the second target mode, it can be considered that the operation of the second target mode reaches the end condition.

[0084] For example, in this embodiment, the second target mode is the defrosting mode. During the operation of the second target mode, the temperature of the outdoor heat exchanger is detected. When the temperature of the outdoor heat exchanger is greater than the second preset temperature (greater than or equal to the freezing point temperature), it can be considered that the operation of the second target mode reaches the end condition.

[0085] Further, based on any of the above embodiments, another embodiment of the control method of the environmental regulation device of the present application is proposed. In this embodiment, refer to Figure 5 , the step of controlling the compressor of the air conditioner to turn off and controlling the indoor fan to remain on when the first environmental temperature of the indoor space regulated by the environmental regulation device meets the temperature-reaching and shutdown condition and when the fresh air device is in the on state includes:

[0086] Step S23, when the first environmental temperature of the indoor space regulated by the environmental regulation device meets the temperature-reaching and shutdown condition and when the fresh air device is in the on state, control the compressor of the air conditioner to turn off and control the indoor fan to operate at a speed less than the preset speed.

[0087] In this embodiment, the indoor fan is controlled to operate at the lowest speed, and the preset speed is greater than the lowest speed. In other embodiments, the indoor fan can also be controlled to operate at a speed greater than the lowest speed and less than the preset speed.

[0088] Here, the preset speed can be less than or equal to 30% of the maximum allowable operating speed of the indoor fan.

[0089] In this embodiment, the indoor fan operates at a speed less than the preset speed, that is, the indoor fan operates at a low speed, which can reduce the fresh air volume sent into the indoor space after reaching the temperature and shutdown to avoid large fluctuations in the indoor temperature after reaching the temperature and shutdown, resulting in too short an interval time from when the compressor shuts down to when it is restarted again. It can effectively avoid frequent start and stop of the compressor and improve the operation reliability of the compressor.

[0090] In other embodiments, the indoor fan can also operate at a speed greater than the preset speed.

[0091] Further, in this embodiment, the step of controlling the indoor fan to maintain operation at a speed less than the preset speed includes:

[0092] Step S231, obtaining the return air temperature of the indoor air duct, the heat exchanger temperature of the indoor heat exchanger, and the state parameters related to the fresh air introduced by the fresh air device;

[0093] The return air temperature is specifically detected by an indoor parameter detection module provided at the air return opening.

[0094] The heat exchanger temperature is specifically detected by a temperature sensor provided on the indoor heat exchanger.

[0095] The state parameters include the air characteristic parameters of the fresh air (such as fresh air temperature and / or fresh air humidity, etc.) and / or the operating parameters of the fresh air device (such as fresh air fan speed and / or the opening degree of the fresh air valve, etc.).

[0096] Step S232, determining the target speed of the indoor fan within the speed range less than the preset speed according to the return air temperature, the heat exchanger temperature, and the state parameters;

[0097] Different return air temperatures, different heat exchanger temperatures, and different state parameters correspond to different target speeds. The corresponding relationship between the return air temperature, the heat exchanger temperature, and the state parameters and the target speed can be preset in advance. The corresponding relationship can include forms such as calculation relationships and mapping relationships. Based on this corresponding relationship, the target speed corresponding to the current return air temperature, heat exchanger temperature, and state parameters can be determined.

[0098] Further, in this embodiment, if the state parameters include the fresh air temperature and the operating speed of the fresh air fan in the fresh air device, then step S232 includes: determining the first temperature difference between the return air temperature and the heat exchanger temperature, determining the second temperature difference between the fresh air temperature and the heat exchanger temperature, and determining the third temperature difference between the return air temperature and the fresh air temperature; determining a speed adjustment value according to the first temperature difference, the second temperature difference, the third temperature difference, and the operating speed; and reducing the preset speed according to the speed adjustment value to obtain the target speed.

[0099] The speed adjustment value can include a speed adjustment ratio or a speed adjustment amplitude, etc. Specifically, the target speed can be obtained by subtracting the speed adjustment amplitude from the preset speed. The target speed can also be obtained by multiplying the preset speed by the speed adjustment ratio.

[0100] Among them, a preset formula between the first temperature difference, the second temperature difference, the third temperature difference, and the operating speed and the speed adjustment value can be established in advance, and the first temperature difference, the second temperature difference, the third temperature difference, and the operating speed are substituted into the preset formula to calculate the speed adjustment value. It is also possible to obtain the target correspondence relationship between the first temperature difference, the second temperature difference, the third temperature difference, and the speed adjustment value based on the operating speed. Different operating speeds correspond to different target correspondence relationships (such as calculation formulas, mapping tables, etc.). Based on this target correspondence relationship, the speed adjustment value corresponding to the current first temperature difference, second temperature difference, and third temperature difference can be determined.

[0101] Specifically, a first correction value can be determined based on the first temperature difference, a second correction value can be determined based on the second temperature difference and the operating speed, a third correction value can be determined based on the third temperature difference and the operating speed. The speed adjustment value is determined according to the first correction value, the second correction value, and the third correction value, and the target speed is obtained by reducing the preset speed according to the speed adjustment value.

[0102] Step S233, control the indoor fan to operate at the target speed.

[0103] In this embodiment, determining the target speed of the indoor fan operation after the air conditioner reaches the set temperature and stops based on the return air temperature, the heat exchanger temperature, and the state parameters related to the fresh air introduction is beneficial to improving the accuracy of the indoor fan operating speed, avoiding frequent opening and closing of the compressor while ensuring sufficient fresh air volume indoors to maintain freshness, which is beneficial to improving the balance between the indoor temperature and freshness after reaching the set temperature and stopping, ensuring the reliable operation of the compressor while further improving the comfort of indoor users. In particular, the first temperature difference, the second temperature difference, the third temperature difference, and the operating speed can comprehensively reflect the impact on the indoor environmental state during the fresh air introduction process. Determining the target speed based on the first temperature difference, the second temperature difference, the third temperature difference, and the operating speed is beneficial to further effectively balance the reliable operation of the compressor and the comfort of indoor users.

[0104] Further, based on any of the above embodiments, another embodiment of the control method of the environmental adjustment device of the present application is proposed. In this embodiment, the side of the indoor air duct where the return air outlet is located is defined as the air inlet side, the fresh air outlet is communicated with the air inlet side, and an indoor parameter detection module is provided at the return air outlet. After the step of controlling the compressor of the air conditioner to close and controlling the indoor fan to remain on when the first environmental temperature of the indoor space adjusted by the environmental adjustment device meets the condition of reaching the set temperature and stopping and when the fresh air device is in the on state, it further includes: obtaining the second environmental temperature of the indoor space, and the second environmental temperature is detected by the indoor parameter detection module; when the second environmental temperature meets the exit condition of reaching the set temperature and stopping, control the compressor to turn on.

[0105] Specifically, when the compressor is turned off and the indoor fan remains on, the temperature data currently detected by the indoor parameter detection module can be obtained as the second ambient temperature.

[0106] When the first target mode is the cooling mode, when the second ambient temperature is greater than the set temperature, it can be considered that the exit condition for reaching the temperature and stopping is met.

[0107] When the first target mode is the heating mode, when the second ambient temperature is less than the set temperature, it can be considered that the exit condition for reaching the temperature and stopping is met.

[0108] Among them, after step S40, it can return to execute step S10.

[0109] In this embodiment, by determining whether to restart the compressor based on the detected second ambient temperature when the indoor fan remains on after reaching the temperature and stopping, it can avoid the error of the indoor parameter detection module for the detected ambient temperature during the process of the fresh air directly entering the room from the return air outlet, resulting in the compressor being mis-started too quickly, thereby further avoiding the frequent start and stop of the compressor and further improving the operation reliability of the compressor.

[0110] In addition, an embodiment of the present invention also proposes a storage medium, on which a control program for an environmental control device is stored. When the control program for the environmental control device is executed by a processor, the relevant steps of any one of the above embodiments of the control method for the environmental control device are implemented.
