[0065] Those skilled in the art will understand that Figure 2 The device structure shown in the figure does not constitute a limitation of the device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0066] like Figure 2 As shown, the memory 1002 as a storage medium may include a control program of the environment adjustment device.

[0067] An embodiment of the present invention further provides a control method for an environmental conditioning device, which is applied to the above-mentioned environmental conditioning device.

[0068] Reference Figure 3 , an embodiment of a control method for the environment conditioning device of the present application is proposed. In this embodiment, the environment conditioning device includes an air conditioner and a fresh air device, the indoor air duct of the air conditioner is connected to the fresh air outlet of the fresh air device, the indoor air duct is provided with an indoor heat exchanger, and the control method of the environment conditioning device includes:

[0069] Step S10, when the air conditioner is in a target state, controlling the fresh air device to operate, and obtaining indoor environmental parameters of the indoor space regulated by the environmental conditioning device and fresh air parameters of the fresh air introduced by the fresh air device; wherein the target state includes the indoor heat exchanger stopping heat exchange;

[0070] The air conditioner can monitor the environmental parameters of the indoor space, and control the air conditioner to operate in a target state when the environmental parameters meet the set conditions; in addition, the air conditioner can also be controlled to operate in a target state when a preset instruction input by the user is received; or, the air conditioner can be controlled to operate in a target state when a power-on instruction input by the user is not received. When the indoor heat exchanger stops exchanging heat, the compressor in the refrigerant circulation loop in which it is located can be turned off, or when the indoor heat exchanger stops exchanging heat, the compressor in the refrigerant circulation loop in which it is located is turned on and the flow valve in series with the indoor heat exchanger is closed.

[0071] The indoor environmental parameters are specifically parameters directly obtained and / or calculated by acquiring the data currently detected by the indoor parameter detection module. The indoor environmental parameters include indoor environmental temperature, indoor environmental humidity and / or indoor moisture content, etc.

[0072] The fresh air parameters may specifically include parameters of the air characteristics of the fresh air itself (fresh air humidity, fresh air temperature and / or fresh air moisture content, etc.) and / or operating parameters of the fresh air device related to the introduction of fresh air (for example, the opening and closing of the fresh air valve at the fresh air outlet, the opening degree of the fresh air valve at the fresh air outlet, the operating speed of the fresh air fan, etc.).

[0073] Step S20, when the fresh air parameter and the indoor environment parameter reach a preset condition that the environmental conditioning device has a condensation risk, the fresh air device is controlled to operate to reduce the amount of fresh air supplied to the indoor air duct.

[0074] The preset conditions may specifically include the target size relationship or target quantity relationship that the fresh air parameters and indoor environmental parameters need to achieve when there is a condensation risk in the environmental conditioning equipment, or the preset conditions may also include the target value range that the fresh air parameters and indoor environmental parameters need to achieve when there is a condensation risk in the environmental conditioning equipment, or the target quantity relationship that they need to achieve with the corresponding preset thresholds, etc.

[0075] When the fresh air parameters and indoor environmental parameters meet the preset conditions, it can be considered that there is a condensation risk in the indoor air duct and / or there is a condensation risk in the fresh air duct. When the fresh air parameters and indoor environmental parameters do not meet the preset conditions, it can be considered that there is no condensation risk in the indoor air duct and the fresh air duct.

[0076] Any component in the fresh air device that is related to the fresh air volume adjustment sent to the indoor air duct can be used as a target component, and the parameter of the target component used to reduce the fresh air volume is determined as the target parameter, and the target component is controlled to operate according to the target parameter. The target component may include a fresh air valve and / or a fresh air fan provided on the fresh air inlet and / or the fresh air outlet.

[0077] In one implementation of this embodiment, the fresh air device includes a fresh air fan, and controlling the operation of the fresh air device to reduce the amount of fresh air delivered to the indoor air duct includes: controlling the fresh air fan to reduce the operating speed or controlling the fresh air fan to shut down. The fresh air fan can reduce the operating speed to the minimum speed or reduce the speed according to a preset speed adjustment range.

[0078] In another implementation of this embodiment, the fresh air device includes a fresh air valve provided at the fresh air outlet, and controlling the operation of the fresh air device to reduce the amount of fresh air delivered to the indoor air duct includes: controlling the fresh air valve to close or controlling the fresh air valve to reduce the opening. When the fresh air valve reduces the opening, it can be reduced to the minimum opening for operation, or it can be reduced according to a preset opening adjustment range for operation.

[0079] A control method for an environmental conditioning device is proposed in an embodiment of the present invention. The device includes an air conditioner and a fresh air device. The air outlet of the fresh air device is connected to an indoor air duct of the air conditioner. An indoor heat exchanger is provided in the indoor air duct. According to the method, when the indoor heat exchanger in the air conditioner stops exchanging heat and the fresh air device is in operation, the fresh air introduced by the fresh air device can be mixed with the indoor air in the indoor air duct and then delivered to the room. In this process, indoor environmental parameters of the indoor space regulated by the environmental conditioning device and fresh air parameters of the fresh air introduced by the fresh air device are obtained. When the fresh air parameters and the indoor environmental parameters reach preset conditions, it can be considered that the environmental conditioning device has a condensation risk. At this time, the fresh air device is controlled to operate to reduce the amount of fresh air delivered to the indoor air duct, thereby reducing the heat difference between the indoor air inside the environmental conditioning device and the introduced fresh air, avoiding condensation inside the environmental conditioning device, and ensuring that the environmental conditioning device can be used normally.

[0080] Furthermore, in the present embodiment, an indoor fan is also provided in the indoor air duct, and the target state also includes turning on the indoor fan. In the present embodiment, the preset speed is the minimum speed. In other embodiments, the preset speed may also be a speed greater than the minimum speed. When the indoor heat exchanger stops exchanging heat, the compressor of the air conditioner stops running, indicating that the indoor space currently does not have a heat exchange demand. Turning on the indoor fan in this process is conducive to allowing the indoor air to enter the indoor air duct and mix with the introduced fresh air, and promote indoor air flow, reduce the deviation caused by the introduction of fresh air to the detection of indoor environmental parameters, and improve the accuracy of subsequent judgments on whether there is a condensation risk in the environmental conditioning equipment, thereby improving the accuracy of the operation and regulation of the fresh air device, so that the fresh air device can have as large a volume of fresh air as possible to be delivered to the room on the basis of avoiding condensation, thereby ensuring indoor comfort.

[0081] Further, based on the above embodiment, another embodiment of the control method of the environmental conditioning device of the present application is proposed. In this embodiment, referring to Figure 4 , the indoor environment parameter includes a first indoor environment temperature, the fresh air parameter includes a fresh air dew point temperature, the preset condition includes that the first indoor environment temperature is less than the fresh air dew point temperature, and controlling the operation of the fresh air device to reduce the amount of fresh air supplied to the indoor air duct includes:

[0082] Step S21, determining a first temperature difference between the fresh air dew point temperature and the first indoor ambient temperature;

[0083] The first indoor ambient temperature is defined as T1, the fresh air dew point temperature is defined as T2, and the first temperature difference value is T2-T1.

[0084] Step S22: controlling the operation of the fresh air device according to the first temperature difference value to reduce the amount of fresh air supplied to the indoor air duct.

[0085] Different first temperature difference values ​​correspond to different reductions in the fresh air volume. The reduction is positively correlated with the first temperature difference value. Alternatively, different first temperature difference values ​​correspond to different target air volumes after the fresh air volume is reduced, and the target air volume is negatively correlated with the first temperature difference value.

[0086] Specifically, based on the correspondence between the first temperature difference and the reduction range or the target air volume, a correspondence between the first temperature difference and the operating parameters of the fresh air device for reducing the fresh air volume can be pre-established, and the correspondence can be in the form of a calculation relationship, a mapping relationship, etc. Based on the correspondence, the target operating parameters of the fresh air device corresponding to the current first temperature difference can be determined, and the operation of the fresh air device can be controlled according to the target operating parameters.

[0087] In this embodiment, the first temperature difference value can characterize the current condensation risk of the environmental conditioning equipment, and is suitable for controlling the operation of the fresh air device with the first temperature difference value, which is beneficial to improving the accuracy of the operation regulation of the fresh air device, thereby achieving an effective balance between anti-condensation of the environmental conditioning equipment and indoor comfort.

[0088] In other embodiments, a quantitative relationship or mapping table between the fresh air dew point temperature and the indoor ambient temperature and the operating parameters of the fresh air device (such as the fresh air fan speed or the fresh air valve opening, etc.) can be established in advance, and the target operating parameters of the fresh air device for reducing the fresh air volume can be obtained by directly calculating or looking up the table based on the fresh air dew point temperature and the indoor ambient temperature.

[0089] Furthermore, in the present embodiment, the fresh air device includes a fresh air fan and / or a fresh air valve arranged at the fresh air outlet, and step S22 includes: when the first temperature difference value is greater than the first preset temperature difference, controlling the fresh air fan and / or the fresh air valve to close; when the first temperature difference value is less than or equal to the first preset temperature difference, controlling the fresh air fan to reduce the speed.

[0090] The first preset temperature difference is specifically a critical temperature difference value used to distinguish the magnitude of condensation risk.

[0091] In this embodiment, the fresh air device includes a fresh air fan and a fresh air valve, and the fresh air fan and the fresh air valve are controlled to be closed. In other embodiments, when the fresh air device includes one of the fresh air fan and the fresh air valve, the fresh air fan can be controlled to be closed or the fresh air valve can be controlled to be closed.

[0092] Specifically, during the process of controlling the fresh air fan to reduce its speed, when the current speed of the fresh air fan is greater than the minimum speed, the fresh air fan is controlled to reduce to the minimum speed; when the current speed of the fresh air fan is the minimum speed, the fresh air fan is controlled to be turned off.

[0093] When the first temperature difference value is greater than the first preset temperature difference, it indicates that the condensation risk is high at this time. The fresh air fan and the fresh air valve are closed to stop introducing fresh air, so as to effectively reduce the condensation risk of the environmental conditioning equipment. When the first temperature difference value is less than or equal to the first preset temperature difference, it indicates that the condensation risk is low at this time. The fresh air fan is operated at a lower speed to ensure the introduction of fresh air while maintaining indoor comfort and reducing the condensation risk of the environmental conditioning equipment.

[0094] Furthermore, in this embodiment, before the step of obtaining the indoor environmental parameters of the indoor space regulated by the environmental conditioning device and the fresh air parameters of the fresh air device introducing fresh air, the step further includes: controlling the fresh air device to operate and detecting a second indoor environmental temperature and an outdoor environmental temperature when the air conditioner is in a target state;

[0095] The step of obtaining the indoor environmental parameters of the indoor space regulated by the environmental conditioning equipment and the fresh air parameters of the fresh air introduced by the fresh air device includes: when the second indoor environmental temperature is greater than or equal to the outdoor environmental temperature, detecting the first indoor environmental temperature and the fresh air dew point temperature, the indoor environmental parameters include the first indoor environmental temperature, and the fresh air parameters include the fresh air dew point temperature.

[0096] After the first indoor ambient temperature and the fresh air dew point temperature are detected, the above-mentioned step S21 may be executed.

[0097] The outdoor ambient temperature can be specifically obtained by acquiring the data detected by the outdoor parameter detection module.

[0098] The first indoor ambient temperature and the second indoor ambient temperature can be specifically obtained by acquiring data detected by the indoor parameter detection module.

[0099] The fresh air dew point temperature can be specifically obtained by obtaining the fresh air temperature and fresh air humidity detected by the fresh air parameter detection module, and calculating the fresh air dew point temperature here by using the fresh air temperature and fresh air humidity.

[0100] In this embodiment, the relationship between the second indoor ambient temperature and the outdoor ambient temperature can reflect the indoor and outdoor temperatures. Condensation risk will occur only when high-temperature air meets low-temperature air. Therefore, when the outdoor temperature is lower than the indoor temperature, the first indoor ambient temperature is used as the indoor ambient parameter and the fresh air dew point temperature is used as the fresh air parameter. This allows the first indoor ambient temperature and the fresh air dew point temperature to be used to accurately identify whether low-temperature fresh air entering the indoor air duct will cause condensation risk in the indoor air duct, thereby ensuring that when there is a condensation risk in the indoor air duct, the condensation risk is reduced in time by adjusting the operation of the fresh air device.

[0101] Further, based on any of the above embodiments, another embodiment of the control method of the environmental conditioning device of the present application is proposed. In this embodiment, the indoor environmental parameters include the indoor dew point temperature, the fresh air parameters include the fresh air temperature, the preset conditions include that the fresh air temperature is less than the indoor dew point temperature, and the indoor dew point temperature is specifically calculated by obtaining the indoor temperature and indoor humidity detected by the indoor parameter detection module. The fresh air temperature is detected by the fresh air parameter detection module. Figure 5 The step of controlling the operation of the fresh air device to reduce the amount of fresh air delivered to the indoor air duct comprises:

[0102] Step S23, determining a second temperature difference between the indoor dew point temperature and the fresh air temperature;

[0103] The indoor dew point temperature is defined as T3, the fresh air temperature is defined as T4, and the first temperature difference is T3-T4.

[0104] Step S24: controlling the operation of the fresh air device according to the second temperature difference to reduce the amount of fresh air supplied to the indoor air duct.

[0105] Different second temperature difference values ​​correspond to different reductions in the fresh air volume. The reduction is positively correlated with the second temperature difference value. Alternatively, different second temperature difference values ​​correspond to different target air volumes after the fresh air volume is reduced, and the target air volume is negatively correlated with the second temperature difference value.

[0106] Specifically, based on the correspondence between the second temperature difference and the reduction range or the target air volume, a correspondence between the second temperature difference and the operating parameters of the fresh air device for reducing the fresh air volume can be pre-established, and the correspondence can be in the form of a calculation relationship, a mapping relationship, etc. Based on the correspondence, the target operating parameters of the fresh air device corresponding to the current second temperature difference can be determined, and the operation of the fresh air device can be controlled according to the target operating parameters.

[0107] In this embodiment, the second temperature difference value can characterize the current condensation risk of the environmental conditioning equipment, and is suitable for controlling the operation of the fresh air device with the second temperature difference value, which is beneficial to improving the accuracy of the operation regulation of the fresh air device, thereby achieving an effective balance between anti-condensation of the environmental conditioning equipment and indoor comfort.

[0108] In other embodiments, a quantitative relationship or mapping table between the indoor dew point temperature and the fresh air temperature and the operating parameters of the fresh air device (such as the fresh air fan speed or the fresh air valve opening, etc.) can be established in advance, and the target operating parameters of the fresh air device for reducing the fresh air volume can be obtained by directly calculating or looking up the table based on the indoor dew point temperature and the fresh air temperature.

[0109] Furthermore, in the present embodiment, the fresh air device includes a fresh air fan and a fresh air valve arranged at the fresh air outlet, and step S24 includes: when the second temperature difference value is greater than the second preset temperature difference, controlling the fresh air fan and / or the fresh air valve to close; when the second temperature difference value is less than or equal to the second preset temperature difference, controlling the fresh air fan to reduce the speed.

[0110] The second preset temperature difference is specifically a critical temperature difference value used to distinguish the magnitude of condensation risk.

[0111] In this embodiment, the fresh air device includes a fresh air fan and a fresh air valve, and the fresh air fan and the fresh air valve are controlled to be closed. In other embodiments, when the fresh air device includes one of the fresh air fan and the fresh air valve, the fresh air fan can be controlled to be closed or the fresh air valve can be controlled to be closed.

[0112] Specifically, during the process of controlling the fresh air fan to reduce its speed, when the current speed of the fresh air fan is greater than the minimum speed, the fresh air fan is controlled to reduce to the minimum speed; when the current speed of the fresh air fan is the minimum speed, the fresh air fan is controlled to be turned off.

[0113] When the second temperature difference is greater than the second preset temperature difference, it indicates that the condensation risk is high at this time. The fresh air fan and the fresh air valve are closed to stop introducing fresh air, so as to effectively reduce the condensation risk of the environmental conditioning equipment. When the second temperature difference is less than or equal to the second preset temperature difference, it indicates that the condensation risk is low at this time. The fresh air fan is operated at a lower speed to ensure the introduction of fresh air while maintaining indoor comfort and reducing the condensation risk of the environmental conditioning equipment.

[0114] Furthermore, in this embodiment, before the step of obtaining the indoor environmental parameters of the indoor space regulated by the environmental conditioning device and the fresh air parameters of the fresh air device introducing fresh air, the step further includes: controlling the fresh air device to operate and detecting a second indoor environmental temperature and an outdoor environmental temperature when the air conditioner is in a target state;

[0115] The step of obtaining the indoor environmental parameters of the indoor space regulated by the environmental conditioning equipment and the fresh air parameters of the fresh air introduced by the fresh air device includes: when the second indoor environmental temperature is lower than the outdoor environmental temperature, detecting the indoor dew point temperature and the fresh air temperature, the indoor environmental parameters including the indoor dew point temperature, and the fresh air parameters including the fresh air temperature.

[0116] After the indoor dew point temperature and the fresh air temperature are detected, the above-mentioned step S23 may be executed.

[0117] The indoor dew point temperature can be obtained by obtaining the indoor temperature and indoor humidity detected by the indoor parameter detection module. The fresh air temperature can be obtained by obtaining the data detected by the fresh air parameter detection module.

[0118] The second indoor ambient temperature can be specifically obtained by acquiring data detected by the indoor parameter detection module.

[0119] In this embodiment, the relationship between the second indoor ambient temperature and the outdoor ambient temperature can reflect the indoor and outdoor temperatures. There will be a risk of condensation only when high-temperature air meets low-temperature air. Therefore, when the indoor temperature is lower than the outdoor temperature, the indoor dew point temperature is used as the indoor ambient parameter and the fresh air temperature is used as the fresh air parameter. The indoor dew point temperature and the fresh air temperature can be used to accurately identify whether there is a risk of condensation in the fresh air duct during the process of introducing fresh air into the indoor air duct. When there is a risk of condensation in the fresh air duct, the risk of condensation is reduced in time by adjusting the operation of the fresh air device to avoid freezing of the fresh air duct when the outdoor temperature is low.

[0120] Further, based on any of the above embodiments, before the step of obtaining the indoor environmental parameters of the indoor space regulated by the environmental conditioning device and the fresh air parameters of the fresh air device introducing fresh air, the step further includes: controlling the fresh air device to operate and detecting a second indoor environmental temperature and an outdoor environmental temperature when the air conditioner is in a target state;

[0121] The step of obtaining the indoor environmental parameters of the indoor space adjusted by the environmental adjustment device and the fresh air parameters of the fresh air introduced by the fresh air device comprises:

[0122] When the second indoor environment temperature is greater than or equal to the outdoor environment temperature, detecting the first indoor environment temperature and the fresh air dew point temperature, the indoor environment parameter includes the first indoor environment temperature, and the fresh air parameter includes the fresh air dew point temperature;

[0123] When the second indoor environment temperature is lower than the outdoor environment temperature, the indoor dew point temperature and the fresh air temperature are detected, the indoor environment parameters include the indoor dew point temperature, and the fresh air parameters include the fresh air temperature.

[0124] Based on this, step S21 can be executed when the indoor environmental parameters include the first indoor environmental temperature and the fresh air parameters include the fresh air dew point temperature, and step S23 can be executed when the indoor environmental parameters include the indoor dew point temperature and the fresh air parameters include the fresh air temperature, thereby ensuring that the fresh air introduction process can effectively avoid condensation of the environmental conditioning equipment regardless of the relative high or low indoor and outdoor temperatures.

[0125] Further, based on any of the above embodiments, another embodiment of the control method of the environmental conditioning device of the present application is proposed. In this embodiment, an indoor fan is arranged in the indoor air duct, referring to Figure 6 The step of obtaining the indoor environmental parameters of the indoor space adjusted by the environmental adjustment device comprises:

[0126] Step S11, obtaining the location of the indoor parameter detection module;

[0127] The location may be the return air outlet of the indoor air duct, the outer wall of the environmental conditioning device, or a location outside the environmental conditioning device in the indoor space, etc.

[0128] The position here can be specifically determined by obtaining information input by the user, or by reading data pre-stored in the environmental conditioning device. It can also be obtained by sending a first instruction to the indoor parameter detection module and starting timing, receiving a second instruction returned by the indoor parameter detection module based on the first instruction and stopping timing, and obtaining the timing duration. If the timing duration is greater than the preset duration, the position can be determined to be a position outside the environmental conditioning device in the indoor space (for example, a wire controller for an air conditioner); if the timing duration is less than or equal to the preset duration, the position can be determined to be the return air outlet of the indoor air duct.

[0129] Step S12, controlling the operation of the indoor fan in the indoor air duct according to the position, and acquiring first data detected by the indoor parameter detection module;

[0130] Different positions may correspond to different operating parameters of the indoor fan, which may include on / off control parameters or speed control parameters of the indoor fan.

[0131] In this embodiment, when the position is the return air outlet of the indoor air duct, the indoor fan is controlled to run at a preset speed; when the position is a position outside the environment conditioning device in the indoor space, the indoor fan is controlled to be turned off. In this embodiment, the preset speed may be a minimum speed. In other embodiments, the preset speed may also be other speeds greater than the minimum speed.

[0132] In other embodiments, when the position is a first position outside the environment conditioning device in the indoor space, the indoor fan is controlled to run at a first speed or turned off; when the position is a second position outside the environment conditioning device in the indoor space, the indoor fan is controlled to run at a second speed. The distance between the first position and the environment conditioning device is smaller than the distance between the second position and the environment conditioning device. The first speed may be greater than the second speed.

[0133] Step S13: determining the indoor environment parameters according to the first data.

[0134] The first data may include indoor temperature data and / or indoor humidity data. The first data may be directly used as indoor environmental parameters, such as indoor temperature or indoor humidity, etc.; indoor environmental parameters, such as indoor dew point temperature, etc. may also be calculated through indoor temperature data and indoor humidity data.

[0135] Specifically, when the second indoor ambient temperature is greater than or equal to the outdoor ambient temperature, the first indoor ambient temperature is determined according to the first data; when the second indoor ambient temperature is less than the outdoor ambient temperature, the indoor dew point temperature is determined according to the first data.

[0136] In this embodiment, the operation of the indoor fan is regulated and controlled according to the position where the indoor parameter detection module is located, and the first data detected by the indoor parameter detection module is obtained during the operation of the indoor fan according to the parameters matching the first position to determine the indoor environmental parameters, thereby effectively avoiding the influence of the introduction of fresh air on the indoor environmental parameter detection results, improving the accurate characterization of the indoor environmental conditions by the obtained indoor environmental parameters, so as to further improve the accuracy of subsequent condensation risk identification, ensure the accurate regulation of the operation of the fresh air device, and further reduce the condensation risk of the environmental conditioning equipment. Among them, when the indoor parameter detection module is set at the return air outlet, the fresh air fan runs at a preset speed, which is conducive to promoting indoor air flow, avoiding the concentration of fresh air sent by the environmental conditioning equipment in the area where the environmental conditioning equipment is located, increasing the detection error of the indoor parameter detection module on the return air outlet, and improving the accuracy of the indoor environmental parameters detected by the indoor parameter detection module; when the indoor parameter detection module is set outside the environmental conditioning equipment, the fresh air fan is turned off, which can reduce the amount of fresh air blown to the area where the indoor parameter detection module can be located, reduce the detection error of the external indoor parameter detection module, and improve the accuracy of the indoor environmental parameters detected by the indoor parameter detection module.

[0137] Further, based on any of the above embodiments, another embodiment of the control method of the environmental conditioning device of the present application is proposed. Figure 7 The step of obtaining the fresh air parameters of the fresh air introduced by the fresh air device comprises:

[0138] Step S14, obtaining installation status information of the fresh air parameter detection module in the fresh air device;

[0139] The installation status information can be obtained by obtaining information input by the user, or by obtaining the model of the fresh air device, or by obtaining status information pre-stored in the fresh air device. Specifically, the fresh air fan can be controlled to run at a target speed and the wind speed in the fresh air duct can be detected. If the wind speed is greater than a preset threshold, the installation status information can be determined as the fresh air parameter detection module is not installed. If the wind speed is less than or equal to the preset threshold, the installation status information can be determined as the fresh air parameter detection module is installed.

[0140] Step S15, when the installation status information indicates that the fresh air parameter detection module has been installed, obtaining second data detected by the fresh air parameter detection module, and determining the fresh air parameter according to the second data;

[0141] The second data may include fresh air temperature data and / or fresh air humidity data. The second data may be directly used as fresh air parameters, such as fresh air temperature or fresh air humidity, etc.; the fresh air parameters may also be calculated by using the fresh air temperature data and the fresh air humidity data, such as the fresh air dew point temperature, etc.

[0142] Specifically, when the second indoor ambient temperature is greater than or equal to the outdoor ambient temperature, the first indoor ambient temperature is determined according to the first data; when the second indoor ambient temperature is less than the outdoor ambient temperature, the indoor dew point temperature is determined according to the first data.

[0143] Step S16: when the installation status information indicates that the fresh air parameter detection module is not installed, determining the fresh air parameters according to outdoor environmental parameters.

[0144] Specifically, the outdoor environmental parameters can be obtained by acquiring the parameters detected by the outdoor parameter detection module, or by acquiring weather data of the area where the environmental adjustment device is located based on the network.

[0145] Specifically, the result after correcting the outdoor environmental parameters according to the preset parameter values ​​can be used as the fresh air parameters. Further, in this embodiment, the target correction parameters can be determined according to the indoor environmental parameters, and the fresh air parameters can be obtained after correcting the outdoor environmental parameters according to the target correction parameters.

[0146] The outdoor environmental parameters include outdoor environmental temperature and / or outdoor environmental humidity. Specifically, the outdoor environmental parameters can be directly used as the fresh air parameters, or the fresh air parameters can be calculated through the outdoor environmental parameters.

[0147] In this embodiment, when the second indoor ambient temperature is greater than or equal to the outdoor ambient temperature, the above-mentioned fresh air dew point temperature is determined according to the second data; when the second indoor ambient temperature is lower than the outdoor ambient temperature, the above-mentioned fresh air temperature is determined according to the second data.

[0148] In this embodiment, different methods are adopted to obtain the fresh air parameters in accordance with the different installation states of the fresh air parameter detection module in the fresh air device, so that regardless of whether the fresh air parameter detection module is installed in the fresh air device, the fresh air parameters can be obtained for determining whether there is a condensation risk in the subsequent environmental conditioning equipment, thereby further avoiding condensation in the environmental conditioning equipment and ensuring that the environmental conditioning equipment can be used normally.

[0149] In addition, an embodiment of the present invention further proposes a storage medium, on which a control program of an environmental conditioning device is stored. When the control program of the environmental conditioning device is executed by a processor, the relevant steps of any embodiment of the control method of the environmental conditioning device as described above are implemented.
