The air handling device can be built into the fresh air fan (such as the heat pump system in the fresh air fan), or can be arranged independently of the fresh air fan (such as an air conditioner, etc.).

[0081] In the embodiment of the present invention, referring to Figure 1 , the control device 1 includes: a processor 1001, such as a CPU, a memory 1002, and a timer 1003. Among them, these components are connected and communicate through a communication bus. 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.

[0082] Those skilled in the art can understand that Figure 1 the device structure shown in does not constitute a limitation on the device, and it may include more or fewer components than shown in the figure, or combine some components, or arrange different components.

[0083] Such asFigure 1 As shown in Figure 1 , the memory 1002, which is a computer storage medium, may include a control program for the environmental control device.

[0084] In Figure 1 the device shown in Figure 1 , the processor 1001 may be used to call the control program for the environmental control device stored in the memory 1002 and execute the relevant step operations of the control method for the environmental control device in the following embodiments.

[0085] An embodiment of the present invention also provides a control method for an environmental control device, which is applied to the above-mentioned environmental control device.

[0086] Referring to Figure 2 , an embodiment of the control method for the environmental control device of the present application is proposed. In this embodiment, the control method for the environmental control device includes:

[0087] Step S10: Obtain the air state parameters of the indoor space;

[0088] The air state parameters include at least one of the following: pollutant concentration, temperature, humidity, oxygen concentration.

[0089] In this embodiment, when the environmental control device turns on the preset mode, step S10 here is executed. The preset mode here is set to adjust the air state of the indoor space.

[0090] Step S20: Determine the exhaust control parameters of the exhaust device according to the air state parameters;

[0091] The exhaust control parameters include at least one of the following parameters: target exhaust volume, opening duration of the exhaust device, fan speed in the exhaust device, exhaust volume adjustment value, etc.

[0092] The corresponding relationship between the air state parameters and the exhaust control parameters can be preset in advance. The corresponding relationship can include forms such as calculation formulas, mapping relationships, etc. Based on this corresponding relationship, the exhaust control parameters corresponding to each air state parameter can be determined.

[0093] Step S30: Control the operation of the exhaust device according to the exhaust control parameters.

[0094] In this embodiment, if the exhaust control parameters include the target exhaust volume, the exhaust device is controlled to operate at the target exhaust volume.

[0095] In the control method for the environmental control device proposed in the embodiment of the present invention, the exhaust control process of the exhaust device is no longer controlled according to the user's instructions, but can be automatically adjusted according to the indoor air state, so as to ensure that the exhaust volume matches the actual demand and improve the user comfort of the indoor space.

[0096] Further, based on the above embodiments, another embodiment of the control method of the environmental regulation device of the present application is proposed. In this embodiment, the air state parameters include pollutant concentration and characteristic parameters, and the characteristic parameters include temperature and / or humidity. Referring to Figure 3 , the step S20 includes:

[0097] Step S21, determining the exhaust air control parameter according to the pollutant concentration and the characteristic parameters.

[0098] The pollutant concentration may include at least one of the following: formaldehyde concentration, carbon dioxide concentration, nitrogen oxide concentration, carbon monoxide concentration, sulfur oxide, and so on.

[0099] The exhaust air control parameter is calculated by substituting the pollutant concentration and at least one of the temperature and humidity into a preset formula. Alternatively, a first control parameter is determined according to the pollutant concentration, a second control parameter is determined according to the temperature and / or humidity, and the exhaust air control parameter here is determined according to the first control parameter and the second control parameter.

[0100] In this embodiment, the pollutant concentration can accurately reflect the air quality of the corresponding indoor space, and the temperature and / or humidity can accurately reflect the temperature and humidity comfort level of the indoor space. Therefore, combining the air quality with the temperature and / or humidity to determine the exhaust air control parameter of the exhaust device in the space is beneficial to improving the air quality and temperature and humidity comfort of the space, thereby further improving the user comfort of the indoor space.

[0101] In this embodiment, the step of determining the exhaust air control parameter according to the pollutant concentration and the characteristic parameters includes: determining a first exhaust air volume according to the pollutant concentration; determining a second exhaust air volume according to the temperature and / or the humidity; determining a target exhaust air volume according to the first exhaust air volume and the second exhaust air volume, and the exhaust air control parameter includes the target exhaust air volume.

[0102] Substitute the pollutant concentration into the first formula to calculate the first exhaust air volume. Alternatively, the concentration range where the pollutant concentration is located can be determined, and the first exhaust air volume is determined according to the concentration range.

[0103] Substitute the temperature and / or humidity into the second formula to calculate the second exhaust air volume. Alternatively, the numerical range where the temperature and / or humidity is located can be determined, and the second exhaust air volume is determined according to the numerical range.

[0104] In this embodiment, the environmental regulation device further includes an air treatment device, and the air treatment device can refrigerate, heat, dehumidify and humidify, then:

[0105] In one implementation, when the air handling device is in the cooling mode, the second air discharge volume is determined according to the temperature, and the second air discharge volume is positively correlated with the temperature. For example, when the temperature is greater than the first preset temperature, the first air volume is determined as the second air discharge volume; when the temperature is less than or equal to the first preset temperature, the second air volume is determined as the second air discharge volume, and the first air volume is greater than the second air volume.

[0106] In one implementation, when the air handling device is in the heating mode, the second air discharge volume is determined according to the temperature, and the second air discharge volume is negatively correlated with the temperature. For example, when the temperature is less than the second preset temperature, the third air volume is determined as the second air discharge volume; when the temperature is greater than the second preset temperature, the fourth air volume is determined as the second air discharge volume, and the third air volume is greater than the fourth air volume.

[0107] In one implementation, when the air handling device is in the dehumidifying mode, the second air discharge volume is determined according to the humidity, and the second air discharge volume is positively correlated with the humidity. For example, when the humidity is greater than the first preset humidity, the fifth air volume is determined as the second air discharge volume; when the humidity is less than or equal to the first preset humidity, the sixth air volume is determined as the second air discharge volume, and the fifth air volume is greater than the sixth air volume.

[0108] When the air handling device is in the humidifying mode, the second air discharge volume is determined according to the humidity, and the second air discharge volume is negatively correlated with the humidity. For example, when the humidity is less than the second preset humidity, the seventh air volume is determined as the second air discharge volume; when the humidity is less than or equal to the second preset humidity, the eighth air volume is determined as the second air discharge volume, and the seventh air volume is greater than the eighth air volume.

[0109] In this embodiment, by the above method, it is ensured that the air discharge volume of the exhaust device can accurately meet the requirements of indoor air cleanliness and temperature and humidity comfort, and further improve the comfort of users in the indoor space.

[0110] Further, in this embodiment, the step of determining the target air discharge volume according to the first air discharge volume and the second air discharge volume includes: when at least one of the first air discharge volume and the second air discharge volume is equal to the first preset air discharge volume, determining the target air discharge volume as the first preset air discharge volume; when both the first air discharge volume and the second air discharge volume are equal to the second preset air discharge volume, determining the target air discharge volume as the second preset air discharge volume; wherein, the first preset air discharge volume is greater than the second preset air discharge volume.

[0111] In this embodiment, the air discharge volume represents the air speed gear of the exhaust device. The first preset air discharge volume and the second preset air discharge volume here respectively represent different air speed gears of the exhaust device. Among them, the first preset air discharge volume represents the high air speed gear, and the second preset air discharge volume represents the low air speed gear.

[0112] When at least one of the first row air volume and the second row air volume is at the high wind gear, the exhaust air control parameter is at the high wind gear; when both the first row air volume and the second row air volume are at the low wind gear, the exhaust air control parameter is at the low wind gear.

[0113] In this embodiment, through the above method, it is beneficial to ensure that the air quality state and the temperature and humidity state of each area of the indoor space can reach the comfortable range, thereby effectively improving the overall comfort of the indoor space.

[0114] In other embodiments, the first weight value and the second weight value corresponding to the first row air volume and the second row air volume can also be determined according to the operating parameters of the fresh air unit in the indoor space (such as the operating parameters of the heat pump subsystem in the fresh air unit, the operating parameters of the air supply fan, and the operating parameters of the exhaust air fan, etc.), and the target exhaust air volume is calculated by weighted average according to the first weight value and the corresponding first row air volume, and the second weight value and the corresponding second row air volume.

[0115] Further, in one embodiment, before the step of controlling the operation of the exhaust device according to the exhaust air control parameter, the control method of the environmental conditioning device further includes: determining the operating state of the environmental conditioning device; the step of determining the target exhaust air volume according to the first row air volume and the second row air volume includes: determining the target exhaust air volume according to the first row air volume, the second row air volume and the operating state. Among them, the step of determining the target exhaust air volume according to the first row air volume, the second row air volume and the operating state includes: when at least one of the first row air volume and the second row air volume is equal to the first preset exhaust air volume, and the operating state is in the preset operating state, determining that the target exhaust air volume is less than the first preset exhaust air volume; when both the first row air volume and the second row air volume are equal to the second preset exhaust air volume, and the operating state is in the preset operating state, determining the target exhaust air volume according to the type of the environmental conditioning device, where the target exhaust air volume is less than or equal to the second preset exhaust air volume.

[0116] The preset operating state here includes one of the following: the operating state when the environmental conditioning device operates in the moisture-proof mode, the operating state when the environmental conditioning device operates in the anti-condensation mode, and the operating state of the environmental conditioning device when there is a condensation risk in the indoor space.

[0117] In this embodiment, the environmental conditioning device is a fresh air unit, and the types of the environmental conditioning device include a unidirectional flow fresh air unit or a bidirectional flow fresh air unit.

[0118] In this embodiment, each row of air volume represents the wind gear of the exhaust device.

[0119] In this embodiment, when at least one of the first exhaust air volume and the second exhaust air volume is equal to the first preset exhaust air volume, and the operating state is in the preset operating state, the target exhaust air volume can be determined to be the second preset exhaust air volume, and the second preset exhaust air volume is less than the first preset exhaust air volume. In this embodiment, the second preset exhaust air volume is the minimum exhaust air volume. When both the first exhaust air volume and the second exhaust air volume are equal to the second preset exhaust air volume, and the operating state is in the preset operating state, when the environmental conditioning device is a two-way flow fresh air machine, the target exhaust air volume can be determined to be 0, that is, the exhaust device is closed; when the environmental conditioning device is a one-way flow fresh air machine, the target exhaust air volume can be determined to be the second preset exhaust air volume, that is, the exhaust device needs to maintain the open state.

[0120] In this embodiment, through the above method, when there is a risk of condensation in the indoor space or there is a need for anti-condensation, reducing the exhaust air volume through the exhaust device can effectively reduce the dew point temperature of the indoor space, thereby effectively reducing the risk of condensation in the indoor space. Among them, when the fresh air machine has an exhaust function, the method of reducing the exhaust air volume of the exhaust device is adopted to reduce the condensation risk; when the fresh air machine does not have an exhaust function, the method of closing the exhaust device is prohibited to reduce the condensation risk, so as to take into account the air quality and the comfort of indoor temperature and humidity while reducing the condensation risk in the indoor space.

[0121] 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, after the step S30, it further includes:

[0122] When there is a risk of condensation in the indoor space, control the exhaust device to reduce the exhaust air volume. After step S30, detect the condensation temperature of the indoor space and the wall temperature of the indoor space, and determine whether there is a risk of condensation in the indoor space according to the temperature difference value between the avoidance temperature and the condensation temperature.

[0123] Specifically, the exhaust device can be controlled to reduce the exhaust air volume according to a preset fixed air volume adjustment value. Alternatively, the air volume adjustment value can be determined according to the current state parameter (such as dew point temperature and wall temperature, etc.) representing the condensation risk size of the indoor space, and the exhaust device is controlled to reduce the exhaust air volume according to the air volume adjustment value.

[0124] In one implementation, when there is a risk of condensation in the indoor space and the fresh air device in the indoor space is a two-way flow fresh air device, control the exhaust device in the indoor space to reduce the exhaust air volume. Here, the air volume of the exhaust device after reducing the exhaust air volume can be 0, that is, the exhaust device is closed. Specifically, when the exhaust device is currently operating at a high air volume, control the exhaust device to reduce to a low air volume operation; when the exhaust device is currently operating at a low air volume, control the exhaust device to close.

[0125] In another implementation, when there is a risk of condensation in the indoor space and the fresh air unit in the indoor space is a unidirectional flow fresh air device, the exhaust device in the indoor space is controlled to reduce the exhaust air volume within an air volume range greater than or equal to the minimum exhaust air volume. Here, the minimum exhaust air volume is an air volume greater than 0. When the current exhaust air volume of the exhaust device is the minimum exhaust air volume, the exhaust device is controlled to maintain the minimum exhaust air volume operation; when the current exhaust air volume of the exhaust device is greater than the minimum exhaust air volume, the exhaust device is controlled to reduce to an air volume greater than or equal to the minimum exhaust air volume. Among them, when the current exhaust air volume of the exhaust device is the minimum exhaust air volume, while controlling the exhaust device to maintain the minimum exhaust air volume operation, other devices in the indoor space (such as the heat pump subsystem or radiant air conditioning in the fresh air device) can be controlled to adjust their operating parameters to reduce the risk of condensation in the indoor space.

[0126] In this embodiment, through the above method, reducing the exhaust air volume through the exhaust device can effectively reduce the dew point temperature of the indoor space, thereby effectively reducing the risk of condensation in the indoor space. Among them, when the fresh air unit has an exhaust function, the method of reducing the exhaust air volume of the exhaust device is adopted to reduce the risk of condensation; when the fresh air unit does not have an exhaust function, the method of closing the exhaust device is prohibited to reduce the risk of condensation, so as to take into account the air quality and the comfort of indoor temperature and humidity while reducing the risk of condensation in the indoor space.

[0127] Further, based on any of the above embodiments, another embodiment of the control method of the environmental conditioning equipment of the present application is proposed. In this embodiment, referring to Figure 5 , after the step S30, it further includes:

[0128] Step S40, when the pollutant concentration in the indoor space is greater than the preset concentration and the indoor space is provided with a bidirectional flow fresh air device, control the bidirectional flow fresh air device in the indoor space to supply air at a supply air volume greater than the first preset air volume, and control the bidirectional flow fresh air device in the indoor space to exhaust air according to the target exhaust control parameter, where the target exhaust control parameter is determined according to the current supply air volume of the bidirectional flow fresh air device in the indoor space and the exhaust air volume of the exhaust device in the indoor space.

[0129] In this embodiment, being greater than the first preset air volume specifically refers to the maximum supply air volume of the fresh air device. In other embodiments, the supply air volume for the fresh air device to supply air can also be determined according to the indoor pollutant concentration within an air volume range greater than the first preset air volume.

[0130] The target exhaust control parameter is the exhaust control parameter of the fresh air device required for the indoor space to reach a positive pressure state when both the fresh air device and the exhaust device are turned on.

[0131] The target exhaust control parameter may include at least one of the following: target exhaust air volume, exhaust adjustment amount, maximum exhaust air volume, minimum exhaust air volume.

[0132] In one implementation, the difference between the supply air volume and the exhaust air volume is determined as the reference exhaust air volume, and the reference exhaust air volume is reduced according to the first adjustment value to obtain the target exhaust air volume or the maximum exhaust air volume of the exhaust device.

[0133] In another implementation, the exhaust air volume is increased according to the second adjustment value to obtain the reference exhaust air volume, and the difference between the supply air volume and the reference exhaust air volume is used as the maximum exhaust air volume or the target exhaust air volume of the exhaust device.

[0134] In still another implementation, the supply air volume is reduced according to the third adjustment value to obtain the reference supply air volume, and the difference between the reference supply air volume and the exhaust air volume is used as the maximum exhaust air volume or the target exhaust air volume.

[0135] In this embodiment, through the above methods, it is beneficial to ensure the coordinated cooperation between the fresh air device and the exhaust device to ensure the positive pressure state in the room.

[0136] Further, in this embodiment, the target exhaust control parameter includes the maximum exhaust air volume. The step of determining the target exhaust control parameter according to the exhaust air volume of the exhaust device and the current supply air volume of the two-way fresh air device includes: reducing the supply air volume to obtain the reference supply air volume; determining the maximum exhaust air volume of the two-way fresh air device allowed for the indoor environment to reach the positive pressure state according to the difference between the reference supply air volume and the exhaust air volume of the exhaust device.

[0137] Here, the supply air volume can be reduced according to a preset fixed air volume adjustment value to obtain the reference supply air volume here, or the supply air volume can be reduced according to the air volume adjustment value determined according to the actual operating conditions. For example, it can be determined according to the number of newly opened air conditioners and / or the deviation value between the indoor air state parameter and the outdoor air state parameter, and / or, the deviation value between the current exhaust air volume of the two-way fresh air device and the maximum air volume of the exhaust device, and / or, the deviation value between the current exhaust air volume of the two-way fresh air device and the current supply air volume of the two-way fresh air device, etc. to determine the air volume adjustment value here.

[0138] After obtaining the maximum exhaust air volume, the step of controlling the exhaust operation of the two-way fresh air device in the indoor space according to the target exhaust control parameter includes: controlling the two-way fresh air device in the indoor space to exhaust at the maximum exhaust air volume.

[0139] In this embodiment, the maximum exhaust air volume of the two-way fresh air device is determined through the above method, so as to ensure that even when the exhaust system is turned on, the total exhaust air volume in the indoor space will not be too large, so as to further ensure that the indoor space can reach the positive pressure state.

[0140] In other embodiments, obtain the current target exhaust air volume of the fresh air device; when the target exhaust air volume is greater than or equal to the maximum exhaust air volume, control the fresh air device to operate at the maximum exhaust air volume; when the target exhaust air volume is less than the maximum exhaust air volume, control the fresh air device to operate at the target exhaust air volume. Here, the target exhaust air volume can be determined according to the actual requirements such as indoor air state parameters (such as at least one of indoor temperature, indoor humidity, indoor pollutant concentration, indoor enthalpy value, etc.) and / or outdoor air state parameters (such as at least one of outdoor temperature, outdoor humidity, outdoor pollutant concentration, outdoor enthalpy value, etc.) and / or user-set parameters (target parameters of the indoor environment set by the user) and / or state parameters of the heat pump system (such as at least one of the exhaust parameters, suction parameters of the compressor, refrigerant inlet and outlet temperatures of the heat exchanger in the fresh air duct, etc., which represent reliability risks and / or heat transfer efficiency parameters).

[0141] Further, based on any of the above embodiments, another optional embodiment of the control method of the environmental control device of the present application is proposed. In this embodiment, referring to Figure 5 , after the step S30, it further includes:

[0142] Step S50, when the air parameters in the indoor space meet the preset conditions and the indoor space is provided with a two-way fresh air device, control the two-way fresh air device in the indoor space to exhaust air at an exhaust air volume less than the second preset air volume, and control the two-way fresh air device in the indoor space to supply air according to the target fresh air control parameters, where the target fresh air control parameters are determined according to the current exhaust air volume of the two-way fresh air device in the indoor space and the exhaust air volume of the exhaust device in the indoor space; where the preset conditions include at least one of the following conditions: the indoor temperature is outside the comfortable temperature range, and the indoor humidity is outside the comfortable humidity range.

[0143] When the environmental control device is currently in the cooling mode, the temperature set less than or equal to the first preset temperature is the comfortable temperature range; when the environmental control device is currently in the heating mode, the temperature set greater than or equal to the second preset temperature is the comfortable temperature range; when the environmental control device is currently in the dehumidification mode, the humidity set less than or equal to the first preset humidity is the comfortable humidity range; when the environmental control device is currently in the humidification mode, the humidity set greater than or equal to the second preset humidity is the comfortable humidity range.

[0144] In this embodiment, the air volume less than the second preset air volume is the minimum exhaust air volume of the fresh air device. In other embodiments, the exhaust air volume for the fresh air device to supply air can also be determined according to the indoor pollutant concentration within the air volume range less than the second preset air volume.

[0145] The target fresh air control parameter is the fresh air control parameter of the fresh air device required for the indoor to reach a positive pressure state when both the fresh air device and the exhaust device are turned on.

[0146] The target fresh air control parameter may include at least one of the following: target fresh air volume, fresh air adjustment volume, maximum fresh air volume, minimum fresh air volume.

[0147] In one implementation, the sum of the current exhaust air volume of the fresh air device and the exhaust air volume of the exhaust device is determined as the total exhaust air volume, and the total exhaust air volume is increased to obtain the target fresh air volume or the minimum fresh air volume of the air supply device.

[0148] In another implementation, the current exhaust air volume of the fresh air device is increased according to the first adjustment value to obtain the first fresh air volume; the exhaust air volume of the exhaust device is increased according to the second adjustment value to obtain the second fresh air volume. The sum of the first fresh air volume and the second fresh air volume is determined as the target fresh air volume or the minimum fresh air volume of the air supply device.

[0149] In this embodiment, through the above method, it is beneficial to ensure the coordinated cooperation between the fresh air device and the exhaust device to ensure the indoor positive pressure state.

[0150] Furthermore, in this embodiment, the target fresh air control parameter includes the minimum air supply volume. In this embodiment, the reference air supply volume of the fresh air machine is determined according to the sum of the current exhaust air volume of the fresh air device and the exhaust air volume of the exhaust device; the reference air supply volume is increased to obtain the minimum air supply volume of the air supply device when the indoor space reaches a positive pressure state.

[0151] The reference air supply volume here is the air supply volume required for the fresh air machine to send air into the room when the indoor and outdoor air pressures are balanced. In one implementation, there is one fresh air machine, and the sum of the current exhaust air volume of the fresh air device and the exhaust air volume of the exhaust device is determined as the reference air supply volume, and the reference air supply volume is increased to obtain the corresponding minimum air supply volume of this fresh air machine. In another implementation, there are more than one fresh air machines, and the sum of the current exhaust air volume of the fresh air device and the exhaust air volume of the exhaust device is determined as the total exhaust air volume, the air volume weights corresponding to each exhaust system are obtained, and the reference air supply volume corresponding to each fresh air machine is determined according to each air volume weight and the total exhaust air volume, and the reference air supply volume corresponding to each fresh air machine is increased to obtain the corresponding minimum air supply volume of each fresh air machine.

[0152] The reference air supply volume here can be increased according to a preset fixed air volume adjustment value to obtain the minimum air supply volume here. It can also be increased according to the air volume adjustment value determined according to the actual operating conditions. For example, the air volume adjustment value here can be determined according to the number of fresh air machines turned on and / or the deviation value between the indoor air state parameter and the outdoor air state parameter and / or the deviation value between the third exhaust air volume and the maximum air volume of the exhaust machine, etc.

[0153] After obtaining the minimum supply air volume, the step of controlling the supply air operation of the two-way flow fresh air device in the indoor space according to the target fresh air control parameter includes: controlling the two-way flow fresh air device in the indoor space to supply air at the minimum supply air volume.

[0154] In this embodiment, the maximum fresh air volume of the supply air device is determined in the above manner, so as to ensure that the fresh air volume sent into the indoor space by the supply air device is not too small, so as to further ensure that the indoor space can reach a positive pressure state.

[0155] In other embodiments, obtain the current target supply air volume of the fresh air device; when the target supply air volume is greater than the minimum supply air volume, control the fresh air device to operate at the target supply air volume; when the target supply air volume is less than or equal to the minimum supply air volume, control the fresh air device to operate at the minimum supply air volume. Wherein, the target supply air volume here can be determined according to the actual requirements such as indoor air state parameters (such as at least one of indoor temperature, indoor humidity, indoor pollutant concentration, indoor enthalpy value, etc.) and / or outdoor air state parameters (such as at least one of outdoor temperature, outdoor humidity, outdoor pollutant concentration, outdoor enthalpy value, etc.) and / or user setting parameters (target parameters of the indoor environment set by the user) and / or state parameters of the heat pump system (at least one parameter indicating reliability risk and / or heat exchange efficiency such as exhaust parameters of the compressor, return air parameters, refrigerant inlet and outlet temperatures of the heat exchanger in the fresh air duct, etc.).

[0156] Further, based on any of the above embodiments, the environmental conditioning device includes at least two of the exhaust devices for adjusting at least two connected indoor spaces, and different exhaust devices are used to adjust different indoor spaces. The step of determining the exhaust control parameter of the corresponding exhaust device according to the air state parameter includes: determining the exhaust control parameter of the exhaust device corresponding to each indoor space according to each air state parameter; the step of controlling the operation of the exhaust device according to the exhaust control parameter includes: controlling the operation of the corresponding exhaust device according to each exhaust control parameter.

[0157] In this embodiment, an air state parameter is obtained for each indoor area.

[0158] Further, when the preset mode is started, the connection state between each indoor space can be obtained. When all indoor spaces are connected, step S10 is executed. When the indoor spaces are not connected, a prompt message is output to prompt the user to open the passage openings between the indoor spaces, or the barrier members on the passage openings between the indoor spaces are controlled to open.

[0159] The exhaust control parameter of each exhaust device is determined according to the air state parameter of the indoor area where it is located.

[0160] Among them, the corresponding relationships between the air state parameters and the exhaust control parameters corresponding to different indoor areas may be different. Specifically, the corresponding relationship for each indoor area may be determined according to the operating state of the fresh air unit in the corresponding indoor space and / or the opening degree of the passage opening used to communicate with other indoor spaces and / or the exhaust demand instruction input by the user, etc.

[0161] At least two indoor areas include a first indoor area and a second indoor area. A first exhaust device is arranged in the first indoor area, and a second exhaust device is arranged in the second indoor area. The exhaust control parameter corresponding to the first exhaust device is a first control parameter, and the exhaust control parameter corresponding to the second exhaust device is a second control parameter. Then, the first exhaust device is controlled to operate according to the first control parameter, and the second exhaust device is controlled to operate according to the second control parameter.

[0162] In this embodiment, the environmental conditioning equipment uses different exhaust devices to adjust the air in different indoor areas. The exhaust control parameters of each exhaust device in this method are no longer fixed parameters, but are determined according to the air state parameters of the corresponding indoor area. The difference in the exhaust air volume of each space can promote the circulation of air in each indoor area, enabling the air in each space to be adjusted not only by the exhaust device in its own space, but also by the air in other spaces, which is beneficial to the air quality balance in each space and can reach the user's comfortable state, thus effectively improving the overall comfort of different areas in the indoor space.

[0163] Furthermore, in this embodiment, the air state parameters include pollutant concentration and characteristic parameters, and the characteristic parameters include temperature and / or humidity. Determining the exhaust control parameter of the exhaust device corresponding to the indoor space according to each air state parameter includes: determining the corresponding exhaust control parameter according to the pollutant concentration and the characteristic parameters. The specific determination process of the exhaust control parameter corresponding to each indoor space can refer to the relevant implementation method of step S21 above, which will not be elaborated here.

[0164] In this embodiment, the exhaust control parameter of the exhaust device in the corresponding space is determined by combining air quality with temperature and / or humidity. When the temperature, humidity or cleanliness state of each indoor area is different, the corresponding exhaust device can operate with different exhaust air volumes. The air in the area that has reached the temperature and humidity or is clean can flow to the area that has not reached the temperature and humidity or is not clean, which is beneficial to improving the efficiency of the temperature, humidity and cleanliness of each area in the indoor space to reach the comfortable state, ensuring that the air quality of each area in the entire indoor space is balanced and within the user's comfortable range, and at the same time, the temperature and humidity of each area are balanced and within the user's comfortable range, thus effectively improving the overall comfort of the indoor space.
