[0060] An embodiment of the present invention proposes an environmental conditioning device.

[0061] In an embodiment of the present invention, refer to Figure 1, the environmental control device includes a control device 1, a fresh air system 2, and an exhaust air system 3. Both the fresh air system 2 and the exhaust air system 3 are used to adjust the air in the indoor space (here referring to the same indoor space). The indoor space here can be the whole house or a kitchen or a bathroom. Among them, when the indoor space is the whole house, the living room and the kitchen are connected through the door of the kitchen or the gap at the kitchen door, and the living room and the bathroom can also be connected through the door of the bathroom or the gap at the bathroom door.

The structures (outer casings) of the fresh air system 2 and the exhaust air system 3 are not directly connected; or, the fresh air system 2 and the exhaust air system 3 are installed at different positions in the indoor space.

[0062] In this embodiment, the fresh air system 2 may include one or more fresh air fans. When more than one fresh air system 2 adjusts the indoor space, different fresh air systems 2 can adjust different areas in the indoor space.

[0063] In this embodiment, the fresh air fans in the fresh air system 2 are two-way flow fresh air fans or one-way flow fresh air fans. Among them, the two-way flow fresh air fan includes a air supply device 21 and an exhaust device 22. In this embodiment, the two-way flow fresh air fan is an integrated fresh air machine, and the air supply device 21 and the exhaust device 22 are of an integrated structure.

The first heat exchanger is in the evaporation state, and the second heat exchanger is in the condensation state. Among them, when there is a commutation component, the commutation component operates in the second state.

[0070] Furthermore, the number of heat pump devices 23 in the fresh air system 2 can be more than one. At least two heat exchangers corresponding to different heat pump devices 23 are arranged in the fresh air duct. The more than one heat exchanger can be arranged along the air flow direction of the fresh air duct or along a direction intersecting the air flow direction of the fresh air duct.

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.

[0073] Those skilled in the art can understand that Figure 1 the device structure shown in

[0074] such as Figure 1 does not constitute a limitation on the device, and it can include more or fewer components than shown in the figure, or combine some components, or have different component arrangements.

[0075] In Figure 1 the device shown, the processor 1001 can be used to call the control program of the environmental control device stored in the memory 1002 and execute the relevant step operations of the control method of the environmental control device in the following embodiments.

[0076] An embodiment of the present invention further provides a control method for an environmental conditioning device, which is applied to the above environmental conditioning device.

[0077] Referring to Figure 2 , an embodiment of the control method for the environmental conditioning device of the present application is proposed. In this embodiment, the fresh air system may include a two-way fresh air fan. Alternatively, the fresh air system may include at least two fans, and at least one of the at least two fans is a two-way fresh air fan. In this embodiment, the control method of the environmental conditioning device includes:

[0078] Step S10, control the fresh air system and the exhaust system to operate, and obtain the exhaust state parameters of the exhaust system and the fresh air system, and the fresh air state parameters of the fresh air system;

[0079] Here, the operation of the fresh air system and the exhaust system means that both the fresh air system and the exhaust system are in the on state. The operation parameters during the operation of the fresh air system and / or the exhaust system can be pre-set fixed parameters, or can be parameters determined according to the actual operating conditions of the environmental conditioning device or the user-set parameters. In this embodiment, the air state parameters for adjusting the indoor space by the environmental conditioning device are obtained, and the fresh air system and the exhaust system are respectively controlled to operate according to the air state parameters. The air state parameters include at least one of the following: temperature, humidity, pollutant concentration, etc. Specifically, the fresh air volume of the fresh air system can be determined according to the air state parameters, and the fresh air system is controlled to operate according to the fresh air volume. The exhaust volume of the exhaust system is determined according to the air state parameters, and the exhaust system is controlled to operate according to the exhaust volume. For example, the temperature difference value from the set temperature can be determined. When the temperature difference value is greater than the first temperature difference value, the exhaust system operates at a high air volume; otherwise, the exhaust system operates at a low air volume. Or, when the pollutant concentration is greater than the first preset concentration, the exhaust system operates at a high air volume; otherwise, the exhaust system operates at a low air volume. Also, for example, the temperature difference value from the set temperature can be determined. When the temperature difference value is greater than the second temperature difference value, the fresh air system operates at a high fresh air volume; otherwise, the fresh air system operates at a low fresh air volume. Or, when the pollutant concentration is greater than the second preset concentration, the fresh air system operates at a high fresh air volume; otherwise, the fresh air system operates at a low fresh air volume.

[0080] The exhaust state parameters may include the total exhaust air volume of the exhaust system and the fresh air system, or the exhaust air volume of the exhaust system and the fresh air system respectively, or the fan speeds of the exhaust system and the fresh air system respectively for exhausting air, etc.

[0081] The fresh air state parameters may include the total fresh air volume of the fresh air system, or the fresh air volume of each fresh air fan in the fresh air system, or the fan speeds of each fan for supplying fresh air in the fresh air system, etc.

[0082] The exhaust air state parameters here can be determined according to the current operating parameters related to exhaust air of the exhaust air system and the fresh air system (such as the rotational speed of the exhaust air fan and / or the opening degree of the exhaust air valve, etc.) and / or the theoretical exhaust air parameters (theoretical exhaust air volume and / or the theoretical rotational speed of the exhaust air fan, etc.). The fresh air state parameters can be determined according to the current operating parameters related to supplying fresh air of the fresh air system (such as the rotational speed of the fresh air fan and / or the opening degree of the fresh air valve, etc.).

[0083] Step S20: Determine the fresh air control parameters of the air supply device and the exhaust air control parameters of the exhaust air device according to the fresh air state parameters and the exhaust air state parameters;

[0084] The fresh air control parameters may include at least one of the following: target fresh air volume, fresh air adjustment amount, maximum fresh air volume, minimum fresh air volume, target air supply rotational speed, fan rotational speed adjustment value, maximum air supply rotational speed, minimum air supply rotational speed. In this embodiment, the fresh air control parameter includes the minimum fresh air volume of the air supply device.

[0085] The exhaust air control parameters may include at least one of the following: target exhaust air volume, exhaust air adjustment amount, maximum exhaust air volume, minimum exhaust air volume, target exhaust air rotational speed, fan rotational speed adjustment value, maximum exhaust air rotational speed, minimum exhaust air rotational speed. In this embodiment, the exhaust air control parameter includes the maximum exhaust air volume of the exhaust air device.

[0086] In one implementation, the fresh air control parameters can be determined by combining the fresh air state parameters and the exhaust air state parameters, and the exhaust air control parameters can be determined by combining the fresh air state parameters and the exhaust air state parameters. In another implementation, the fresh air control parameters can be determined according to the exhaust air state parameters, and the exhaust air control parameters can be determined by combining the exhaust air state parameters and the fresh air state parameters.

[0087] When the fresh air system includes more than one air supply device and at least one exhaust air device, the fresh air control parameters of each air supply device and the exhaust air control parameters of each exhaust air device can be determined according to the fresh air state parameters and the exhaust air state parameters.

[0088] Step S30: Control the operation of the air supply device according to the fresh air control parameters, and control the operation of the exhaust air device according to the exhaust air control parameters.

[0089] In this embodiment, the fresh air control parameter includes the minimum fresh air volume, and the air supply device can be controlled to operate with a fresh air volume greater than or equal to the minimum fresh air volume. The exhaust air control parameter includes the maximum exhaust air volume of the exhaust air device, and the exhaust air device is controlled to operate with an exhaust air volume less than or equal to the maximum exhaust air volume.

[0090] In other implementations, the fresh air control parameter may include the target fresh air volume, and the air supply device can be controlled to operate with the target fresh air volume; the exhaust air control parameter includes the target exhaust air volume, and the exhaust air device can be controlled to operate with the target exhaust air volume.

[0091] A control method for an environmental conditioning device proposed in an embodiment of the present invention. During the operation of both the fresh air system and the exhaust air system, the fresh air supply and exhaust of the fresh air system are controlled according to the exhaust state parameters of the exhaust air system and the fresh air system and the fresh air state parameters of the fresh air system, realizing the interlocking operation of the exhaust air system and the fresh air system, effectively avoiding insufficient fresh air volume when the fresh air system and the exhaust air system are turned on simultaneously, effectively ensuring that the indoor space adjusted by the environmental conditioning device can reach a positive pressure state, reducing the entry of outdoor air into the room and affecting the indoor environment, so as to effectively improve the indoor air quality.

[0092] Further, based on the above embodiment, another embodiment of the control method for the environmental conditioning device of the present application is proposed. In this embodiment, the exhaust state parameters include the first exhaust air volume of the exhaust air system and the second exhaust air volume of the exhaust device, and the fresh air state parameters include the fresh air volume of the air supply device. Referring to Figure 3 the step of determining the fresh air control parameter of the air supply device and the exhaust control parameter of the exhaust device according to the fresh air state parameter and the exhaust state parameter includes:

[0093] Step S21, determining the minimum fresh air volume of the air supply device according to the first exhaust air volume and the second exhaust air volume;

[0094] In one implementation, the sum of the first exhaust air volume and the second exhaust air volume is determined as the total exhaust air volume, and the total exhaust air volume is increased to obtain the minimum fresh air volume of the air supply device.

[0095] In another implementation, the first exhaust air volume is increased according to a first adjustment value to obtain a first fresh air volume; the second exhaust air volume is increased according to a second adjustment value to obtain a second fresh air volume. The sum of the first fresh air volume and the second fresh air volume is determined as the minimum fresh air volume of the air supply device.

[0096] Step S22, determining the maximum exhaust air volume of the exhaust device according to the first exhaust air volume and the fresh air volume.

[0097] In one implementation, the difference between the fresh air volume and the first exhaust air volume is determined as the reference exhaust air volume, and the reference exhaust air volume is reduced according to a third adjustment value to obtain the maximum exhaust air volume of the exhaust device.

[0098] In another implementation, the first exhaust air volume is increased according to a fourth adjustment value to obtain the first exhaust air volume, and the difference between the fresh air volume and the first exhaust air volume is used as the maximum exhaust air volume of the exhaust device.

[0099] In yet another implementation, the fresh air volume is reduced according to a fifth adjustment value to obtain a reference fresh air volume, and the difference between the reference fresh air volume and the first exhaust air volume is the maximum exhaust air volume.

[0100] In this embodiment, through the above method, it is possible to ensure that the air supply volume of the fresh air system is not too small and the exhaust air volume of the exhaust air system is not too large, which is conducive to ensuring the coordinated cooperation between the fresh air system and the exhaust air system to ensure that the indoor positive pressure state can be achieved.

[0101] In other embodiments, when there are more than one air supply devices, the first exhaust air volume may be the total exhaust air volume of the exhaust air system. Based on this, the total exhaust air volume of the indoor space adjusted by the environmental control device is determined according to the sum of the first exhaust air volume and the second exhaust air volumes of all the exhaust air devices in the fresh air system. The total air supply volume of the more than one air supply devices is determined according to the total exhaust air volume, and the fresh air control parameters of each air supply device are determined according to the total air supply volume. When there are more than one exhaust air devices, the first exhaust air volume is the total exhaust air volume of the exhaust air system. The total exhaust air volume of all the exhaust air devices is determined according to the sum of the fresh air volumes of all the air supply devices and the first exhaust air volume, and the exhaust air control parameters of each exhaust air device are determined according to the total exhaust air volume.

[0102] Further, in this embodiment, the second exhaust air volume includes the minimum exhaust air volume of the exhaust air device set in advance. Here, the minimum exhaust air volume can be a fixed value set in advance or a value determined according to the actual operating state of the fresh air machine where the exhaust air device is located. Specifically, the second heat exchanger can be arranged in the exhaust air duct. During the operation of the heat pump system, the minimum exhaust air volume here can be obtained according to the state parameters of the heat pump device, so as to ensure the reliable operation of the heat pump system. Determining the minimum fresh air volume of the air supply device according to the first exhaust air volume and the second exhaust air volume includes: determining the minimum fresh air volume of the air supply device according to the first exhaust air volume and the minimum exhaust air volume. In this embodiment, the reference fresh air volume of the fresh air machine is determined according to the sum of the first exhaust air volume and the minimum exhaust air volume; the reference fresh air volume is increased to obtain the minimum fresh air volume of the air supply device when the indoor space reaches the positive pressure state.

[0103] The reference fresh air volume here is the fresh air volume that the fresh air machine needs to send into the room when the indoor and outdoor air pressures are balanced. In one implementation, when there is one fresh air machine, the sum value of the first exhaust air volume and the second exhaust air volume is determined as the reference fresh air volume, and the reference fresh air volume is increased to obtain the corresponding minimum fresh air volume of this fresh air machine. In another implementation, when there are more than one fresh air machines, the sum value of the first exhaust air volume and the second exhaust air volume is determined as the total exhaust air volume, the air volume weights corresponding to each exhaust air system are obtained, the reference fresh air volume corresponding to each fresh air machine is determined according to each air volume weight and the total exhaust air volume, and the reference fresh air volume corresponding to each fresh air machine is increased to obtain the corresponding minimum fresh air volume of each fresh air machine.

[0104] The reference fresh air volume here can be increased according to a preset fixed air volume adjustment value to obtain the minimum fresh air volume here. For example, if the air volume of the first row is 100 cubic meters, the air volume of the second row is 240 cubic meters, and the fixed air volume adjustment value is 1.25, then the minimum fresh air volume is (100 + 240) * 1.25 = 425 cubic meters. Alternatively, the reference fresh air volume can also be increased according to the air volume adjustment value determined based on the actual operating conditions. For example, the air volume adjustment value here can be determined according to the number of operating fresh air machines and / or the deviation value between the indoor air state parameters and the outdoor air state parameters and / or the deviation value between the air volume of the first row and the maximum air volume of the exhaust machine, etc.

[0105] In this embodiment, the minimum fresh air volume of the air supply device is determined in the above manner, so as to ensure that the fresh air volume sent into the indoor space by the air supply device is not too small, so as to further ensure that the indoor space can reach a positive pressure state.

[0106] In other embodiments, the air volume of the second row can also be the actual exhaust air volume of the exhaust device.

[0107] Further, in this embodiment, the step of determining the exhaust control parameter according to the air volume of the first row and the fresh air volume includes: reducing the fresh air volume to obtain a reference fresh air volume; determining the maximum exhaust air volume of the exhaust device according to the reference fresh air volume and the air volume of the first row, and the exhaust control parameter includes the maximum exhaust air volume.

[0108] The fresh air volume here can be reduced according to a preset fixed air volume adjustment value to obtain the reference fresh air volume here, or the fresh air volume can also be reduced according to the air volume adjustment value determined based on the actual operating conditions. For example, the air volume adjustment value here can be determined according to the number of operating fresh air machines and / or the deviation value between the indoor air state parameters and the outdoor air state parameters and / or the deviation value between the air volume of the first row and the maximum air volume of the exhaust machine and / or the deviation value between the current exhaust air volume of the exhaust device and the current fresh air volume of the air supply device, etc.

[0109] When the fresh air system includes one fresh air machine and both the air supply device and the exhaust device are one, the difference between the reference fresh air volume and the air volume of the first row can be determined as the maximum exhaust air volume of the exhaust device.

[0110] When the fresh air system includes more than one fresh air machine, the maximum exhaust air volume of the exhaust device can be determined according to the difference between the sum of all reference fresh air volumes and the air volume of the first row.

[0111] For example, if the fresh air volume is 450 cubic meters and the air volume of the first row is 100 cubic meters, then the maximum exhaust air volume is 450 * 0.8 - 100 = 260 cubic meters.

[0112] In this embodiment, the maximum exhaust air volume of the exhaust device is determined in the above manner, so as to ensure that even when the exhaust system is turned on, the total exhaust air volume of the indoor space will not be too large, so as to further ensure that the indoor space can reach a positive pressure state.

[0113] Further, in this embodiment, the fresh air system includes at least two two-way fresh air fans, and the two-way fresh air fan includes the air supply device and the exhaust device. Among them, different indoor areas in the indoor space adjusted by the environmental conditioning equipment can be adjusted by different fresh air fans in the fresh air system. The step of determining the minimum fresh air volume according to the first exhaust air volume and the second exhaust air volume includes: determining the reference exhaust air volume of each two-way fresh air fan according to the first exhaust air volume and the rated air volume of each two-way fresh air fan; determining the minimum fresh air volume of each air supply device according to the reference exhaust air volume corresponding to each two-way fresh air fan and the second exhaust air volume.

[0114] The rated air volume is specifically the maximum air volume that the fresh air fan allows to output under rated working conditions. The rated air volume can be obtained by acquiring the parameters pre-stored in the system.

[0115] Determine the weight corresponding to each two-way fresh air fan according to the rated air volume of each two-way fresh air fan, and determine the reference exhaust air volume of each two-way fresh air fan according to the first exhaust air volume and the corresponding weight.

[0116] The reference exhaust air volume here is the exhaust air volume of the exhaust system that each two-way fresh air fan needs to bear when the indoor space reaches positive pressure during the fresh air supply process, and can also be understood as the fresh air volume that the two-way fresh air fan needs to provide.

[0117] In this embodiment, determine the sum of all the rated air volumes, and determine the relationship value between each rated air volume and the sum; determine the reference exhaust air volume of each two-way fresh air fan according to the relationship value and the first exhaust air volume. The relationship value may include a ratio or a difference. In this embodiment, determine the ratio of the rated air volume to the sum as the relationship value, and take the product of the ratio and the first exhaust air volume as the reference exhaust air volume.

[0118] In this embodiment, the total exhaust air volume of each two-way fresh air fan can be determined according to the sum value of the reference exhaust air volume and the second exhaust air volume. The total exhaust air volume here is specifically the total exhaust air volume that each two-way fresh air fan needs to bear in the overall exhaust air volume of the indoor space when the indoor space and the outdoor environment reach pressure balance during the fresh air supply process. Here, the total exhaust air volume can be increased according to the fixed air volume adjustment value set in advance to obtain the minimum fresh air volume here. It is also possible to increase the total exhaust air volume according to the air volume adjustment value determined according to the actual operating conditions. For example, the air volume adjustment value can be determined according to the number of fresh air fans 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 first exhaust air volume and the maximum air volume of the exhaust machine, etc.

[0119] In this embodiment, through the above method, when adjusting the indoor space by more than one two-way flow fresh air machine, the exhaust air volume required to achieve positive pressure indoors can be allocated according to the output capacity of each two-way flow fresh air machine, so as to formulate the minimum fresh air volume of each two-way flow fresh air machine. On the basis of ensuring that the energy efficiency of the operation of each two-way flow fresh air machine can be effectively improved, ensure that each two-way flow fresh air machine can operate in coordination to ensure that the indoor space can reach the required positive pressure state.

[0120] In other embodiments, the sum of the first exhaust air volume and the second exhaust air volume can also be determined, and the sum is increased to obtain the minimum fresh air volume corresponding to the entire indoor space. According to each relationship value corresponding to the minimum fresh air volume, the minimum fresh air volume of each fresh air machine is determined. For example, if the relationship value is a ratio, the product of the minimum fresh air volume and the ratio corresponding to the fresh air machine is the minimum fresh air volume corresponding to each fresh air machine.

[0121] Further, in this embodiment, the fresh air control parameter includes the minimum fresh air volume of the air supply device. The step of controlling the air supply device to operate with a fresh air volume greater than or equal to the minimum fresh air volume includes: obtaining the air state parameters of the indoor space adjusted by the environmental control device; determining the required fresh air volume of the air supply device according to the air state parameters; when the required fresh air volume is less than the minimum fresh air volume, controlling the air supply device to operate with the minimum fresh air volume; when the required fresh air volume is greater than or equal to the minimum fresh air volume, or, when the required fresh air volume is greater than or equal to the minimum fresh air volume and less than the maximum fresh air volume of the air supply device, controlling the air supply device to operate with the required fresh air volume; or, when the required fresh air volume is greater than or equal to the maximum fresh air volume, controlling the air supply device to operate with the maximum fresh air volume; wherein, the minimum fresh air volume is less than the maximum fresh air volume.

[0122] The maximum fresh air volume is specifically the maximum value of the fresh air volume allowed to be sent into the room during the operation of the pre-set air supply device. The air supply devices in different fresh air machines can correspond to different maximum fresh air volumes.

[0123] The air state parameters may include at least one of the following: indoor temperature, indoor humidity, indoor pollutant concentration (such as carbon dioxide concentration or formaldehyde concentration, etc.), and so on. Different air state parameters correspond to different required fresh air volumes. Specifically, the required fresh air volume corresponding to the air state parameters can be determined by calculation, looking up tables, etc. For example, the required fresh air volume is positively correlated with the indoor pollutant concentration.

[0124] For example, if the minimum fresh air volume is 425 cubic meters and the maximum fresh air volume is 500 cubic meters, when the required fresh air volume is 300 cubic meters, the air supply device can be controlled to operate at 425 cubic meters to ensure indoor positive pressure; when the required fresh air volume is 450 cubic meters, the air supply device can be controlled to operate at 450 cubic meters.

[0125] In this embodiment, through the above method, it is beneficial to ensure that under the control of the minimum fresh air volume, the fresh air volume input into the room by the fresh air system will not be too small, so as to effectively ensure the positive pressure state in the room.

[0126] Furthermore, in this embodiment, the exhaust air control parameter includes the maximum exhaust air volume of the exhaust air device, and the step of controlling the exhaust air device to operate at an exhaust air volume less than or equal to the maximum exhaust air volume includes: determining the required exhaust air volume of the exhaust air device according to the air supply volume of the air supply device; when the required exhaust air volume is greater than or equal to the maximum exhaust air volume, controlling the exhaust air device to operate at the maximum exhaust air volume; when the required exhaust air volume is less than the maximum exhaust air volume, or when the required exhaust air volume is less than the maximum exhaust air volume and greater than the minimum exhaust air volume, controlling the exhaust air device to operate at the required exhaust air volume; or when the required exhaust air volume is less than or equal to the minimum exhaust air volume, controlling the exhaust air device to operate at the minimum exhaust air volume; wherein, the minimum exhaust air volume is greater than the maximum exhaust air volume.

[0127] The minimum exhaust air volume is specifically the minimum air volume that the exhaust air device is allowed to exhaust outdoors as pre-set. The exhaust air devices in different fresh air machines may correspond to different minimum exhaust air volumes.

[0128] The required exhaust air volume of the exhaust air device can be determined according to the air supply volume of the air supply device in the same fresh air machine. The air supply volume here is specifically the fresh air volume currently introduced into the indoor space by the air supply device. Alternatively, the required exhaust air volume of each exhaust air device can also be determined according to the air supply volumes of all air supply devices in the fresh air system.

[0129] For example, if the maximum exhaust air volume is 260 cubic meters and the minimum exhaust air volume is 240 cubic meters, when the required exhaust air volume is 450 cubic meters, the air supply device can be controlled to operate at 260 cubic meters to ensure positive pressure in the room; when the required exhaust air volume is 240 cubic meters, the air supply device can be controlled to operate at 240 cubic meters.

[0130] In this embodiment, through the above method, it is beneficial to ensure that under the control of the maximum exhaust air volume, the total exhaust air volume of the exhaust air system will not be too large, so as to effectively ensure the positive pressure state in the room.

[0131] Furthermore, 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 4 , the control method of the environmental conditioning equipment further includes:

[0132] Step S40, determining the upper limit value of the air volume of the exhaust air system according to the air change capacity parameter of the fresh air system;

[0133] The upper limit value of the air volume is specifically the maximum exhaust air volume allowed by the exhaust air system.

[0134] In this embodiment, the ventilation capacity parameters include the maximum fresh air volume of the air supply device in the fresh air system and the minimum exhaust air volume of the exhaust fan in the fresh air system.

[0135] In one implementation, the maximum fresh air volume can be reduced according to the first air volume adjustment value to obtain the first air volume, and the upper limit value of the air volume can be determined according to the air volume difference between the first air volume and the minimum exhaust air volume.

[0136] In another implementation, the minimum exhaust air volume can be increased according to the second air volume adjustment value to obtain the second air volume, and the upper limit value of the air volume can be determined according to the air volume difference between the maximum fresh air volume and the second air volume.

[0137] In yet another implementation, the maximum fresh air volume can be reduced according to the third air volume adjustment value to obtain the third air volume, the minimum exhaust air volume can be increased according to the fourth air volume adjustment value to obtain the fourth air volume, and the upper limit value of the air volume can be determined according to the air volume difference between the third air volume and the fourth air volume.

[0138] Step S50: When the current total exhaust air volume of the exhaust system is greater than the upper limit value of the air volume, control the exhaust system to reduce the exhaust air volume.

[0139] The exhaust system reducing the exhaust air volume can include at least one of the following methods: turning off the exhaust fan or reducing the exhaust air volume of the exhaust fan (reducing the fan speed or decreasing the opening of the exhaust air valve, etc.).

[0140] In this embodiment, the exhaust system includes at least two exhaust fans, and the step of controlling the exhaust system to reduce the exhaust air volume includes: controlling at least one of the exhaust fans to shut down or reduce the exhaust air volume.

[0141] In this embodiment, restricting the total air volume of the exhaust system based on the ventilation capacity parameters of the fresh air system is beneficial to further ensure that the indoor space can reach a positive pressure state.

[0142] Furthermore, in this embodiment, the exhaust fan to be shut down is defined as the target exhaust fan, and the step of controlling at least one of the exhaust fans to shut down includes: controlling at least two of the target exhaust fans to shut down in sequence until the total exhaust air volume of the exhaust system is less than the upper limit value of the air volume.

[0143] Control one of the target exhaust fans to shut down, and after shutdown, determine whether the total exhaust air volume of the exhaust system is less than the upper limit value of the air volume. If not, continue to control the next target exhaust fan to shut down. If so, stop shutting down the exhaust fan.

[0144] Among them, two adjacent target exhaust fans can be shut down at intervals of a preset fixed duration, or at intervals of an unfixed duration.

[0145] In this embodiment, at least two target exhaust fans are shut down in sequence until the total exhaust air volume of the exhaust system is less than the upper limit of the air volume, so as to avoid unnecessary shutdown of the exhaust fans, ensure that the indoor space can reach positive pressure while meeting the indoor exhaust requirements.

[0146] Further, in this embodiment, the step of controlling at least two target exhaust fans to be shut down in sequence until the indoor space meets the preset positive pressure condition includes: obtaining the air state parameters of the adjustment area of each target exhaust fan and / or the operating state parameters of each target exhaust fan; determining the target exhaust fan with the highest shutdown priority according to the air state parameters and / or the operating state parameters, and controlling the target exhaust fan with the highest shutdown priority to be shut down; returning to execute the step of obtaining the air state parameters of the adjustment area of each target exhaust fan and / or the operating state parameters of each target exhaust fan until the indoor space meets the preset positive pressure condition.

[0147] The air state parameters include at least one of the following: pollutant concentration (such as carbon dioxide concentration, formaldehyde concentration, particulate matter concentration, etc.), regional temperature, regional humidity, regional enthalpy value, etc.

[0148] The operating state parameters include at least one of the following: on-off state, service life duration, continuous operation duration, etc.

[0149] In one implementation manner, the parameter interval where the air state parameters and / or the operating state parameters are located can be determined, and the shutdown priority is determined according to the parameter interval. In another implementation manner, the air state parameters and / or the operating state parameters can be substituted into a preset formula for calculation to obtain the shutdown priority. In yet another implementation manner, the evaluation values corresponding to each parameter in the air state parameters and / or the operating state parameters corresponding to each exhaust fan can be determined, and the shutdown priority of the corresponding exhaust fan is determined according to the sum of all the evaluation values.

[0150] In this embodiment, the air state parameters include pollutant concentration and / or regional temperature and / or regional humidity; the shutdown priority is negatively correlated with the pollutant concentration, the temperature difference value between the regional temperature and the corresponding comfortable temperature is negatively correlated with the shutdown priority, and the humidity difference value between the regional humidity and the corresponding set humidity is negatively correlated with the shutdown priority.

[0151] In this embodiment, the operating state parameter includes the on-off state of the corresponding controller, the on-off state includes an on state or an off state, and the shutdown priority corresponding to the on state is lower than the shutdown priority corresponding to the off state. Here, the controller can be a line controller connected to the exhaust fan in the indoor space.

[0152] For example, in the cooling mode, the comfortable temperature is 16 degrees. If it is defined that the lower the importance value, the higher the shutdown priority, then the temperatures of different regions and the importance values are as shown in the following table:

[0153] Regional temperature (°C) (16，18] (18，20] (20，22] (22，+∞) Importance value 8 6 4 2

[0154] Another example, in the heating mode, the comfortable temperature is 24 degrees. If it is defined that the lower the importance value, the higher the shutdown priority, then the temperatures of different regions and the importance integrals are as shown in the following table:

[0155] Regional temperature (°C) (24，26] (26，28] (28，30] (30，+∞) Importance value 2 4 6 8

[0156] Still another example, if it is defined that the lower the importance value, the higher the shutdown priority, then the importance value of the controller in the on state is 10 points, and the importance value of the controller in the off state is 0 points.

[0157] In this embodiment, shutting down the exhaust fan with the highest priority one by one, that is, the exhaust fan with the smallest exhaust demand in all spaces, is beneficial to maximizing the satisfaction of the exhaust demands of different regions, ensuring the normal use of the exhaust fan, and at the same time ensuring that the indoor space can reach a positive pressure state.

[0158] 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, the fresh air system further includes a heat pump device, which can control the heat pump device to be turned on during the opening process of the air supply device and the exhaust device to adjust the fresh air flowing through the air supply device, and obtain the fresh air inlet temperature, fresh air outlet temperature of the air supply device, and indoor inlet temperature of the exhaust device; determine the target corresponding relationship between the fresh air state parameters, exhaust state parameters, fresh air control parameters, and exhaust control parameters according to the fresh air inlet temperature, fresh air outlet temperature, and indoor inlet temperature; the step of determining the fresh air control parameters of the air supply device and the exhaust control parameters of the exhaust device according to the fresh air state parameters and the exhaust state parameters includes: determining the fresh air control parameters and the exhaust control parameters corresponding to the fresh air state parameters and the exhaust state parameters according to the target corresponding relationship.

[0159] Specifically, the first temperature difference value between the fresh air inlet temperature and the fresh air outlet temperature can be determined, the second temperature difference value between the fresh air inlet temperature and the indoor inlet temperature can be determined, and the target corresponding relationship here can be obtained according to the first temperature difference value and the second temperature difference value.

[0160] In this embodiment, through the above method, it is beneficial to reduce the influence of the indoor temperature fluctuation during the fresh air replacement process on the air pressure, and further ensure that the indoor space can accurately reach the target positive pressure state.

[0161] In addition, an embodiment of the present invention further provides a storage medium, on which a control program for an environmental adjustment device is stored.
