[0063] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0064] An embodiment of the present invention provides an environmental conditioning device.

[0065] In an embodiment of the present invention, referring to Figure 1 , the environmental conditioning device includes a control device 1, a fresh air machine 2, and an exhaust system 3. Both the fresh air machine 2 and the exhaust system 3 are used to condition the air in the indoor space (here referring to the same indoor space). The indoor space here can be the entire house or a kitchen or a bathroom. Among them, when the indoor space is the entire 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. Both the fresh air machine 2 and the exhaust system 3 are connected to the control device 1. The structures (outer casings) of the fresh air machine 2 and the exhaust system 3 are not directly connected; or, the fresh air machine 2 and the exhaust system 3 are installed at different positions in the indoor space.

[0066] In this embodiment, the number of fresh air machines 2 can be one or more than one. When multiple fresh air machines 2 condition the indoor space, different fresh air machines 2 condition different areas in the indoor space.

[0067] In this embodiment, the fresh air machine 2 is a two-way flow fresh air machine, and the fresh air machine 2 includes a air supply device 21 and an exhaust device 22.

[0068] In this embodiment, the fresh air machine 2 is an integrated fresh air machine, and the air supply device 21 and the exhaust device 22 are of an integrated structure.

[0069] The air supply device 21 may include a fresh air duct and a first fan provided in the fresh air duct. The fresh air duct communicates the indoor space with the outdoor environment. When the first fan is turned on, it can drive outdoor fresh air into the room.

[0070] The exhaust device 22 may include an exhaust duct and a second fan provided in the exhaust duct. The exhaust duct communicates the indoor space with the outdoor environment. When the second fan is turned on, it can drive indoor air out of the room.

[0071] In other embodiments, the fresh air machine 2 may also be a one-way flow fresh air machine, and the fresh air machine 2 is provided with an air supply device 21 and no exhaust device.

[0072] Furthermore, in this embodiment, the fresh air machine 2 further includes a heat pump system 23. The heat pump system 23 includes a first heat exchanger, a throttling component, and a second heat exchanger. The first heat exchanger and the second heat exchanger are respectively connected to the exhaust port and the suction port of the compressor. The first heat exchanger, the throttling component, and the second heat exchanger are connected in sequence. Further, the heat pump system 23 may further include a commutation component, and the exhaust port, the suction port of the compressor, the first heat exchanger, and the second heat exchanger are all connected to the commutation component.

[0073] In this embodiment, the first heat exchanger is arranged in the fresh air duct, and the second heat exchanger is arranged in the exhaust air duct or the outdoor environment. When the second heat exchanger is arranged in the exhaust air duct, the energy of the exhausted indoor air can be recovered.

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

[0076] Furthermore, the number of heat pump systems 23 in the fresh air unit 2 can be more than one. At least two heat exchangers corresponding to different heat pump systems 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.

[0077] The exhaust system 3 can include one or more exhaust fans. When more than one exhaust fan adjusts the indoor space, different exhaust fans adjust different indoor areas. The exhaust fan can include an exhaust fan, an oil fume exhaust fan, etc.

[0078] 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 with each other 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.

[0079] Those skilled in the art can understand that Figure 1 the device structure shown in

[0080] does not constitute a limitation on the device, and may include more or fewer components than shown in the figure, or combine some components, or have different component arrangements. Figure 1 As shown in

[0081] In Figure 1In 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.

[0082] An embodiment of the present invention also provides a control method for an environmental control device, which is applied to the above environmental control device.

[0083] Referring to Figure 2 , an embodiment of the control method of the environmental control device of the present application is proposed. In this embodiment, the control method of the environmental control device includes:

[0084] Step S10, controlling the fresh air fan and the exhaust system to operate;

[0085] Here, the operation of the fresh air fan and the exhaust system means that both the fresh air fan and the exhaust system are in the on state. The operating parameters during the operation of the fresh air fan and / or the exhaust system can be pre-set fixed parameters, or parameters determined according to the actual operating conditions of the environmental control device or the user-set parameters. In this embodiment, the air state parameters for the environmental control device to adjust the indoor space are obtained, and the fresh air fan 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 fan can be determined according to the air state parameters, the fresh air fan 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. Another example is that 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 fan operates at a high fresh air volume, otherwise the fresh air fan operates at a low fresh air volume; or, when the pollutant concentration is greater than the second preset concentration, the fresh air fan operates at a high fresh air volume, otherwise the fresh air fan operates at a low fresh air volume.

[0086] Step S20, obtaining a first air volume parameter of the fresh air fan and a second air volume parameter of the exhaust system;

[0087] Both the first air volume parameter and the second air volume parameter are parameters detected at the current moment.

[0088] When the fresh air fan is a unidirectional flow fresh air fan, the first air volume parameter includes the first air supply volume of the fresh air fan, where the first air supply volume can be understood as the rated air supply volume of the fresh air fan, and the first air supply volume can also be understood as the air supply volume of the fresh air fan in the current operating state.

[0089] When the fresh air unit is a two-way flow fresh air unit and the fresh air unit includes a air supply device and an exhaust device, the first air volume parameter includes the second air supply volume of the air supply device, where the second air supply volume can be understood as the rated air supply volume of the air supply device, and the second air supply volume can also be understood as the air supply volume of the air supply device in the current operating state.

[0090] The second air volume parameter includes the third exhaust air volume of the exhaust system. The second air volume parameter can be understood as the total exhaust air volume of the exhaust system in the current operating state.

[0091] Step S30, determine whether the indoor space meets the preset positive pressure condition according to the first air volume parameter and the second air volume parameter;

[0092] The indoor space meets the preset positive pressure condition indicates that the indoor space is in a positive pressure state.

[0093] Specifically, a target relationship (such as a magnitude relationship or a quantitative relationship, etc.) between the first air volume parameter and the second air volume parameter when the indoor space meets the preset positive pressure condition and the indoor space is in a positive pressure state can be preset in advance. Among them, the magnitude relationship includes the magnitude relationship between the first air volume parameter multiplied by a preset coefficient and the second air volume parameter, and this preset coefficient is related to the type of fresh air unit. The preset coefficient of a two-way flow fresh air unit is less than that of a one-way flow fresh air unit. When the relationship between the first air volume parameter and the second air volume parameter matches the target relationship, it is determined that the indoor space meets the preset positive pressure condition; when the relationship between the first air volume parameter and the second air volume parameter does not match the target relationship, it is determined that the indoor space does not meet the preset positive pressure condition.

[0094] Step S40, when the indoor space does not meet the preset positive pressure condition, control at least one of the exhaust fans to shut down or control the exhaust system to reduce the exhaust air volume.

[0095] When controlling at least one exhaust fan to shut down, one exhaust fan can be randomly selected to shut down, or the exhaust fans that meet the conditions can be controlled to shut down. The number of exhaust fans that need to be shut down can be determined according to the deviation between the current air pressure in the indoor space and the target air pressure and the exhaust air volume of the currently operating exhaust fans, or it can also be determined according to the user's instruction.

[0096] Controlling the exhaust system to reduce the exhaust air volume can include controlling the fan in the exhaust system to reduce the speed or controlling the exhaust valve of the exhaust system to close or reduce the opening degree, etc. The exhaust air volume that the exhaust system needs to reduce can be determined according to the deviation between the current air pressure in the indoor space and the target air pressure and the exhaust air volume of the currently operating exhaust fans, or it can also be determined according to the user's instruction.

[0097] A control method for an environmental conditioning device proposed by an embodiment of the present invention. During the operation of both the fresh air unit and the exhaust system, when it is determined that the indoor space cannot reach a positive pressure state based on the first air volume parameter of the fresh air unit and the second air volume parameter of the exhaust system, at least one exhaust fan in the exhaust system is controlled to close or the exhaust volume of the exhaust system is controlled to decrease, thereby effectively preventing the exhaust system from being too large, ensuring that the indoor space can reach a positive pressure state, reducing the entry of outdoor air into the indoor environment, effectively improving the indoor air quality, enhancing indoor comfort, and avoiding condensation in the indoor space.

[0098] Further, in this embodiment, the step of determining whether the indoor space meets the preset positive pressure condition according to the first air volume parameter and the second air volume parameter includes: determining the maximum exhaust volume of the exhaust system according to the first air volume parameter; when the second air volume parameter is greater than or equal to the maximum exhaust volume, it is determined that the indoor space does not meet the preset positive pressure condition.

[0099] In an implementation manner of this embodiment, when the fresh air unit is a unidirectional flow fresh air unit, the first air volume parameter includes the first air supply volume of the fresh air unit, then the first air supply volume is reduced to obtain the maximum air volume of the exhaust system.

[0100] Wherein, when the exhaust system includes more than one exhaust fan, the maximum air volume here is the maximum exhaust volume of all exhaust fans (the sum of the air volumes of all exhaust fans).

[0101] The reduction of the first air supply volume can be adjusted according to a preset fixed adjustment value, or can be adjusted according to the air volume adjustment value determined by the parameters determined according to the actual operating conditions of the equipment.

[0102] For example, the maximum air volume Qmax = Q_SA * a, where Q_SA is the first air supply volume (the first air volume parameter), a is the air volume adjustment value, the air volume adjustment value is less than 1, and the value range of the air volume adjustment value is [0.8, 0.9].

[0103] In an implementation manner of this embodiment, when the fresh air unit is a bidirectional flow fresh air unit, the first air volume parameter includes the second air supply volume of the air supply device, then the second air supply volume is reduced to obtain the maximum air volume of the exhaust system.

[0104] Wherein, when the exhaust system includes more than one exhaust fan, the maximum air volume here is the maximum exhaust volume of all exhaust fans.

[0105] The reduction of the second air supply volume can be adjusted according to a preset fixed adjustment value, or can be adjusted according to the air volume adjustment value determined by the parameters determined according to the actual operating conditions of the equipment.

[0106] For example, the maximum air volume Qmax = Q_SA * b, where Q_SA is the first air supply volume (the first air volume parameter), b is the air volume adjustment value, the air volume adjustment value is less than 1, and the value range of the air volume adjustment value is [0.3, 0.5].

[0107] In another implementation manner of this embodiment, when the fresh air machine is a two-way flow fresh air machine, the air volume state parameter includes the second air supply volume and the first exhaust air volume of the fresh air machine, and then the maximum air volume of the exhaust system is determined according to the second air supply volume and the first exhaust air volume.

[0108] Wherein, when there are more than one exhaust fan in the exhaust system, the maximum air volume here is the maximum exhaust air volume of all exhaust fans.

[0109] In one implementation manner, reduce the second air supply volume to obtain the reference total exhaust air volume of the indoor space; determine the maximum air volume according to the difference between the reference total exhaust air volume and the first exhaust air volume. Reducing the second air supply volume can be adjusted according to a preset fixed adjustment value, or can be adjusted according to the air volume adjustment value determined by the parameters of the actual operating conditions of the equipment. The reference total exhaust air volume here is specifically the total exhaust air volume of the indoor space when the indoor and outdoor reach the air pressure balance state during the air supply process of the fresh air machine. The calculated difference here is the maximum air volume. For example, the maximum air volume Qmax = Q_SA * a - Q_EA, where Q_SA is the first air supply volume, Q_EA is the first exhaust air volume, a is the air volume adjustment value, the air volume adjustment value is less than 1, the value range of the air volume adjustment value is [0.8, 0.9], and Q_SA * a is the reference total exhaust air volume.

[0110] In another implementation manner, determine the difference between the second air supply volume and the first exhaust air volume to obtain the reference exhaust air volume of the exhaust system, and reduce the reference exhaust air volume to obtain the maximum air volume. The reference exhaust air volume here is specifically the exhaust air volume of the exhaust system when the indoor and outdoor reach the air pressure balance state during the air change process of the fresh air machine.

[0111] In this embodiment, through the above method, it can be ensured that during the air supply process of the fresh air machine, it can accurately identify whether the indoor space is in a positive pressure state.

[0112] Further, based on the above embodiment, another embodiment of the control method of the environmental adjustment device of the present application is proposed. 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:

[0113] Control at least one of the at least two target exhaust fans to shut down until the indoor space meets the preset positive pressure condition.

[0114] Control one of the target exhaust fans to shut down. After shutdown, determine whether the indoor space meets the preset positive pressure condition. If not, continue to control the next target exhaust fan to shut down. If so, stop shutting down the exhaust fans.

[0115] 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.

[0116] In this embodiment, at least one of the at least two target exhaust fans is shut down until the indoor space meets the preset positive pressure condition, thereby avoiding unnecessary shutdown of the exhaust fans and ensuring that the indoor space can reach positive pressure while meeting the indoor exhaust requirements.

[0117] Further, in this embodiment, the step of controlling at least one of the exhaust fans to shut down includes: controlling at least one of the exhaust fans that meets the preset conditions to shut down, and the preset conditions include being in the automatic control mode and / or the smoke machine in the corresponding area being in the on state.

[0118] The control mode of the exhaust fan can include one of the automatic control mode and the manual control mode. The manual control mode is a mode of controlling in response to a user instruction, and the automatic control mode is a mode of controlling according to a pre-stored control logic.

[0119] Different exhaust fans can correspond to different control modes. Some exhaust fans can be in the manual control mode, and some exhaust fans can be in the automatic control mode. The exhaust fans in the manual control mode are not used as target exhaust fans and will not be automatically shut down when the indoor space does not meet the preset positive pressure condition.

[0120] In this embodiment, during the process of controlling the operation of the environmental adjustment equipment, the priority of forcibly turning on the exhaust fan in the corresponding area when the smoke machine is shut down is higher than the priority of forcibly shutting down the exhaust fan when the indoor space does not meet the preset positive pressure condition. Therefore, the exhaust fans when the smoke machine in the corresponding area is in the on state are used as target exhaust fans.

[0121] In this embodiment, only the exhaust fans in the automatic control mode and when the smoke machine in the corresponding area is not shut down will be used as the exhaust fans to be shut down, which is beneficial to ensuring that the operation of the exhaust fan can accurately meet the user's exhaust requirements and ensuring the air quality in the adjustment area of the exhaust fan.

[0122] Further, in an implementation manner of this embodiment, the step of controlling at least one of the at least two target exhaust fans to shut down until the indoor space meets the preset positive pressure condition includes:

[0123] Control at least one of the target exhaust fans to shut down every preset duration until the indoor space meets the preset positive pressure condition.

[0124] Specifically, control one of the target exhaust fans to shut down, with an interval of a preset duration, and determine whether the current total exhaust air volume of the environmental control device is greater than or equal to the maximum exhaust air volume. If so, return to execute the step of "control one of the target exhaust fans to shut down, with an interval of a preset duration, and determine whether the current total exhaust air volume of the environmental control device is greater than or equal to the maximum exhaust air volume"; if not, stop shutting down the target exhaust fan.

[0125] The preset duration here can be a fixed duration set in advance, such as 5 minutes, etc. Alternatively, the preset duration can also be a duration determined according to the actual operating state of the environmental control device. For example, the preset duration can be determined according to the air volume deviation value between the current total exhaust air volume and the maximum exhaust air volume of the current environmental control device, and so on.

[0126] In this embodiment, through the above method, it can be ensured that the indoor space can reach positive pressure while meeting the indoor exhaust air demand.

[0127] Further, in another implementation manner of this embodiment, the step of controlling at least one of the at least two target exhaust fans to shut down 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 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.

[0128] 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.

[0129] The operating state parameters include at least one of the following: open / close state, service life duration, continuous operation duration, etc.

[0130] 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 can be 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 to calculate the shutdown priority. In still 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 can be determined according to the sum of all evaluation values.

[0131] 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.

[0132] In this embodiment, the operating state parameters include the opening and closing states of the corresponding controller. The opening and closing states include the open state or the closed state, and the shutdown priority corresponding to the open state is lower than the shutdown priority corresponding to the closed state. The controller here can be a wired controller connected to the exhaust fan in the indoor space.

[0133] For example, in the cooling mode, the comfortable temperature is 16 degrees. Defining that the lower the importance value, the higher the shutdown priority, the different regional temperatures and importance values are shown in the following table:

[0134] Zone temperature (°C) (16，18] (18，20] (20，22] (22，+∞) Importance value 8 6 4 2

[0135] Another example, in the heating mode, the comfortable temperature is 24 degrees. Defining that the lower the importance value, the higher the shutdown priority, the different regional temperatures and importance integrals are shown in the following table:

[0136] Zone temperature (°C) (24，26] (26，28] (28，30] (30，+∞) Importance value 2 4 6 8

[0137] Still another example, defining that the lower the importance value, the higher the shutdown priority, the importance value of the controller in the open state is 10 points, and the importance value of the controller in the closed state is 0 points.

[0138] In this embodiment, shutting down one by one with the highest priority, that is, the exhaust fan with the smallest exhaust demand in all spaces, is beneficial to meeting the exhaust demands of different regions to the greatest extent, ensuring the normal use of the exhaust fan, and at the same time ensuring that the indoor space can reach a positive pressure state.

[0139] Further, in this embodiment, the operating state parameters include the opening and closing states and the operating duration of the corresponding controller. Here, the operating duration is specifically the duration that the exhaust fan has been continuously operating in the current open state. The step of determining the target exhaust fan with the highest shutdown priority according to the air state parameters and / or the operating state parameters includes: determining the importance value of each open target exhaust fan according to the air state parameters and the opening and closing states; when there are more than one alternative exhaust fans, determining the exhaust fan with the longest corresponding operating duration among the more than one alternative exhaust fans as the target exhaust fan with the highest shutdown priority; wherein, the alternative exhaust fan is the target exhaust fan with the lowest corresponding importance value.

[0140] In this embodiment, the air state parameters include pollutant concentration and / or regional temperature and / or regional humidity; the importance value is positively correlated with the pollutant concentration, the temperature difference value between the regional temperature and the corresponding comfortable temperature is positively correlated with the importance value, and the humidity difference value between the regional humidity and the corresponding set humidity is positively correlated with the importance value.

[0141] In this embodiment, the opening and closing state includes an open state or a closed state, and the importance value corresponding to the open state is higher than the importance value corresponding to the closed state.

[0142] Specifically, the importance value of the corresponding target exhaust fan can be determined according to the sum of the importance value corresponding to the air state parameter and the importance value corresponding to the opening and closing state.

[0143] When the number of alternative exhaust fans is one, the target exhaust fan with the lowest importance value is used as the target exhaust fan with the highest shutdown priority.

[0144] When the number of alternative exhaust fans is more than one, compare the operating durations corresponding to each alternative exhaust fan, and use the alternative exhaust fan with the longest operating duration as the target exhaust fan with the highest shutdown priority.

[0145] In this embodiment, through the above method, it is beneficial to ensure the air quality of each indoor area adjusted by the exhaust system while improving the service life of the exhaust system.

[0146] In other embodiments, when the number of alternative exhaust fans is more than one, more than one alternative exhaust fan can be controlled to be closed.

[0147] Further, in this embodiment, after the step of controlling at least one of the exhaust fans to shut down, the following is further included:

[0148] When the indoor space meets the preset positive pressure condition and meets the first condition, the exhaust fan controlled to shut down is maintained in the closed state;

[0149] Among them, the first condition includes at least one of the following:

[0150] Condition 1, the smoke machine in the area adjusted by the exhaust fan controlled to shut down is in the open state;

[0151] Condition 2, the air quality parameters in the area adjusted by the exhaust fan controlled to shut down are within the target parameter range;

[0152] Condition 3, the continuous operating duration of the exhaust fan controlled to shut down before shutdown is greater than the set duration.

[0153] Here, the exhaust fan controlled to shut down refers to the exhaust fan that is closed when the indoor space does not meet the preset positive pressure condition.

[0154] When the indoor space is in a positive pressure state and meets Condition 1, it indicates that the exhaust air demand in the area that was previously forced to be closed can be met by the range hood. At this time, keeping the exhaust fan closed is beneficial to saving energy consumption.

[0155] When the indoor space is in a positive pressure state and meets Condition 2, it indicates that the air quality in the area that was previously forced to be closed is relatively good and there is no exhaust air demand. At this time, keeping the exhaust fan closed is beneficial to saving energy consumption.

[0156] When the indoor space is in a positive pressure state and meets Condition 3, it indicates that the previously forced - closed fan has been running for a long time. At this time, keeping the exhaust fan closed is beneficial to extending the service life of the exhaust fan.

[0157] Furthermore, when the indoor space meets the preset positive pressure condition and does not meet the first condition, the controlled - off exhaust fan is turned on to improve the indoor air quality.

[0158] Furthermore, based on any of the above - mentioned embodiments, another embodiment of the control method of the environmental conditioning equipment of the present application is proposed. In this embodiment, when the fresh air unit is a two - way fresh air unit, the fresh air unit includes a air supply device and an exhaust device. Referring to Figure 3 , the control method of the environmental conditioning equipment further includes:

[0159] Step S100, control both the air supply device and the exhaust device to be turned on, and obtain the third exhaust air volume of the exhaust system in the indoor space adjusted by the fresh air unit, the fourth exhaust air volume of the exhaust device, and the fresh air volume of the air supply device;

[0160] The operating parameters when both the air supply device and the exhaust device are turned on can be pre - set fixed parameters, or can be parameters determined according to the actual operating conditions of the fresh air unit or user - set parameters. For example, the operating parameters when the air supply device and the exhaust device are turned on can be determined according to indoor air state parameters and / or outdoor air state parameters.

[0161] Specifically, the initial air supply volume of the air supply device can be determined according to the actual working condition parameters, the initial exhaust air volume of the exhaust device can be determined according to the initial air supply volume, the air supply device is controlled to be turned on according to the initial air supply volume, and the exhaust device is controlled to be turned on according to the initial exhaust air volume.

[0162] When the continuous duration of both the air supply device and the exhaust device being turned on is greater than or equal to the preset duration, obtain the third exhaust air volume, the fourth exhaust air volume, and the fresh air volume here.

[0163] The third exhaust air volume can be determined based on the operating parameters of the exhaust system obtained through the communication connection between the fresh air unit and the exhaust system.

[0164] The air volume of the fourth row can be determined according to the operating speed of the second fan in the exhaust device or obtained from the rated parameters of the exhaust device.

[0165] The fresh air volume can be determined according to the operating speed of the first fan in the air supply device.

[0166] Step S200: Determine the fresh air control parameters of the air supply device and the exhaust control parameters of the exhaust device according to the third row air volume, the fourth row air volume, and the fresh air volume.

[0167] The fresh air control parameters may include at least one of the following: target fresh air volume, fresh air adjustment volume, maximum fresh air volume, and minimum fresh air volume. In this embodiment, the fresh air control parameter includes the minimum fresh air volume.

[0168] The exhaust control parameters may include at least one of the following: target exhaust air volume, exhaust air adjustment volume, maximum exhaust air volume, and minimum exhaust air volume. In this embodiment, the exhaust control parameter includes the maximum exhaust air volume.

[0169] In one implementation, the fresh air control parameters can be determined by combining the third row air volume, the fourth row air volume, and the fresh air volume, and the exhaust control parameters can be determined according to the fresh air control parameters and the third row air volume. In another implementation, the exhaust control parameters can also be determined according to the third row air volume, the fourth row air volume, and the fresh air volume, and the fresh air control parameters can be determined according to the exhaust control parameters and the third row air volume.

[0170] Step S300: Control the operation of the air supply device according to the fresh air control parameters and control the operation of the exhaust device according to the exhaust control parameters.

[0171] In this embodiment, the fresh air control parameter includes the minimum fresh air volume, and the air supply device is controlled to operate at a wind volume greater than or equal to the minimum fresh air volume. Specifically, obtain the current target fresh air volume of the air supply device; when the target fresh air volume is greater than the minimum fresh air volume, control the air supply device to operate at the target fresh air volume; when the target fresh air volume is less than or equal to the minimum fresh air volume, control the air supply device to operate at the minimum fresh air volume. Among them, the target fresh air volume here can be determined according to the actual needs 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 (such as at least one of the exhaust parameters and suction parameters of the compressor, the refrigerant inlet and outlet temperatures of the heat exchanger in the fresh air duct, etc., which represent reliability risks and / or heat exchange efficiency parameters).

[0172] In this embodiment, the exhaust air control parameter includes the maximum exhaust air volume, and the exhaust air device is controlled to operate at an air volume less than or equal to the maximum exhaust air volume. Specifically, the current target exhaust air volume of the exhaust air device is obtained; when the target exhaust air volume is greater than or equal to the maximum exhaust air volume, the exhaust air device is controlled to operate at the maximum exhaust air volume; when the target exhaust air volume is less than the maximum exhaust air volume, the exhaust air device is controlled to operate at the target exhaust air volume. Wherein, the target exhaust 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 (such as at least one of the exhaust parameters, return air parameters of the compressor, and the refrigerant inlet and outlet temperatures of the heat exchanger in the fresh air duct, etc., which represent reliability risks and / or heat exchange efficiency parameters).

[0173] In other implementation manners, when the fresh air control parameter includes the target fresh air volume, the air supply device is controlled to operate at the target fresh air volume. When the fresh air control parameter includes the fresh air adjustment amount, the air supply device is controlled to adjust the air supply volume according to the fresh air adjustment amount. When the fresh air control parameter includes the minimum fresh air volume, when the target fresh air volume is less than or equal to the minimum fresh air volume, the air supply device is controlled to operate at the minimum fresh air volume; when the target fresh air volume is greater than the minimum fresh air volume, the air supply device is controlled to operate at the target fresh air volume. When the exhaust air control parameter includes the target exhaust air volume, the exhaust air device is controlled to operate at the target exhaust air volume. When the exhaust air control parameter includes the exhaust air adjustment amount, the exhaust air device is controlled to adjust the exhaust air volume according to the exhaust air adjustment amount. When the exhaust air control parameter includes the minimum exhaust air volume, the exhaust air device is controlled to operate at the minimum exhaust air volume.

[0174] A control method for an environmental regulation device proposed in an embodiment of the present invention combines the exhaust air volume of the exhaust air system in the indoor space adjusted by the fresh air machine, the exhaust air volume of the exhaust air device in the fresh air machine, and the air supply volume of the air supply device in the fresh air machine to control the air supply and exhaust of the fresh air machine during the process of the fresh air machine simultaneously supplying and exhausting air, thereby effectively avoiding insufficient fresh air volume when the fresh air machine and the exhaust air system are simultaneously turned on, so that the indoor space adjusted by the fresh air machine can reach a positive pressure state, reducing the entry of outdoor air into the room and affecting the indoor environment, improving the indoor comfort during the operation of the fresh air machine, and avoiding condensation in the indoor space.

[0175] The specific order of execution between S100 to step S300 and the above steps S10 to step S30 is not specifically limited.

[0176] Further, in this embodiment, steps S10 and / or step S100 are executed during the operation of the fresh air unit in the cooling mode or the operation of the air conditioner in the space regulated by the fresh air unit, so as to ensure that the indoor environment can be maintained in a positive pressure state and prevent high-humidity outdoor air from entering the room and causing condensation in the indoor space.

[0177] 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, referring to Figure 4 , 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 third exhaust air volume, the fourth exhaust air volume and the fresh air volume includes:

[0178] Step S201, determining the fresh air control parameter according to the third exhaust air volume and the fourth exhaust air volume;

[0179] In this embodiment, the fourth exhaust air volume is the minimum exhaust air volume of the fresh air unit set in advance.

[0180] In one implementation, the sum of the third exhaust air volume and the fourth exhaust air volume 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.

[0181] In another implementation, the third exhaust air volume is increased according to the first adjustment value to obtain the first fresh air volume; the fourth exhaust air volume 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.

[0182] Step S202, determining the exhaust control parameter according to the third exhaust air volume and the fresh air volume.

[0183] In one implementation, the difference between the fresh air volume and the third exhaust air volume is determined as the reference exhaust air volume, and the reference exhaust air volume is reduced according to the third adjustment value to obtain the target exhaust air volume or the maximum exhaust air volume of the exhaust device.

[0184] In another implementation, the third exhaust air volume is increased according to the fourth adjustment value to obtain the third exhaust air volume, and the difference between the fresh air volume and the third exhaust air volume is used as the maximum exhaust air volume or the target exhaust air volume of the exhaust device.

[0185] In yet another implementation, the fresh air volume is reduced according to the fifth adjustment value to obtain the reference fresh air volume, and the difference between the reference fresh air volume and the third exhaust air volume is the maximum exhaust air volume or the target exhaust air volume.

[0186] In this embodiment, through the above method, it is beneficial to ensure the coordinated cooperation between the fresh air unit and the exhaust system to ensure the positive pressure state in the room.

[0187] Further, in this embodiment, the step of determining the exhaust control parameter according to the third exhaust air volume 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 third exhaust air volume, and the exhaust control parameter includes the maximum exhaust air volume.

[0188] 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 be reduced 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 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.

[0189] 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 third exhaust air volume can be determined as the maximum exhaust air volume of the exhaust device.

[0190] 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 third exhaust air volume.

[0191] For example, if the fresh air volume is 450 cubic meters and the third exhaust air volume is 100 cubic meters, then the maximum exhaust air volume is 450 * 0.8 - 100 = 260 cubic meters.

[0192] 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.

[0193] Further, based on any of the above embodiments, another embodiment of the control method of the environmental regulation device of the present application is proposed. In this embodiment, the fresh air control parameter includes the minimum fresh air volume, the fourth exhaust air volume is the minimum exhaust air volume of the preset fresh air machine, and the step of determining the fresh air control parameter according to the third exhaust air volume and the fourth exhaust air volume includes: determining the minimum fresh air volume of the air supply device according to the third exhaust air volume and the minimum exhaust air volume.

[0194] The indoor space is adjusted by at least two of the fresh air machines, and different fresh air machines adjust different areas in the indoor space. For example, if the indoor space is the whole house, different fresh air machines can correspondingly adjust different rooms in the whole house. The step of determining the minimum fresh air volume of the air supply device according to the third exhaust air volume and the minimum exhaust air volume includes:

[0195] Determine the reference exhaust air volume of each fresh air unit according to the third row of air volume and the rated air volume of each fresh air unit; determine the minimum fresh air volume of each air supply device according to the reference exhaust air volume corresponding to each fresh air unit and the minimum exhaust air volume.

[0196] The rated air volume is specifically the maximum air volume that the fresh air unit allows to output under rated conditions. The rated air volume can be obtained by acquiring the parameters pre-stored in the system.

[0197] Determine the weight value corresponding to each fresh air unit according to the rated air volume of each fresh air unit, and determine the reference exhaust air volume of each fresh air unit according to the third row of air volume and the corresponding weight value.

[0198] The reference exhaust air volume here is the exhaust air volume of the exhaust system that each fresh air unit 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 fresh air unit needs to provide.

[0199] 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 fresh air unit according to the relationship value and the third row of air volume. The relationship value can 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 third row of air volume as the reference exhaust air volume.

[0200] In this embodiment, the total exhaust air volume of each fresh air unit can be determined according to the sum value of the reference exhaust air volume and the minimum exhaust air volume. The total exhaust air volume here is specifically the total exhaust air volume that each fresh air unit 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 a preset fixed air volume adjustment value to obtain the minimum fresh air volume here. It can also 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 units 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 row of air volume and the maximum air volume of the exhaust machine, etc.

[0201] In this embodiment, through the above method, when adjusting the indoor space by more than one fresh air unit, the exhaust air volume that needs to be borne when the indoor space reaches positive pressure can be allocated according to the output capacity of each fresh air unit, so as to formulate the minimum fresh air volume of each fresh air unit, so as to ensure that the energy efficiency of each fresh air unit can be effectively improved, and ensure that each fresh air unit can operate coordinately to ensure that the indoor space can reach the required positive pressure state.

[0202] In other embodiments, the sum of the third air exhaust volume and the minimum air exhaust volume may 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.

[0203] Further, based on any of the above embodiments, the fresh air machine further includes a heat pump system. Before 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 third air exhaust volume, the fourth air exhaust volume, and the fresh air volume, the following steps are further included: during the opening process of the air supply device and the exhaust device, controlling the heat pump system to be turned on to adjust the fresh air flowing through the air supply device, and obtaining the fresh air inlet temperature, the fresh air outlet temperature of the air supply device, and the indoor inlet temperature of the exhaust device; determining the target corresponding relationship between the third air exhaust volume, the fourth air exhaust volume, the fresh air volume, the fresh air control parameter, and the exhaust control parameter according to the fresh air inlet temperature, the fresh air outlet temperature, and the indoor inlet temperature; 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 third air exhaust volume, the fourth air exhaust volume, and the fresh air volume includes: determining the fresh air control parameter and the exhaust control parameter corresponding to the third air exhaust volume, the fourth air exhaust volume, and the fresh air volume according to the target corresponding relationship.

[0204] Specifically, a first temperature difference value between the fresh air inlet temperature and the fresh air outlet temperature may be determined, a second temperature difference value between the fresh air inlet temperature and the indoor inlet temperature may be determined, and the target corresponding relationship here is obtained according to the first temperature difference value and the second temperature difference value.

[0205] In this embodiment, through the above method, it is beneficial to reduce the influence of the indoor temperature fluctuation during the air change process of the fresh air machine on the air pressure, and further ensure that the indoor space can accurately reach the target positive pressure state.

[0206] In addition, an embodiment of the present invention further provides a storage medium, on which a control program of an environmental adjustment device is stored.
