[0002] With the continuous advancement of science and technology and the improvement of living standards, people have higher and higher requirements for living environment, among which indoor temperature and humidity are important indicators of living environment. For example, in rainy season or summer, the indoor air is relatively humid, and dehumidification equipment is needed to dehumidify the indoor air.

[0003] In the air handling system, when the dehumidification operation is performed, the moisture in the air is removed after the air passes through the evaporator installed in the room, and dry air is blown out to achieve the dehumidification effect.

[0004] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present application and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present application. Summary of the invention

[0005] The inventors have discovered that in existing air treatment systems, the temperature of outdoor air may be lower than the indoor temperature. In addition, the temperature of the air drops after passing through the evaporator. Therefore, the temperature of the air output by the dehumidification equipment may be lower than the indoor temperature, resulting in the possibility of condensation in the air ducts and indoors. In addition, condensation may also cause mold in the indoor room and air ducts, resulting in a decrease in user comfort and affecting user health.

[0006] In order to solve at least one of the above problems, the embodiments of the present application provide an air treatment system and a control method of the air treatment system. The air treatment system controls the temperature of the air output by the dehumidification module according to the indoor temperature, so that the temperature of the air output by the dehumidification module is higher than or equal to the indoor temperature; thereby effectively preventing condensation in the air pipeline and indoors, avoiding mold caused by condensation indoors and in the air pipeline, improving the user's comfort, and ensuring the user's health.

[0007] According to a first aspect of an embodiment of the present application, an air treatment system is provided, the air treatment system comprising:

[0008] an air supply module, the air supply module having a first fan for introducing air;

[0009] a dehumidification module, which is arranged at the output side of the air supply module and is used to dehumidify the air output by the air supply module, wherein the dehumidification module has a first heat exchanger for dehumidification;

[0010] The air handling system controls the temperature of the air output by the dehumidification module according to the indoor temperature, so that the temperature of the air output by the dehumidification module is higher than or equal to the indoor temperature.

[0011] According to a second aspect of an embodiment of the present application, a control method for an air treatment system is provided, the air treatment system comprising:

[0012] an air supply module, the air supply module having a first fan for introducing air;

[0013] a dehumidification module, which is arranged at the output side of the air supply module and is used to dehumidify the air output by the air supply module, wherein the dehumidification module has a first heat exchanger for dehumidification;

[0014] The control method comprises:

[0015] The temperature of the air output by the dehumidification module is controlled so that the temperature of the air output by the dehumidification module is higher than or equal to the indoor temperature.

[0016] One of the beneficial effects of the embodiments of the present application is that the air treatment system controls the temperature of the air output by the dehumidification module according to the indoor temperature, so that the temperature of the air output by the dehumidification module is higher than or equal to the indoor temperature; thereby effectively preventing condensation in the air duct and indoors, avoiding mold caused by condensation indoors and in the air ducts, improving user comfort, and ensuring user health.

[0017] In addition, since the temperature of the air output by the dehumidification module is controlled according to the indoor temperature, the accuracy of the control result can be guaranteed, which is more beneficial to the dehumidification operation; and since the indoor temperature information is easy to obtain, the present solution can be implemented flexibly and at low cost;

[0018] In addition, during the dehumidification operation, fresh air from outside can be introduced through the air supply module, and the temperature of the air can be controlled before the dehumidified fresh air is input into the room, that is, the fresh air is pre-treated, so that the load on the room is not increased when the fresh air is introduced, thereby ensuring the comfort of the indoor environment.

[0028] The preferred embodiments of the present application will be described below with reference to the accompanying drawings.

[0029] Example 1

[0030] Embodiment 1 of the present application provides an air treatment system.

[0031] Figure 1 Schematic diagram of the air treatment system of Example 1 of the present application. Figure 1 In the figure, the solid arrow indicates the flow direction of the air inside the air supply module, and the hollow arrow indicates the flow direction of the air outside the air supply module.

[0032] Figure 2It is another schematic diagram of the air treatment system of Example 1 of the present application. Figure 2 and Figure 1 The same air handling system 100 is shown. Figure 2 In the figure, the solid arrow indicates the flow direction of the refrigerant, and the hollow arrow indicates the flow direction of the air outside the air supply module.

[0033] like Figure 1 and Figure 2 As shown, the air handling system 100 includes:

[0034] An air supply module 110 having a first fan 111 for introducing air;

[0035] The dehumidification module 120 is disposed at the output side of the air supply module 110 and is used to dehumidify the air output by the air supply module 110. The dehumidification module 120 has a first heat exchanger 121 for dehumidification.

[0036] In some embodiments, the air supply module 110 includes at least one of a fresh air processing device, a full heat exchange device (for example, with or without an internal circulation function), and a ventilation device (for example, with or without an internal circulation function).

[0037] In some embodiments, the air supply module 110 includes an outdoor air inlet (OA), an outdoor exhaust outlet (EA), an indoor air supply outlet (SA), and an indoor return air outlet (RA); wherein a first air circuit is formed between the outdoor air inlet (OA) and the indoor air supply outlet (SA), and a second air circuit is formed between the indoor return air outlet (RA) and the outdoor exhaust outlet (EA).

[0038] In some embodiments, the air supply module 110 further includes a second fan 112 for exhausting air to the outdoors and a total heat exchanger 113 , and the total heat exchanger 113 performs heat exchange between the air in the first air circuit and the air in the second air circuit.

[0039] For example, the first fan 111 is used to form an airflow so as to introduce air into the room through the indoor air supply port (SA).

[0040] For example, Figure 1 As shown, a first air circuit is formed between OA and SA; a second air circuit is formed between RA and EA; and the total heat exchanger 113 performs heat exchange between the air in the first air circuit and the second air circuit.

[0041] In some embodiments, the air supply module 110 has internal circulation and external circulation functions. For example, in the internal circulation mode, the air supply module 110 is used to introduce indoor air, and the air circulates between SA and RA; in the external circulation mode, the air supply module 110 is used to introduce outdoor air, and the air enters from OA and is discharged from SA, and then enters from RA and is discharged from EA;

[0042] In some embodiments, the air supply module 110 does not have an internal circulation function, for example Figure 1 As shown, air enters from OA and is discharged from SA, and then enters from RA and is discharged from EA.

[0043] In some embodiments, the air supply module 110 and the dehumidification module 120 are independently arranged and connected via an air duct 150; the control substrate 114 of the air supply module 110 and the control substrate 123 of the dehumidification module are independently arranged and electrically connected.

[0044] For example, Figure 1 As shown, the control substrate 114 of the air supply module 110 and the control substrate 123 of the dehumidification module are electrically connected through the air conditioning communication line 170.

[0045] For example, Figure 1 and Figure 2 As shown, the dehumidification module 120 is arranged at the output side of the air supply module 110, for example Figure 1 On the side where the SA is located, the dehumidification module 120 dehumidifies the air output by the air supply module 110 by passing through the first heat exchanger 121 with the refrigerant, and at this time, the first heat exchanger 121 operates as an evaporator.

[0046] In some embodiments, the dehumidification module 120 further includes: a second heat exchanger 122 or an electric heater, which is used to heat the air passing through the first heat exchanger 121 .

[0047] In some embodiments, the refrigerant input side of the second heat exchanger 122 is connected to the refrigerant input side of the first heat exchanger 121 , and the refrigerant output side of the second heat exchanger 122 is connected to the refrigerant output side of the first heat exchanger 121 .

[0048] like Figure 1 As shown, the air supply module 110 outputs air to the dehumidification module 120 through the air pipeline 150, the dehumidification module 120 dehumidifies the air output by the air supply module 110, and the second heat exchanger 122 heats the air passing through the first heat exchanger 121, and introduces the dehumidified air into multiple indoor spaces through the air pipeline 150; thereby, the user's comfort can be further improved.

[0049] For example, the electric heater is a PTC electric heater, which is an electric heater based on a semiconductor material and performs heating using the characteristics of a PTC (Positive Temperature Coefficient) material.

[0050] In some embodiments, the air treatment system 100 further includes an indoor unit 140 , which is electrically connected to the air supply module 110 .

[0051] For example, the indoor unit 140 is electrically connected to the air supply module 110 through the air conditioning communication line 170 .

[0052] In some embodiments, the indoor unit 140 further has a third heat exchanger 141 , a refrigerant input side of the third heat exchanger 141 is connected to a refrigerant input side of the first heat exchanger 121 , and a refrigerant output side of the third heat exchanger 141 is connected to a refrigerant output side of the first heat exchanger 121 .

[0053] In some embodiments, the number of the indoor unit 140 can be set to one or more. When the indoor unit 140 is set to multiple, the refrigerant input side of the third heat exchanger 141 of each indoor unit 140 is respectively connected to the refrigerant input side of the first heat exchanger 121 through the refrigerant gas pipeline 160, and the refrigerant output side of the third heat exchanger 141 of each indoor unit 140 is respectively connected to the refrigerant output side of the first heat exchanger 121 through the refrigerant liquid pipeline 161.

[0054] In some embodiments, the air treatment system 100 further includes an outdoor unit 130, which includes a compressor 131 and a fourth heat exchanger 132. In addition, the outdoor unit 130 may further include a pressure sensor 135, a bypass circuit 133, and a liquid storage tank 134.

[0055] In some embodiments, the outdoor unit 130, the indoor unit 140, the first heat exchanger 121, and the second heat exchanger 122 are connected via a refrigerant pipeline.

[0056] For example, Figure 1 and Figure 2 As shown, the refrigerant pipeline includes a refrigerant gas pipeline 160, which is input into the third heat exchanger 141 of the indoor unit 140 and the first heat exchanger 121; the refrigerant pipeline includes a refrigerant liquid pipeline 161, and the refrigerant pipeline also includes refrigerant high and low pressure pipelines 162, which are connected to the second heat exchanger 122.

[0057] In some embodiments, the refrigerant gas discharged from the compressor 131 of the outdoor unit 130 flows into the fourth heat exchanger 141 and the second heat exchanger 122, the refrigerant liquid condensed by the fourth heat exchanger 141 and the second heat exchanger 122 converges in the dehumidification module 120 and is supplied to the first heat exchanger 121, and the refrigerant gas evaporated by the first heat exchanger 121 flows to the input side of the compressor 131.

[0058] like Figure 2 As shown, the outdoor unit 130 further includes a bypass circuit 133 , a liquid reservoir 134 , and a valve 136 ; and the indoor unit 140 further includes a third fan 142 .

[0059] like Figure 2 As shown, starting from the output side of the compressor 131, the refrigerant gas is input to the fourth heat exchanger 132 and the second heat exchanger 122 through the refrigerant gas pipeline 160, and then the refrigerant liquid formed after cooling by the fourth heat exchanger 141 and the second heat exchanger 122 is converged in the dehumidification module 120 through the refrigerant liquid pipeline 161, for example, Figure 2 The refrigerant gas is converged at P1 and supplied to the first heat exchanger 121. Then, the refrigerant gas evaporated by the first heat exchanger 121 flows to the input side of the compressor through the refrigerant gas pipeline 160.

[0060] In some embodiments, the pressure sensor 135 of the outdoor unit 130 is used to detect the pressure on the input side of the compressor 131. For example, when the pressure detected by the pressure sensor 135 is higher than a preset pressure, the air volume of the first fan 11 of the air supply module 110 is stopped from increasing, or the refrigerant flow rate of the first heat exchanger 121 of the dehumidification module 120 is stopped from decreasing. In this way, the safety of the system operation can be ensured.

[0061] In some embodiments, the bypass circuit 133 of the outdoor unit 130 is used to control the refrigerant flow rate, for example, by increasing the refrigerant flow rate of the bypass circuit 133 of the outdoor unit 130 to reduce the refrigerant flow rate flowing into the first heat exchanger 121 of the dehumidification module 120. In this way, the refrigerant flow rate flowing into the first heat exchanger 121 can be effectively controlled through simple operations.

[0062] like Figure 2 As shown, the bypass circuit 133 bypasses from between the first heat exchanger 121 and the fourth heat exchanger 132 to the input side of the compressor 131, and the bypass circuit 133 has a valve 136 for adjusting the refrigerant flow rate. By adjusting the valve 136, the refrigerant flow rate in the bypass circuit 133 is increased, thereby reducing the refrigerant flow rate of the first heat exchanger 121 flowing into the dehumidification module 120. For example, the valve 136 is a solenoid valve SV or an electric valve EVT.

[0063] In some embodiments, Figure 1 As shown, the conditioning object of the air treatment system of the present application may include multiple indoor spaces, and the air output by the dehumidification module 120 after dehumidification can be respectively delivered to the multiple indoor spaces through air pipelines. In each indoor space, an indoor unit 140 is respectively arranged.

[0064] In addition, in some embodiments, the indoor unit 140 may be installed in part of the indoor space, while not installed in part of the indoor space.

[0065] In some embodiments, the air handling system 100 includes an air conditioning system. The air conditioning system may be a commercial air conditioning system or a residential air conditioning system.

[0066] In some embodiments, the air conditioning system may include at least one group of outdoor units and at least one indoor unit connected to each group of outdoor units. That is, the air conditioning system may include one or more groups of outdoor units, each group of outdoor units includes at least one outdoor unit; for a group of outdoor units, the group of outdoor units is connected to at least one indoor unit.

[0067] For example, an air conditioning system includes an outdoor unit and an indoor unit connected to the outdoor unit.

[0068] For example, the air conditioning system includes an outdoor unit and at least two indoor units connected to the outdoor unit.

[0069] For example, the air conditioning system includes at least two outdoor units and at least two indoor units connected to the at least two outdoor units.

[0070] For example, a group of outdoor units and at least one indoor unit connected to the group of outdoor units constitute a refrigerant system, or multiple groups of outdoor units and at least one indoor unit respectively connected to the multiple groups of outdoor units constitute multiple refrigerant systems. Thus, the air-conditioning system may include one refrigerant system or multiple refrigerant systems.

[0071] In some embodiments, the outdoor unit and the indoor unit may be air conditioning equipment of various models, types, forms, and capacities. For example, the indoor unit may be in the form of four-sided air outlet, two-sided air outlet, duct unit, ground air outlet, or skirting air outlet; the outdoor unit may be in the form of single fan upper air outlet, double fan upper air outlet, single fan front air outlet, or double fan front air outlet.

[0072] In some embodiments, the air treatment system of the present application further includes a network device, for example, the network device includes a cloud server 201, a router 202, a repeater 203 (such as an intelligent gateway) and a wireless access point 204 (access point, AP), etc.

[0073] For example, the wireless access point 204 can be set up in each room and connected to the router 202 via a wireless connection (for example, Wi-Fi, etc.); the repeater 203 is wirelessly connected to the router 202; and the repeater 203 is electrically connected to the outdoor unit 130 via the air conditioning communication line 170.

[0074] In some embodiments, Figure 1As shown, the air treatment system of the present application further includes an external sensor 302 disposed in the indoor space. For example, multiple indoor spaces are each provided with an external sensor 302 .

[0075] For example, the external sensor 302 is connected to the air supply module 110 via the relay 203 .

[0076] For example, a user can control an APP on a terminal device to control the operation mode of an air handling system through a network device.

[0077] In the embodiment of the present application, the air treatment system 100 controls the temperature of the air output by the dehumidification module 120 according to the indoor temperature, so that the temperature of the air output by the dehumidification module 120 is higher than or equal to the indoor temperature.

[0078] The air handling system controls the temperature of the air output by the dehumidification module according to the indoor temperature, so that the temperature of the air output by the dehumidification module is higher than or equal to the indoor temperature; thereby effectively preventing condensation in the air ducts and indoors, avoiding mold caused by condensation indoors and in the air ducts, improving user comfort and ensuring user health.

[0079] In addition, since the temperature of the air output by the dehumidification module is controlled according to the indoor temperature, the accuracy of the control result can be guaranteed, which is more beneficial to the dehumidification operation; and since the indoor temperature information is easy to obtain, the present solution can be implemented flexibly and at low cost;

[0080] In addition, during the dehumidification operation, fresh air from outside can be introduced through the air supply module, and the temperature of the air can be controlled before the dehumidified fresh air is input into the room, that is, the fresh air is pre-treated, so that the load on the room is not increased when the fresh air is introduced, thereby ensuring the comfort of the indoor environment.

[0081] In some embodiments, the air handling system 100 controls the temperature of the air output by the dehumidification module 120 based on the comparison result of the indoor temperature and the temperature of the air output by the dehumidification module 120. For example, when the indoor temperature and the temperature of the air output by the dehumidification module 120 are lower than the indoor temperature, the temperature of the air output by the dehumidification module 120 is controlled so that the temperature of the air output by the dehumidification module 120 is higher than or equal to the indoor temperature, thereby preventing the occurrence of condensation.

[0082] In some embodiments, the air handling system 100 controls the temperature of the air output by the dehumidification module 120 by controlling the refrigerant flow rate flowing through at least one of the second heat exchanger 122 and the first heat exchanger 121, so that the temperature of the air output by the dehumidification module 120 is higher than or equal to the indoor temperature.

[0083] For example, when the temperature of the air output by the dehumidification module 120 is lower than the indoor temperature, the refrigerant flow rate passing through the second heat exchanger 122 is increased to further increase the temperature of the air output by the dehumidification module 120, so that the temperature of the air output by the dehumidification module 120 is higher than or equal to the indoor temperature.

[0084] In some embodiments, alternatively, the air processing system 100 controls the temperature of the air output by the dehumidification module 120 by controlling the air volume of the first fan 111 of the air supply module 110 .

[0085] For example, when the temperature of the air output by the dehumidification module 120 is lower than the indoor temperature, and when the outdoor temperature is high, by increasing the air volume of the first fan 111 of the air supply module 110, that is, increasing the flow rate of air entering the dehumidification module 120, the temperature of the air output by the dehumidification module 120 can be increased to prevent the occurrence of condensation.

[0086] The following is a detailed description of the method for determining the "indoor temperature" in the embodiment of the present application.

[0087] In some embodiments, the indoor temperature is the actual indoor temperature or the indoor dew point temperature. In some embodiments, the "indoor dew point temperature" refers to the temperature of indoor condensation. For example, the indoor dew point temperature can be calculated based on at least one of the indoor air pressure, the actual indoor temperature, the indoor humidity, etc. The specific calculation method can refer to the relevant technology and will not be repeated here.

[0088] In some embodiments, "actual indoor temperature" refers to the actual temperature of the air in the indoor space;

[0089] In some embodiments, the “indoor space” does not include the space above the ceiling, and the air supply module 110 and the dehumidification module 120 are arranged in the space above the ceiling.

[0090] For example, if a sensor is specially installed near the air duct above the ceiling to detect the duct temperature, there may be a temperature difference between this temperature and the actual indoor temperature, which will lead to a decrease in control accuracy and affect the effect of suppressing indoor condensation. On the other hand, since a special sensor for detecting the air duct temperature needs to be installed above the ceiling, the installation and equipment costs are increased, and it is not convenient for maintenance and replacement.

[0091] In the embodiment of the present application, the control is performed based on the "actual indoor temperature". Since the information of the actual indoor temperature is easy to obtain, the solution of the present application can be implemented flexibly and at low cost. For example, according to the actual situation, various sensors already present in the indoor space can be selected, and the actual indoor temperature can be determined based on the detection value of the selected sensor.

[0092] In addition, control based on the "actual indoor temperature" can ensure control accuracy, thereby ensuring the suppression effect of condensation and improving user comfort.

[0093] In some embodiments, the actual indoor temperature is determined based on a measurement value of a temperature sensor disposed in the indoor space.

[0094] For example, the temperature sensor installed in the indoor space refers to a temperature sensor installed under the indoor ceiling, thereby being able to accurately measure the actual indoor temperature.

[0095] In some embodiments, the actual indoor temperature is determined based on a measurement value of a sensor 301 disposed in the suction port of the indoor unit 140 or the blowing port of the indoor unit 140 or in the controller 180 corresponding to the indoor unit 140;

[0096] Alternatively, the actual indoor temperature is determined based on the measurement value of the external sensor 302;

[0097] Alternatively, the actual indoor temperature is determined based on a measurement value of a sensor 303 disposed on the controller 181 for controlling the air supply module or a sensor 304 disposed at the indoor air return port of the air supply module 110 .

[0098] For example, the controller 180 corresponding to the indoor unit 140 is at least one of a centralized controller, a wired controller, and a remote controller.

[0099] For example, the sensor 301 provided at the air inlet of the indoor unit 140 or the air outlet of the indoor unit 140 or in the controller 180 corresponding to the indoor unit 140, the sensor 303 on the controller 181 controlling the air supply module 110, and the sensor 304 at the indoor air return outlet of the air supply module 110 are built-in sensors. For example, the sensor 301 in the controller 180 corresponding to the indoor unit 140 is built into the controller 180.

[0100] For example, the controller 180 corresponding to the indoor unit 140 is electrically connected to the indoor unit via a wired line 190 ; and the controller 181 controlling the air supply module is electrically connected to the air supply module 110 via a wired line 191 .

[0101] For example, the controller 181 corresponding to the air supply module 110 is at least one of a centralized controller, a wired controller, and a remote controller.

[0102] In some embodiments, the actual indoor temperature is the maximum value of the actual indoor temperatures of the multiple indoor spaces. In this way, it is possible to ensure that the temperature of the dehumidified air entering each indoor space is higher than or equal to the actual temperature of all indoor spaces, thereby preventing condensation from occurring in all indoor spaces.

[0103] For example, for a sensor 301 provided at the suction port of the indoor unit 140 or the blowing port of the indoor unit 140 or in the controller 180 corresponding to the indoor unit, the “actual indoor temperature” is determined by the maximum value of the measured values ​​of each sensor 301 ;

[0104] For example, for the external sensors 302 installed in each indoor space, the "actual indoor temperature" is determined based on the maximum value of the measured values ​​of the external sensors 302 in multiple indoor spaces;

[0105] For example, for an air treatment system having built-in sensors and external sensors, for example, the "actual indoor temperature" is determined based on the maximum value of the measured values ​​of all sensors including the sensor 301 set at the air inlet of the indoor unit 140 or the air outlet of the indoor unit 140 or the controller 180 corresponding to the indoor unit 140, the external sensor 302, the sensor 303 on the controller 181 that controls the air supply module, and the sensor 304 at the indoor air return outlet of the air supply module 110.

[0106] In some embodiments, the actual indoor temperature is determined based on the measured value of the selected sensor. That is, the above-mentioned various sensors in the indoor space can be selected according to the actual situation, and the actual indoor temperature can be determined based on the detection value of the selected sensor, so that the solution of the present application can be implemented flexibly and at low cost.

[0107] For example, one or more of the sensors selected may be a sensor 301 disposed at the air inlet of the indoor unit 140, the air outlet of the indoor unit 140, or the controller 180 corresponding to the indoor unit 140, or an external sensor 302, or a sensor 303 on the controller 181 that controls the air supply module, or a sensor 304 at the indoor air return outlet of the air supply module 110.

[0108] For example, the “actual indoor temperature” is determined according to the maximum value of the measurement values ​​of one or more selected sensors.

[0109] Therefore, through the measurement values ​​and determination methods of the above-mentioned sensors, the actual indoor temperature can be accurately obtained, so that the temperature of the air output by the dehumidification module can be accurately controlled, thereby preventing condensation in the air pipeline, improving user comfort, and ensuring the dehumidification operation.

[0110] Below, a method for determining the "temperature of the air output by the dehumidification module" according to an embodiment of the present application is described in detail.

[0111] In some embodiments, the temperature of the air output by the dehumidification module is determined based on the measurement value of the temperature sensor 305 disposed at the air outlet of the dehumidification module.

[0112] For example, the temperature sensor 305 provided at the air outlet of the dehumidification module is a built-in sensor.

[0113] In this way, the temperature of the air output by the dehumidification module can be accurately obtained, and the actual indoor temperature can be accurately obtained, so that the temperature of the air output by the dehumidification module can be accurately controlled, thereby preventing condensation in the air pipeline, improving user comfort, and ensuring the dehumidification operation.

[0114] In some embodiments, the air treatment system 100 further includes a control module, which is used to perform related controls, for example, to control the temperature of the air output by the dehumidification module 120 .

[0115] For example, the control module is provided in the dehumidification module 120 .

[0116] For example, the control module generates a control instruction for controlling the temperature of the air output by the dehumidification module 120. The dehumidification module 120 controls the refrigerant flow rate flowing through at least one of the second heat exchanger 122 and the first heat exchanger 121 according to the control instruction to control the temperature of the air output by the dehumidification module 120.

[0117] For example, the control module generates a control instruction for controlling the temperature of the air output by the dehumidification module 120, and inputs the control instruction to the air supply module 110. After receiving the instruction, the air supply module 110 controls the air volume of the first fan 111 of the air supply module 110 to control the temperature of the air output by the dehumidification module 120.

[0118] For example, the control module is the control substrate 123 of the dehumidification module 120 .

[0119] According to the above embodiment, the air handling system controls the temperature of the air output by the dehumidification module according to the indoor temperature, so that the temperature of the air output by the dehumidification module is higher than or equal to the indoor temperature; thereby, condensation can be effectively prevented in the air duct and indoors, and mold caused by condensation indoors and in the air duct can be avoided, thereby improving the comfort of the user and ensuring the health of the user. In addition, since the temperature of the air output by the dehumidification module is controlled according to the indoor temperature, the accuracy of the control result can be guaranteed, which is more beneficial to the dehumidification operation; and since the information of the indoor temperature is easy to obtain, the present solution can be implemented flexibly and at low cost; in addition, during the dehumidification operation, fresh air from the outdoors can be introduced through the air supply module, and the temperature of the air can be controlled before the dehumidified fresh air is input into the room, that is, the fresh air is pre-treated, so that the load on the room is not increased when the fresh air is introduced, thereby ensuring the comfort of the indoor environment.
