The air treatment system controls the temperature of the air output by the dehumidification module according to the indoor temperature to ensure that the temperature of the air output by the dehumidification module is higher than or equal to the indoor temperature, thereby effectively preventing the air pipeline and the indoor from generating dew, avoiding the indoor and the air pipeline from generating mould due to the dew, improving the comfort level of users and ensuring the health of the users.
In addition, the temperature of the air output by the dehumidification module is controlled according to the indoor temperature, so that the accuracy of a control result can be ensured, the dehumidification operation is more beneficial, and the scheme can be flexibly realized with low cost due to the fact that the information of the indoor temperature is easy to obtain;

In some embodiments, the air treatment system 100 controls the temperature of the air output from the dehumidifying module 120 such that the temperature of the air output from the dehumidifying module 120 is higher than or equal to the indoor temperature, for example, when the indoor temperature and the temperature of the air output from the dehumidifying module 120 are lower than the indoor temperature, according to the comparison result of the indoor temperature and the temperature of the air output from the dehumidifying module 120, thereby preventing the occurrence of the condensation phenomenon.

For example, when the temperature of the air output from the dehumidification module 120 is lower than the indoor temperature, when the outdoor temperature is higher, the temperature of the air output from the dehumidification module 120 can be increased by increasing the air volume of the first fan 111 of the air supply module 110, that is, increasing the flow rate of the air entering the dehumidification module 120, thereby preventing the occurrence of the condensation phenomenon.
Next, a specific description will be given of a method for determining the "indoor temperature" in the embodiment of the present application.
In some embodiments, the indoor temperature is an indoor actual temperature or an indoor dew point temperature. In some embodiments, "indoor dew point temperature" refers to a temperature at which condensation occurs in the room, e.g., the indoor dew point temperature may be calculated from at least one of indoor air pressure, indoor actual temperature, indoor humidity, etc. For specific calculation methods, reference may be made to the related art, and details are not repeated here.
In some embodiments, "indoor actual temperature" refers to the actual temperature of the air within the indoor space;
In some embodiments, the "indoor space" does not include a space above the ceiling, and the air supply module 110 and the dehumidification module 120 are disposed within the space above the ceiling.
For example, if a sensor is specially provided near the duct above the ceiling to detect the temperature of the duct, the control accuracy is lowered due to a possible difference between the temperature and the actual indoor temperature, affecting the suppression effect on indoor condensation, and on the other hand, since a special sensor for detecting the temperature of the duct is required to be installed above the ceiling, installation and equipment costs are increased, and maintenance and replacement are inconvenient.
In the embodiment of the application, the control is performed based on the 'indoor actual temperature', and the information of the indoor actual temperature is easy to obtain, so that the scheme of the application can be flexibly and low-cost realized, for example, various sensors existing in the indoor space can be selected according to the actual conditions, and the indoor actual temperature can be determined based on the detection values of the selected sensors.
In addition, control accuracy can be guaranteed based on control of the indoor actual temperature, so that the inhibition effect on dew condensation is guaranteed, and user comfort level is improved.
In some embodiments, the indoor actual temperature is determined according to a measured value of a temperature sensor provided in the indoor space.
For example, the temperature sensor provided in the indoor space means a temperature sensor provided under the indoor ceiling, whereby the indoor actual temperature can be accurately measured.
In some embodiments, the indoor actual temperature is determined according to a measured value of the sensor 301 provided in the suction port of the indoor unit 140 or the blow-out port of the indoor unit 140 or the controller 180 corresponding to the indoor unit 140;
Or the actual indoor temperature is determined according to the measured value of the external sensor 302;
Or the indoor actual temperature is determined based on the measured value of the sensor 303 provided on the controller 181 controlling the air supply module or the sensor 304 provided at the indoor air return opening of the air supply module 110.
For example, the controller 180 corresponding to the indoor unit 140 is at least one of a centralized controller, a line controller, and a remote controller.
For example, the sensor 301 provided in the suction port of the indoor unit 140 or the blowout port of the indoor unit 140 or the controller 180 corresponding to the indoor unit 140, the sensor 303 provided in the controller 181 controlling the blower module 110, and the sensor 304 provided at the indoor air return port of the blower module 110 are built-in sensors, and for example, the sensor 301 in the controller 180 corresponding to the indoor unit 140 is built-in to the controller 180.
For example, the controller 180 corresponding to the indoor unit 140 is electrically connected to the indoor unit through a wire line 190, and the controller 181 controlling the air blowing module is electrically connected to the air blowing module 110 through a wire line 191.
For example, the controller 181 corresponding to the air supply module 110 is at least one of a centralized controller, a line controller, and a remote controller.
In some embodiments, the indoor actual temperature is a maximum value of indoor actual temperatures of the plurality of indoor spaces. In this way, the temperature of the dehumidified air entering each indoor space can be ensured to be higher than or equal to the actual temperature of all indoor spaces, and the occurrence of dew condensation in all the indoor spaces can be prevented.
For example, with respect to the sensors 301 provided in the suction port of the indoor unit 140 or the blowout port of the indoor unit 140 or the controller 180 corresponding to the indoor unit, the "indoor actual temperature" is determined by the maximum value among the measured values of the respective sensors 301;
For example, with respect to the external sensors 302 provided in the respective indoor spaces, the "indoor actual temperature" is determined from the maximum value among the measured values of the external sensors 302 in the plurality of indoor spaces;
For example, in the air processing system having the built-in sensor and the external sensor, for example, the "indoor actual temperature" is determined based on the maximum value among the measured values of all the sensors 301, the external sensor 302, the sensor 303 on the controller 181 that controls the blower module, and the sensor 304 at the indoor air return port of the blower module 110, which are provided in the suction port of the indoor unit 140 or the blowout port of the indoor unit 140 or the controller 180 corresponding to the indoor unit 140.
In some embodiments, the actual temperature within the chamber is determined based on measurements from selected sensors. That is, the various sensors in the indoor space can be selected according to the actual situation, and the indoor actual temperature can be determined based on the detection value of the selected sensor, so that the scheme of the application can be flexibly implemented with low cost.
For example, one or more of the sensor 301 provided in the suction port of the indoor unit 140 or the blowout port 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 controlling the air blowing module, or the sensor 304 at the indoor air return port of the air blowing module 110 may be selected.
For example, the "actual indoor temperature" is determined from the maximum value of the measurements of the selected one or more sensors.
Therefore, through the measured value and the determining method of each sensor, the indoor actual temperature can be accurately obtained, so that the temperature of the air output by the dehumidification module can be accurately controlled, dew condensation in an air pipeline can be prevented, the comfort level of a user is improved, and the dehumidification operation is ensured.
Next, a specific description will be given of a method for determining the "temperature of air output from the dehumidification module" according to an embodiment of the present application.
In some embodiments, the temperature of the air output by the dehumidification module is determined based on the measurement of the temperature sensor 305 disposed at the dehumidification module outlet.
For example, the temperature sensor 305 provided at the dehumidification module air outlet is a built-in sensor.
Therefore, the temperature of the air output by the dehumidification module can be accurately obtained, the indoor actual temperature can be accurately obtained, and the temperature of the air output by the dehumidification module can be accurately controlled, so that dew condensation in an air pipeline can be prevented, the comfort level of a user is improved, and the dehumidification operation is guaranteed.
In some embodiments, the air treatment system 100 further includes a control module for performing related controls, such as controlling the temperature of the air output by the dehumidification module 120.
For example, the control module is provided in the dehumidification module 120.
For example, the control module generates a control command for controlling the temperature of the air output from the dehumidification module 120, and the dehumidification module 120 controls the flow rate of the refrigerant flowing through at least one of the second heat exchanger 122 and the first heat exchanger 121 based on the control command to control the temperature of the air output from the dehumidification module 120.
For example, the control module generates a control instruction for controlling the temperature of the air output from the dehumidification module 120, and inputs the control instruction to the air supply module 110, and 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 from the dehumidification module 120.
For example, the control module is the control substrate 123 of the dehumidification module 120.
According to the embodiment, 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, dew condensation in an air pipeline and the indoor space can be effectively prevented, mold caused by dew condensation in the indoor space and the air pipeline is avoided, the comfort level of a user is improved, and the health of the user is ensured. In addition, the outdoor fresh air can be introduced through the air supply module during the dehumidification operation, and the temperature of the air is controlled before the dehumidified fresh air is input into a room, namely, the fresh air is preprocessed, so that the load is not increased to the room when the fresh air is introduced, and the comfort of the indoor environment is ensured.
