In order to accurately control the wet air valve, the ventilation valve and the fresh air valve, in a preferred embodiment of the present application, the target wet air valve is determined based on a preset binding relationship between the wet air valve and the indoor unit, the target fresh air valve is determined based on a preset binding relationship between the fresh air valve and the indoor unit, and the target ventilation valve is determined based on a preset binding relationship between the ventilation valve and the indoor unit.
Specifically, after the address of the target indoor unit is determined, the target humidity valve, the target ventilation valve or the target fresh air valve can be determined according to the corresponding preset binding relationship. In a specific application scenario of the present application, as shown in fig. 3, the address dials of the valves 1 to 4, 1 ' to 4 ' and 1 "to 4" are the address dials of the indoor units connected to the air ducts thereof, respectively, and the binding relationships between the indoor units and the valve N, the valve N ' and the valve N "need to be manually set by an installation service engineer. For example, referring to the pipe connections in fig. 1, it can be seen that the pipe 1 corresponds to the valve 1, the valve 1 ', and the valve 1 ″ of the central humidifier, the central total heat exchanger, and the central fresh air machine, respectively, and corresponds to the address 1 indoor unit, and therefore, when dial-up binding is performed, the address dials of the valve 1, the valve 1', and the valve 1 ″ are all set to 1. According to the method, the binding relations of the pipelines 2-4 are set respectively.
For reliable control of the central total heat exchanger, in some embodiments of the present application, the converter is further configured to:
when a first ventilation opening instruction carrying the target indoor unit address is detected and the target wet air valve and the target fresh air valve are both in a closed state, opening the target ventilation valve according to the target indoor unit address;
and when a first ventilation closing instruction carrying the target indoor unit address is detected, closing the target ventilation valve according to the target indoor unit address.

and when a first fresh air closing instruction carrying the target indoor unit address is detected, closing the target fresh air valve according to the target indoor unit address.
Specifically, a first fresh air opening instruction is sent by a user to a target indoor unit corresponding to a target indoor unit address, when the converter detects the first fresh air opening instruction through an indoor and outdoor unit bus and a target wet air valve and a target ventilation valve corresponding to the target indoor unit address are both in a closed state, it is indicated that a fresh air demand exists in the target indoor unit, humidification and fresh air demands do not exist, and the target fresh air valve is opened according to the target indoor unit address.
And the first fresh air closing instruction is sent to the target indoor unit by a user, when the first fresh air closing instruction is detected based on an indoor and outdoor unit bus, the target indoor unit needs to stop fresh air, and the target fresh air valve is closed according to the address of the target indoor unit.
In order to reliably control the target humidification valve when the target indoor unit has both the humidification demand and the fresh air demand, in a preferred embodiment of the present application, the converter is further configured to:
when a second humidification opening instruction and a second fresh air opening instruction which carry the address of the target indoor unit are detected and a first preset humidity valve opening condition is met, opening the target humidity valve according to the address of the target indoor unit;
when a second humidification closing instruction corresponding to the second humidification opening instruction is detected and a first preset air valve closing condition is met, closing the target air valve according to the target indoor unit address;

the first preset wet gas valve closing condition includes: and the target indoor unit receives the second humidification closing instruction, the indoor humidity is not less than the specified humidity, and the target humidity valve is kept in an opening state for a preset time.
Specifically, the second humidification starting instruction may be sent by the user to the target indoor unit, or triggered when the indoor humidity is less than a specified humidity. The second fresh air starting instruction can be sent to the target indoor unit by the user.
When a second humidification opening instruction and a second fresh air opening instruction are detected, the fact that humidification and fresh air requirements exist in a target indoor unit at the same time is indicated, and when a first preset humidity valve opening condition is met, a target humidity valve is opened according to the address of the target indoor unit. Since the target fresh air valve, the target wet air valve and the target ventilation valve are in the same pipeline, in order to avoid air flow conflict, on the premise that the target fresh air valve and the target ventilation valve are in a closed state, the target indoor unit receives the second humidification opening instruction and opens the target wet air valve when the indoor humidity is smaller than the specified humidity.
The second humidification closing instruction can be sent by a user to a target indoor unit or triggered when the indoor humidity is not less than the specified humidity, when the second humidification closing instruction corresponding to the second humidification opening instruction is detected, it is described that the target indoor unit needs to stop introducing moisture when the moisture and the fresh air are introduced at the same time, and the target moisture valve is closed when the first preset moisture valve closing condition is met.
