as shown in fig. 1, assuming that there are 8 indoor units (each of which is an address 0 to 7) in an air conditioning system, each central humidifier can provide 4 wet gas valves and wet gas pipelines, the air conditioner needs 2 central humidifiers (each of which is an address 0 to 1), and the 4 wet gas valves of the 2 central humidifiers can be separately controlled to meet the humidification requirements corresponding to the indoor units of addresses 0 to 7.
The controller comprises an indoor unit controller and a centralized controller which are connected with the indoor and outdoor unit buses, and the centralized controller is also connected with the central humidifier;
as shown in fig. 2, the central humidifier and the centralized controller for controlling the central humidifier are connected to the air conditioner indoor and outdoor unit bus. For example, when the indoor unit room at address 0 has a humidification demand, the centralized controller is used to open the valve 2 of the central humidifier at address 0, while keeping the other valves in a closed state. When the indoor unit at address 0 detects the room humidity at any time and sends the humidity to the outdoor unit for control, the central humidifier and the centralized controller can monitor the room humidity of the room, and the room humidity and the set humidity are used as the basis for judging whether the central humidifier needs to continue to humidify.
