The room is humidified independently or the same room is centrally humidified, and a multi-connected air-conditioning system with a humidification function is realized, and the structure is simple and the cost is low. At the same time, the steam sent out by the humidifying device 100 is a pure gas, which does not need to be filtered compared with the humid air, which further simplifies the structure and saves the cost.

Referring to FIG. 2 to FIG. 6 , a multi-connected air-conditioning system with four air-conditioning indoor units 300 is taken as an example. Of course, the present invention is not limited to the number of air-conditioning indoor units 300 shown in the figures. The structure of pipeline 400 can have the following several embodiments:

In the first embodiment of the present application, the humidifier 100 is provided with a plurality of exhaust holes 111, and the exhaust holes 111 are provided in one-to-one correspondence with the air conditioner indoor unit 300, and the pipeline 400 includes a plurality of the steam pipes. 401 , two ends of each steam pipe 401 are respectively connected to each of the exhaust holes 111 and each of the air conditioner indoor units 300 .
