For example, in summer, when the outdoor air temperature is too high or the humidity is too high, the opening degree of the first damper 311 or the second damper 321 is reduced, or the first damper 310 or the second damper 320 is completely closed, so as to reduce the fresh air flow rate. When the humidity of the outdoor air is too high, the second air port 320 can be kept at a normal opening, so that the fresh air passes through the heat exchanger 200 for refrigeration, and meanwhile, the fresh air is dehumidified and then enters the mixing cavity 102. Therefore, enough fresh air is introduced, and the problem of overhigh humidity of the fresh air is solved. When the temperature of the fresh air is low and the humidity is proper, a fresh air running mode can be considered, and the fresh air flow is increased.
Of course, the first fan 500, the second fan 700, the third damper 131, and the like are also controlled by the controller 900, and detailed description thereof is omitted.
The user accessible remote controller sets for the operating mode, and the remote control signal that the remote controller sent can give the controller 900 in the suspension type air conditioner indoor set in real time, and controller 900 can be according to remote control signal, and the control suspension type air conditioner indoor set gets into corresponding operating mode.
