In order to better understand the above technical scheme, in conjunction with appended figures and specific embodiments to upper
Technical solution is stated to be described in detail.
Embodiment one
Fig. 1 is the flow chart of the dewing-proof method of the air conditioner of the embodiment of the present application one.
In one embodiment of the application, as shown in Fig. 2, air conditioner can include: input power, electric-control system, compression
Machine, outdoor heat exchanger, indoor heat exchanger, outdoor fan, indoor fan and restricting element.Wherein, outdoor fan corresponds to outdoor and changes
Hot device setting, indoor fan correspond to indoor heat exchanger setting, and one end of compressor is connected with one end of outdoor heat exchanger, and outdoor is changed
