The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

In a conventional indoor air conditioner, a heat exchange assembly and a fan module are included.

The heat exchange assembly is an indoor heat exchanger and can be used as a condenser and an evaporator.

The fan module is used as a driving unit of air flow and used for driving indoor air to circulate air, and the indoor air conditioner is used for exchanging heat and air for an indoor space.

In practical applications, the air conditioner system as a whole includes an indoor air conditioner, which refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, and an outdoor air conditioner, which is connected to the indoor air conditioner installed in an outdoor space through a pipe, the air-indoor air conditioner includes the outdoor heat exchanger, and an expansion valve may be provided in the outdoor air conditioner.
