Abstract (en)
Disclosed is an air conditioner. The air conditioner a main compressor for compressing a refrigerant; a four-way valve disposed at a discharge side of the main compressor and switching a fluid path; an outdoor heat exchanger having one side connected with the four-way valve; an indoor heat exchanger having one side connected with the outdoor heat exchanger and the other side connected with the four-way valve; an expansion valve disposed between the outdoor heat exchanger and the indoor heat exchanger; and an auxiliary compression unit for reducing the load on the main compressor. Accordingly, since the load on the main compressor decreases, efficiency and reliability of the main compressor are enhanced and noises are reduced. In addition, an instrumental part such as a bearing inside the main compressor is not subject to abrasion and high heat damage to a motor unit is prevented.
