Abstract

The present invention relates to an air conditioner, comprising: a refrigerating device including a compressor, a plurality of heat exchangers for exchanging heat with the refrigerant supplied by the compressor, and a plurality of heat exchangers arranged between the plurality of heat exchangers. an electric expansion valve and an accumulator provided between the heat exchanger and the compressor; and a control unit that performs control to close the plurality of electric expansion valves when the operation of the compressor is stopped to prevent The refrigerant between the electric expansion valve is contained in the accumulator. Thus, the present invention relates to an air conditioner, and more particularly, to an air conditioner having an improved structure to reduce the size of an accumulator.

Description

technical field [0001] The present invention relates to an air conditioner, and more particularly to an air conditioner whose structure is improved so that the size of an accumulator can be reduced. Background technique [0002] Generally, an air conditioner is a device for controlling indoor air temperature of a building, and is installed in buildings such as houses, offices, and factories. And, the air conditioner includes a freezing device provided therein for controlling indoor air temperature. [0003] This refrigerating apparatus includes a heat exchanger and the like, such as a compressor, a condenser, and an evaporator connected to the compressor. [0004] An example of an air conditioner with a refrigeration device is described in Korean Patent Publication No. 2004-0074544. Such a conventional air conditioner includes: an accumulator that divides the low-temperature and low-pressure refrigerant generated by the evaporator into liquid and gas refrigerant, and allow...
