The present invention relates to a compressor for an air conditioner capable of preventing the introduction of liquid refrigerant into a compressor by turning on and off of the compressor. The compressor auxiliary device of an air conditioner according to the present invention includes a compressor, a four-way valve, an outdoor heat exchanger, and an expansion device. The refrigerant is circulated in the order of equipment, indoor heat exchanger, accumulator, and compressor, and cooling operation is performed. In the air-conditioning and air-conditioning combined air conditioner in which the operation is performed, the accumulator determines whether or not the current outside air temperature is a cold temperature. According to the result, a thermistor which is a temperature sensing means is attached to control the flow of the liquid refrigerant, and if the current outside air temperature sensed by the thermistor is a cold temperature, the cold water is turned off so that a certain amount of the liquid refrigerant remains. An auxiliary accumulator is disposed in front of the radar.
