<p><P>PROBLEM TO BE SOLVED: To provide an air conditioning device capable of preventing accumulation of liquid refrigerant in a compressor with an inexpensive constitution. <P>SOLUTION: In this air conditioning device where an outdoor machine 1 having the compressor 2 provided with a crank case 11, an outdoor heat exchanger 3, and an outdoor air temperature detecting device 10 detecting an outdoor air temperature, and an indoor machine 12 having an indoor heat exchanger 14 are connected with each other, power distribution to the crank case heater 11 is controlled according to the outdoor air temperature and a lapsed time from the stop of the compressor 2 in stopping the compressor 2, so that, for example, a time to the start of power distribution to the crank case heater 11 from the stop is shortened when the outdoor air temperature in stopping the compressor 2 is low, and a time to the start of power distribution to the crank case heater 11 from the stop is elongated (or not distribute power) when the outdoor air temperature in stopping the compressor 2 is high, thus the accumulation of liquid refrigerant inside of the compressor 2 can be effectively prevented, the compressor 2 is prevented from being damaged, and the reliability can be improved. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
