<p>PURPOSE: To increase heating effect even when the outer air temperature is low and to recover oil smoothly to a compressor by preventing liquid refrigerant from standing in an accumulator. CONSTITUTION: A dual-purpose air conditioner comprises means for supplementing refrigerant with heat before flowing into a compressor, preferably a heater 15 disposed in an accumulator 5, a superheating degree sensing means for controlling the heat supplementing means to keep a specified degree of heating, preferably including a suction pressure sensor and a suction temperature sensor, and a control means including a microcomputer.</p> |
