Abstract

PURPOSE: To obtain an optimum refrigerating cycle to meet a load by controlling an output frequency of an inverter in response to an air conditioning load, and selectively supplying an output of the inverter and a commercial power source output to a compressor in response to an air conditioning load. CONSTITUTION: At the time of operating, a controller 50 detects an air conditioning load in response to a detected pressure of a pressure sensor 40, turns ON contactors 51, 52 in the case of the low load to maintain a switching unit 30 in a non-operating state, further controls an output frequency F of an inverter 20 to inverter drive, a compressor 1. And, when the frequency becomes a highest output frequency Fmax as the air conditioning load is increased, a contactor 53 is closed, the unit 30 is operated, the compressor 1 is switched to a commercial power source drive, and the compressor 2 is inverter driven. But, as the conditioning load is increased, the frequency F is increased, while as the load is decreased, the frequency F is decreased. When it becomes a lowest output frequency Fmin, the contactor 53 is opened, the unit 30 is stopped, the inverter drive of the compressor 2 is stopped to switch the compressor 1 to an inverter drive.
