OUTDOOR AIR CONDITIONING APPARATUS

WIPO Patent Application WO/2022/075248

A1

The present invention presents an air conditioning apparatus with which it is possible to prevent the compressor oil quantity from falling below a required quantity in a compressor (10) in association with outdoor use. This outdoor air conditioning apparatus (100) is used outdoors, the apparatus (100) comprising a refrigerant circuit (20) and a control device (70). The refrigerant circuit (20) has a compressor (10), a heat-source-side heat exchanger (40), and a use-side heat exchanger (30). In the refrigerant circuit (20), a refrigerant circulates through the compressor (10), the heat-source-side heat exchanger (40), and the use-side heat exchanger (30), whereby a refrigeration cycle is carried out. The control device (70) activates the compressor (10) and executes a refrigeration cycle operation for causing the refrigerant circuit (20) to carry out the refrigeration cycle. The control device (70): executes a first pre-operation control (first control) in which, after the compressor (10) is activated for a prescribed first period, the compressor (10) is stopped for a prescribed second period that is longer than the first period; and initiates the refrigeration cycle operation after the first pre-operation control has ended.
