Title:
AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/170734
Kind Code:
A1
Abstract:
An air conditioning device according to the present disclosure comprises a refrigerant circuit having a compressor, a heat-source-side heat exchanger that functions as an evaporator, a refrigerant flow path switching device, a load-side heat exchanger that functions as a condenser, and a load-side diaphragm device. The air conditioning device comprises bypass piping for guiding refrigerant discharged from the compressor to the heat-source-side heat exchanger, a first opening/closing device provided to the bypass piping, and a control device. The compressor, the heat-source-side heat exchanger, the refrigerant flow path switching device, the bypass piping, and the first opening/closing device are mounted in an outdoor unit. During defrosting of the heat-source-side heat exchanger, the control device sets a flow path in the refrigerant flow path switching device as a flow path through which the refrigerant discharged from the compressor flows into the load-side heat exchanger, transitions the first opening/closing device from a closed state to an open state, transitions the load-side diaphragm device from an open state to a closed state, and causes the refrigerant discharged from the compressor to flow from the bypass piping into the heat-source-side heat exchanger.
