Document Type and Number:
WIPO Patent Application WO/2019/130383
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an air conditioning device that ensures safety with regard to the leakage of a refrigerant. This air conditioning device comprises: a refrigerant circuit including a compressor, a heat source-side heat exchanger which is a water-cooled heat exchanger, a throttling section, and a load-side heat exchanger, all being connected to each other by a piping through which a refrigerant circulates; a load-side blower that supplying air inside the room to the load-side heat exchanger; a casing that accommodates the refrigerant circuit and the load-side blower; a refrigerant detection sensor that detects any refrigerant that has leaked from the refrigerant circuit; and a control device that controls the compressor and the load-side blower. The refrigerant is a flammable refrigerant having a global warming potential of 750 or less.
