WIPO Patent Application WO/2018/154628
Kind Code:
A1
Abstract:
Provided is an air conditioning device comprising: a refrigerant circuit in which a compressor, a heat source-side heat exchanger, an expansion part, and a refrigerant and heat-medium heat exchanger are connected by a refrigerant piping, and through which a refrigerant circulates; and a heat medium circuit in which a pump, the refrigerant and heat-medium heat exchanger, and a load-side heat exchanger that exchanges heat with air in an air conditioning space are connected by a heat medium piping, and through which the heat medium circulates. The air conditioning device further includes: a separation section which is provided outside the air conditioning space, in a portion of the heat medium piping through which the heat medium that has flown out of the refrigerant and heat-medium heat exchanger passes before flowing into the load-side heat exchanger, and which separates the refrigerant from the heat medium; and a discharge section which is connected to the separation section, and which discharges the refrigerant separated by the separation section to the outside of the air conditioning space.
