Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO2017010007
Kind Code:
A1
Abstract:
An air conditioner is provided with: a refrigeration cycle circuit for circulating a refrigerant through pipelines connecting a compressor, a heat-source-side heat exchanger that is divided into a plurality of regions for performing heat exchange between the refrigerant and outside air, a refrigerant flow path switching device for changing the direction in which the refrigerant flows through the heat-source-side heat exchanger divided into the plurality of regions, a decompressor, and a load-side heat exchanger; a receiver for storing the refrigerant, the receiver branching from the refrigerant pipeline between the heat-source-side heat exchanger and the load-side heat exchanger, and being provided partway along the refrigerant pipeline linked to the intake side of the compressor; a first valve branching from the refrigerant pipeline between the heat-source-side heat exchanger and the load-side heat exchanger, the first valve being provided to the refrigerant pipeline connected to the flow-in side of the receiver; a second valve connected to the flow-out side of the receiver, the second valve being provided to the refrigerant pipeline linked to the flow-in side of the compressor; and a control device for using only a part of the heat-source-side heat exchanger when the air-cooling load of the load-side heat exchanger is less than a predetermined value, and controlling the storage of refrigerant in the receiver.
