Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/170743
Kind Code:
A1
Abstract:
This refrigeration cycle device comprises: a compressor; a flow path switching device; an indoor heat exchanger; a throttle device; a plurality of flow control valves; and a refrigerant circuit to which a plurality of outdoor heat exchangers are connected by piping and in which a refrigerant circulates. The refrigerant circuit is configured such that the refrigerant flows in parallel through each of the plurality of outdoor heat exchangers during a heating operation, and is configured such that the refrigerant flows in series through some of the plurality of outdoor heat exchangers serving as the upstream side and the remaining plurality of outdoor heat exchangers that serve as the downstream side during a cooling operation and during a defrosting operation. A temperature sensor is provided to piping on an outlet side of an outdoor heat exchange serving as the downstream side during the cooling operation and during the defrosting operation.
