Title:
REFRIGERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/139594
Kind Code:
A1
Abstract:
Provided is a refrigeration device in which a refrigerant circuit (10) is configured by connecting a compressor (21), a first heat exchanger (23), an expansion mechanism (24), and a second heat exchanger (31). The refrigerant circuit (10) comprises a four-way switching valve (22) for switching between a first state in which refrigerant is circulated through the compressor (21), the first heat exchanger (23), the expansion mechanism (24), and the second heat exchanger (31) in this order and a second state in which refrigerant is circulated through the compressor (21), the second heat exchanger (31), the expansion mechanism (24), and the first heat exchanger (23) in this order. The four-way switching valve (22) is a rotary four-way switching valve that switches between the first state and the second state by causing a valve body (43) to rotate with respect to a valve case (44).
