REFRIGERATION DEVICE AND TEMPERATURE CONTROL DEVICE

WIPO Patent Application WO/2018/212101

A1

[Problem] To efficiently cool a plurality of objects to be temperature-controlled or a space while controlling device size. [Solution] This refrigeration device comprises a first refrigeration circuit, a supercooling circuit, and a second refrigeration circuit. The supercooling circuit has: a supercooling bypass channel by which a compressor and a portion located on the downstream side of a condenser and on the upstream side of a first expansion valve in the first refrigeration circuit communicate; a supercooling control valve; and a supercooling heat exchanger that is provided on the downstream side of the supercooling control valve in the supercooling bypass channel and that cools refrigerant flowing through a portion that is further on the downstream side than the location of the connection with the supercooling bypass channel in the first refrigeration circuit. The second refrigeration circuit has: a branching channel that branches from a portion further upstream than the location of the connection with the supercooling bypass channel in the first refrigeration circuit; a second expansion valve that is provided in the branching channel; and a second evaporator that is provided on the downstream side of the second expansion valve in the branching channel and that is for evaporating the refrigerant flowing out from the second expansion valve.
