Title:
HEAT RECOVERY TYPE REFRIGERATION DEVICE
Document Type and Number:
Japanese Patent JP2015049000
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To deal with a case in which a thermal load of a plurality of utilization side heat exchangers is small as a whole, while suppressing deterioration of operation performance, in a heat recovery type refrigeration device including a compressor, a plurality of heat source side heat exchangers and the plurality of utilization side heat exchangers and capable of performing heat recovery between the utilization side heat exchangers.SOLUTION: A heat recovery type refrigeration device (1) includes: a compressor (21); a plurality of heat source side heat exchangers (24, 25); and a plurality of utilization side heat exchangers (52a, 52b, 52c, 52d). Heat recovery can be performed between the utilization side heat exchangers by feeding a refrigerant from the utilization side heat exchanger functioning as a radiator of the refrigerant to the utilization side heat exchanger functioning as an evaporator of the refrigerant. Then, the plurality of heat source side heat exchangers (24, 25) include: the first heat source side heat exchanger (24); and the second heat source side heat exchanger (25) having heat exchange capacity 1.8-4.0 times as much as that of the first heat source side heat exchanger (24).
