Title:
HEAT RECOVERY TYPE REFRIGERATION UNIT
Document Type and Number:
Japanese Patent JP2015075258
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To secure a flow rate of a refrigerant flowing in a refrigerant cooler and thus enable cooling of an electric component, even when heat recovery is performed between use side heat exchangers in installing the refrigerant cooler for cooling the electric component in a heat recovery type refrigeration unit that enables heat recovery between the use side heat exchangers.SOLUTION: A heat recovery type refrigeration unit 1 includes a compressor, heat source side heat exchangers 24, 25, 35 and a plurality of use side heat exchangers 52a, 52b, 52c, 52d, and can recovery heat between the use side heat exchangers by sending a refrigerant from the use side heat exchanger functioning as a radiator for the refrigerant to the use side heat exchanger functioning as an evaporator for the refrigerant. A part 35 of the heat source side heat exchangers 24, 25, 35 is made to function as a precooling heat exchanger in which a high-pressure gas refrigerant discharged from the compressor 21 flows all the time, and a refrigerant cooler 36 for cooling an electric component is connected to the downstream side of the precooling heat exchanger 35.
