Title:
REFRIGERATION CYCLE AND REFRIGERATION SHOWCASE
Document Type and Number:
WIPO Patent Application WO/2013/140918
Kind Code:
A1
Abstract:
This refrigeration cycle is configured by including: a compressor (1) that compresses a coolant; a condenser (2) that condenses the coolant compressed by the compressor (1); a first expansion valve (4) and a second expansion valve (6) that each expand the coolant branched downstream from the condenser (2); a first evaporator (5) that evaporates the coolant expanded by the first expansion valve (4); a second evaporator (7) that evaporates at least part of the coolant expanded by the second expansion valve (6); a heat exchanger (3) that evaporates at least part of the coolant expanded by the second expansion valve (6) by heat exchanging same with the coolant condensed by the condenser (2); and an injector (8) that uses the coolant evaporated by the second evaporator (7) and the heat exchanger (3) as a drive flow, uses the coolant evaporated by the first evaporator (5) as a suction flow, mixes the drive flow and the suction flow, and supplies same to the compressor (1).
