Title:
REFRIGERATION CYCLE AND REFRIGERATION SHOWCASE
Document Type and Number:
WIPO Patent Application WO/2013/140992
Kind Code:
A1
Abstract:
The present invention pertains to a refrigeration cycle comprising an ejector, and a refrigeration showcase. This refrigeration cycle and refrigeration showcase are configured by including: a compressor (1); a condenser (2); an evaporator (5) that evaporates refrigerant condensed by the condenser (2); an ejector (7) that uses at least part of the refrigerant condensed by the condenser (2) as drive flow and refrigerant evaporated by the evaporator (5) as suction flow, mixes the drive flow and the suction flow, and supplies same to the compressor (1); an oil separator (8) provided between the compressor (1) and the condenser (2), that separates compressor (1) lubrication oil from the refrigerant; and a first flow path (P) that supplies at least part of the lubricating oil separated by the oil separator (8), as part of the drive flow for the ejector (7). As a result, the compressor lubricating oil can be used as part of the drive flow for the ejector, so the drive flow flowrate can be increased, and the efficiency of the refrigeration cycle can be improved.
