Title:
REFRIGERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/103295
Kind Code:
A1
Abstract:
Provided is a refrigeration device comprising a refrigeration cycle including an ejector. The ejector 41a sucks a refrigerant gas by the ejection of a high-pressure refrigerant liquid obtained by condensing a high-pressure refrigerant gas emitted from a compressor 20, and increases the pressure of a mixed fluid thereof. A gas-liquid separator 33a separates the mixed fluid into gas and liquid, and sends the separated refrigerant gas to the compressor 20. A heat exchanger 34a exchanges heat between a fluid to be cooled and the refrigerant liquid separated by the gas-liquid separator 33a, and the generated refrigerant gas is sucked by a suction opening in the ejector 41. A liquid level adjustment valve 342a adjusts the flow rate of the refrigerant liquid on the basis of the liquid level of the refrigerant liquid in the heat exchanger 34a. A flow rate adjustment unit 411 adjusts the flow rate of the high-pressure refrigerant liquid supplied to the ejector 41a on the basis of the liquid level in the gas-liquid separator 33a.
