Title:
EJECTOR-TYPE REFRIGERATION CYCLE
Document Type and Number:
Japanese Patent JP2010112691
Kind Code:
A
Abstract:

To stably operate an ejector-type refrigeration cycle even when a flow rate of driving flow passing through a nozzle section of an ejector changes.

A second compressing mechanism 21a is provided between a suction-side evaporator 16 of which a refrigerant outlet is connected with a refrigerant suction port 13b side of the ejector 13, and the refrigerant suction port 13b. Thus even under an operation condition such that the suction capability of the ejector 13 reduces with reduction in the flow rate of the driving flow of the ejector 13, the suction capability of the ejector 13 can be assisted by the second compressing mechanism 21a. Consequently, even when the flow rate of the driving flow changes, the ejector-type refrigeration cycle can be stably operated with high COP.
