Title:
EJECTOR REFRIGERATION CYCLE
Document Type and Number:
WIPO Patent Application WO/2014/203460
Kind Code:
A1
Abstract:
In the present invention, a storage tank (19) that stores the excess refrigerant of the cycle as liquid phase refrigerant is disposed between the exit side of a first evaporator (15) and the entrance side of the nozzle (18a) of an ejector (18), the liquid phase refrigerant stored at the storage tank (19) is mixed with gas phase refrigerant flowing out of the first evaporator (15), and the refrigerant in a gas-liquid two-phase state is caused to flow into the nozzle (18a). As a result, delayed condensation in the nozzle (18a) is suppressed, an increase in dryness (x) of the mixed refrigerant resulting from intake refrigerant taken in from a second evaporator (17) and injected refrigerant injected from the nozzle (18a) is suppressed, and the coefficient of performance (COP) of an ejector refrigeration cycle (10b) is sufficiently increased.
