refrigeration cycle type has ejector

A refrigeration cycle of the ejector type including a compressor (11), a heat emitting device (13), an ejector (14), and a first evaporation device (15), which are connected in a circuit for forming a refrigeration cycle. A bypass conduit (16) is arranged between an inlet port and an outlet port of the ejector (14), so that a portion of the refrigerant is diverted to flow through the bypass duct (16). A second evaporation device (18) is provided in the bypass conduit (16). An internal heat exchanger (21) is further arranged between an output side of the heat emitting device (13) and the input side of the ejector (14), so that the enthalpy of the high-pressure refrigerant from the heat emitting device (13) is reduced, to thereby increase an enthalpy difference between the inlet side and the outlet side of the first and second evaporation means (15, 18). Accordingly, the cooling capacity by the two evaporation devices can be improved.
