摘要： In a vapor-compression refrigerant cycle having an ejector, a mixture refrigerant of a first refrigerant and a second refrigerant is used. When the mixture refrigerant is decompressed and expanded in a nozzle of the ejector, the first refrigerant has an adiabatic heat drop that is larger than that of the second refrigerant. Further, the second refrigerant has an evaporation latent heat that is larger than that of the first refrigerant. In a gas-liquid separator, a gas-phase amount of the first refrigerant is made larger than that of the second refrigerant, and a liquid-phase amount of the second refrigerant is made larger than that of the first refrigerant. For example, the first refrigerant is propane, and the second refrigerant is butane. Accordingly, expansion energy recovered in the nozzle can be effectively converted to pressure energy in a pressure increasing portion of the ejector while cooling capacity of an evaporator can be improved.

摘要： The present invention has an object to provide an ejector cycle and an ejector, according to which a sufficient cooling performance can be obtained even when the input amount of the refrigerant to the ejector is decreased. A passage changeover means having a bypass channel is formed in an ejector. The passage changeover means opens the bypass channel in a bypass cooling operation, in which an input amount of the refrigerant to the ejector is decreased due to a low ambient temperature, and so on. Accordingly, in this bypass cooling operation, the refrigerant from an outside heat exchanger to the ejector bypasses an ejector nozzle and flows to an evaporator through the bypass channel.

摘要： A heat exchanger includes a plurality of fluid passages through which a heat-exchanger fluid including a liquid-phase fluid passes, a tank disposed above inlet parts of the fluid passages for distributing a flow of the heat-exchanger fluid to the fluid passages, and a retention member that is located above the inlet parts within the tank, for temporarily storing therein the liquid-phase fluid flowing into the tank. The retention member is constructed such that the liquid-phase fluid overflowing from the retention member falls toward the inlet part. Accordingly, the heat-exchanger fluid can be uniformly distributed into the fluid passages from the tank. For example, the heat exchanger can be used as an evaporator for a refrigerant cycle device having an ejector.
