摘要： In an ejector cycle with an ejector including a nozzle for decompressing refrigerant, a control unit controls an air blowing amount of an evaporator fan so that a flow speed of refrigerant flowing in an evaporator becomes in a predetermined flow speed range. Therefore, it can prevent a large amount of lubrication oil from staying in the evaporator, and thereby the lubrication oil can sufficiently returns to a compressor. For example, the control unit includes a determining means for determining the predetermined flow speed range based on at least one of an atmosphere temperature of a condenser, a temperature of air supplied to the evaporator and a flow amount of refrigerant discharged from the compressor.

摘要： An air conditioning system for a vehicle has a cool storage heat exchanger for continuing cooling operation with stored cooling energy during a compressor is stopped due to a temporal stop of an engine for the vehicle. Cooling energy is stored in the cool storage material of the cool storage heat exchanger during a normal cooling operation during which the compressor is operated by the engine. When the vehicle stops, for example before a traffic lamp, and thereby the compressor is not operated, an ejector is operated to circulate the refrigerant from the cool storage heat exchanger to an evaporator so that the cooling operation can be continued.

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.
