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.

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 refrigeration system, an evaporator and a gas-liquid separator are received in a common casing, so that the gas-liquid separator and the evaporator are placed close to each other. Thus, it is possible to limit heat absorption of the liquid phase refrigerant from the atmosphere to reduce the heat loss upon discharge of the refrigerant from the gas-liquid separator. Also, it is possible to reduce pressure loss in a refrigerant passage between the gas-liquid separator and the evaporator.

摘要： In a refrigerant cycle system with an ejector pump, refrigerant to be introduced into a nozzle of the ejector pump is heated in a heat exchanger using waste heat from a vehicle engine as a heating source, and any one of a first mode, a second mode and a third mode can be selectively set based on a thermal load of an evaporator. In the first mode, refrigerant circulates from the evaporator toward a radiator only by the ejector pump. In the second mode, refrigerant circulate from the evaporator toward the radiator only by a compressor. Further, in the third mode, refrigerant circulates from the evaporator toward the radiator by using both the ejector pump and the compressor. Accordingly, the waste heat can be effectively recovered while a flow resistance of the refrigerant can be restricted.
