    摘要: The internal heat exchanger 15 for exchanging heat between the refrigerant, which has passed through the gas cooler 11 for cooling the refrigerant, and the refrigerant, which is before the suction into the compressor 10, are arranged in a space on the rear side of the fan shroud 32 with respect to the vehicle and on the outer circumferential side of the blower 31. As a space which has not been conventionally put into effective use is utilized, it is unnecessary to ensure a new space for arranging the internal heat exchanger 15 in the engine compartment.

    摘要: A gas-liquid separator (accumulator) is arranged at a refrigerant suction side of a compressor of a refrigerant cycle system mounted in a vehicle. The gas-liquid separator includes a gas-liquid separation portion for separating refrigerant into gas refrigerant and liquid refrigerant, and a liquid refrigerant storage portion for storing therein the separated liquid refrigerant. In the gas-liquid separator, the gas-liquid separation portion is arranged approximately vertically, and the liquid refrigerant storage portion is arranged approximately horizontally with respect to the approximately vertically arranged gas-liquid separation portion. Therefore, mounting performance of the gas-liquid separator in the vehicle can be effectively improved while gas-liquid separation can be accurately performed.

    摘要: In an ejector cycle with an ejector including a nozzle for decompressing refrigerant, a variable throttle is disposed upstream from the nozzle of the ejector to decompress and expand high-pressure refrigerant flowing from a radiator. For example, the variable throttle decompresses and expands the high-pressure refrigerant in a gas-liquid two-phase state at an upstream position from the nozzle of the ejector. The variable throttle controls a throttle opening degree so that a refrigerant super-heating degree at a refrigerant outlet side of an evaporator or at a refrigerant suction side of a compressor becomes in a predetermined range. Accordingly, the ejector cycle has an improved nozzle efficiency and an improved ejector efficiency in a wide load variation range of the ejector cycle.
