Description

このように、ガスクーラ２を通過した後の冷媒温度および冷媒圧力に基づいて第一絞り部３の開度を調整するようにしたので、その後の冷媒の流動に支障を来すことのない冷媒圧力を臨界圧力以下に抑えることができる。したがって、内部熱交換器（ここでは、内管１７）に耐圧構造を採用する必要がなくなる。この結果、内部熱交換器４を小型で安価に製作することが可能となる。特に、内管１７を薄くすることにより、各流路の冷媒間での熱交換効率を高めることができる。 Thus, since so as to adjust the opening degree of the first throttle portion 3 based on the refrigerant temperature and refrigerant pressure after passing through the gas cooler 2, have name cold to hinder the flow of subsequent refrigerant The refrigerant pressure can be suppressed below the critical pressure. Therefore, it is not necessary to adopt a pressure resistant structure for the internal heat exchanger (here, the inner tube 17). As a result, the internal heat exchanger 4 can be manufactured in a small size and at low cost. In particular, by making the inner pipe 17 thinner, the heat exchange efficiency between the refrigerants in each flow path can be improved.
