    摘要： A refrigerant pipe connected to a suction side of a compressor and a refrigerant pipe connected to a discharge side of the compressor are integrated into one body. A refrigerant pipe connected to an inlet side of a condenser and a refrigerant pipe connected to an outlet side of the condenser are integrated into one body. A refrigerant pipe connected to an inlet side of a decompressor and a refrigerant pipe connected to an outlet side of the temperature detecting portion are integrated into one body. In these piping structures, a double pipe structure and a double pipe joint structure are adopted in which an inner pipe for circulating high pressure fluid and an outer pipe for circulating low pressure fluid are formed separate from each other and the respective end portions of the pipes are joined to a joint member by plastically deforming the pipes.

    摘要： In a vehicle air conditioner having front and rear air conditioning units, a refrigerant cycle includes front and rear evaporators for cooling air in a cooling mode, a hot-gas bypass passage through which hot-gas refrigerant discharged from a compressor flows into the front evaporator while bypassing a condenser in a heating mode, and a fixed throttle between the condenser and the front evaporator for decompressing refrigerant flowing from the condenser in the cooling mode. Further, a refrigerant outlet side of the fixed throttle and a refrigerant outlet side of the hot-gas bypass passage are joined to a refrigerant pipe, and a refrigerant outlet of the refrigerant pipe is connected to a refrigerant inlet of the front evaporator. Therefore, a refrigerant pipe structure of the refrigerant cycle can be made simple.
