Abstract
A compressor compresses a refrigerant. A radiator cools the refrigerant compressed by the compressor. An expansion valve receives the refrigerant from the radiator to depressurize and expand the refrigerant. An evaporator evaporates the refrigerant expanded by the expansion valve to cool air passing through the evaporator. An accumulator receives the refrigerant from the evaporator to separate the refrigerant into a gas-phase refrigerant and a liquid-phase refrigerant. The accumulator includes an insertion portion inserted in the accumulator and included in a pipe arranged from the radiator to the expansion valve for exchanging heat between a refrigerant flowing through the insertion portion and at least the liquid-phase refrigerant in the accumulator.
Claims8
A vehicular air-conditioner comprising:
- a compressor for compressing a refrigerant;
- a radiator for cooling the refrigerant compressed by the compressor;
- an expansion valve for receiving the refrigerant from the radiator to depressurize and expand the refrigerant;
- an evaporator for evaporating the refrigerant expanded by the expansion valve to cool air passing through the evaporator;
- and
- an accumulator for receiving the refrigerant from the evaporator to separate the refrigerant into a gas-phase refrigerant and a liquid-phase refrigerant,
- the accumulator including an insertion portion inserted in the accumulator and included in a pipe arranged from the radiator to the expansion valve for exchanging heat between a refrigerant flowing through the insertion portion and at least the liquid-phase refrigerant in the accumulator.
