Patent ID: 7484379

Claim:
An air conditioner, comprising an air conditioner casing, in which air flows, the air conditioner casing having an opening; an evaporator arranged in the air conditioner casing to cool air flowing in the air conditioner casing; an evaporator-side connector which protrudes from the evaporator toward an outer side of the air conditioner casing through the opening, the evaporator-side connector having therein a refrigerant introduction passage, through which refrigerant is introduced into the evaporator, and a refrigerant discharge passage, through which refrigerant is discharged from the evaporator, the air conditioner casing having a surrounding wall member, which encircles the evaporator-side connector and is erected at the air conditioner casing so that a surrounding-shaped tip portion thereof projects beyond an end surface of a protrusion side of the evaporator-side connector; a refrigerant decompression member which is arranged apart from the evaporator to decompress refrigerant; a piping group having an introduction pipe, through which refrigerant decompressed by the refrigerant decompression member is introduced into the refrigerant introduction passage, and a discharge pipe, through which refrigerant discharged via the refrigerant discharge passage flows; a piping-side connector, which is arranged at an opposite end of the piping group to the refrigerant decompression member and connected with the evaporator-side connector to respectively communicate interiors of the introduction pipe and the discharge pipe with the refrigerant introduction passage and the refrigerant discharge passage; and a heat-insulating seal member which covers a whole area between the surrounding wall member and outer peripheral surfaces of the introduction pipe and the discharge pipe of the piping group.
