PURPOSE: An air conditioner not having an outdoor device is provided to improve cooling efficiency by covering a refrigerant feeding pipe of a condenser with a cooling jacket and to contact cooling water to the refrigerant feeding pipe by flowing cooling water inside the cooling jacket. CONSTITUTION: A condenser(13) of an air conditioner has a refrigerant feeding pipe to exhaust hot refrigerant inputted from an evaporator(14) through a compressor(12) into low-temperature. A cooling jacket covers the refrigerant feeding pipe. Cooling water flows in the cooling jacket. refrigerant of the refrigerant feeding pipe feeds to a reverse direction with cooling water of the refrigerant jacket. Cooling fins are formed to the cooling jacket to facilitate heat exchange with refrigerant of the refrigerant feeding pipe. A feedback pipe is formed apart from the cooling jacket to feed back cooling water. Thereby, cooling efficiency is improved and cooling water is recycled. A fan or an exhausting hose are not necessary to exhaust hot air outside. |
