Abstract: An improved water cooled air conditioner having a compressor, an evaporator, a cooling fan, a low pressure pipe, a high pressure pipe, a radiator, a cooling motor, and a condenser is provided. The apparatus is characterized in that the heat exchanging efficiency between the cooling water and the refrigerant is highly enhanced thereby intensifying the cooling effect and increasing the temperature of the cooling water flowing out of the apparatus to an acceptable degree for use as residential hot water. Further, the heated water from the radiator may be sprayed on to the external surface of the radiator to provide evaporative cooling thereof.

Abstract: This invention relates to an air conditioning apparatus and in particular to one including a compressor, an evaporator, a cooling fan, a low pressure pipe, a high pressure pipe, a radiator, a cooling motor, and a condenser. The apparatus is characterized in that the heat exchanging efficiency between the cooling water and the refrigerant is highly enhanced, thereby intensifying the cooling effect and increasing the temperature of the cooling water flowing out of the apparatus to an acceptable degree for residential hot water. Further the radiator may be separated from the apparatus thus making it suitable for use in varied applications.
