ABSTRACT:
A heat pump installation including a condenser, a motor-compressor, an evaporator, and a subcooler to subcool the refrigerant flowing from the condenser before it enters the evaporator. The motor-compressor is mostly immersed in a static liquid contained within an inner tank. Preferably, the static liquid contains a top layer of oil to prevent evaporation. The static liquid helps to ensure the cool and quiet operation of the motor-compressor. Surrounding the inner tank is an outer tank which provides a cylindrical chamber wherein circulating liquid such as water flows. Immersed within the circulating water is the condenser. The circulating water withdraws heat from the inner tank and the condenser. The subcooler includes a housing which contains and directs the flow of the circulating water before it enters the cylindrical chamber. Immersed within the circulating water of the subcooler housing is a refrigerant subcooling coil. The circulating water serves to subcool the refrigerant flowing in the subcooling coil before the refrigerant enters the evaporator thereby improving the efficiency of the heat pump system. If the invention is employed to heat potable water a separate heating coil is provided which is immersed in the circulating water contained in the cylindrical chamber. The invention further provides a unique condenser and method of producing the same.
