ABSTRACT:
Improvements in a heating system which heats a fluid medium by a heat exchanger and delivers it to an indoor coil or coils for space heating. Refrigerant, such as fluorohydrocarbons for refrigerators, is utilized as the heating medium. The heat exchanger is supplied with heat from a heat source, such as hot water from a boiler, at a temperature higher than that of air around the exchanger. The refrigerant in liquid form is heated while being vaporized in the heat exchanger at a pressure greater than the saturation pressure corresponding to the ambient air temperature. The medium thus gasified to a high pressure and temperature is drawn into a circulating pump and then delivered to the indoor coil or coils, where it is condensed to a liquid with heat dissipation. In this way a great heating capacity is attained with the heating medium at a low rate of circulation. The suction of high-pressure heating medium enables the circulating pump of a small capacity to accomplish not only a high rate of transfer of the heating medium but also a decrease of the compression ratio. These beneficial effects combine to permit substantial reduction of the pump power consumption.
