Abstract
A condenser receives hot compressed refrigerant from the heat pump compressor and transfers heat to water in water heater, refrigerant flows from the condenser through a pressure reducer to an evaporator coil in which baffles define first and second air flow paths across the coil parallel to the coil gradient. In one path the temperature of air flowing across the coil is reduced while the air gives up heat to the refrigerant. The other air flow path heats air passing across the coil. A multiplicity of pressure reducers are provided in the coil to progressively drop the temperature of the refrigerant from one end of the coil to the other. A supplemental coil can be used in conjunction with the second air flow path to heat air further. The supplemental coil may receive hot refrigerant directly from the condenser.
