21 High efficiency pool heating system and power unit US959859 1992-10-13 US5313874A 1994-05-24 David Lackstrom
A high efficiency pool heating system (10) includes a power circuit (12) and heat pump circuit (14). Each circuit having a working fluid flowing therein. In the power circuit, a heater (16) vaporizes the working fluid which is periodically delivered and exhausted through a valve section (32) to a driving section (28) of a power unit (26). The driving section drives a driven section (30) which operates as a compressor for the working fluid in the heat pump circuit. Fluid exhausted from the driven section of the power unit is passed to a first portion (48) of a heat exchanger (46) which is in fluid communication with the water of a pool. In the heat exchanger, the working fluid in the power circuit is condensed to a liquid. Thereafter, the liquid is passed through the power circuit back to the heater where it is again vaporized. In the heat pump circuit vaporized working fluid is compressed in the driven end of the power unit and delivered to a second portion (50) of the heat exchanger wherein the working fluid delivers heat to the pool water and is condensed. Thereafter, the liquid in the heat pump circuit is passed through a flow expander (98) and into an evaporator (102) wherein the working fluid absorbs heat from atmosphere and vaporizes. The fluid is then delivered to the driven end of the power unit to complete the heat pump circuit.
22 Add-on refrigerant boiler for electric heat pump US270772 1988-11-14 US4918933A 1990-04-24 David F. Dyer
This invention relates to a method of supplying desired quantities of heat, generated from selected inexpensive fuel burns in the firebox of a boiler, to an electric heat pump's refrigerant, while operating in its heating cycle. This supply of heat can be of sufficient quantities to satisfy the total ouput of the heat pump, minimizing its use of electricity, thereby creating a substantial savings, as the cost of the heat generated by the inexpensive fuel used by the boiler is much less than the cost of electricity.
