Abstract
A heat pump, driven by a free piston engine, wherein a refrigeration type of heat transfer unit is used and no externally energized electric motors are required but could be used, if desired. The engine is larger in horsepower than would be required for driving the compressor of the unit only, as it also provides power for driving one or more gas driven or other motors for forcing air through heat exchangers. This arrangement requires substantially less total energy than a unit requiring external electrical energy for operating portions of the heat pumps in that the extra heat in the exhaust from the larger horsepower engine is utilized in a heat exchanger to supply extra heat to the space being heated by the heat pump's primary heat supplier.
