Heat pump containing a piston compressor and driven by a piston engine

Patent ·
OSTI ID:6574446
A heat pump contains a piston compressor which is driven by a piston engine. The refrigerant on the low pressure side of the heat pump drives the engine during the compression stroke of the engine. An accumulator chamber for the low pressure refrigerant is provided adjacent the compressor. The volume of the accumulator chamber is so large that the compressor piston, and consequently also the engine piston, is given a speed high enough for producing the required compression in the engine cylinder.
