ABSTRACT:
A dual loop, heat driven, heat pump system including an expansion-compression device with a linearly movable operating mass such as a free piston assembly; a Rankine cycle power loop with a working fluid operatively connected to the expansion-compression device to drive same; a vapor compression heat pump loop with a working fluid operatively connected to the expansion-compression device to be driven thereby; and control means for selectively associating the working fluid of the power loop with the linearly movable mass of the expansion-compression device to cause the power loop working fluid to drive the movable mass linearly and induce linear kinetic energy in the movable mass, and for selectively associating the working fluid of the heat pump loop with the mass while the linear kinetic energy is stored therein to cause at least a portion of the kinetic energy of the mass to be transferred to the heat pump loop working fluid as compression work. The disclosure also comprehends the method of operation of the system.
