Heat pump system

A heat pump system comprising, compressor means for circulating a relatively high pressure gas working fluid, a high pressure gas working fluid line interconnecting a high pressure chamber of said compressor means and elements of a vapor compression cycle system, a low pressure gas working fluid line interconnecting said elements of a vapor compression cycle system and said high pressure chamber of said compressor means, compressor piston means in said compressor means for converting relatively low pressure gas working fluid to relatively high pressure gas working fluid in said high pressure chamber to one side of said compressor piston, a low pressure gas working fluid branch line connecting said low pressure gas working fluid line and a low pressure chamber in said compressor means to the other side of said compressor piston from said high pressure chamber, and power means operating on said compressor piston means in addition to the relatively low pressure gas working fluid from said low pressure working fluid branch line for pressurizing the relatively low pressure gas fluid in said high pressure chamber, said power means operating on said compressor piston means employs intermittently pressurized hydraulic fluid.

A heat pump system comprising, power section means having generator means for converting a first working fluid from a liquid to relatively high pressure gas, power unit means providing energy by the conversion of the relatively high pressure gas to relatively low pressure gas to power drive piston means for intermittently delivering a power stroke, power section condenser means converting the first working fluid from the relatively low pressure gas to the liquid, compressor section means intermittently driven by said drive piston means, said compressor section means having a compressor converting relatively low pressure gas second working fluid to relatively high pressure gas second working fluid for circulating the second working fluid through compressor section condenser means and compressor section evaporator means to selectively effect heating and cooling operations, said compressor having compressor piston means interconnected with said drive piston means by connecting rod means.
