Patent ID: 8522552

Claim:
A heat and power generating system comprising; a thermodynamic external heat source loop having an external heat source of approximately 150° F. or less and a first working fluid in heat exchange relationship with a heat source; a first pump within said heat source loop to circulate said first working fluid and a base heat exchanger; a thermodynamic heat engine loop having a second working fluid, said second working fluid being a refrigerant and a pump in said thermodynamic heat engine loop to circulate said second working fluid and raise its pressure during the thermodynamic cycle and a heat engine in fluid communication with said second working fluid; a thermodynamic heat reclaiming loop having a third working fluid, said third working fluid being a refrigerant, and a compressor in said thermodynamic heat reclaiming loop to circulate said third working fluid and increase the pressure and temperature of the third working fluid within the heat reclaiming loop, said thermodynamic heat reclaiming loop comprising a plurality of subsidiary loops each operating at a different temperature from the others including a first subsidiary loop configured to communicate with said base heat exchanger transferring heat from said first working fluid to said third working fluid; said heat reclaiming loop having a second subsidiary loop including a heat input heat exchanger, said heat input heat exchanger configured to transfer heat from said heat engine loop to said heat reclaiming loop at a different temperature from that of the other said subsidiary loops, said input heat exchanger configured to perform a majority of such heat transfer in said second subsidiary loop when said second working fluid is evaporating and said third working fluid is condensing in simultaneous inverse phase change; said heat reclaiming loop having a third subsidiary loop including a separate heat output heat exchanger, said output heat exchanger configured to transfer heat into said heat engine loop from said heat reclaiming loop, said third subsidiary loop operating at a different temperature from the temperatures of said first and second subsidiary loops, said heat output heat exchanger configured to perform a majority of such heat transfer in said third subsidiary loop when said second working fluid is condensing and said third working fluid is evaporating in simultaneous inverse phase change.
