Abstract:
A heat pump system comprising:an hydristor comprising a first compressor half, a second expander half, a first inlet, a second inlet, a first outlet, and a second outlet wherein said first inlet and said first outlet fluidly communicate with said first compressor half and said second inlet and said second outlet fluidly communicate with said second expander half; a closed compressible fluid loop integral with and in fluid communication with said hydristor, said closed compressible fluid loop containing a first closed half loop and a second closed half loop, said first closed half loop in fluid communication with said first inlet and said second outlet, and, said second closed half loop in fluid communication with said first outlet and said second inlet; a compressible fluid contained within said closed compressible fluid loop; a first heat exchanger integral to and in fluid communication with said first closed half loop wherein said first heat exchanger provides heat to said compressible fluid; a second heat exchanger fluidly communicating with and connected in line to said second closed half loop wherein said second heat exchanger transfers or draws heat from said compressible fluid; and a Stirling engine thermodynamically communicating with said second heat exchanger and accepting heat therefrom, wherein during operation of said heat pump system, the compressible fluid passes through said first inlet and is compressed and then exits said first outlet into the second closed half loop, then through the second heat exchanger wherein heat is transferred to said Stirling engine, then into the second closed half loop, then into the second inlet and is expanded, then exits the second outlet, then into the first closed half loop, then into the first heat exchanger wherein heat is transferred to the compressible fluid, then into the first closed loop, thereby completing one pump cycle.
