PCT No. PCT/US82/00648 Sec. 371 Date Jul. 28, 1982 Sec. 102(e) Date Jul. 28, 1982 PCT Filed May 14, 1982 PCT Pub. No. WO82/04098 PCT Pub. Date Nov. 25, 1982.New thermodynamic working fluids with primary application to Stirling-cycle, reciprocating, thermal machines are disclosed which possess a greater dynamic heat transfer coefficient than either hydrogen or helium and which are both chemically inert and easily liquefied. A novel power level control subsystem based on the thermophysical properties of these fluids is disclosed for use in conjunction with Stirling-cycle machines; this new approach greatly simplifies procedures for changing the mean system working pressure, and thereby the instantaneous power level in such machines, during their operation.
