New thermodynamic working fluids with primary application to Stirling-cycle, reciprocating, thermal machines which possess a greater dynamic heat transfer coefficient than either hydrogen or helium and which are both chemically inert and easily liquified. A novel power level control subsystem (Figure 4) based on the thermodynamic 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. |
