Abstract: To provide, in a gamma free-piston Stirling cooler driven by linear motors, a method for detecting a motor operating frequency for consuming minimum electric power and for detecting a different motor operating frequency that delivers maximum thermal cooling power.SOLUTION: The frequencies are detected by varying the operating frequency in small steps while sensing (1) the input to a linear motor 28 to maintain a steady temperature or (2) the thermal cooling power of a Stirling cooler 10. A mode detection routine detects whether the appropriate freezing apparatus operation is in an electric power minimization mode or a thermal cooling power maximization mode, based upon the current thermal conditions in the freezer. When the freezer 12 is sufficiently cold, pistons 18, 20 of the Stirling cooler are driven at the minimum electric power consumption frequency. When the temperature is, or is likely to become, too high, the pistons of the Stirling cooler are driven at the frequency exhibiting the maximum thermal cooling power.SELECTED DRAWING: Figure 1
