摘要：
Isothermalizers placed in the hot and cold spaces of a Stirling engine eliminate the need for a separate gas heater and cooler. For the same displacement, power output is increased and internal flow losses are decreased. Models of isothermalized engines used for pumping water and pumping heat with a liquid column acting as a power piston are described and explained. Comparison of the double Stirling heat engine-heat pump with current and near future heat pumps shows that fuel consumption can be reduced by a factor of 2 and possibly 3. Simplified and rigorous Stirling engine computational procedures are described and compared using a sample case. The kinds of isothermalizers are discussed. Progress in the experimental evaluation of one type of isothermalizer is given.
