Performance Predictions and Test Results of a Free Piston Stirling Engine Driven Heat Pump

Recent progress on a Stirling engine driven hea t pump is described and a modeling technique for predicting engine dynamics is developed. The system described represents a very p romising configuration of engine driven heat pump, because o f the long life characteristics of the free-piston Stirling engin e and the hermetic nature of both the engine and refrigerant work ing fluids. Recent change...

An Investigation on the Effects of Gas Pressure Drop in Heat Exchangers on Dynamics of a Free Piston Stirling Engine

This paper is devoted to study the effects of pressure drop in heat exchangers on the dynamics of a free piston Stirling engine. First, the dynamic equations governing the pistons as well as the gas pressure equations for hot and cold spaces of the engine are extracted. Then, by substituting the obtained pressure equations into the dynamic relationships the final nonlinear dynamic equations gov...

Dynamic Behavior of a Free-Piston Stirling Engine Driven Heat Pump With Magnetic Coupling

A new low-cost design for a free-piston Stirling engi ne driven heat pump is presented. The new approach uses a linear-acting magnetic coupling to transfer engine power across a hermetic shell. Camp l i ance in the coupling affects the performance and stability of the system, especially with regard to matchin g the engine dynamics to the compressor load. This paper first describes test results ...
