A Closed-Cycle Thermally Activated Regenerative Cryogenerator

Abstract

This project is concerned with an example of a device intended to make the most effective use of available energy sources, a principle of increasing importance in present-day circumstances. The machine is intended to provide cooling power to around liquid nitrogen temperatures, especially in unfavorable or remote environments, where direct heat is the available form of energy. Accordingly, the proposed design needs to be rugged, requiring a minimum of maintenance and comprises only two moving parts sealed inside a cylindrical vessel. In this respect it is an improvement on the Vuilleumier refrigerator [¹] on which it is based. This study covers the digital computer simulation of the model, together with some proposals for a practical design.
