A CLOSED CYCLE HEAT TRANSFER DEVICE AND METHOD

A closed cycle heat transfer device comprising a boiler (10) and a conden ser (13), the condenser being used to recover useful heat by latent heat eva poration. A circuit defined by the boiler (10), condenser (13) and ducts (12 , 15) is to be liquid-filled at a pressure just above atmospheric pressu...

Zusammenfassung:A closed cycle heat transfer device comprising a boiler (10) and a conden ser (13), the condenser being used to recover useful heat by latent heat eva poration. A circuit defined by the boiler (10), condenser (13) and ducts (12 , 15) is to be liquid-filled at a pressure just above atmospheric pressure. An expansion device (16) maintains the working pressure in the circuit but w ill receive excess condensate in a liquid phase to compensate for expansion of the working fluid vapour which passes from the boiler (10) to the condens er (13). The expansion chamber contains a movable or flexible member which, when working liquid is received in the chamber, is displaced to compress a g as in the chamber.
