Abstract
An absorption-cycle heat pump comprises a rotary assembly including a vapor generator (GE,14), a condenser (CO,23), an absorber (AB,22), an evaporator (EV) and a solution heat exchanger (X,16). The vapor generator, the condenser and the absorber each include a wall (14, 23, 22 respectively) across which the volatile component (preferably water) and/or a liquid absorbent therefore are caused to flow under the action of the forces generated during rotation of the assembly. The evaporator comprises a plurality of finned heat exchange tubes 31 into which the volatile component is injected with a radially inwardly-directed component of motion, the tubes being of generally elliptical configuration disposed with their major axes extending generally radially. To maintain the evaporator heat exchange surfaces continuously wetted, excess volatile component is supplied such that a major part of the latter remains unvaporised after flow across the evaporator heat exchange surfaces and is collected in a reservoir (26), which also receives the condensate from the condenser, for re-injection into the evaporator tubes (31).
