Direct-heat exchange water evaporator for vapour absorption cycle refrigerators.

Author(s) : EAMES I. W., WU S., SABIR H.

Summary

Vapour absorption cycle refrigerators, powered by low grade heat, potentially offer an environmentally friendly way to cool buildings by using water as their refrigerant. The commercial application of absorption machines for building cooling is resisted primary due to their high capital cost and also their relatively low efficiency when single-effect systems are used. The paper outlines the rationale behind the current absorption cycle research programme and goes on to describe and evaluate the results of a preliminary proof-of-concept experimental investigation into a novel direct air-cooling low pressure water evaporator that potentially offers a way of both reducing the capital cost and increasing the thermal efficiency, of absorption cycle machines.
