The compression/absorption cycle: influence of some major parameters on COP and a comparison with the compression cycle.

Author(s) : HULTÉN M., BERNTSSON T.

Type of article: Article, IJR article

Summary

The article concerns two main studies: a parameter study and a comparison. In the parameter study, the compression-absorption heat pump is focused upon. Its COP sensitivity to changes in the absorber and desorber falling-film tube length, heat exchanger area distribution, and concentration change of the solution in the absorber is studied. The relative distribution between the desorber and absorber is found to have little impact on COP. The area distributed to the solution heat exchanger and the concentration change in the absorber is found to have a large impact on COP when examined separately, but when they are studied together, and with optimized concentration change for each area distribution, the total impact is low. It is shown that the falling-film tubes should be designed to be as long as possible in order to increase the COP.
