Design of cross-flow condensers for ammonia-water absorption heat pumps.

Author(s) : GARIMELLA S., COLEMAN J. W.

Summary

A procedure for the design of air-cooled cross-flow condensers for absorption space-conditioning systems was developed in this study. The refrigerant under consideration is a binary fluid mixture of ammonia and water. The effect of a two-component mixture on tube-side temperature profiles was investigated in detail. Several alternative fin types were considered for the air side. A comparison of the performance of condensers with these different fin types was made. The effect of design variables, such as parallel/serpentine flow arrangements of tubes, fin densities, core depth, and other parameters of heat transfer performance and tube- and air-side pressure drops, was investigated.
