Desiccant dehumidifier/cooling system development. Final report, December 1982-May 1985
Under Gas Research Institute (GRI) sponsorship, Exxon Enterprises, Inc. developed and breadboard unit tested a patented desiccant-cooling-system concept that produced significantly higher thermal efficiencies than had previously been achieved. Based on this concept, Dunham-Bush analytically projected ARI thermal coefficients of performance (COPs) of over 1.0 to be achieveable in the breadboard desiccant cooling system. Furthermore, the first cost estimates made by Dunham-Bush for a commercial product projected an approximate 45% premium over the first-cost of a state-of-the-art electric vapor-compression air conditioner in the 5 to 7-1/2 ton size range. The estimated operating costs associated with the desiccant system, although very low, could not offset the large first-cost premium in a reasonable payback period.
