Summary:
The SOLAR-MEC is the most advanced open-cycle, solid-desiccant heating/cooling system being considered for solar applications. Based on the results of field tests with several residential-size units, begun in early 1975, a 2-year program has been under way. Details of the accomplishments during the first year of the project (FY 1978) are presented which include: (1) development of data necessary to model the dynamic performance of the desiccation process of the SOLAR-MEC system; (2) mathematical description (modeling and computer programs) of the component processes of the system namely, desiccation, heat exchange, and evaporative cooling; (3) development and evaluation of several design improvements to increase seasonal cooling efficiency and capacity (namely, staged regeneration of the desiccant wheel and unbalanced-flow design of the heat exchanger wheel); (4) investigation and redesign of air-seals, wheel support, and drive mechanisms, and of air distribution (including the selection of high efficiency fans) to reduce parasitic power consumption of motor-blower assemblies; (5) investigation of the long-term stability of the rotary heat exchanger wheel performance including the selection of a low-cost alternative matrix; and (6) investigation and liaison activity for the selection of a practical non-asbestos molecular-sieve support matrix for the desiccant.
