DYNAMIC MODELING OF WATER- AND AIR-HEATING SOLAR COLLECTORS
Résumé
The development, verification with test data, and comparison of first and higher order dynamic models of flat plate solar collector thermal performance are described. Collector models are nodalized by components such as covers, absorber plate and insulation as well as segmented in the flow direction. Typical water- and air-heating commercial collectors are studied. Few node models, in which the major components are lumped, are recommended to provide adequate dynamic response characteristics. Continued and developing interest in the use of collector dynamic models is expected due to the importance of operation during periods of low and varying solar intensity and the prospect of flow control in solar heating systems.
