Research on active solar processes. Final report

OSTI ID:5472144
The research centers on the development of methods of simulation of solar processes (i.e., TRNSYS) and the use of those methods to study specific processes, prediction of their long-term performance, and their control. An analysis of flat-plate collectors with boiling fluids has resulted in the development of collector (plus condenser) models suitable for use in TRNSYS and for determining collector parameters for use in FCHART. Active system control strategy research has shown that operation of DHW systems at low collector flow rates can lead to significant improvements in system performance if tank stratification is maintained. Effects of time distribution of solar gains on building loads and thus on active system performance have been determined and corrections to FCHART predictions have been worked out. This has led to methods for calculating performance of hybrid systems based on utilizability concepts. During the contract period TRNSYS 12 was released; it includes new components and capabilities. A new FCHART 4.2 will be released in May and will include capability of estimating performance of hybrid systems, no-storage space heating systems, several types of passive systems and swimming pools.
