Thermal performance testing of flat-plate collectors. View in Source Cite this paper. Test Methods for Solar Collectors — Part 1: The ASHRAE 93 standard requires an experimental determination of the steady-state collector efficiency under prescribed environmental conditions for a range of collector fluid temperatures. The ASHRAE 93 testing procedure is further complicated by the fact ashare the prescribed weather conditions do not often occur in some locations, which prolongs the time required to conduct the performance tests for a given collector.
The EN collector test procedure provides an alternative transient test method that can be conducted over a larger range of environmental conditions. This paper compares the results obtained by applying the EN standard with results obtained from the ASHRAE 93 steady-state tests for a well-designed aahrae selective surface flat-plate collector.
The incident angle modifier coefficient determined in the ASHRAE method, which uses a separate test for this purpose, was found to be more accurate than that determined in the transient method according to the EN standard, which obtains this value and all other collector parameters in the same step. This transient method, however, uses a refined collector model that includes specific terms for the wind speed dependence and the collector thermal capacitance, which are absent in the ASHRAE model.
The long-term collector thermal performance as a part of a water heating system was simulated using the efficiency curves derived from each of the test methods.
