All-day experimental tests were performed to determine the thermal
performance of two commercial integral storage collectors for solar
domestic hot water systems. These tests were performed under a variety
of ambient conditions and irradiance levels, both with and without
forced circulation and noontime hot water draws. An analytical model
was developed to predict the thermal performance of one of the two
systems tested and predicted performance was compared with experimental
results. Experimental and analytical results indicate that thermal
stratification has a mininal effect on the daily collection efficiency
of integral storage collector, so that a standard test similar to ASHRAE
Standard 93-77 might reasonably be used to obtain the performance characteristics
of the collection element of these systems. The results of
an ASHRAE 93-77 type test might then be used to obtain performance
ratings under ASHRAE Standard 95 procedures using an in-line heat
source. The results of the present investigation may be used to validate
such an ASHRAE 95 test method.
