- Abstract
- ASHRAE has recently adopted ASHRAE Standard 95-1981, Methods of Testing to Determine the Thermal Performance of Solar Domestic Water-Heating Systems. The Standard requires the complete system, including auxiliary energy sources, to be assembled in the laboratory and subjected to a daily hot water load and irradiation profile until the daily system performance is repeatable. Data are then collected and analyzed to determine the fraction of the daily energy requirements met by solar energy. The system's solar collector array can be irradiated by a solar simulator or the net thermal energy delivered by an irradiated collector array may be provided by the use of a nonirradiated array in series with a conventional energy source.
