The A-Frame Industries site is located in Kaneohe, Hawaii, and is a single family residence containing a solar energy system designed to provide domestic hot water heating. It is an open system, utilizing city water pressure to overcome the pressure head of the DHW tank and solar collector subsystem. The system uses city water as the common heat transfer medium, and contains no energy storage tank or DHW tank heat exchanger loop. Therefore, the total operating energy is in the energy collection and storage subsystem (ECSS). The collector consists of an array of four flat-plate collectors with a gross area of 76.6 square feet. The collectors face 10 degrees east of south at an angle of 21 degrees from the horizontal. The heat transfer medium is potable water, which is stored in a 120 gallon water heater storage tank and supplied, on demand, to the domestic hot water supply. Auxiliary heat is supplied by a 4 kilowatt electrical heating element. The collector loop pump is activated when the collector temperature exceeds the storage temperature by 5/sup 0/F. The pump is stopped when this temperature difference becomes less than 2/sup 0/F. The hot water service design temperature is 140/sup 0/F. No maximum temperature control or freeze protection is provided. The house has been fully instrumented for performance evaluation of the solar system since February 1978 and the compiled data are integrated into the National Solar Data Network. Original cost estimates for provisioning and installation of the solar system are given; the final solar system and instrumentation cost are not included. (WHK)
