Wetzel, P. E.

The site is the County Courts Building in Scottsdale, Arizona. Its active solar energy system is designed to supply 100% of the heating and 60% of the cooling load. The system consists of 2723 square feet of concentrating collectors, 5000 gallons of hot water storage, 25.5-ton absorption chiller, and backup electric resistance heating and a 25-ton electric reciprocating vapor-compressor chiller. The system performed far below design expectations due to the extremely poor performance of the collector array. Performance data given include the solar fraction, solar savings ratio, conventional fuel savings, and coefficient of performance. Monthly performance data are tabulated for the solar system and for each subsystem. Also given are monthly solar operating energy, energy savings, and weather conditions for each month. Typical system operation data are graphed and a typical operating sequence is given. Among the appendices are a brief system description, the performance evaluation techniques, typical monthly data, long-term weather data, and a brief discussion of sensor technology. (LEW)
