Solar energy system performance evaluation: seasonal report for Decade 80 House, Tuscon, Arizona
The solar energy system was designed to provide domestic hot water and a 3200 square foot floor area with space heating and space cooling to a one-story, single family residence located in Tuscon, Arizona. The solar energy system consists of a 1923 square foot flat plate collector array subsystem, a 3000 gallon tank storage subsystem, pumps, controls and heat transfer medium lines. A propylene glycol (30 percent) and water (70 percent) solution is used as the energy collection and heat transfer medium. The collector-to-storage loop also contains a heat exchanger used to heat a swimming pool. The domestic hot water subsystem consists of a 66 gallon conventional electric storage tank to which solar energy is supplied by a pump circulating water through a heat exchanger immersed in the 3000 gallon storage tank. Auxiliary energy for heating is provided by a gas-fired 150,000 Btu/hour boiler. Space cooling is provided by two absorption cycle water chillers operating in parallel. The solar energy system has four modes of operation. The analysis used is based on instrumented system data monitored and collected for at least one full season of operation. The objective of the analysis is to report the long-term field performance of the installed system.
