Solar Energy System Performance Evaluation: Hei Wai Wong, Honolulu, Hawaii, November and December 1979 and April Through August 1980

摘要

The Hei Wai Wong site is a four-story apartment building in Honolulu, Hawaii. The building is equipped with three hot water solar energy systems with essentially the same design. One of these systems is instrumented for six apartments and a laundry. The instrumented system consists of an array of flat-plate collectors with an area of 807.4 square feet. The collector and storage subsystem consists of a 1230-gallon storage tank mounted on the roof with the bottom of the tank slightly higher than the top of the collector panels. When the sun heats the water in the collectors above the tank water temperature, a thermosiphon current is induced. When the temperature in storage exceeds the temperature of the water in the collectors, the thermosiphon flow ceases. The solar energy system at Hei Wai Wong supplied 98% of the energy required for hot water for the six apartments and the laundry. (ERA citation 06:010638)
