Solar Water Heating System

This paper describes the application forms of building integrated with solar energy. We explain a solar water heating system; its solar collectors and water storage tanks are placed together. We discuss another solar water heating system, its solar collectors are placed together but its water storage tanks are placed in every resident's home. This paper also introduces the wall-hung SWH and the application of solar refrigeration and solar heating. At last we analyze the problems of the development of solar water heater integrated with modern architecture.

Solar Water Heating System

The comparative performance of a cylindrical solar water heating system with and without reflective surface is presented. The major components of the water heater are a transparent cylindrical PVC material acting as the glazing and a copper tube painted black for improved solar energy absorption. One of the systems has it’s under segment, about 45°, lined with an aluminium foil to act as a reflective surface. The two systems were tested under the meteorological condition of the Federal University of Technology, Owerri, Nigeria. Results obtained reveal a maximum exit water temperature from the solar water heater of 68 and 50°C for the reflective and non reflective surface conditions, respectively. The maximum efficiencies were determined as 70% and 40%, respectively for the reflective and non reflective surface conditions while the Hottel-Whillier-Bliss characterization showed that addition of the reflective surface improved the solar water heater’s ability to absorb energy by about 100% and reduced the rate at which it loses by up to 25%. Thus the system with a reflective surface has better capability of converting solar energy to heat for hot water generation.
