A SOLAR WATER SYSTEM ACTING AS THE BUILDING MATERIALS

摘要：

A new type of solar water system in the form of building material is designed, and applied to an office building in Meijiang eco-district located in Tianjin City, China. In this project, 60m2 wall type and 30m2 solar roof collectors are used to supply hot water directly and also to be an evaporator for an auxiliary heat pump with a power of 4.5kW. The energy rejected by the condenser contributes to load requirements through a refrigerant (R22)-to-water heat exchanger immersed in a 3m3 hot water storage tank. Experimental results show that, the daily-averaged collector efficiency ranged from 40 to 50％ and form 60％ to 70％ in winter and summer, respectively.
