Security Analysis of Solar Building in Extreme Weather
Abstract:
In order to prevent the solar heater falling off the roof in extreme weather and spread the solar building technology, this paper gave a feasible inclination and new connection for collectors used in slope roof and ridge in cold district. The reliability of connection was analyzed under snowstorm and fierce wind condition. The results showed that raising the inclination angle of heater 3°higher than local latitude was beneficial to ensure the security of collector and to reduce the energy consumed by buildings. In the event that the whole load has acted on a single expansion in combined load condition, it remain contained 286% safety margin, while safety margin was up to 415% under fierce wind circumstances individually. It is obvious that the connection is quiet suit for installing heaters on the roof without forethought pedestals.
