Application of Phase Change Wallboard to an Energy-Conservation Building in the Cold Area in North China

Abstract

The application of phase change energy storage has become an academic focus in building energy conservation. This paper considers day and night climate conditions and the governmental regulation of price of electricity in testing and analyzing the characteristics of phase change energy storage material with DSC. We selected two kinds of fatty acid as phase change material to make a phase change wallboard, and then carried out a thermal functional analysis of performance of the wallboard. The results indicate that the application of phase change wallboard in the cold northern region, where there are abundant natural resources, combined with the national policy of reducing the cost of electricity and shifting portions of the load from periods of maximum demand, can reduce costs and HVAC energy consumption, and is an effective way of reducing building energy consumption and improving the environment.
