Application of Multivariate Composite Phase Change Materials in Building Exterior Renovation

Abstract

As an effective way to achieve a low consumption in the building energy efficiency field, the Phase Change Material (PCM) and Energy Storage (ES) technology have created a favourable condition for application of solar energy, wind energy and other low-cost clean energies in the heating system, A/C system. This paper probes into the simulation and application of composite PCMs in the exterior building enclosures with the physical model of houses. We therefore reach that the phase transition mortar board can effectively reduce the indoor temperature and stay the temperature fluctuation time when it is used for the outer insulation layer, such that it is sure to superior to the common mortar board.
