Review on active building energy conservation using phase change materials

Abstract

With a increasing application of phase change energy storage technology in the fields of building energy conservation, refrigeration, and air conditioning, the shortcomings of traditional phase change materials (PCMs) have become important, which seriously restricts the development of phase change cold storage technology. Therefore, the new phase change materials have become a research focus in the field of phase change energy storage. The classification and characteristics of phase change materials are briefly described in the paper. In addition, the active building energy-saving are reviewed.
