Research on performance of radiant floor heating system based on heat storage

Abstract

With the development of the economy, improving energy efficiency and saving energy have become important issues that need to be addressed. In terms of building energy efficiency, combining phase change heat storage material with floor radiation heating is an effective way to improve energy utilization efficiency. In this paper, a composite phase change heat storage material used in radiant floor heating was introduced. Based on the selected materials, experiments on floor radiation heating system based on heat storage in different environments during the heating season were conducted. The results showed that thermal conductivity of composite phase change heat storage material increased by a maximum of 97.2%, and the maximum heat release time can be obtained 6 h. By using this radiant floor heating system, a balance between heating comfort and economy has been achieved, so this system will have a good applied foreground.
