Influence Factors during Preparation of Low-Temperature PCMs

Abstract:

For well application in north of China, the optimal properties of phase change materials was screened out by comparing with the same adsorbing material – perlite in Lab conditions. Three main influence factors including adsorption time, experiment temperature and particles of expanded perlite were investigated for all sample of phase change materials. The results showed that capric acid is the optimal one of all samples due to its suitable transformation temperature at 30.1 oC and relative high adsorption proportion of 140% on the vacuum condition at 60 oC in 45 min. All experiments could provide useful data for the building energy saving of Tangshan district.
