Positive Effect

The building energy conservation has an important role in the energy field. Lightweight materials have been extensively used. By compositing the capric acid (CA) and lauric acid (LA) eutectic and using the expanded perlite (EP) as the matrix, a phase change material (PCM) was prepared and studied in laboratory. The mass fraction of this PCM reached at 60% through direct immersion for 24 hours. Differential scanning calorimeter (DSC) testing results indicated that the melting temperature of the PCM is 18.0°C, and the latent heat is 73.77J/g. From 1000 times cycling and heat-release characteristic test, this PCM was found to be stable well. After 2(wt)% graphite added in, solidification time of the PCM decreased by some 30%, the thermal conductivity improved. Application showed that the PCM has a positive effect on improving indoor environmental temperature.

Low Temperature Phase

Phase change energy storage building material has become a widespread attention for the field of building energy conservation because of its excellent storage properties. The phase change material which is able to adjust the indoor temperature, belongs to the low temperature phase change material. There are lots of kinds of it, and then how to find a suitable phase change material has become a key problem. In this paper, the characteristics of the inorganic material, single organic material, and binary organic material were tested, and the phase change temperature and latent heat of composited phase change material were analysed by differential scanning calorimetry(DSC), which could provide a theoretical basis for the search for the appropriate phase change material.
