Storage and Exchange Thermal Characteristic Analysis of Phase Change Wallboard Room with Different Condition

摘要：

The application of phase change energy storage have become international study hotpots in the field of building energy saving and HVAC.On the base of analyzing the phase change material (PCM) thermal characteristic systematically and roundly,the paper utilizes testing methods such as differential scanning calorimeter (DSC) etc to select the low melting mixture of capric and lauric acid as PCM of phase change wallboard (PCW).Establish the PCW room,and make contrast analysis of the storage and exchange thermal characteristic of PCW room and ordinary wall room under different conditions.The study shows that the fluctuation of indoor air temperature in PCW room was smaller than that in ordinary room obviously; in the winter condition,PCW room utilized valley period electricity to storage energy in the night,while released at peak period electricity in daytime,which could divert 40% of peak load; in the summer condition,PCW room could reduce cooling 25% than the peak load of ordinary wall room.
