Experimental Study on Heat Transfer of PCM-filled Window
摘要
Abstract
Two kinds of binary composite phase change materials ( PCMs) were prepared using a melt blending method with myristic acid ( MA) and cetyl alcohol ( HD) as the raw materials. The eutectic temperature and latent heat in phase change were tested using DSC, and they are 35. 5 ℃ and 218. 23 kJ/kg, respectively. After 300 thermal cycles applied during the experiment, the results show that the MA-HD eutectic temperature in phase change undergoes a change of less than 0. 2 ℃. This indicates that the thermal stability of the MA-HD binary composite phase change material is good. A high-low temperature box within a temperature range of 18-58℃ was used to simulate the outdoor temperature during the summer. The temperature response for a PCM-filled window and a hollow window was tested. The ex-perimental results show that the temperatures of the outer and inner surface of PCM-filled window are 5. 9 ℃ and 0. 6 ℃ lower than those of a hollow window, respectively. The surface temperatures of the PCM-filled window remain constant for 100 min, and the effects of the temperature control are good, which shows that the PCM-filled window has a good load transfer capability.关键词
