Qualitative Experimental research on thermal response of interior finishing material under air-conditioning intermittent running

The response rate of indoor thermal environment is a main factor affecting indoor comfort level greatly under air-conditioning intermittent operation. Interior finishing material can affect inner surface temperature response rate directly as the layer closest to indoor air. According to this situation, in order to explore the thermal response of the different interior finishing material under air-conditioning intermittent running, a experiment is built to analyze the effect of the interior finishing material property on inner surface temperature. Results show that interior finishing property has an significant influence on the thermal response on inner surface temperature. The porous interior finishing material has 20% higher thermal response rate of inner surface temperature than the homogeneous dense materials. Integrating with EPS or rubber sponge in the interior finishing material can improve the thermal response rate of inner surface temperature and the increased response rate can be up to 17.7%~29.6%.
