地板采暖系统用复合相变砂浆填充材料研究

On the Application of Composite Phase Change Material in the Floor Radiation Heating

阐述了相变砂浆作为填充层材料在地板采暖中应用的意义,采用溶胶-凝胶法制备了以二氧化硅为载体的复合有机相变颗粒材料,配制了相变石膏砂浆.利用地板采暖试验间进行了相变砂浆和普通砂浆的地板采暖试验,以验证相变砂浆地板采暖系统的蓄放热性能,并对地板表面和室内的温度影响进行了试验分析.通过试验验证了新型相变砂浆作为填充层材料应用到地板采暖是切实可行的,在较好改善室内温度环境的同时降低了地板采暖系统的荷载和厚度.

The application of phase change material（PCM） in floor radiation heating system was studied.The composite granule PCM were prepared by sol-gel method and the PCM gypsum mortar was prepared by using the composite granule PCM.Based on the floor heating experiment platform,floor heating experiments was performed by using PCM mortar and common mortar separately to obtain the characteristic of charging and discharging latent heat energy of the containing PCM floor and to analyze the indoor temperature distribution.The results showed that PCM mortar as filled materials in floor heating system will improve indoor temperature environment and lower the thickness and load of floor heating system.
