Thermal conductivity measurement of two microencapsulated phase change slurries

Abstract

This paper presents results of a thermal conductivity test carried out on microencapsulated phase change materials, to be used as a cooling storage and transport medium in a solar-driven air conditioning system. The microencapsulated slurries can be used not only as an energy storage medium but also as an energy transport medium, and this helps the system to be designed as compact as possible. The test has been carried out on two recently developed microencapsulated phase change materials. A convenient measurement system using transient line heat source technique is introduced, and the results of these measurements are presented in this paper.
