A thermal storage medium of microsized capsules of a phase change material in a fluid offers the advantages of high heat capacity per unit volume and high rate of heat transfer to the phase change material. Several samples of Sunoco's P116 wax were encapsulated in particle size of 500 to 1000 ..mu... These samples were subjected to an accelerated simulated solar system environment of temperature cycling through the melting temperature of the wax. The wall durability under the stresses due to the volume change of the wax as it changes phase were evaluated and a capsule identified for additional application studies. A packed bed approach to utilizing the capsules in a solar heating and cooling system is being evaluated. A laboratory scale packed bed test assembly was designed and constructed for the experimental evaluation. The packed bed design will be enlarged for full scale tests on a mobile home solar heating and cooling system.
