Abstract
A cold storage phase change material was prepared for high temperature cooling application. Its thermophysical properties and charging/discharging performance were investigated. The eutectic point and the influence of mole fraction of different additives on phase change characteristics of the capric-lauric system were tested. The mathematical model of a package ball was built, through which the variation of temperature, storage capacity and storage rate were analyzed. Experiments were conducted to study the charging/discharging performance of the package ball. The results show that the capric-lauric acid combination (mole proportion is 70:30) adding oleic (mole fraction is 0.08) is considered to be well suited to high temperature cooling application with a phase change temperature of 15°C and a latent heat of 114.1 kJ/kg. The charging and discharging processes are stable with a storage capacity of 17.67 kJ for each ball.
