KOREASCHOLAR

The study on ice thermal storage system is to improve total system performance in actual air-conditioning facilities. This paper deals with experimental research to observe the characteristics of heat flow and the effect of ice thermal storage in case of three sizes of ice ball, which are included identification of ice thermal extraction. Diameters of three ice ball was 103mm, 96mm, and 76mm is equivalent to 0.45, 0.50 and 0.55 in porosity respectively. Also inlet geometric parameters are the perforator and distributor. Flow rate of brine were 2LPM, 4LPM and 6LPM and the temperature difference in dynamic parameter are 8℃, 10℃ and 12℃. Flow rate of brine used the liter per minute(LPM) for liquid measurement applications. The effect of brine flow rate on efficiency increased as the temperature difference and porosity increased. An adaption of a long-term storage in case of smaller porosity(ɛ=0.45) was available through experiments of outlet temperature responses.
