냉난방 잠열재가 혼합된 축열조의 냉방 성능 평가 Ⅱ = An estimation of the cooling performance on the thermal storage tank using combined cooling and heating PCM Ⅱ

다국어 초록 (Multilingual Abstract)

The latent heat thermal storage system has been widely adopted to air conditioning for cooling and heating due to the high thermal storage density. However, most type of its application were designed to deal with only either the cooling or heating load. To overcome this drawback, this study considers the thermal storage tank with combined cooling and heating PCM for both operation. Five ratio, from 100% cooling PCM to 100% heating PCM with reducing 25% of cooling PCM, were investigated to estimate the cooling performance. The cooling mode is divided into the charging and discharging process. The performance of each process is evaluated by using the definition of thermal storage density, which is the ratio of storage energy versus tank volume. The maximum thermal storage density was found about 35kwh/m³ and 18.5kwh/m³ at discharging and charging process respectively, whereas the minimum values were approximately 14.5kwh/m³ and 9.5kwh/m³ at each process.
