摘要

Ice storage system has ever been used in heating, ventilation and air conditioning (HVAC) systemrnwidely. But the coefficient of performance (COP) of chiller during charging mode is much lowerrnbecause the charging temperature of ice storage is lower. Microencapsulated phase change materialrnslurry (MPCS) has more advantages than ice, when used as energy storage medium in HVAC systemrnof buildings. A general review on application of MPCS for thermal energy storage in HVACrnsystem is carried out first in this paper. Then exergy analyses for 4 kinds of HVAC systems withrnMPCs and ice for thermal energy storage have been compared. An office room is the research objectrnand calculation is based on 1kW cooling load. The results show that the low temperature airrnsupply system has the highest exergy efficiency. And for the conventional air supply systems, thernhigher efficiency is with higher secondary refrigerant temperature.
