축열조를 이용한 냉매과냉각시스템의 전력수요관리 효과에 대한 연구

This study was experimentally performed to find the effects of refrigerant subcooled in the refrigeration system and to aim the efficient use of energy. A refrigerant-subcooling refrigeration system consisted of a typical single vapor-compression refrigeration cycle, a subcooler, and an ice storage tank. The degree of subcooling at the exit of the condenser can be increased by the heat exchange between the subcooler and the ice storage tank. The cold heat in the ice storage tank was stored by using the refrigeration cycle during night time and then used to absorb the heat from the subcooler during daytime. The cooling capacity & COP of the present system were higher than that of the conventional system due to the increase in the degree of subcooling. Generally, the refrigerant-subcooling system showed superior performance to the conventional refrigeration system and this system also contribute load leveling.
