Main components of the ice storage system are an ice-on-coil storage tank and a screw compressor chiller. With the simulation program, the operation cost has been evaluated from the economics of an ice storage system. It is found that the operation cost of the ice storage system is strongly dependent on the control strategy, i.e., chiller priority or storage priority, but less affected by the arrangement method, i.e., chiller upstream or chiller downstream. In case of the maximum load day, the control strategy with chiller priority and chiller upstream is supposed to obtain the reduction of operation cost. However, it is found that the control strategy with storage priority and chiller downstream is the best economical operation for most summer seasons except the maximum load day. 대한설비공학회 빙축열 냉방시스템의 운전특성 및 비용 분석 The Operation Characteristics and Cost Analysis of an Ice Thermal Storage System Article 2 설비공학 논문집, v.17, no.2, pp.156 - 164 설비공학 논문집 17 2 156 164 kci ART001101878 빙축열시스템 운전방식 운전경비 Ice storage system Operation strategy Operation cost
