Evaluation of Chiller On-Off Control of Partial Ice Storage System for Energy Saving in Cooling Operation

부분축열식 빙축열시스템의 냉방에너지소비 절약을 위한 냉동기 On-Off 제어기법의 평가

This paper describes an operation strategy of ice storage systems for energy saving during building cooling. In this study, chiller is assumed not having function of part load control. Thus, it is needed to adopt on-off control with the objective function of summed energy consumption for minimum energy consumption. A conventional control strategy compared with the chiller-on-off control is chiller-priority control. in this control chiller operates as its full capacity and ice storage meets the rest of the cooling load.
