Laboratory Test on Total Flow Control for Ice Slurry System with Inverter Fed Motor Pump

인버터구동 모터펌프를 이용한 아이스 슬러리형 빙축열시스템 전유량제어 운전시험

This paper describes total flow control of an ice slurry system for pump energy saving. Similar turbo machinery has a characteristic that input power ratio is proportional to the three time of revolution speed ratio. To reduce the energy cost of brine pump in ice slurry storage systems, inverter is adapted instead of 3-way valve to control the speed of brine pump motor. One type of cooling load profile was used as driving load of the system, generated by a boiler and warm water storage tank. As results of the laboratory test, energy consumption and cost of the pump were reduced by 11.4%.
