摘　　要：动态冰蓄冷技术在国内首次应用于牛奶加工工艺冷却过程,通过改造原有冷水机组,利用普通水制备的0℃冰浆,针对不同乳品加工冷却过程分别提供1℃的低温冷水和10℃高温冷水。这改变了牛奶行业固有的统一供低温冷水的格局,达到了能源梯级利用,节能减排的目的。系统增设一台170RT双工况螺杆式制冷机,研制相应制冰设备,蓄冰槽体积为98m3。总蓄冷量为1020RT·h,实现转移高峰电量22.29万kWh,年节约电费38.04万元,单位产品吨耗下降9.90元/吨。The technique of dynamic ice storage is firstlyproposed for milk cooling process in China.Reforming the original water-cooled chiller and preparing ordinary water for 0℃ slurry ice provide 1 ℃ cold water and 10℃ warm water for the cooling process of different dairy products.It changes the pattern of the inherently unified low temperature cold water supply.It achieves the goal of energy cascade utilization,energy conservation and emissions reduction.A 170RT ice making equipment with 98 m3 ice storage tank is developed coupled with corresponding main unit.The total cool storage of the ice making equipment is 1020RT·h.This equipment can remove peak electricity by 222,900 kWh,saving 380,400RMB on air conditioning system annually.
