基于冰蓄冷中央空调的自动控制研究与设计

Automatic Control Based on Ice Storage Central Air Condition

冰蓄冷空调是利用夜间低谷负荷电力制冰储存在蓄冰装置中,白天融冰将所储存冷量释放出来,这样可减少电网高峰时段用电负荷及空调系统装机容量,它代表着当今中央空调的发展趋势。通过对冰蓄冷中央空调的水温、水压、流量和空气温度、湿度、风量、压力、风阀开度等各种参数进行监控,并且在预测空调负荷的基础上确定冰蓄冷空调系统工作模式,从而改变控制策略,进一步提高冰蓄冷空调的节能水平。

On the basis of monitoring a variety of parameters of ice storage central air-conditioning,such as temperature,pressure,flow,air temperature,humidity,wind value,pressure,valve opening and so on,and predicting the load of air conditioning,and can determine the operating mode of the ice storage air conditioning system.So can change the control strategy to further improve the energy efficiency of ice storage air-conditioning.
