冷水式精密空调机组节能控制方法研究

Research on energy-saving control method of chilled water cool precise air-conditioning unit

由于冷水式精密空调机组的节能受冷冻水系统是否变频的制约,本文对冷水式精密空调机组节能控制方法进行试验研究,认为采用变风量与冷冻水流量相结合的控制方法可以使该机组更节能,避免传统控制方法完全依赖冷冻水系统是否变频以及流量变化到压差变化的转化所带来的误差控制等弊端。

Due to the restrictions of energy-saving of the chilled water cool precise airconditioning unit by user's chilled-water system variable-frequency or not,experimental research on control method of chilled water cool precise air-conditioning unit is carried out.It is considered that using the control method of variable air volume combined with chilled water flow can make the unit more energy-saving,avoid the shortcoming of traditional control method depending on user's chilled-water system variable-frequency or not,and the error control caused by the conversion from flow changes to differential pressure changes.
