空调系统变冷水温度调节的节能分析
Energy efficiency analysis of variable chilled water temperature adjustment in air conditioning systems
摘要：
根据空调系统大多数时间在部分负荷下运行的特点，提出在部分负荷时提高冷水温度的调节方案，通过实例计算分析，表明舒适性空调系统采用这种调节可满足要求并且经济效益显著。当负荷率为60%时，采用13.6 ℃冷水，比采用设计工况的7 ℃冷水节能13.3%。

Abstract：
Based on the characteristic that air conditioning systems operate under partial load for most of time, puts forward an adjustment scheme, raising chilled water temperature when operate under partial load. Calculation and analysis results of an example shows that the comfort requirement could be met and the economic benefit is remarkable for comfort air conditioning systems. When the load rate is 60%, adopting chilled water of 13.6 ℃ can save 13.3% of energy compared with adopting that of 7 ℃ required by design.
