间接—直接蒸发冷却复合冷水机组的理论分析与应用研究
|
摘要
完善了间接-直接蒸发冷却复合冷水机组制取温度等于环境空气亚湿球温度的冷水的原理及关键影响因素,并通过实验研究得出:高品位干空气能更容易制取温度逼近环境空气露点温度的冷水。提出了不同形式的机组进行分类的依据,对比分析了目前实际工程中应用较广、技术较成熟的几种典型类型的机组各自的特点和适用性。根据不同的条件,正确选用冷水机组的类型,能使系统运行的可靠性、稳定性及整体能效提高,从而使其节能效益最大化。
The principle and key influencing factors of cold water produced by indirect-direct evaporative composite water chiller unit to produce temperature equal to environmental air sub-wet bulb temperature were perfected, and analyzed through the experimental study: high grade dry air energy can make cold water more easily to approach the dew-point temperature of ambient air. The basis for classification of different types of units was put forward, and the characteristics and applicability of several typical types of units which are widely used and mature in the actual engineering are compared and analyzed. According to the different conditions, the correct selection of chillers can improve the reliability, stability and overall energy efficiency of the system, thus maximizing the energy-saving benefits.
