Indirect Evaporative Cooling Using Plate Type Heat Exchangers 采用板式换热器的间接蒸发冷却
电力公司越来越强调按需收费率,这促使工程师们为建筑物寻找冷却系统,这将减少建筑物在夏季冷负荷高峰期间的总电力需求。科罗拉多州丹佛市一栋24000平方英尺的办公楼展示了如何在干旱气候下通过使用间接直接蒸发冷却来实现这一点。讨论了可变风量的使用,并分析了其回报。讨论了板式换热器在间接蒸发冷却中的应用。详细讨论了金属冷却塔侧蒸发的传热方面以及由此产生的干燥侧散热。 性能测试结果显示了有效性和压降与堆芯几何形状、空气和水流量的函数关系。对设计特点,如施工材料、维护要求和化学处理进行了审查。此外,还介绍了各种系统布置和应用,以便更好地了解间接蒸发冷却的潜在应用。引文:研讨会论文,佐治亚州亚特兰大,1984年
The movement by electric utility companies to an increased emphasis on demand charge rates has prompted engineers to seek cooling systems for buildings which will reduce the buildings’ total electric demand profile during peak summer cooling loads. An example of how this can be achieved in arid climates through the use of indirect-direct evaporative cooling is presented for a 24,000 square foot office building in Denver, Colorado. The use of variable air volume with this concept is discussed and paybacks are analyzed.The application of a plate-type air-to-air heat exchanger is discussed as it applies to indirect evaporative cooling. The heat transfer aspects of the evaporation on the metal’s “cooling tower” side and the resultant heat dissipation on its “dry” side are discussed in detail. Results of performance testing are presented showing effectiveness and pressure drop as functions of core geometry and air and water flow rates. Design characteristics such as materials of construction, maintenance requirements, and chemical treatments are reviewed. In addition, various system arrangements and applications are presented to allow a better understanding of the potential applications of indirect evaporative cooling.
