摘要
与中央空调冷冻水泵变频相比,冷却水泵变频问题研究较少,争议也比较多。本文对有关冷却水泵变频节能的文献进行了辨析,认为冷却水泵变频是节能的,应该比冷冻水泵变频具有更大的节能空间。文献所提的计算节能量的方法不准确,不能用于评价项目的可行性。本文论证了一种计算冷却水泵变频节能的方法,可以简单但准确地计算冷却水泵变频的节能量,计算结果可以用于项目的可行性评价。
There were rather less studies on the frequency conversion of cooling water pumps in central air conditioning systems than that of cold water pumps. While, immense controversy is on the subject. This study analyzes the related literatures and concludes frequency conversion of cooling water pumps is energy saving, even more than that of cold water pumps. A new method to calculate the amount of energy saved by frequency conversion of cooling water pumps is put forward. Such methods in literatures are unprecise and not suitable for accessing the feasibility of real projects. The present method is simple, but relatively precise and can be used to access fact projects feasibility.
