摘要
在阐述变频技术节能原理的基础上,结合北京某商贸大厦中央空调系统变频节能改造的实践,进行了效益分析。改造实践证明,对中央空调系统进行冷(热)水循环水泵及冷却水循环水泵变频改造效益明显,改造投资可以在1年左右收回,具有投资前景。
Based on the energy principle of variable frequency technology,analysized of the central air conditioning system with frequency conversion of one commercial building in Beijing.Reforming pract proved the modification benefit was very significant,and the investment could be recovered in a year or so,with broad investment prospects.
