摘要
对杭州某办公楼空调冷热源系统进行节能改造,采用电动变频磁悬浮离心式冷水机组,横流式冷却塔及室外型预混燃烧天然气真空热水机组替代原有的风冷螺杆式冷热水机组,同时对输配系统的水泵进行更换并加装变频装置。依据测试结果及实际运行能耗数据,空调冷热源节能改造后节能效果显著。
The cooling and heat source system of air conditioning in an office building in Hangzhou was reformed to save energy.The electric variable frequency magnetic centrifugal chiller,cross-flow cooling tower and outdoor premix-combustion natural gas vacuum hot water unit were used to replace the original air-cooled screw chiller.Meanwhile,the water pump in the transmission and distribution system was replaced and a frequency conversion device was added.According to the test results and the actual energy consumption data,the energy-saving effect of air-conditioning cooling and heating source is remarkable.
