Application of Automatic Energy Conservation Technology to Hot Water Supply System

摘要

In order to realize the automatic energy saving control for centralized hot water supplying system, this paper puts forward a frequency conversion adjusting speed automatic supplement water system with frequency converter used as driving unit pump. It can provide constant supplying hot water pressure by timely adjusting supplement water quantity according to the change of water consumption. The hot water temperature control system was designed to maintain the temperature constant through throttle governing steam quantity. Through the practical run, the whole system works steady, which has remarkable energy-saving effect and high automatic degree.
