The Design of Central Heating System Based on A New Kind of Heat Exchanger and The Study of Its Control Strategy

摘要

In order to solve the problem of central heating energy wasting and uneven heating, this paper presents a novel heat ex-changer (jet heat ex-changer) and designs a new central heating system compared with the traditional central heating system based on this new kind of heat ex-changer. This new central heating system can rapidly detect and regulate heat transfer station by using GPRS technology. So that the entire heating network can achieve better operational status and heating quality at the premise of high efficiency and low cost. Finally, the feed-forward control strategy is applied to this new central heating system and achieve better result compared with the traditional PID control strategy.
