计量供热系统热网的自动控制

The Automatic Control of Heat-supply Network in Heat-metering System

计量供热采暖系统是通过对流量的调节实现对室温的控制,从而达到节能。在对流量调节中系统流量的变化可能使得某些用户的流量达不到要求,无法实现室温控制。本文针对这个问题采用定压力控制和定压差控制两种方法对热网进行了自动控制设计,以满足用户所需资用压头,即保证任何时候都有足够流量,以便调节。

In the heat-metering system,for saving energy, consumers regulate the flux in the heating-supply network. When consumers regulate the flux ,may make some other consumers＇ flux in the heating-supply network change and can＇t meet the consumer＇s request for heating, leading to the temperature in the house can＇t be controlled.In this thiese ,the problem is solved by taking automatic control,one is taking static pressure control,this method makes the pressure of supply water keep a certain pressure, and the other one is taking static differential pressure control,this one makes the consumers＇ pressure of supply water and back water keep a fixed number. All the control methods is to provide a available pressure to the consumers,namely is to provide enough flux .so as to regulate heating.
