Analysis on Issues of Control and Operation Regulation of the Variable Flow in Heat Metering System

摘要

Poor thermal comfort of indoor and low efficiency of heating system can always be found in the buildings with large energy consumption.This paper adopted a comparison method to carry on the energy consumption analysis of several control and operation regulation modes of heat metering heating system.A demonstration project in Tianjin was selected as an example to calculate the energy consumption of circulating water pumps of the secondary pipe network in different combinations of control and regulation,and carries on the comparative analysis.It is concluded that circulating water pumps will be the lowest energy consumption under the remote constant pressure control.And it points out the major problems existing in current,which is beneficial for scholars' further study on heat metering system.
