Analysis Of Heating System Regulation Mode

The operation regulation of heating systems has an essential effect on the energy consumption of heating pipe network system,in order to ensure the quality of the end user heating,reducing heating energy consumption to improve transmission efficiency is an urgent problem in the heating system.As a result,the appropriate mode of operation adjustment of the heating system and the rational allocation of water circulating pump in heating system,energy-saving effect will be very considerable.Firstly,This article introducing the general situation of operational regulation mode of heating system both at home and abroad,analysing the mainly using the way of heating regulation of domestic current,variable flow control is the main regulating mode.The phase variable flow regulation and quality regulation of pumps is the main way to reduce heating energy consumption,according to the analysis of these two types of regulation,through the elaboration phase change theory knowledge flow adjustment,change the traditional phase change interval flow way,step by heating the minimum consumption as the target area of Beijing phase change energy flow regulation optimization analysis,reasonable interval flow division of the region has received,and has been a qualitative change in flow regulation and three stage two stage mass regulating energy efficiency is higher by calculation.The variable frequency pump control and valve control and adjustment of cutting impeller are compared,highlighting the advantages of variable frequency pump energy-saving regulation,"in any case,one-sided understanding of the efficient operation as long as the use of frequency control technology can realize the heating system and the regulation of" theoretical analysis,put forward the importance of accurate calculation of hydraulic,at the same time the variable frequency pump efficiency,similar operating point analysis of efficiency curve theory,get the lowest speed,range and operation of variable frequency pump operation,the further introduction of reasonable method of selection of variable frequency pump.Finally,The variable frequency pump in 2015-2016 campus of a certain gas boiler room regulation living investigation and analysis,the actual energy consumption by adjusting the variable frequency pump,combined with the campus heating period outdoor temperature,boiler room equipment and other internal survey data,using TRNSYS simulation software on the stage of variable flow regulation and frequency regulation of qualitative simulation,geting two types of regulation of energy consumption,in this project,phase variable flow quality adjustment play energy-saving advantages of the quality and the quantity of intermodulation,compared to its electricity consumption and gas consumption is reduced and the variable frequency pump control mode.
