Building Heating Measurement Transformation And Research Of Related Issues

The level of energy consumption is very huge in our country at present,especially in the heating supply system. Realizing the measurement technologies inheating supply system is the chief trend of The Times in China,it can promote thebuilding energy efficiency and reduce the environmental pollution. The Chinaministry of construction have given the plan that gradually realize the metric charge inresidential heating supply from2000.Most of the cities in China is gradually theimplementation of the heating measurement technology, widely carried out theheating measurement renovation project, but in its implementation process therereally such as building operations non-standard, design is not reasonable andmeasurement methods improper selection, etc all kinds of problems, leading to thealthough install the measuring equipment, indeed, are not in charge by measurementmethods and other unreasonable phenomena etc.Not only can not reflect theenergy-saving benefit by measurement technologies application in residential heatingsupply system, but also cause a serious loss in investment.Combining with the specific engineering examples, the choice of the ways ofheating measurement, and the ways of transformation of heating station, residentialentrance of heating supply system are gaven from the angles of the technologyeconomy analysis, and some conclusions are drawn for the technical personnelreference; For the particularity of the heating measuring system, this paper applied the“HacNet” fluid distribution analysis software on the initial adjustment in thermalmeasurement system; in combination with the water power banlance regulation andcontrol of some new theory, this paper puts forward the comprehensive adjust andcontrol methods for thermal measuring system, the introducing radiator logarithminstead of average temperature difference in the hydraulic balance adjustment basicformula, and calculating with a method of computer the iteration; The mostunfavorable loop pressure control theory is refered to guarantee every user withsufficient differential pressure under the premise energy-saving.For charge problems in thermal measure system, puts forward to points usingratio between per unit area of actual heat consumption and user room unit area design heat consumption as coefficient, make users’ heat consumption share the public partsof heat consumption, and effectively keep down the heating wastes for the user’swindow exothermic behavior. And application Visual Basic language and ActiveX(ADO Data) database Access interface through the Microsoft Jet database enginerealized the secondary charge model, management and storage function for the users’charging information,and application of SQL (structured query language) has realizedto Acess2007Data access functions. If GPRS long-distance meter reading system isapplied, the software can also further through the Remote Data control of the Remotedatabase links, realize computerization and automation for the the managementprocess of heating measurement and make the follow-up and complicated meteringand accounting process in heating measurement to be simply, and can also save a lotof manpower.
