Study Of The Cost Allocation Of Household Building In Xi'an

With the innovation of heat supply in our country, the household heat metering of centralized heat supply is becoming more and more popular. But only by a simple measurement of heat charges on a system of fees is fair lose.Then Produced a part of the heating charge from the user's heating area, a part of heating charge from the user's heating measurement。Due to the operating characteristics of the system,the influence of heat transfer between household and intermittent heating should be considered calculating the heat load of house about household heat metering。So it is a focus for the calculation of basic heat fee and measurement heat fee's proportion,and accordance with public consumption of energy in accordance with the measurement of heat amendment. And the problem has a direct effect on heating supply results, investment economics and effective use of energy.The subject used Cost-effective structure,CFD,Theoretical calculations and Building energy simulation of the analysis.The research process of the subject:①Use the cost-effectiveness analysis methods, analyzed on the cost of heating enterprises in Xi'an, determine the basic price and measurement prices, determine the proportion of the basic measurement and costs expenses of thermal fees.②Use FLUENT simulationged on adjacent three-tier heating room in Xi'an, According to the heat transfer between the household of the basic fee and tne measurement heat fee's proportion for reasonable adjustments.③From the theoretical point of view of public consumption in Xi'an heat extraction coefficient, extracted from the public and heat consumption in the hot-sharing among users, consider the construction of the user's position on the measurement of the heat value of different amendments.This paper analyses come to the Xi'an area in the two-parts charges, the method of the proportion on basic measurement fees and total fees,and the amendment method of measuring heat accordance with the public area of heat loss, Guidance on the implementation of reform measures heating charges, with some reference value.
