Heat quantity divided gauging method for heating

Abstract

The invention discloses a household metering method of warming heat, which belongs to the heat metering field. The method includes the following steps: A. metering the total heat Q2 of the system; B.determining the proportional coefficient pi of the heat of the metering unit in the total heat of the system to be detected. In the specific method: B-1: the inlet water temperature and the outlet water temperature of each metering unit are collected in the definite time; B-2: a standard enthalpy value table and a density value are used for finding out the enthalpy value and density of water of the corresponding temperature; B-3: calculating the proportional coefficient of the heat of the metering unit in the total heat is calculated according to following formula: pi is equal to (Rho<1i>h<1i>--Rho<2i>h<2i>k) / Sigma(Rho<1i>h<1i>-Rho<2i> h<2i>k); C. the heat of the metering unit is determined according to the following formula: Qi is equal to piQ<2>. The method eliminates the measurement of the proportional relation ki of the flow of each metering unit in the existing metering method, simplifies the measuring procedures, improves the measuring efficiency, and simultaneously prevents the systematic error of the measurement.

Description

technical field The invention relates to a heat metering method, in particular to a household metering method of heating heat. Background technique In the northern region of our country, the issue of heating in winter has always occupied an important position and often becomes the focus of people's attention. The basic situation of my country's urban heating metering and charging is: heating companies and heat users do not have measuring instruments at all, and they still charge for heat settlement according to the traditional backward building area, resulting in no scientific basis for charging. This charging method is neither scientific nor fair Reasonable. At present, with the advancement of heating marketization, the contradiction of heating and heating charges has become increasingly prominent, and there is an urgent need for a household heating metering and billing device suitable for installation in urban residents' homes; therefore, heat meter metering has emerged ...

In this case, if you still measure the flow ratio relationship of sub-users, it will not only increase the difficulty and cost of measurement, artificially reduce the measurement efficiency, but also increase the measurement error that may be caused by different measurement environments; at the same time, increase the measurement Link, may also increase the chance of systematic error
