Abstract

The invention relates to a temperature allocation method, in particular to a temperature allocation method for the combined heat metering of multiple buildings. The method of the invention solves the problem of high system manufacturing cost due to the fact that the number of heat meters for calculating total heat by the current metering allocation system based on a temperature method is relatively large, and the problem of the uneven heat allocation of a plurality of heat supplying systems based on the temperature method existing in the current metering allocation system based on the temperature method. The method of the invention comprises the steps that: Step 1. Buildings in a residential quarter are classified into certain areas according to a convenient heat supplying manner; a master combined heat metering gauge of multiple residential buildings is arranged collectively in the residential buildings of the same area and serves as a trade clearing gauge; a plurality of temperature sensors are arranged in each family; by utilizing average indoor temperature measured by each family, and heat allocation of each family is carried out; and Step 2. Heat metering allocated to each user is calculated. The use of the invention reduces the number of heat meters for calculating total heat by the metering allocation system based on the temperature method, thereby reducing system manufacturing cost and causing the heat allocation based on the temperature method of a plurality of heat supplying systems to be more even.

Description

The temperature allocation method of multi-building combining for heat measuring

Technical field

The present invention relates to a kind of temperature allocation method.

Background technology

Temperature method metering shares that every building need be provided with a heat summary table in the system, thereby the heat summary table expense that makes each household bear is higher.With one 48 family building is example, if summary table adopts ultrasonic calorimeter, with 1.6 ten thousand yuan of calculating, each household will be born 333 yuan summary table expense, this will cause developer's building cost to increase, thereby influence applying of the hot measurement technology of heating, influence implementing in full of building energy-saving work.Skyscraper generally need be divided into heating system several region for solving the excessive or imbalance of static pressure, and each district is provided with heat measuring system separately, and each district is provided with a heat summary table, and each hot user shares according to the heat summary table in this district.Can cause the different user of contiguous floors thus, area is identical, room temperature is identical, and the heat of sharing is but different fully.This is a serious unreasonable problem, has run counter to the principle that hot metering heating power is shared.

Summary of the invention

The objective of the invention is for solving the more problem that causes its system cost to increase of calorimeter quantity that existing temperature method measures the metering total amount of heat of sharing system, and the metering of existing temperature method shares the problems that there is the temperature method heat distribution inequality of many cover heating systems in system, and then a kind of temperature allocation method of multi-building combining for heat measuring is provided.

The present invention solves the problems of the technologies described above the technical scheme of taking to be:

The temperature allocation method of multi-building combining for heat measuring of the present invention is realized according to following steps:

Step 1, the building in the residential quarter is carried out subregion according to heating form easily, many residential architectures in the same district is concentrated many residential architectures are set unite metering heat summary table, and with it as the trade settlement table; The plurality of temperature sensor is set in the each household, utilizes the indoor temperature medial temperature of each household metering, carry out sharing of each household heat;

Step 2, calculate the heat that each user shares metering:

1), the heating load in every building:

Every solitary building heating load is an each household heating load sum, for a definite buildings, and the space-heating load data per unit building volume q of buildings _Vz(W/m ³. ℃) be constant, the residing outdoor conditions of buildings is identical, and the heat that buildings is supplied with in time τ and the pass of indoor temperature are:

$Q_z=\underset{i=1}{\overset{m}{\mathrm{\Σ}}}{Q}_i=\underset{i=1}{\overset{m}{\mathrm{\Σ}}}{q}_{\mathrm{vz}}{V}_i(t_{\mathrm{ni}}-t_w)\mathrm{\τ}---\left(1\right)$

Q _i＝q _vzV _i(t _ni-t _w)τ＝q _vzA _iH _i(t _ni-t _w)τ(2)

$Q=\underset{z=1}{\overset{y}{\mathrm{\Σ}}}{Q}_z---\left(4\right)$

In the formula: Q---the gross heat input in many buildings, W;

Total building number in y---many buildings;

3), the heat sharing coefficient in many buildings:

The heating load of each household can be expressed as with the ratio of the gross heat input in many buildings:

$\frac{Q_i}{Q}=\frac{q_{\mathrm{vz}}{V}_i(t_{\mathrm{ni}}-t_w)}{\underset{z=1}{\overset{y}{\mathrm{\Σ}}}{q}_{\mathrm{vz}}\underset{i=1}{\overset{m}{\mathrm{\Σ}}}{V}_i(t_{\mathrm{ni}}-t_w)}---\left(5\right)$

Heating load with each household is expressed as thus:

Q _i＝QKV _i(t _m-t _w)(6)

$K=\frac{q_{\mathrm{vz}}}{\underset{z=1}{\overset{y}{\mathrm{\Σ}}}{q}_{\mathrm{vz}}\underset{i=1}{\overset{m}{\mathrm{\Σ}}}{V}_i(t_{\mathrm{ni}}-t_w)}---\left(7\right)$
