Process and device for measuring the heating energy consumption share of individual users in a centrally heated building

摘要

1. Arrangement for measuring the relative energy consumption of the heating of dwellings in a multiple property comprising, for each dwelling (Li) of the order i of the property : - means (El), (1) for sampling at predetermined instants the instantaneous mean temperature ti of each dwelling (Li) and at least one reference temperature, of at least one point situated outside the property, the said sampling means (Ei) comprising at least one temperature sensor (Ci) conveniently arranged in the dwelling (Li) of the order i, at least one sensor (Cr) for the reference temperature (tr) and means for controlling the sensors permitting periodic reading of the temperature ti, tr displayed by these sensors, - subtraction means (12) adapted to derive the difference between the mean temperature ti of each dwelling (Li) and the reference temperature tr, - means, (1, 2) for integrating over a period equal to the heating season or over an elementary period which is a sub-multiple of the duration of the heating season, the divergence of the said instantaneous temperatures in a manner such as to define over the corresponding periods a mean temperature difference Tid for each dwelling (Li) of the order i, - calculating means (3) allowing the determination over this period of a value Rid of the measure of the relative energy consumption of each dwelling (Li) in accordance with the relation see diagramm : EP0181259,P15,F1 where Tid represents the mean divergence of the temperature of each dwelling (Li) taken with respect to the period determined and equal to, or a sub-multiple of, the heating season, Vi representing the effective habitable volume of each dwelling (Li), - means for calculating the share rho i of the individual heating charges for each of the dwellings (Li) of the order i, the said share rho i being determined proportionally : - with respect to the period of occupation delta i of the dwelling (Li) of the order i over the period D of the heating season, - with respect to the volume Vi of the dwelling (Li) of the order i in relation to the total volume V heated by the overall heating system V = SIGMA i Vi, - with respect to the mean divergence DELTA ti delta between the mean inside temperatures of each dwelling (Li) of the order i and the outside reference during the period of occupation delta i of the dwelling (Li) of the order i to the mean divergence of the temperature DELTA T for the set of dwellings during the heating season or a submultiple of it, the said share rho i being of the form : rho i = D x SIGMA Vi x DELTA T/delta i x Vi x DELTA ti delta
