Problems solved by technology

"Its obvious shortcomings have been exposed in the actual implementation: first, the construction technology of the double-pipe scheme is complex, consumes a lot of materials, and occupies a large area; second, each household uses a large number of hot water meters. A filter must be added (the filter is also very easy to block), and the operation reliability is very poor; thirdly, because the contradiction between the heating power consumption and the user's room temperature has not been reasonably resolved, there is currently a problem that although the heat consumption has been measured by household, However, it is an embarrassing situation that it fails to charge each user truthfully according to the measurement results; fourth, it cannot handle the problem of charging users who stop using heat and other problems related to neighbors, and there is a potentially unstable and united society sexual difficulties; etc.

specific Embodiment approach

[0067] 1. Select single-pipe or double-pipe heating (take single-pipe as an example), set parameters: hot water specific heat c, billing start bottom line value T 0 , building scale parameter M, N, heating area parameter S mn , the value of heat power per unit time α, set the maximum absolute value tolerance T of the difference between the temperature sensors in the same room 00 , set the tolerance upper limit δ, δ between any two indoor temperature sensors 0 . After starting the fixed data sampling period Δt timer and the counter J of sampling times, the microprocessor 1 starts from the attached figure 1 The temperature sensors 4, 14, and 5 in the collection collect the indoor and outdoor temperature T of the mnth room at the jth moment jmn1 , T jmnc and T jmn2 , and calculate the difference T jmn =T jmn1 -T jmn2 ; separately from attached figure 1 The supply and return water temperature sensors 6 and 7 in the collection collect the supply water temperature t at the ...

Abstract

A method for centralized heating and individual metering for each room includes such steps as acquiring the temp difference between indoor temp and outdoor temp for each room, the temp difference between supplied hot water and return water for a building, and the flow of supplied water, and calculating the total supplied heat power of a building and the consumed heat power of each room. Its special metering equipment is composed of microprocessor and several temp sensors.

Description

technical field [0001] The invention relates to a metering method and a special metering device for centralized heating in separate rooms. Background technique [0002] Adopting the traditional heat metering and charging device and method is faced with the difficult practical difficulty of single-pipe heating system heat metering and charging. At present, the design of the central heating system in China has been stipulated in the form of legislation (see Ministry of Construction "civil use Building Management Regulations", JGJ26-95, DB13(J)24-2000, etc.): "The central heating system of new residential buildings should (must) adopt a double-pipe system, implement temperature adjustment and household heat metering devices, and implement heat metering Its obvious shortcomings have been exposed in the actual implementation: first, the construction technology of the double-pipe scheme is complicated, consumes a lot of materials, and occupies a large area...
