Household-based heat metering method and household-based heat metering device

Abstract

The invention relates to a household-based heat metering method and a household-based heat metering device, and belongs to the field of heating ventilation air conditioning technologies. The technical scheme is as follows: summation of heat used by all users in a building is measured by a heat meter of the building, and the total heating load is apportioned by each user according to an on-off time area method. In a heat apportionment process, the turn-on time of an on-off control valve of a user heating system and a user heating area are taken as the apportionment basis, apportionment factors are introduced and are used for carrying out real-time correction on the apportionment heat. By introducing the apportionment factors, key parameters, which are involved with direct measurement of the heat such as the water flow, the inlet temperature and the outlet temperature of the heating system, are integrated into integrating of the apportionment factors, i.e. the accuracy of the apportionment measurement is corrected in a real-time manner by the direct measurement method, so that the reasonability and the accuracy of the household-based heat metering, and the adaptability under the complicated work conditions are further improved.

Description

technical field [0001] The invention relates to a household heat metering method and device, in particular to a household heat metering method and device for central heating systems, and belongs to the technical field of heating, ventilation and air conditioning. Background technique [0002] With the continuous improvement of the country's requirements for building energy conservation and the continuous improvement of the heating charging system, heat metering and related control technologies for central heating systems have been developed and improved to a large extent. With the promulgation and implementation of the "Technical Regulations for Heat Metering" (JGJ173-2009, hereinafter referred to as the Regulations) as an industry standard, various technologies and applications of heat metering in central heating systems have been effectively regulated. [0003] It is pointed out in the regulations that the household heat metering of the central heating system means that th...

Problems solved by technology

[0007] The purpose of the present invention is to provide a household heat metering method and device to solve the problems existing in the existing direct heat metering or heat apportionment metering methods

At the same time, in order to solve the problem that the existing apportionment method cannot truly reflect the actual working conditions of the user's heating radiators, as well as the consistency of the water supply temperature and heat supply flow, resulting in large errors in heat apportionment, unfair heating fee payment, and the lack of enthusiasm for energy saving of users The method and device introduce an apportionment factor in the calculation process of the heat apportionment ratio, and integrate the key parameters involved in the direct measurement of heat, such as the water flow of the heating system, the inlet temperature, and the outlet temperature, into the cumulative calculation of the apportionment factor, namely The accuracy of apportioned metering is corrected in real time by the method of direct metering, which further improves the rationality, accuracy and adaptability of household heat metering under complex working conditions
