Coal-to-gas and coal-to-electricity heating heat distribution metering device and method

Abstract

The invention relates to a coal-to-gas and coal-to-electricity heating heat distribution metering device and method and relates to the building heating metering field. Through the heating distributionmetering method, heat loss amount of different position users is determined, unified heating device and pipeline refitting is carried out for the whole building, and heat distribution and metering are carried out. The method is advantaged in that not only can heating requirements of users be satisfied, refitting conditions of heating systems of existing building structures are satisfied, but alsosafe and stable heat supply for each user especially for users at the middle part is realized, the comfortable temperature is realized on the condition that cleanness and low consumption are realized, and heating cost is reduced.

Description

technical field [0001] The invention relates to the field of building heating metering, in particular to a method and application of a heat distribution metering device for central heating. Background technique [0002] In order to reduce the smog in winter, the promotion of clean energy heating has been launched successively across the country. Correspondingly, relevant policies for coal-to-gas or coal-to-electricity conversion have been issued. In the prior art, the energy consumption of each household is generally measured by the consumption of natural gas or electric energy. It appears to solve both heat distribution and metering problems. However, it is only applicable to single-family buildings such as villas, and is not applicable to most apartment buildings. Specifically, compared with the multi-layer or high-rise distribution and measurement method, the heat loss required by the ceiling household, the marginal household and the intermediate household under the sa...

Problems solved by technology

However, it is only applicable to single-family buildings of the villa type, and is not applicable to most apartment buildings

Specifically, compared to the multi-layer or high-rise distribution metering method, the heat loss required to achieve the same room temperature is different for the top house, the edge house, and the middle house, and it is difficult to measure accurately with the existing technology

Therefore, the existing technology often appears: ① uneven distribution of energy among different households, insufficient electricity / gas supply for neighboring households or top households, and excessive or unstable voltage or air pressure for intermediate households; Furnaces have brought greater air pollution and energy loss, making it difficult to control the energy consumption of each household; ③The burden of original natural gas / circuit pipeline heating modification is too heavy, and the safety factor is low; ④The cost of individual wiring for each household is high, and the use of heating Expensive cost, low willingness of users to modify

[0003] Specifically, the existing technology one is to install electric furnaces or gas furnaces for each household to automatically control heating to provide heat for each household, and use the amount of natural gas or electric energy measured by each household as the basis for charging energy consumption for each household. Metering is the metering of electricity or gas for each household (such as figure 1 shown); there are three problems in this coal-to-gas coal-to-electricity transformation method: A. This measurement method seems to measure the consumption of electricity or gas, and at the same time solves the problem of household heat measurement

Although this transformation method of coal-to-gas and coal-to-electricity solves the above-mentioned problem C, it can not meet the requirements of household heat metering and still does not solve the problems A and B.
