A heating control and heat metering method at the user side of a central heating system

Abstract

The invention provides a unit user side heating control and heat measurement method of a central heating system. Each unit user is provided with an indoor control unit, and each indoor control unit comprises a set temperature management unit, a window opening monitoring unit, a room position management unit, a unit for monitoring whether a person exists or not, a valve management unit and a data integrating unit; a heat-supply pipe network inlet of a building where each unit user is located is provided with a heat meter, and the data integrating units calculate the heat using amount shared by all unit users according to the received data and data measured by the heat meters. According to the method, the factors of the room position, whether the person exist or not, whether a window is opened or not and the like are considered at the same time, the heat fee sharing is fair and reasonable, and the method is easily popularized and accepted by the public.

Description

technical field [0001] The invention relates to the field of central heating, in particular to a heating control and calorie measurement method at the user side of a central heating system. Background technique [0002] The charging mode of the central heating system is generally that each household pays a certain amount of heating fee according to its building area. The disadvantage of this method is that the heating fee paid by the household is fixed regardless of the actual heat consumption of the household. This is not conducive to the economical operation and control adjustment of the heating system. The temperature of some users at the unfavorable end is not up to the standard, and some users near the heat source end are overheated and need to open windows to dissipate heat. It is unreasonable for these users to pay the same fee At the same time, it also caused a lot of energy waste. In view of this situation, the household control and heat metering technology of the h...

[0002] The charging mode of the central heating system is generally that each household pays a certain amount of heating fee according to its building area. The disadvantage of this method is that the heating fee paid by the household is fixed regardless of the actual heat consumption of the household. This is not conducive to the economical operation and control adjustment of the heating system. The temperature of some users at the unfavorable end is not up to the standard, and some users near the heat source end are overheated and need to often open windows to dissipate heat. It is unreasonable for these users to pay the same fee At the same time, it also caused a lot of energy waste. In view of this situation, the household control and heat metering technology of the heating system are important means to solve the above problems, mainly divided into the following methods: at the entrance of the heat pipe network of each building Meters are set up at each place, and each household shares the total heating fee according to a certain method, or each unit user independently installs a heat meter and bills separately

Although the second method is more accurate in measurement, each household has to install a heat meter independently, which is costly and requires a major transformation of the existing heating pipe network, so it is more difficult to popularize and apply. One way, it is necessary to carry out detailed research on the specific method of allocation, try to make the allocation method fair and reasonable, and eliminate the interference of various interference factors, so as to have the premise and basis for popularization and use
