Problems solved by technology

[0004] (2) The difference between the user's actual flow and the design flow will cause unreasonable heat distribution
[0005] (3) In the actual operation process, users with higher room temperature will transfer heat to adjacent rooms with lower room temperature, which will cause the valve opening time of users with high room temperature to increase compared with the normal heating of neighbors, and more heat will be shared. This unreasonable situation If the difference is large, the "on-off time area method" that apportions heat according to the cumulative opening time of the valve and the heating area cannot be accepted by users, and its promotion and application will be limited.
[0010] To sum up, there are still many problems that have not been solved or overcome at present, according to the "on-off time area method" of apportioning heat according to the cumulative opening time of the valve and the heating area.

Embodiment Construction

[0092] The technical scheme of the present invention will be further described in conjunction with drawings and examples below, but it does not constitute a limitation to the claims of the present invention:

[0093] Such as figure 2As shown, the heat meter at the thermal entrance of the building measures the total heat of the building, and uses this as the basis for the heating charge of the building. Install a room temperature on-off control valve on each user branch pipeline, and set a room temperature controller in the room. The room temperature controller measures the room temperature and at the same time transmits the measured room temperature signal and the room temperature signal set by the user to the room temperature on-off control valve through wireless or wired means, and the room temperature on-off control valve controls the on-off of the valve through its built-in room temperature control strategy , so as to control the user's room temperature, and calculate th...

Abstract

The invention relates to a centralized heating heat allocation method and system suitable for an on-off adjustment mode. The heat allocation method includes the steps that heating heat consumption is calculated through an on-off time and area method, and heat allocated to each house is calculated through a built-in special calculation method according to the user indoor temperature and the outdoor temperature which are measured in real time. The heat allocation system comprises an indoor information acquisition module, an on-off control module, an information acquisition and allocation module and an outdoor information acquisition module, wherein the indoor information acquisition module is used for measuring the indoor temperature; the outdoor information acquisition module is used for measuring the outdoor temperature; the on-off control module is used for conducting on-off control on a valve according to the indoor temperature fed back by the indoor information acquisition module; the outdoor information acquisition module transmits the acquired outdoor temperature to the information acquisition and allocation module which allocates heat according to the method.

Description

technical field [0001] The invention relates to a method for apportioning heat in a central heating system based on an on-off adjustment mode, and belongs to the field of heating, ventilation and air conditioning. Background technique [0002] The "heat supply reform" centered on "household adjustment" and "metering and charging" is an important part of my country's building energy conservation work. JCJ173-2009" and Chinese patent "A Method and System for Simultaneously Realizing Heat Regulation and Heat Metering" (Application No. 200610114686.2 Application Date 2006.11.21), provide a user heat allocation of "on-off time area method" measurement method. This method achieves the purpose of controlling the room temperature by on-off control of the user's heating circulating water. At the same time, based on the accumulated valve opening time and heating area of ​​each heating user, the heating heat consumption of the entire building is allocated and charged according to the he...
