Heating system heat metering and heat energy-saving control method and special device thereof

Abstract

The invention provides a heating system heat metering and heat energy-saving control method and a special device thereof. The method comprises the following steps of: calculating heat exchange quantity according to the water inlet and outlet temperature and the flow of a heat supply network pipeline through a controller, wherein the heat exchange quantity is used for metering building heat and serves as the basis of building heating charge; setting an initial target temperature value through the controller, correcting the initial target temperature value in real time according to outdoor environmental temperature, building load characteristics, indoor temperature and energy-saving control strategy so as to obtain a real-time target temperature value, and arranging at least one secondary heat supply network temperature sensor on a water supply and return pipeline of a secondary heat supply network pipeline; comparing the temperature value acquired by the secondary heat supply network temperature sensor with the real-time target temperature value, and correcting. The heat is regulated and controlled when the heat is metered. Therefore, the heat supply is regulated according to the building heating load, and the heating energy consumption and cost are reduced.

Description

technical field [0001] The invention relates to a control method and a special device for a heating system. Specifically, it relates to a heat metering and heat energy saving control method of a heating system and a special device thereof. Background technique [0002] Energy conservation is an inevitable requirement for the country and society to achieve sustainable development. At present, my country's building heating energy consumption is relatively high, the main reason is the lack of household metering and charging for heating, and the waste of heating is serious. [0003] The Ministry of Housing and Urban-Rural Development, the Development and Reform Commission, the Ministry of Finance, and the General Administration of Quality Supervision, Inspection and Quarantine issued the "Opinions on Further Promoting the Reform of Heat Supply Metering" (Jiancheng [2010] No. 14), requiring newly completed buildings in northern heating areas and the completion of heat supply met...

AI Technical Summary

Problems solved by technology

[0005] First, heat meters are generally used for heat measurement, but the existing heat meters do not have the function of heat regulation and control, and cannot adjust the heating temperature and heat supply according to the building load demand

At the same time, the operating costs of primary heating network system equipment such as water pumps and boiler equipment are relatively high

[0006] Second, specialized operators can control the heat supply by adjusting the valves on the pipelines of the system, but it is difficult to meet the changing needs of the building's daily heating load, and the system operation and pipeline costs increase

In order to meet the heating effect, a higher heating temperature is used every day, and the indoor comfort of the building is poor, which leads to the waste of heat supply and increases the heating cost of users

[0008] Fourth, in the current household metering transformation, if the current heat meter is used and the heat supply control is realized, the user needs to add a dedicated heat quality control system, which leads to a substantial increase in user investment
