Balance controlling method of heating system and diagnosis measuring device

Abstract

The invention relates to a heating system of a balance controlling method thereof, wherein the diagnosis measuring device is provided with multiple sensors, an analog signal preprocessing circuit, an analog to digital converter, a microprocessor and a digital display, which are connected in sequence, wherein the sensors includes a temperature sensor and any one or any two or all of a flow sensor, a pressure sensor and a differential pressure sensor; the balance controlling method adopts the diagnosis measuring device to detect the water inlet temperature and flow of each balanced heating branch in the heating system, the balanced flow rate of the corresponding balanced heating branch under the balanced heating is calculated according to the detected water inlet temperature, and the actual flow of the relevant balanced heating branch is regulated through a balanced valve to be the balanced flow rate of the balanced heating branch, thus balanced heating is realized. According to the invention, the phenomenon of nonuniform cold and hot is eliminated effectively, which is beneficial to improvement of the comfortability in houses and reduction of the heat energy loss.

Description

technical field [0001] The invention relates to a diagnostic measurement device for a heating system and a balance control method for realizing the heat supply balance of the heating system by using the device in cooperation with a balance valve. Background technique [0002] In the actual operation of the heating system, in order to monitor the operating status of the system, it is often necessary to measure parameters such as pressure, differential pressure, flow and temperature in the system pipeline, but most of the existing diagnostic and measuring instruments for the heating system only have a single The parameter measurement function is very inconvenient to use, the work efficiency is low, and the simultaneity between multiple parameters is not good, so it cannot accurately reflect the real operating status of the system at a point in time. [0003] On the other hand, the balance adjustment of the existing heating system is basically the adjustment of the hydraulic ba...

[0002] In the actual operation of the heating system, in order to monitor the operating status of the system, it is often necessary to measure parameters such as pressure, differential pressure, flow and temperature in the system pipeline, but most of the existing diagnostic and measuring instruments for the heating system only have a single The parameter measurement function is very inconvenient to use, the work efficiency is low, and the simultaneity between multiple parameters is not good, so it cannot accurately reflect the real operating status of the system at a point in time

[0003] On the other hand, the balance adjustment of the existing heating system is basically the adjustment of the hydraulic balance, and its control target is the flow rate of the medium. Although there is a certain relationship between the flow rate of the medium and the heat released by the medium in a specific pipe section, but Since the temperature of the medium on different heating branches is different, the balance of heat supply cannot be achieved by relying on flow balance
