A method for automatic adjustment of hydraulic balance of heating pipe network

Abstract

A method for automatically adjusting the hydraulic balance of a heating pipe network. It connects the wireless indoor temperature collector, the water supply and return temperature sensor at the head of the building, and the electric control valve on the return water pipeline with the computer control unit. The radiator area, outdoor temperature and other parameters are calculated, and then the electric control valve on the return water pipeline is controlled to automatically adjust, and the adjustment results are fed back at regular intervals, so as to realize real-time monitoring of the entire heating system. And make adjustments at any time. The method reduces the labor intensity of the staff, and takes the user's indoor temperature as the target, and the adjustment effect is intuitive and reliable.

Description

technical field [0001] The invention relates to a method for automatically adjusting the hydraulic balance of a heat supply pipe network, in particular to an automatic adjusting method for adjusting the hydraulic balance by studying and changing the return water temperature to adjust the indoor temperature. Background technique [0002] With the further improvement of energy-saving requirements, room temperature compliance requirements and refined heating management requirements, the demand for scientific and rational adjustment of the hydraulic balance of the heating network is becoming more and more intense. The user's indoor temperature is 18±2°C. Due to the distance from the heat source, the newness of the residential buildings, and the insulation effect, the indoor temperature of some users cannot fully meet the heating standards. The imbalance of hydraulic working conditions is common in the heating pipe network, often resulting in overheating at the near end and overc...

[0002] With the further improvement of energy-saving requirements, room temperature compliance requirements and refined heating management requirements, the demand for scientific and rational adjustment of the hydraulic balance of the heating network is becoming more and more intense. Due to the distance from the heat source, the newness of the residential buildings, and the insulation effect, the indoor temperature of some users cannot fully meet the heating standards.

The imbalance of hydraulic working conditions is common in the heating pipe network, often resulting in overheating at the near end and overcooling at the far end, which not only reduces the efficiency of the heating system but also deteriorates the quality of heating supply. At the same time, energy consumption and operating costs increased badly

[0003] In the absence of a flow meter, the opening of the branch line valve and the valve at the head of the building is generally adjusted step by step through the indoor temperature feedback from the room temperature monitoring tables set in different areas, thereby gradually adjusting the hydraulic balance of the branch line. The method only refers to the data of the indoor temperature, and cannot realize the "adjustment on demand" of the heat, and needs to adjust each valve repeatedly, the effect is lagging, time-consuming, labor-intensive, labor-intensive and energy-consuming, and sometimes the balance cannot be achieved even after multiple adjustments
