Technical Introduction
The heating system is a complex, closed-loop system comprising a heat source, a district heating network, and heat users. During operation, factors such as design, construction, commissioning, renovation, expansion, initial balancing, and the varying stages of building development can lead to mismatches between the flow distribution in the network and the demand at individual heat users, resulting in thermal imbalances characterized by uneven heating and cooling. To address these issues and enhance the operational efficiency of heating utilities, our system incorporates whole‑network balancing. Based on the overall network load, pipeline characteristics, and heat‑source parameters, the system employs temperature‑based and heat‑quantity‑based algorithms to distribute the heat supplied from the power plant or primary station evenly across the network via a balanced operating mode, assigning optimal valve openings for each secondary heat exchange station and public buildings.
Primary-side hydraulic balancing
The smart heating platform collects real-time monitoring data—such as temperature, pressure, heat flow, and valve opening degrees—from the primary network of all heat exchange stations. This data is fed back to the heating system, which, based on user‑defined settings and mechanistic models, and leveraging online hydraulic balancing analysis, determines a comprehensive control strategy for the entire network. It calculates the most unfavorable point in the network along with its relevant parameters, conducts an integrated analysis of all heat substations, and retrieves operational data for heat sources, pipelines, and substations across the network. Finally, it issues commands to adjust the opening positions of electric control valves and the operating frequencies of circulating pumps at each substation, thereby achieving thermal balance throughout the district heating network.
Secondary-side hydraulic balancing
Due to factors such as terrain, pipeline configurations, and distance, uneven heating—where some areas receive excessive heat while others remain underheated—is common within the service area of a single heat exchange station. Simply increasing the supply heat flow not only exacerbates overheating in already hot zones but also leads to unnecessary energy consumption. The system acquires user‑side heating parameters and uses model‑based calculations to guide adjustments to valve openings on the user side. When on‑site control valves lack built‑in automation, the system can provide adjustment recommendations to assist manual valve adjustments, thereby achieving hydraulic balance across the terminal distribution network.

Frequently Asked Questions
Precautions for Shutting Down a Plate Heat Exchanger
When shutting down the heat exchanger, first slowly close the hot-side inlet valve, then slowly close the cold-side inlet valve, and finally close both the cold- and hot-side outlet valves. After all valves are closed, stop the pump; if necessary, open the drain valve.
Precautions for Starting a Plate Heat Exchanger
Inspect the clamping bolts and tighten them to the specified torque, ensuring even diagonal tightening. Verify that the inlet and outlet valves and the vent valve are in good condition and that all instruments are functioning properly. During startup, vent the system first, then introduce the cold medium before introducing the high‑temperature medium. Gradually open the inlet and outlet valves while carefully controlling the pressure differential between the two sides.
Precautions for Disassembling Plate Heat Exchangers
Before dismantling the plate heat exchanger, the clamping dimensions shall be measured and recorded. L; Loosen the clamping bolts alternately in a diagonal sequence.
Precautions for Storing Plate Heat Exchangers
Plate heat exchangers should be stored in a dry, well-ventilated warehouse, with the ambient temperature not exceeding 45 °C 。
When a plate heat exchanger has been out of service for more than six months, the internal fluid must be completely drained. It is advisable to loosen the clamping bolts in advance to ensure that the gap between the two clamping plates reaches 1.2 times L is recommended; clamp it to L when in use.
Causes of Leakage in Plate Heat Exchangers
1) Gasket aging; 2) System overpressure; 3) Loose clamping bolts causing external leakage; 4) Plate corrosion leading to internal leakage.
