Solution Overview
The solution watches the heat source, the network, the substation, and the household, then balances hydraulics, reads room temperature, and supplies heat on demand. Efficiency goes up, fuel use comes down, and rooms stay comfortable. District heating in northern China is short of heat source capacity, the pipe network is out of balance, and complaints keep coming in. Running “high flow, small temperature difference” burns more coal and electricity than the buildings need.
It is built on IoT connectivity and heating models used by operators. Temperature, pressure, and flow sensors sit on the heat source, the primary network, the substation, the secondary network, and the user end, so the running state is visible end to end. Smart valves trim the network until nearby apartments are no longer too hot and distant ones no longer too cold — heat follows demand. NB-IoT room thermometers report what the household actually feels, and that feedback retunes the source and the substation. Fault alerts, inspection rounds, and dispatch for emergency repairs shorten the maintenance cycle. It fits urban district heating, area boiler plants, and combined heat and power, so operators use less fuel, hear fewer complaints, and run the network in finer steps.
Why Northern Networks Run Hot and Cold
Hydraulic imbalance is common on district-heating networks in northern China. Apartments near the substation overheat; apartments at the end of the line stay cold. Operators answer that by pushing high flow and a small temperature difference, so coal and power stay high. Without a room-temperature reading, the adjustment is still a guess.
Balance valves, room feedback, and heat on demand even out the network and cut complaints. Operators typically report about 10%–15% less energy, which is a real fuel bill across one heating season. One prefecture-level heating company saw complaints fall by about 50% after go-live, once source and substation setpoints followed the room data. Payback is usually two to three heating seasons.
