Steps to a Health District Heating System
Step 1 - Install a Communications Panel
A communications panel enables wireless communication around a site, as well as remote communication of alarms, reports & commands.
LoRaWAN provides a radio network covering a wide area, removing the need for cabling to sensors around the heat network.
Step 2 - Install Sensors
The performance of a heat network can be determined by measuring temperatures and pressures at key points on the network, including those nearest, and furthest away, from the plantroom.
With LoRaWAN cover from the control panel, the sensors can be located anywhere that one can get power to, and there are ports onto the flow and return pipes that can be temporarily isolated to insert the pressure and/or temperature sensors.
Where power is a problem, a battery powered unit can be used for up to a weeks monitoring, although generally one would be aiming to keep sensors in place permanently to form part of the control system.
Sensors should also be installed at various points on a typical dwelling system or two, to collect data on their operation.
Step 3 - Monitor
A week of monitoring generally provides more than enough data to determine the key issues with a network.
Step 4 - Analyse
Step 5 - Clean
Step 6 - Modify
Step 7 - Setup Alarms
Step 8 - Forget
Step 9 - Alarm Response
