Hi everyone, apologies for my late response. I've attached the schematic of my plant room for your better understanding. I hope this provides clarity. I've designed the system to monitor the temperature and pressure at each heat exchanger. Upon further review, I found that automatic balancing...

Chilled water is supplied to my building from a district cooling plant. I have heat exchangers forming a primary and secondary loop, with a header piping system. I have designed modulating valves at the heat exchangers, installed on the primary side, with temperature sensors measuring the...
