Hello, I recently saw a job in the centre of London and the chiller in the basement plant room has dual port PRV valves that would vent directly into the plant room. I have been asked to reroute the PVR to a different location. However I don’t know were to vent the PRV's to?
I could vent them into the evaporator, or to atmosphere? Would I be correct if I ran pipework from the PRV's directly out the plant room into the car park or are there regulation in place we this refrigerant should be vented too ?
I understand that PRV valves are for safety reasons and will only let go in the case of a fire or extreme operating conditions.
