We have a Fan Coil Unit and you should know that the air bubbles in a closed system like any coil system could lead to performance problems. You cannot have the maximum performance if your cool/hot water in the coils has more air within it. So we have to release excess air by opening and closing a valve (bolt/screw) and air is trying to escape because there is always water pressure in a closed system. (Every FCU has its own screw for escaping air) Now the question is what is the best situation for releasing excess air? I mean, when the water is circulating or just when the system is shutdown? 1. Release excess air when water (hot/cold) is circulating 2. Release when the pumps are off I don’t know the difference and the better way for doing this, please help me. By the way, I couldn ’t find the technical definition/phrase for this “excess air in circulating water”; would you please tell me what you call it?
