Sizing Automatic Air Vent in CHW system

Sizing Automatic Air Vent in CHW system

Sizing Automatic Air Vent in CHW system

(OP)
Hi,
Would anybody share with me how to size these AAVs on top of rise like these, please?

RE: Sizing Automatic Air Vent in CHW system

I don't think you really "size" them since they are all small and let out a little bit of air. More like you need to select them based on pressure, temperature, and system fluid. Call TACO and ask them what they recommend for your application.

RE: Sizing Automatic Air Vent in CHW system

If you have already identified the need for AAV and not another solution, then it should be selected to match the pipe size it is connected to. So contact manufacturers first.
Where you can make some savings is if you can reduce the quantity of those AAV...
