I had always thought that P-trap at the air-handling unit condensate drain connection is needed all the time, no matter if the cooling coil is blow-through or draw-through configuration. However, in the project I am working on, I select a wall-mounted BARD unit with blow through configuration. I was asked why the P-trap is needed. My point is that P trap in the blow through configuration can prevent the cold air at the coil from escaping through the drain pipe. Am I correct here? Anyone can share your experience with BARD unit? Or could you advise anything on this P-trap topic?
Thank you so much!
