Condensation Issues
Hi All,
I have a large property that has hundreds of Mini-Splits (wall mount Indoor units) installed in high humid conditions. The issue is abnormal condensation on the factory piping at the connection of the manifold of the Indoor.
At first inspection, I noticed all piping insulated seperately from outdoor unit to Indoor flare connections. I did notice on the factory side of the flares the liquid and suction pipes are insulated together.
I know a few items that would cause excessive condensation such as:
excessive piping lengths (over recommended)
dirty Indoor coils
air gaps between piping and insulation
excessive piping bends (creating pressure drops)
wrong piping sizes
refrigerant charge
But from what I have listed, is there any other things I should be checking? These usits are installed in a really high humidity area, and I also wonder if they are sized in proportion of the load.
I welcome and really need alot of comments as I know you guys know much more than I on these Mini splits.
Thanks to all who respond!
