Hello and thanks in advance for any help you can offer. I will do my best to explain my problem. I have attached 3 pictures which will probably explain my situation better than I can.
*10 ton package HVAC sitting on flat roof
*Ductwork is suspended in dining room about 15 feet high
*Several doors in restaurant that allow heat and humidity in the room which all rises (naturally) to ceiling - where ducts are.
*Cold air being forced into warm duct work creates a drip of varying severity depending on weather / humidity.
*Most times it's right where the cold air comes in the duct and extends about 3 to 4 feet on each side (above dining room tables)
*On really humid days it can extend 10-15 feet down the ductwork
1. I know I could insulate but as the picture shows these are exposed ducts so wrapping them with traditional insulation would look like crap?
2. Is there another kind of insulation / tape with insulating qualities that would provide enough insulation to fix the problem without looking bad?
3. Any other solutions?
The unit has two stages. The second stage kicks in when the temperature dips 2 degrees above set point. I can alleviate the problem somewhat by increasing thermostat to stay out of 2nd stage but then of course the temperature in the room increases and on really hot days that's not an option.
Hope this is enough info. Appreciate any help you can give me.
