so I put a 6" 5' R6 value insulation sleeve on my a/c exhaust ducting (the 5' section that connects to the unit itself), I dropped my ambient room temp by 4* in about 1 hr, and has held that for the last 3 days. I bought another 3 sections of the 6" 5' R6 insulation sleeves to put on more of the a/c exhaust ductwork. I run a total of 20' 6" added duct work from unit to exiting my building. I also run a 6"440cfm fan (on speed controller) to help get the exhaust air out the house as the ac unit exhaust fan I don't want to burn out. dropping my new 14kbtu in this weekend. im hoping with the new 14k and insulated exhaust ducting my ambient room temps will be 73* or lower.
currently my room is 79* 81* 81* under each hood (3 hoods), 73* outside flower room floor temp, 65* incoming a/c air, 73* exhaust air from scrubber. I have tons of rh and temp gauges I snagged from my curing box. :)
