You are correct ARI conditions are not the same as the manufacturer's of the compressors. If the manufacturer of the condensing unit is ARI certified you can trust the data to be accurate. ARI conditions for condensing are 95F outdoor temperatures and 80/67 db/wb temperatures entering the...
Installing a large evaportater coil should not be a problem here. The lower rated coil brings a much worse problem that of face velocity of the coil. Manufactures often allow a maximum face velocity of 550 feet per minute (fpm) to prevent the water on the coil from blowing off and into the...
The only problem you will have is spending too much on sheetmetal costs. The velocity pressure will simply convert to static pressure. There will be no problems with downstream diffuser flow rates. Overall fan power requirements will be lowered resulting in energy savings provided that the...
