Live in Charlotte, NC...hot, humid summers and relatively mild winters.
We are putting on a 350 sq ft master suite addition with bedroom(~200 sqft), bathroom(~100 sqft) and closet. The space is a 21' x 17' rectangle and there is a partition wall with a pocket door on either side opening off the main room into the bathroom and closet. Bedroom has a vaulted ceiling.
We plan to use a combination of radiant floor heating and a ductless mini-split unit for cooling. We plan to have a Manual J done before determining the final size of the cooling unit (probably 9K of 12K Btu).
My question is will a single unit properly sized and positioned in the bedroom be able to cool/dehumidify the bathroom effectively as well? Right now the plan is to position the mini-split unit high up on the partition wall. Will a higher CFM unit be more likely to cool/dehumidify well?
Any advice and suggestions would be greatly appreciated.
