Low CFM of Concealed Slim Ducted Minisplits
How do people deal with low CFM of concealed/slim ducted minisplits?
Most slim duct or concealed ducted air handlers put out max 350cfm, whether its a low static or high static model. These are often recommended to use for multiple bedrooms so as to not over size with multisplits. But as an example, if I want to use a 9k or 12k air handler to supply 3 spaces, each needing 3kbtu/h according to manual J, each room will get max 100cfm, and only from 1 supply register, and likely not in the floor, usually high up in a wall. Is that CFM enough? and if not, what are the solutions?
