Ducting a ductless minisplit
I have read of the problems with the distribution of hot air and cool air in well sealed and insulated houses, and I have a “boss” who dislikes the looks of minisplit indoor units. But we don’t need more heat or cooling than a Mitsubishi Hyper Heat can provide.
I’m thinking of locating a minisplit’s indoor unit in a closet with a small air handler (like Electro Industries HE-N-00-21). The closet would have a return air duct under the air handler and an outlet duct through the floor under the minisplit. A “shelf” would run horizontally around the minisplit and the outlet duct of the air handler
With the closet door closed, there would, in effect, be a “plenum” above the shelf, pressurized by the air handler. The air handler’s ECM motor would overcome the friction losses of the ductwork. The ducts through the closet floor are connected to a conventional forced air heating/cooling duct network.
Has anyone done something similar? See any problems?
