I am reworking a small room to house a frog exhibit at our zoo and I would like to receive some more feedback before I "hop" in and have a system installed.
The room is 8'x8'x8' and is somewhat insulated on two walls and not insulated on the other two walls (thin wood and glass windows). The room is kind of like a wood shed and stays close to the outside temperature in Southern California which ranges from the 40's to the 90's, I need to keep this room in the 70's throughout the year night and day. The heat load from any electronics in the room is negligible.
I have heard great things about mini-split systems but one person told me the air will get "stagnant" in this small room since there is no fresh air coming in with a ductless system?? Is this a problem I should be concerned about using a mini-split in a room that is only 64 sq feet? There will be misting systems on the tanks to keep the frogs happy, is humidity in the room also going to be an issue? Is there a better alternative for heating/cooling this room? Any help is greatly appreciated.
