For stealth reasons, I cannot locate a mini-split unit outside the house. So my plan is to build a box around a window, open the window; and use enough CFM to push the hot air up and out the window, while simultaneously pulling air from the lower point of the window.
The mini-split is 12,000 BTU. I only require 7,000 BTU to cool the room with 30% overhead of BTU's but I want full cooling capability for 12000BTU's from the outdoor unit.
I plan to vent two tents into a common area with the indoor unit and pull the cold dehumidified and co2 enriched air from the common/lung room. Veg is in a 4x8 tent with currently around 600w of light. Flower is in a 4x8 Gorilla tent, with extension; 1200W DE system on a mover. I will use a 745 CFM Vent to pull air from each tent and a 745 cfm fan to move air into both tents. These will be filtered In, and Out.
So as I am designing the outdoor "Hot Box" unit, what is the CFM that will provide enough BTU cooling for the unit to function up to 12,000 BTU without stretch.
Alternately this hotbox will be below the cold air intake and right below the common hot vent for the home so I CAN use holes in the cold air return and home vents to move the air around in the colder months. But the issue is that we get too cold here in winter to run an A/C or Heat Pump anyways; and it gets very hot in the summer. Michigan.
What size vent/carbon filter would be appropriate for 12,000 BTU cooling on the outdoor A/C unit?
