A/C exhaust pulled through cool tube ...

Trying to make a new cabinet, I am thinking of putting one of those indoor A/C unites that cools 500 sqft, and I am curious if we have any engineers here that could elaborate for me.

I am thinking of pumping the cooled air into the bottom of the cabinet.
The exhaust from the A/C that is supposed to be pumped outside, I am thinking of hooking up to one side of a cool tube with a 770CFM fan on the other side, pushing to the air intake on the A/C.

So a completely closed circuit. Reason being is in past grows I cut massive 8" holes into walls and floors and am hoping to skip that this time. Lol.

That exhaust will be hot air. That's why it is designed to be vented outside.

I would pump air into the room, have your carbon scrubber drawing in air from the cabinet, vented through the cool tube and and have your in line fan pulling the air to outside the growing space.


2 in line fans will work a lot better. One for odur control the other one to keep the light cool.

Edit.. new.phone is killing me with auto correct

Yeah, you mean cut a hole in the wall somewhere

Grow room indoors means holes in wall. Not too many ways around this with high output lights, sorry

If you remove heat and then pump it back into the room, you have done nothing

Pumping the heat into the Air Conditioner air intake. It would drop 15-20 degrees then enter back into the cabinet at the bottom.

Sorry brother. I just don't see the advantage to doing it the way you are describing. A simple fan/carbon filter set up will remove a lot of the heat. I'd have the AC blasting in the room to get sucked into your intakes and get the hot used up air far away.

Like durban says, there really isn't much point to cooling the air right before it enters the intake. Just cool the room itself and properly ventilate the grow area.

The only way you could avoid large vent holes is to have a split air conditioner with refrigerant lines running outside smaller holes, and those refrigerant lines going to an external condenser/compressor. This would make it a closed system, and actually work, although humidity would be through the roof without ventilation.

Thanks church thats what I needed to know.
