Heat exhaust question

I'm upgrading from 150w hps to a 400w digital for mh/hps & more lumens etc..
I will have ducting with a 200+cfm inline pulling air from the cooltube which will also be pulling used air from the tent. I was wondering if exhausting that air to directly in front of a window ac unit would somehow replenish the used air & cool it down making it reusable again? Trying to think long & hard about exhaust and intake but keep running into brick walls. With not a lot of options.

anyone know?

Not exactly sure what you are looking for. If you take 80 degree air and run it through an a/c unit about the best you will get it a 20 degree cool down. 80 degrees in 60 degrees out. Now as the room cools down 75 degrees in 55 degrees out of the a/c. This is just to a certain point. Coolest air I have seen on an a/c functioning properly is around 48 degrees. And that was with a very cool house.

Sorry for the slow reply but I was wondering if exhausting the hot used air from the hood & grow tent to directly infront of the ac were its blowing out cold air would replinish the air. Since the ac unit is blowing in fresh cold air.

I'm also not talking about exhausting the air through the ac, Im talking about exhausting the grow tent air directly were the ac unit is blowing cold air into the room so it will make the cold air from the ac mix with the hot used air. I thought that might replenish the air making it reusable again for the plants & cool at that.

the air in the tent has been used it has no more effective use to your area other then to transfer the heat out of the area .........daylight the plant uses Co2 and releases Oxygen (recycling the Oxygen into the tent does not benefit u in any way in fact it hurts u ) inside air has a naturally higher Co2 lvl then outside air normal it is double the outside rate 300 ppm

so the most effective way to do this ....is to eject the air used in the tent to the outside completely dumping it out of your cycle ......the air should be drawl in from low to the ground in the house (this is the coldest air plus most Co2 as Co2 is a heavy gas it sinks ....think water and oil water is Co2 Oil is Oxygen)

See I did not know this, So In fact the Co2 levels inside are much more richer and healthier for plants then?

yes that is why the plants in the house always seems little greener and grows lot faster

and not healthier the plant just has more power to use
light
soil/nutrients
water
Co2

during light the plants use Co2 as power and convert it to Oxygen ........at night it uses Oxygen and makes a waste form of Co2 it can not use
the CO2 the plants use come from US living things and chemical reactions like yeast and sugar and other little micros in worlds breaking stuff down for food
