Dual hose portable a/c compatable with CO2 / sealed room.....?

Hello I recently built myself a sealed room in my basement and the portable a/c I have sucks the co2 right out of the room as it is only a single hose model.

** do the dual hose portable a/c really use 1 hose for intake and 1 hose for exhaust????

** does anyone know of any particular models that are good for use with sealed rooms using co2???


THANK YOU!!!

ps I have a window unit mounted in the wall and I didnt think that exchanged air with outside but I am pretty sure that it does actually take co2 out =/ plus it would be a pain in the ass to cover the exhaust side of that window ac and suck the hot air over to the chimney whereas a ducted portable ac all I gotta do is run duct where I have to do.............. thanks for your input!!

Yes. It will work exactly how you want it to work.

Any model will do as long as it's rated with enough cooling capacity for your room. You'll need around 4000BTU per 1kw of lighting.

do not get a portable ........the energy vs the cooling area suxs .......it is not worth it

a window AC depending on the model u have is about 85% sealed so the co2 that passes tho it is dumped back in

if u are doing a Co2 system then u are not dumping air out of the room like in a exchange system .........your best value is a MINI SPILT ductless AC (100% of the Co2 is recycled back into the air )
a mini split ac will cost more but it will do the job 100% no worries (the room will be sealed your Co2 cost will decrease)

as for the dual hose .......no it does not cycle air in both hoses are exhaust to dump the heat it makes outside so it does not heat the room up .....the dual part is becuase the system is big so it needs that CFM moving tho it 1 ducting did not do it so they put 2 in split the load between them so a jet of hot air is not shooting 10 feet out from the window

Potentially 6kBTU per 1k watts if using open hood. Mini-split is definitely the way to go. You can go pretty small,around 7k BTU with a mini split. If you are only planning on one light 7k is good, but if you plan to grow into it you may want to go a bit bigger. I saw some 7K units start at 400ish and 9k's slightly higher. PLUS the efficiency with a lot of the newer mini split units with save you money compared to running the portables.

Dual hose a/c that just cool the condenser need to be sealed up tight around the condenser in some cases and they are very inefficient. The window a/c unit you have likely needs to be sealed also and that's your most economic go to move for now. The best option is either a mini split or another direction you could go is using a water chiller to chill a reservoir of water then pump that water through an ICEBOX. You can research that of course to see if it fits your situation.

I have a 12,000 btu mini split with heatpump and it is the only way to go. Mine is 120 volt and I have only seen it hit 7.2 amps on my wattmeter. Add a home style wall programmer that allows you to set night and day zones ( 60*-75*/65*-85*) It will further reduce your electrical consumption and demand on the unit.
