Cooling room while using CO2? Help!

Is welding absolutely required? Since the copper lines are "refrigerator coil", I'd think a good flare connection should do. Is there a code issue? cn

my unit will go down to 12* ambiant temp and still cool the room. without low ambiant some will stop cooling at mid 40's or higher. lg makes very good systems. if you really want to do it right the first time just forget the portable idea and get an inverter minisplit. mine is 12000btu 20 or 21seer in a 6x10 room,2000watts, co2gen, ballasts, dehumidifier, and household water heater and if i wanted i could take room from 80-70 in just a few mins. oh and i dont air cool my lights.
with 4k you might want 18000btu.

dont think i would ever run my room at 87-94.

no welding needed. line sets are available in different lengths and flare connections are used.

if you were to buy a unit and it came with a lineset that was to short, you could extend it by simply brazing/welding in the longer section. you could flare it, but that would require a flare tool and knowledge of how to flare, just like you could weld it, as that requires a torch and knowledge of welding, way less chance of a leak when you weld/braze/sweat it.

To the person who replied first let me clarify again: im already running aircooled lights and room fans.

With 2x1000w lights aircooled by one 8 inch duct fan, my room sits at about 77-79 degrees. But of course adding 2 more lights is the reason im looking into an ac unit.

I think im sold on the mini split, and ill probably end up with the IdealAir brand one since its at my local growshop and the only one in the sunlightsupply catalog. So I know its a decent minisplit.

But they have 13k btu or 26k btu, both with either 13 seer or 15 seer. So a total of 4 options, and I just dont know which one I should go with.. I dont want to undercut myself and have it be insufficient and stuck with it, but I also dont want to spend more money than I need to, so the less the better. But again im not sure.. Considering my current room conditions (aircooled lights and sitting at 77-79 deg) do you guys think a 13k btu will be enough for adding 2 more lights? And also, how big of a diff does 13seer or 15seer actually make?

Just want to get it right the first time, but not waste extra money on a bigger unit if 13k btu is enough, because the price jump isn't cheap.

for every s.e.e.r you go up, you save 5-10% on your electric bill. i f you plan in using it A lot. the 15 will save you money and eventually pay for itself in savings.

Ok cool thanks.
So if all its doing is saving in electricity, I might go for the 13seer only because its such a big price jump and funds are tight but hopefully not for long.

So now the real question is, do I need the 24k or will the 12k be enough for my room? (By the way I realized they come in 12k and 24k not 13k and 26k like I stated earlier).. On the website it states 10-12k btu is suggested for 4000w. So I think it will make due, but of course thats not taking room size or anything into consideration.

So I ask, will the 12k btu be sufficient? Or must I get the 24k?

Well, I think the difference in SEER rating will only pay for the higher price of the unit over YEARS. But anyways, I have a 2 ton(24,000 Btu's) mini split(13 Seer). What you're looking at is a smaller form and diff. shape of a central air unit sitting outside the house/building. The farther away and more difficult is is to run those those lines, the more money it's going to cost you.

I just had to go through one wall that was shared with my room and the outside. I had quotes from $900-$600 and then finally a guy that did it for $300(total install). Figure about $80/hour plus any gas or something they need to use on the unit.

DON'T buy a unit from the hydro store!! That would prob. be the most you'll over pay anywhere. I forget the exact website but just google "minisplitwarehouse.com" Hell, that may be the exact site...They have all kinds of units, ratings, high and low end/prices etc.

I bought a Shinco but they have units on there called Mr. Whisper and they're just plain awesome prices...MANY others too though. Just be sure to do your homework before you get "taken" for a min split at the hydro shop........
