Mini split btu?

Just wondering how many BTU of ac to cool a 13x16 room with 2- 4x10s with 3000 watts of cobs.each 4x10 has 30 Vero 29s @50 watts per cob.
I ordered already but can send back if I need to.i was thinking 18000btu but thinking I may need a single 24000.
Walls have r13 and 2 inches of foam on exterior and r30 in the ceilings.

My 12,000btu mini has done good to around 3000 watts of COB's. My rooms not big enough for any more wattage, 75sq/ft., so, not sure if it could handle more.

if I remember well, in residential application you need 12000 btu per 700-800 sq/ft, in commercial/industrial you need 12000 btu per 400-500 sq/ft, I cool and dehumidify a 30sq/ft space with a 5000 btu window shaker, I have 1k hps and 600watts of leds, I'd suggest no more than 12000 btu unit, this way you won't short cycle your unit and will dehumidify before cooling.

Bump

it reaaly depends on your climate/location. ive always sized it to be 4000 btu per light, which is what i need during summer. way less in winter. places like socal need 6000 btu per 1000 watts. thats enough.

i get the 4 ton heat pump units off heatandcool.com. there 2700 but do about12 lights for me. i wouldnt suggest buying anything else unless you dont plan on upgrading...

The calculation that has worked for me is
Whatever you need for that room for the hottest months of the year if you were just using it as a living room + (3.4 btu per watt of light x 1.5) = Mini Split BTU’s.

It really depends. A basement is much easier to deal with compared to metal prefab barn without insulation. Even the type of ac matters. Avoid portables imo. Go minisplit with heathpump and buy bigger to avoid upgrades.

Mine are all like this but kilmaire

what ever u do man
make sure u get mutli head units .......i say a 24k btu is more then enought 2 12k head units so it can do bothsides of the room at same time using a 24k compressor

a 48k on cobs is overkill even for me in that small of a room

depending on how u are setting it up u can buy in wall fans that will move air for u aslong as the remote or head units can get a clear since of the temp in the area should be fine and with whole thing inclosed could do Co2 just put in 2 fans one low and one high when it is night time just reverse the fans blow from the top suck from the bottom will lower co2 and increase oxygen in the area for off time

I haven’t used AC in about 8 years but that’s an awesome method to put more than one wall fan unit in the room. Better distribution and redundancy. Very cool! Ha! Get it?? Very COOL.

I'd suggest a Mini split 24000 Btu / 2 Ton (800-1200 Sq Feet)

That's what I got.mr cool.shit works flawless.keeps the temp right on point with 4000 watts of lights and 2 water chillers.

What I like about these systems is that eliminate the need for a basement or attic-located evaporator unit and bulky ductwork by using thin copper tubing that pumps refrigerant directly to discreet wall mounted or concealed units inside.

Copper tubing running through a small 3 to 4-inch opening in the wall or ceiling easily connects the indoor and outdoor units.

Really easy
