BTU Calcs for AC ?

[MedResearcher]

I am trying to calculate and pick out the right size AC for a sealed room. The question I have is, how many BTU's do I need for each air cooled 600w lamp. Also how many BTUs needed for a Co2 generator.


I know I saw a basic rule of thumb somewhere here about BTUs per 1000w lamp, although they were not air cooled. Hopefully someone can chime in with some info.


Tks,

You're asking a tough question. The air cooling adds a large variable. Probably the best thing to do, is to make sure that your aircooling is as efficient as possible. Use insulated ducting, be sure to have enough air flow, pull don't push the air, and keep everything as short as possible.

As for calculating watts to BTU I use the Granger catalog, a 1000w electric heater = 3500 BTU.

For the CO2, you might want to look into injecting. Otherwise look into water/aircooled burners. Burners add a lot of heat and humidity to the room, avoid natural gas units because they may introduce impurities.

I use 3 1K HPS and a green air cd-6 propane burner in a sealed 8 by 8 room with a 12K BTU window AC.I have few problems and live in florida.You want flowering temps 10 degrees higher than you would normally run at 1500 PPM co2 anyway.I think I've heard before 3000 BTU per 1K uncooled fixture it just worked out this way for me and works well.How big is your sealed room?The burner puts out less heat than many people imagine when put on a controller.Your burner has to be on a controller or you're wasting your time.Forget about cyclestat timer for your burner,its crap
