Theoretically yes, but you can be more effective with two in some respects because you can spread the cooling, if the unit isn't powerful enough to cool the entire area and it's contents, then you can at least spot-cool two small areas.
Having said that, it's better to provide enough cooling for the entire area.
There's a cooling sizing guide in my related link. I would say two 12,000 BTU portable units are probably far cheaper than one 24,000 BTU, maybe even three... So you could get more cooling out of small cheap ones probably.
The Amps means the volume of flow of electricity. The Amps depends on its BTU (British Thermal Unit). BTU is the unit to measure the energy that is consumed to perform some Air Conditioner. 12000 BTU Air conditioners uses 5 to 6 Amps. 18000 BTU Air conditioners uses 9 to 10 Amps. 12000 BTU air conditioners also called 1 Ton AIR CONDITIONER and 18000 BTU Air conditioners are called 1.5 Ton and so on. The 2 Ton or 24000 BTU Air conditioners use 15 Amps to work.
24000
4000
The tonnage is usually found on the nameplate on the condensing unit outside. 12000 btu= 1 ton 24000=2 ton and so forth.
20% of 12000 is 2400. It is equal to .2 * 12000, which would be 24000/10, 2400.
24000 tbsp 1 Ounce = 2 tablespoons 1 tablespoon = 0.5 ounce
600 square feet.
The first 10 multiples of 6000: 6000, 12000, 18000, 24000, 30000, 36000, 42000, 48000, 54000, 60000 . . .
24000 joules
They are infinite but here are the first 10: 2400, 4800, 7200, 9600, 12000, 14400, 16800, 19200, 21600, 24000.
Air Conditioning: 1 Ton = 12000 BTU
