Where do you find the btu on unit - Heating & Cooling

call fujitsu engineering division direct and ask them about what is connected and if it works ok
logically as each evaporator has it's own tx valve as long as the compressor is large enough to run all together it should work but get the right information from the fujitsu experts

the btu rating will be on the same plate as the model number
if there is no btu rating but a kw rating then there are conversion tables to work it out
for example a 2kw unit is close to 9000 btu and a 8kw unit is around 32000btu

Yes it rated for a maximum out put of 36,000 btu (3 ton) with the right indoor fan coil units which based on the model numbers should give the 36,000 btu's combined when both fan coil units are on, otherwise 18,000 btu's (1.5 ton)per fan coil.

Not every 3-ton unit weighs exactly the same - they differ in weight depending on how they were manufactured. Most 3-ton units weigh around 150 pounds (I would guess) give or take a few pounds.
The "3-ton" refers to the "cooling capacity" of the air conditioner.
It's actually 'slang' for 36,000 Btu.
Note; 12,000 btu equals 1 ton.
Hence a 24,000 Btu unit would be called a "2-ton unit," and a 12,000 Btu unit would be called a 1 ton unit.

Hi,
Look in the model number for numbers like 24, 30, 48, or 60....
They represent the BTU's in thousands of the unit....
The BTU's are 12,000 per ton...
in other words a 24000 BTU unit will be a 2 ton unit

heatman101

divide your btu rating by 12000. (1 ton = 12000 btu)
For example - a 24,000 BTU Air Conditioner is a 2 ton unit. 24000 divided by 12000 = 2
A 18000 btu air condtioner is a 1 1/2 ton unit 18000 divided by 12000 = 1 1/2
you can find out your btu rating by looking on the tag on your unit.

This is a large unit going by the model number.12,000 BTU's per ton. It would be a 5 ton unit, or 60,000 BTU's.

British thermal unit: a unit of heat equal to the amount of heat required to raise one pound of water one degree Fahrenheit at one atmosphere pressure; equivalent to 251.997 calories. The amount of heat needed to raise 1 pound of water 1 degree F (equal to 252 calories).
(British thermal unit) Describes the heat value of fuel for appliances - the higher the BTU, the more heat available for cooking.
A Btu is equivalent to 252 calories and serves as the base unit for measuring the heat content of a fuel source.

Hi,
I found this explanation which I certainly couldn't improve on.

The British thermal unit (BTU or Btu) is a traditional unit of energy. It is approximately the amount of energy needed to heat one pound of water one degree Fahrenheit. One Btu is equal to about 1.06 kilojoules. It is used in the power, steam generation, heating and air conditioning industries. In scientific contexts the BTU has largely been replaced by the SI unit of energy, the joule (J), though it may be used as a measure of agricultural energy production (BTU/kg). It is still used 'unofficially' in metric English-speaking countries (such as Canada, the United Kingdom), and remains the standard unit of classification for air conditioning units manufactured and sold in many non-English-speaking metric countries.
In North America, the term "BTU" is used to describe the heat value (energy content) of fuels, and also to describe the power of heating and cooling systems, such as furnaces, stoves, barbecue grills, and air conditioners. When used as a unit of power, BTU 'per hour' (BTU/h) is understood, though this is often abbreviated to just "BTU".

P.S. PLEASE RATE ME !

The 18,000 btu A/C is 230 volts, are you sure the 12,000 btu unit is 230 volts most are 120 volts.
Usually 12,000 btu is the biggest 120 volt A/C you can buy.
