how many btu in 1 ton air conditioner?

A ton is the cooling capacity of an air conditioning system. One ton is equal to the amount of heat required (288,000 Btu) to melt one ton of ice in a 24-hour period. A one-ton air conditioner is rated at 12,000 Btu per hour (288,000/24). A two-ton unit would be rated at 24,000 Btu per hour.

It is a Trane 9 SEER 36,000 btu unit. 3 tons = 36000 btu. This XE1000 Nomenclature break down may help. thats a cool chart and made this easier, wish i had that before!

Assuming the minimum cooling capacity of 400 square feet per ton for your HVAC unit, a 1600 square foot home will require 4.0 tons of air conditioning to cool. Your HVAC unit will need to remove about 4.0 x 12,000 BTUs, or 48,000 BTUs, per hour to keep your home cool.

1 ton of cooling is equal to 400 cubic feet of air per minute. 2 ton of cooling is 800 cfm and so on.

The rule of thumb is two to four pounds of refrigerant per one ton of your unit. You should always check the specifications of your unit. However, most home air conditioning units are between one ton and five tons. Anything over five tons is considered a commercial grade unit.

Once you have the base BTUs figured for your home's size, you can then figure out the size of AC and heating units you need. For the air conditioner, divide the number by 12,000 to determine the tonnage required. For the furnace, divide the BTU by the unit's efficiency as a decimal.

Take the 180 sq. ft. times 25 BTU per square foot and you get the minimum BTU air conditioner you should buy. That means 180x25=4500 BTU cooling capacity is needed.

Find the model number. Within this string of letters and numerals, you should find an even, two-digit number. The possibilities on residential units range from 18 to 60. Divide the number by 12 (which represents 12,000 Btu/hr, or one ton of cooling capacity) to get your AC unit's tonnage.

The General Rule of Thumb When estimating the amount of refrigerant in a residential A/C unit, the general rule that is used is in the 2-4 pounds per ton of cooling. Say, for instance, recharging a 3-ton A/C with a 35-foot line set from empty level will need an approximately 6-12 pounds of refrigerants.

A refrigeration ton is approximately equivalent to 12,000 BTU/h or 3.5 kW. Air-conditioning and refrigeration equipment capacity in the U.S. is often specified in "tons" (of refrigeration).

In our opening statement we quoted a rule-of-thumb about air conditioning requiring 400 CFM per ton. This value is usually the basis for rating self-contained air conditioners. Thus, we have a 2-ton unit handling 800 CFM, a 3-ton 1,200, a 5-ton 2,000, a 10-ton 4,000, etc.

Finding the tonnage of your AC unit may be as simple as walking outside and reading the label on the condenser unit. Most of the time, manufacturers don't list tons, though; they list BTUs instead. Lucky for you, we already taught you that math! Simply divide the BTUs by 12,000 to calculate the tonnage of your unit.

A ton of refrigeration is defined as the rate of heat transfer that results in the melting of 1 short ton (2,000 Pound or 907 kg) of pure ice at 0 C (32 F) in 24 hours. The value is defined as 12,000 BTU per hour, or 3517 watts.
