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). Many manufacturers also specify capacity in BTU/h, especially when specifying the performance of smaller equipment.

Now if you want to reduce theoretical concepts down to rules of thumb, the standard volume flow rate per unit of power in the HVAC industry is 400 cfm per ton, and a ton is 12,000 BTU's per hour, so 400 cfm per 12,000 BTU's per hour of cooling capacity.

A ton refers to the amount of heat it takes to completely melt a ton of ice. Melting this amount of ice requires 286,000 Btu (British thermal units). How fast the ice melts depends on how much heat it receives over time. ... Rounding up 11,917 Btu/hr gives you 12,000 Btu/hr, which is one ton of air conditioner capacity.

The use of tons to measure cooling capacity comes from this time. A ton refers to the amount of heat it takes to completely melt a ton of ice. Melting this amount of ice requires 286,000 Btu (British thermal units). ... Rounding up 11,917 Btu/hr gives you 12,000 Btu/hr, which is one ton of air conditioner capacity.

A ton of refrigeration (TR), also called a refrigeration ton (RT), is a unit of power used in some countries to describe the heat-extraction capacity of refrigeration and air conditioning equipment. A refrigeration ton is approximately equivalent to 12,000 BTU/h or 3.5 kW.

Divide the number by 12 (which represents 12,000 Btu/hr, or one ton of cooling capacity) to get your AC unit's tonnage. If you don't want to do the math, here are the numbers you're looking for and their corresponding tonnage: 18 = 1.5 tons. 24 = 2 tons.

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.

A British Thermal Unit (BTU) is a measurement of heat energy. One BTU is the amount of heat energy required to raise one pound of water by 1ºF. Water weighs 8.33 pounds per gallon so we can calculate that one gallon of water requires 8.33 BTU to raise the temperature 1ºF.

1 POUND OF WATER requires 970.4 btu's added to water already at 212 degrees to convert to 212 degree steam (at atmospheric pressure, or 14.7 lbs. absolute). ...and when converted to steam will occupy 27 cubic feet at atmospheric pressure, 4.43 cubic feet at 100 lbs.

Most air conditioners have their capacity rated in British thermal units (Btu). A Btu is the amount of heat necessary to raise the temperature of 1 pound (0.45 kilograms) of water one degree Fahrenheit (0.56 degrees Celsius). One Btu equals 1,055 joules. In heating and cooling terms, one ton equals 12,000 Btu.

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.

MMBTU. 1 MMBtu is equal to 1 million BTU (British Thermal Unit). Natural gas is measured in MMBtu's. 1 MMBtu = 28.263682 m3 of natural gas at defined temperature and pressure. 1 standard cubic foot of natural gas yields ≈ 1030 BTU (between 1010 BTU and 1070 BTU, depending on quality, when burned).

The wattage of 5,000 BTU air conditioner units averages 446 to 580 watts (most of the units assessed for this average were window units, as 5,000 BTU split units are uncommon). People often buy 5,000 BTU air conditioners for college dormitories and small apartments. They are usually window units.

There's a complicated mathematical formula involved in converting the weight of that ice into energy, but in the end a “ton” of air conditioning capacity represents roughly 12,000 BTU per hour. So a 2-ton unit has 24,000 BTU/hr capacity and a 3-ton has 36,000 BTU/hr, and so on.

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.
