The equation may yield a fraction. One BTU per hour is equal to 8.33333×10-5 refrigeration ton: 1 BTU/hr = 8.33333×10-5 RT . 8 Answers. Choose the 30,000 BTU unit to make sure your comfort needs are covered. Multiples of the watt hour, often the kilowatt hour, are more frequently used than Btu/h, even in the United States. Types of Air Conditioners and Their Electricity Requirements Mini Split Air Conditioner Electricity Requirements. Blueridge technical support information, product brochures and more. 500 square feet = 12,000 BTU. The Basics of Air Conditioner Sizing . BTUs stand for British Thermal Units and refer to the amount of energy your air conditioner is using per hour. To convert BTUs to tons, find the BTU capacity of the air conditioner, and divide the BTUs by 12,000. The number is expressed in thousands, such as 6,000 BTU or 15,000 BTU. Definition: A ton of refrigeration (TR) is a unit of power. History/origin: The ton of refrigeration originated around the 1880s during the transition from stored natural ice to mechanical refrigeration. Relevance. However, amperage draw differs with standard voltages like 115 volts and 230 volts and whole-house central air conditioning. A 2.5-ton air conditioner will move 30,000 BTUs of heat per hour. Some smaller capacity units only require 110/120 volts. Twelve thousand BTUs equals the amount of heat removed by an air conditioner that would melt 1 ton of ice in 24 hours, which is called the chiller refrigeration ton, according to The Engineering Toolbox. BTU to TON Conversion Table Likewise, a “2-ton” central air conditioner is able to cool 24,000 BTUs per hour. [1] X Research source For a rectangular room, multiply the length and width, measured in feet. ONE-4U-2ENVY. 5,000 BTU air conditioners are recommended for rooms less than 200 square feet (ideally less than 150 square feet).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. The BTU is specifically defined as the amount of heat required to increase the temperature of one pound of water by one °F. Also, explore tools to convert Btu (IT)/hour or ton (refrigeration) to other power units or learn more about power conversions. 1400-1500 square feet = 24000 Btu per hour 13. You can confirm that you have a 2.5-ton air conditioner by looking at the metal manufacturer's identification plate on the back of the air conditioner. Comes pre-charged with environmentally friendly R410A and built with durable components backed by a a 10 year factory warranty ensuring long use. Based on the statement, it follows that a 1-ton air conditioner can remove in a span of one hour an amount of heat that is equal to 12,000 BTUs. 750 square feet = 18,000 BTU. Install Kit - 230V/60Hz $2499.00 $2399.00 An old rule of thumb stipulated that 1 ton of air conditioning should cool 400 square feet of living space. They are usually window units. All this info you can get from the ‘Ton to BTU table’ above. For example, the Manual J calculation may say you need 25,000 BTUs for cooling. Here’s a rundown of the range you will encounter: 18 = 1.5 tons, 24 = 2 tons, 30 - 2.5 tons, 36 = 3 tons, 42 = 3.5 tons, 48 = 4 tons, and 60 = 5 tons. 13 SEER - 30,000 BTU Central air conditioner system with 30000 BTU heat pump comes equipped with both condenser and air handler to provide a powerful self-contained cooling-heating system on the market. The electrical current (measured in Amperes or ‘amps‘ for short) needed to run an air conditioner is directly proportional to how much the AC unit will affect your electricity bill. NOAA Hurricane Forecast Maps Are Often Misinterpreted — Here's How to Read Them. Using a calculator, divide the unit's BTU rating by 12,000 to arrive at the chiller refrigeration ton capacity. So now you are likely asking, what is a BTU? For example, 48,000 BTU equals to 4 tons and 60,000 BTU equals to 5 tons. 12,000 BTU is roughly equal to 1 TON. A ton of refrigeration is approximately equal to 12,000 BTU/h or 3.5 kW. The current thinking, according to Green Building Advisor, is 1 ton per 1,000 square feet of space, with some adjustments based on ceiling height, climate, number of windows and other variables. History/origin: The British thermal unit per hour is based on the British thermal unit (symbol: Btu or BTU), a traditional United States customary unit of heat, where heat is a type of energy transfer in which energy moves from a hotter to a colder substance. Sometimes you’ll see air conditioner size measured in tons instead of BTUs. This will give you the total square footage of your space so you can choose a furnace that will adequately heat your home.
