Refrigeration tons (RT) to BTU per hour (BTU/hr) conversion calculator and how to convert. Enter the power in refrigeration tons and press the Convert button: BTU/hr to tons conversion One refrigeration ton is equal to 12000 BTUs per hour: 1 RT = 12000 BTU/hr One BTU per hour is equal to 8.33333×10-5 refrigeration ton: 1 BTU/hr = 8.33333×10-5 RT So the power P in BTUs per hour (BTU/hr) is equal to 12000 times the power P in refrigeration tons (RT):

P(BTU/hr) = 12000 × P(RT) Convert 2 RT to BTU/hr: P(BTU/hr) = 12000 × 2 RT = 24000 BTU/hr BTU/hr to tons conversion ► 18,000 BTU 1.5 Ton Ductless Mini Split Air Conditioner and Heat Pump - 220V/60Hz No ductwork for this system, can be installed virtually anywhere Product sold without installation or permitting Equipment should be sized/installed by a qualified professionalRamsond Ductless (Duct-Free) Mini Split Air Conditioning Systems can be installed in virtually any location. Ductless Mini Split Air Conditioners are also referred to as Zone Systems. They cool/heat the zone or areas in which they are installed. When the zone is in use, the mini split system can be turned on. When the zone is not in use, you can simply turn it off. This zone capability allows for substantial energy savings. Ramsond Heat Pump systems not only provide cooling during the hot summer months, but also provide efficient heating for the winter. They are far more efficient and substantially more economical compared to conventional central air conditioning systems.

Ductless Mini Split systems are comprised of two main components: 1) The outdoor unit (Condensing Unit), and 2) The indoor unit (Evaporator Unit). The installation is simple. The indoor unit hangs on a metal bracket (supplied) that attaches to the interior wall, much like a picture frame. A 3 in. hole is then drilled through the wall. The Line set and communication wires are passed through this hole and connect the indoor and outdoor unit together. The Main power is supplied to the outdoor unit. The indoor unit draws its power from the outdoor unit. The system is operated by a wireless remote control (supplied). Simply set the remote control to the desired temperature and the system maintains the desired temperature. Capacity: 18,000 BTU (1.5 ton) cooling 18,000 BTU (1.5 ton) heating (heat pump) + 1000-Watt electric back up heating Power requirements: 220-Volt/60Hz, single phase powered from the outdoor unit Area coverage: up to 800 sq. ft. Functions: cooling, independent dehumidification, and heating (heat pump)

To convert BTUs to tons, find the BTU capacity of the air conditioner, and divide the BTUs by 12,000. 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.

How many BTUs do I need to air condition 600 square feet? How many BTUs do you need in an air conditioning unit to cool a 12 foot by 12 foot room? How many BTUs do you need to cool a room of 435 square feet? Find the BTU capacity On the tag or packaging, find the BTU rating of the air conditioner. The number is expressed in thousands, such as 6,000 BTU or 15,000 BTU.Divide the BTUs by 12,000Using a calculator, divide the unit's BTU rating by 12,000 to arrive at the chiller refrigeration ton capacity. The equation may yield a fraction. For instance, a 6,000-BTU window air conditioner equals 1/2 ton of cooling capacity. Apply the tonnage to the spaceAn old rule of thumb stipulated that 1 ton of air conditioning should cool 400 square feet of living space. However, many air conditioners are too large for the site, which results in high humidity and wasted energy. 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.
