1 ton of AC deliver 12000 BTu/ hr; what is mean by BTu/hr ?

Question

12000 BTu = 3000Kcal / hr

Answer 1

*BTu/hr =British thermal unit per hour.
Yes, 12000 BTu
= 3000Kcal / hr
=50kcal/min.

Please read below:

*TR=Ton of Refrigeration.

(The cooling capacity of older refrigeration units is often indicated in "tons of refrigeration". A ton of refrigeration represents the heat energy absorbed when a ton (2000lbs.) of ice melts during a 24-hour day. The ice assumed to be solid as 32 degrees F. (0 degrees C.) initially and becomes water at 32 degrees F. (0 degrees C.). The energy absorbed by the ice is the latent heat of ice times the total weight.
Today, refrigeration units are often rated in Btu/hr. instead of tons. The Btu equivalent of one ton of refrigeration is easy to calculate. Multiply the weight of one ton of ice (2000lbs.) by the latent heat of fusion (melting) of ice (144 Btu/lb.). Then divide by 24 hours to obtain Btu/hr.

One ton of refrigeration effect= 2000 X 144/24
One ton of refrigeration effect= 288,000 Btu/24 hours
One ton of refrigeration effect= 12,000 Btu/hr.)

A 12,000 Btu/hr cooling capacity is equivalent to one ton of refrigeration.

Answer 4

1 BTU (British Thermal Unit)= 251.98 calories

In HVAC jargon a ton of airconditioning is 12000 BTU's /hr.

In your example, that means a 1 Ton AC will move 12000 BTU's in an hour, or 3,024 Kilo-calories.

Answer 5

A 1 ton AC can move 12000 BTU (British Thermal Units) of heat in one hour.

Answer 6

One ton of air conditioning is equal to 288000 BTU's in a 24 hour period. In the HVAC industry we talk in terms of 1 hour not 24. So one ton of air conditioning can also be defined as 288000 BTU's divided by 24 hours or 12000 BTU/hour. This rating is the amount of heat that can be displaced by the particular unit. It has nothing to do with how much power the unit will consume. A little more history on the origin of the "ton of air conditioning" is it is actually the amount of refrigeration produced by melting one ton of ice at 32 degrees Fahrenheit in 24 hours.

*Read following: M is the Roman numeral prefix for 1000 and an MBH is 1000 Btu/hr. MMBTU one thousand thousand British Thermal Units MBTU one million British Thermal Units per hour. MBTU one thousand British Thermal Units (original definition, M = thousand; less common) 1 refrigeration Ton = 12,000 Btu/h cooling is absolutely correct.So, 1Ton=12MBH [The unit MBTU was defined as one thousand BTU presumably from the Roman numeral system where "M" stands for one thousand (1,000). This is easily confused with the SI mega (M) prefix, which multiplies by a factor of one million (1,000,000). To avoid confusion many companies and engineers use MMBTU to represent one million BTU.] So, its all depends upon you what you mean by "M".

Answer 8

One British Thermal Unit (BTU) is a mesure of ENERGY or WORK and is the amount of energy needed to raise the temperature of one pound (lb) of water by one degree F.

One BTU/hr is therefore a measure of POWER.
