That will give us 3, second per hour. So if we divide 12, kJ by 3, seconds per hour, then that gives 3. In the image above you can see example calculations for how to convert between different, common, refrigeration units. Save my name, email, and website in this browser for the next time I comment.

I am mech engg student and interested to know that how much electrical power a refrigerator so that it can run by solar energy using panel. I am working on solar system design. Unfortunately you are confusing readers, these calculations are wrong in view of power consumption, as the calculations are based on the amount of heat transfer which different from the compressor power consumption, actually I measured the current of 1T AC and it was about 6A and was 12A for the 2 ton AC.
I couldnot understand it properly.. Now I Have to take a connection for 4 no of 2 ton carrier split AC. Now how much KWA connection I have to apply? Would like to clarify the explanation above as it is misleading. Tons of refrigeration in terms of watt is different from electrical power input needed in terms of watt to suffice the requirement needed by a room. The first is about heating and cooling, mechanical in nature. It is the result of converting electrical energy by a unit, say a motor to run the compressor mechanical for heating or cooling.
For the electrical power, it pertains to the power input needed by the motor or the HVAC system to achieve the heating needed by a room. It is the ratio of cooling provided by a unit or heating divided by the amount of electrical input power required to achieve it.
Here in my place, air conditioning units typically only show EER of the equipment as we only have 2 seasons. Now for example, a window type air conditioning unit, typically it has an EER of around 9 to 11 bu we may use 10 for illustration. In terms of watts of heating and cooling for this specific equipment, it would give you around W. In addition, the recommended cooling area could be up to around 16 square meters.
To note, I have computed it in a reverse sense meaning to the point of electrical, though, in reality, you compute first for the heating and cooling requirement of the room before determining the needed machine to achieve it. An excellent article, thank you. Tons as a measure of cold makes so much sense; before reliable mechanical refrigeration came along, things were kept cold with blocks of ice.
Where I live, Cambodia, that is still very much the case today. Doubtless that was how coolrooms and the like were monitored and measured until the latter part of the 19th century.
