TR ( Ton of Refrigeration) is the unit used to measure the capacity of an air conditioner. But some people get confused about this unit. So lets understand TR.
Ton of Refrigeration can be defined as, heat required to completely melt down 1 ton of ice in 24 hours or heat removal required to convert 1 ton of water to ice at 0 degree C is 1 Ton of refrigeration.
1 TR = 12000 BTU
where the above equation came from
according to definition of 1 TR -
A water-chiller refrigeration ton is defined as:
1 Refrigeration Ton (RT) = 1 TONScond = 12000 Btu/h = 200 Btu/min = 3025.9 k Calories/h = 12661 kJ/h = 3.517 kW
1 kW = 0.2843 Refrigeration Ton (RT)
A ton is the amount of heat removed by an air conditioning system that would melt 1 ton (2000 lbs.) of ice in 24 hours. The heat required to melt 1 lb of ice at 32 oF to water is 144 Btu.
1 Ton Refrigeration = (2000 lb) (144 Btu/lb) / (24 hr)
= 12000 Btu/hr
