How many kW in a ton of refrigeration?

Some commercial and industrial refrigeration systems are rated in Tons of Refrigeration (TR, tons). 1 Refrigeration Ton (RT) = 1 TONScond = 12000 Btu /h = 200 Btu /min = 3025.9 k Calories /h = 12661 kJ/h = 3.517 kW 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.

How do you calculate a ton of cooling load?

Water flows with 1 gal/min and 10oF temperature difference. The ton of cooling load can be calculated as: Air Conditioning - Air Conditioning systems - heating, cooling and dehumidification of indoor air for thermal comfort. Air Conditioner Efficiency - The ratio between heat removed and power (watt) used - EER and SEER.
