![]() This equivalent ton is defined as the heat rejection in cooling 3 U.S. The equivalent ton on the cooling tower side actually rejects about 15000 Btu/h due to the heat-equivalent of the energy needed to drive the chiller's compressor. ![]() = 12000 Btu/hr Converting between Btu/h and Tons of Refrigeration Btu/hġ cooling tower ton = 1 TONS evap = 1 TONS cond x 1.25 = 15000 Btu/h = 3782 k Calories/h = 15826 kJ/h = 4.396 kW The heat required to melt 1 lb of ice at 32 oF to water is 144 Btu.ġ Ton Refrigeration = (2000 lb) (144 Btu/lb) / (24 hr) Some commercial and industrial refrigeration systems are rated in Tons of Refrigeration (TR, tons).Ī water-chiller refrigeration ton is defined as:ġ Refrigeration Ton (RT) = 1 TONS cond = 12000 Btu/h = 200 Btu/min = 3025.9 k Calories/h = 12661 kJ/h = 3.517 kWĪ ton is the amount of heat removed by an air conditioning system that would melt 1 ton (2000 lbs.) of ice in 24 hours. For commercial and industrial refrigeration systems most of the world uses the kilowatt (kW) as the basic unit of refrigeration. The process of cooling is called refrigeration. ![]() Cooling towers tons pairs the water-cooled chiller tons and the water-cooled condenser tons.
