Cooling Tower Tons.
[Pl. read below:
# Chiller Refrigeration Tons:
A chiller refrigeration ton is defined as:
1 refrigeration ton = 12,000 Btu/h = 3,025.9 k Calories/h
A ton is the amount of heat removed by an air conditioning system that would melt 1 ton of ice in 24 hours.
Cooling Tower Tons :
A cooling tower ton is defined as:
1 cooling tower ton = 15,000 Btu/h = 3,782 k Calories/h]
[HVAC use of a cooling tower pairs the cooling tower with a water-cooled chiller or water-cooled condenser. A ton of air-conditioning is the rejection of 12,000 Btu/hour (12,661 kJ/hour). The equivalent ton on the cooling tower side actually rejects about 15,000 Btu/hour (15,826 kJ/hour) due to the heat-equivalent of the energy needed to drive the chiller's compressor. This equivalent ton is defined as the heat rejection in cooling 3 U.S. gallons/minute (1,500 pound/hour) of water 10°F, which amounts to 15,000 Btu/hour, or a chiller coefficient-of-performance (COP) of 4.0. This COP is equivalent to an energy efficiency ratio (EER) of 13.65.]
Domestic and commercial refrigerators may be rated in kJ/s, or Btu/h of cooling.
Commercial refrigerators in the US are mostly rated in tons of refrigeration, but elsewhere in kW.
-One ton of refrigeration capacity can freeze one short ton of water at 0 °C (32 °F) in 24 hours.
