What is Ton of Refrigeration(T.O.R)?
The amount of heat absorbed or extracted by 1 Ton of ice to melt completely in 24 hr is called one ton of refrigeration.
Latent Heat of one kg of ice of one Kg = 336 kJ/kg
So Latent Heat of Ice of 1 ton = 336KJ/Kg x 1000 Kg = 336000 kJ
As we now understand , The Amount of heat absorbed or extracted by one ton of ice in 24 hours is called Ton of Refrigeration or Cooling Effect.So One Ton of Refrigeration = 336000 divided by 24 hours = 14000 KJ/Hr
