What is the Unit of Refrigeration?

Tonne of refrigeration in short TR.

1 TR = 3.5 KW

Let’s understand, how is it possible?

1 TR = 1000 X 335 KJ in 24 hours

= 1000 X 335/(24 X 60 X 60) = 3.5 kJ/s or kW

1 tonne = 1000 Kg

Latent heat of ice = 335 kJ/kg

Definition of 1 Tonne of Refrigeration?

1 tonne of refrigeration is defined as the amount of heat, which is needed to extracts from 1 tonne of water at 0 degree C in order to convert it into equivalent ice at 0 degree C in 24 hours.

1 TR= 3.5 KW = 50 KCal./min = 210 KJ/min = 200 Btu/min = 3024 kcal/hr

Different type of unit of refrigeration system used in different country, in India TR is used as unit of refrigeration.

There is little different tonne and ton but most of the time we consider ton as 1000 in Indian examination system.
