Answer to Question #231596 in Physics for Zia

Question

Express the unit of refrigeration. Find the power required to produce one ton of refrigeration.

Answer 1

A ton of refrigeration (TR or TOR), also called a refrigeration ton (RT), is a unit of power used in some countries (especially in North America) to describe the heat-extraction capacity of refrigeration and air conditioning equipment. It is defined as the rate of heat transfer that results in the freezing or melting of 1 short ton (2,000 lb; 907 kg) of pure ice at 0 °C (32 °F) in 24 hours.

A refrigeration ton is approximately equivalent to 12000 BTU/h or 3.5 kW.
