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.

Definition: A ton of refrigeration (TR) is a unit of power. It is defined as the power required to melt or freeze 2000 pounds, also known as one short ton, of ice per day. The ton is more often a unit of mass. A ton of refrigeration is approximately equal to 12,000 BTU/h or 3.5 kW.

TR to kW Conversion. The abbreviation for TR and kW is ton (refrigeration) and kilowatt respectively. 1 TR is 4 times bigger than a kW.

1. What is TR (Tons of Refrigeration) in HVAC? Answer: TR, or Tons of Refrigeration, is a measure of the cooling capacity of an HVAC system. One ton of refrigeration is equivalent to the absorption of heat at a rate of 12,000 BTU per hour. This measurement helps to quantify how much heat the system can remove from a space in one hour.

In English terminology, 1 TR is 3024 KCal. Learn How the value of 3024 KCal or 3.517 KW derived.....!! The latent heat of ice (also the heat of fusion) = 333.55 kJ/kg = 144 Btu/lb

TR to Btu/h Conversion. The abbreviation for TR and Btu/h is ton (refrigeration) and btu (it) per hour respectively. 1 TR is 12000 times bigger than a Btu/h.

2025年1月12日 · A ton of refrigeration (TR), also called a refrigeration ton (RT), is a unit of power used, especially 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 melting of 1 ton of pure ice at 0°C in 24 hours.

2024年10月27日 · It suggests that to effectively remove one ton of heat (1 TR), an HVAC system should be able to move approximately 400 cubic feet of air per minute (400 CFM).
