What is TR in chiller capacity?

TR (Tons of Refrigeration) is a unit used to measure chiller cooling capacity. 1 TR represents the amount of heat required to melt one ton of ice in 24 hours, approximately equal to 3.517 kW or 12,000 BTU/hr.

What is the cooling capacity of a chiller?

The cooling capacity of a chiller is the amount of heat it can remove from a process or space per hour. It is commonly expressed in kW, TR, or kBTU/hr and determines how effectively the chiller can maintain desired temperatures.

Is 1 TR equal to 0.8 HP?

No. TR measures cooling capacity, while HP measures motor power. There is no exact conversion. Rough estimates sometimes use 1 TR ≈ 1 HP for small chillers, but actual cooling depends on design, refrigerant, and efficiency.

How to calculate chiller TR to kW?

To convert TR to kW, use the formula: 1 TR ≈ 3.517 kW Example: A 5 TR chiller ≈ 5 × 3.517 = 17.585 kW.
