How to Convert Kilowatt to Ton of Refrigeration
- 1 kW = 0.2843451361 TR
- 1 TR = 3.516852842 kW
- Example: convert 15 kW to TR: 15 kW = 15 × 0.2843451361 TR = 4.265177041 TR
Formula
TR = kW × 0.284345136094
or TR = kW ÷ 3.516852842067
Derivation from SI units:
- 1 kW = 10³ W
- 1 TR = 12 000 BTU/h = 3516.8528420667 W
- 1 kW = 1000 W ÷ 3516.852842067 W per TR = 0.284345136094 TR
Both units are defined exactly, so the factor is exact. Kilowatt definition: kilowatt; Ton of Refrigeration definition: ton of refrigeration.
Worked examples
- A 10 kW heat pump is a 2.843451361 TR unit.
10 kW × 0.2843451361 = 2.843451361 TR - A 1000 kW chiller plant is 284.3451361 TR.
1000 kW × 0.2843451361 = 284.3451361 TR
