Question

One ton of refrigeration (TR) can be expressed as :

• A. 1 TR = 311 kJ/min = 5.5167 kW
• B. 1 TR = 111 kJ/min = 4.5167 kW
• C. 1 TR = 411 kJ/min = 2.5167 kW
• D. 1 TR = 211 kJ/min = 3.5167 kW

Hint:

Remember these standard conversion constants for 1 TR:
- Imperial units: \(200\ \text{Btu/min}\) or \(12000\ \text{Btu/hr}\).
- Metric units: \(50\ \text{kcal/min}\) or \(3000\ \text{kcal/hr}\).
- SI units: \(210\ \text{kJ/min}\) (or 211) or \(3.5167\ \text{kW}\).
