1. What is kW to TR Conversion?

The kW to TR conversion calculates tons of refrigeration from kilowatts. TR (tons of refrigeration) is a unit of power used in refrigeration and air conditioning to describe the heat extraction capacity, where 1 TR equals 3.51685 kW.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( TR \) — Tons of refrigeration
• \( kW \) — Kilowatts
• \( 3.51685 \) — Conversion factor (1 TR = 3.51685 kW)

Explanation: This formula converts electrical power input (kW) to refrigeration capacity output (TR) based on the standard conversion factor.

3. Importance of kW to TR Conversion

Details: This conversion is essential for HVAC engineers, technicians, and designers to properly size refrigeration systems, compare equipment performance, and ensure energy efficiency in cooling applications.

4. Using the Calculator

Tips: Enter the kilowatt value you want to convert to tons of refrigeration. The value must be a positive number greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What exactly is a ton of refrigeration?
A: One ton of refrigeration is the amount of heat required to melt one ton (2000 pounds) of ice in 24 hours, equivalent to 12,000 BTU/hour or 3.51685 kW.

Q2: Why is the conversion factor 3.51685?
A: This factor comes from the definition: 1 TR = 12,000 BTU/hour = 3.51685 kW, based on the conversion between BTU and kilowatt-hours.

Q3: Is this conversion used worldwide?
A: Yes, the TR unit is widely used in the refrigeration and air conditioning industry globally, though some regions may use kW exclusively.

Q4: What's a typical TR rating for residential AC units?
A: Residential air conditioners typically range from 1.5 to 5 TR, with larger homes requiring higher capacity units.

Q5: Can I convert TR back to kW?
A: Yes, to convert TR to kW, multiply the TR value by 3.51685 (kW = TR × 3.51685).
