1. What is HVAC Ton to kW Conversion?

Definition: This calculator converts cooling capacity from tons of refrigeration to kilowatts (kW).

Purpose: It helps HVAC professionals and engineers convert between these common units of cooling capacity measurement.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Power in kilowatts (kW)
• \( Tons \) — Tons of refrigeration

Explanation: One ton of refrigeration equals 3.517 kilowatts of cooling power.

3. Importance of Unit Conversion

Details: Proper conversion between tons and kW ensures accurate system sizing, energy calculations, and equipment specification in HVAC design.

4. Using the Calculator

Tips: Simply enter the cooling capacity in tons of refrigeration to get the equivalent value in kilowatts.

5. Frequently Asked Questions (FAQ)

Q1: What is a ton of refrigeration?
A: One ton of refrigeration is the cooling power needed to freeze one ton (2000 lbs) of water at 0°C in 24 hours.

Q2: Why is the conversion factor 3.517?
A: This comes from the definition of 1 ton = 12,000 BTU/hr and 1 kW = 3,412 BTU/hr (12,000/3,412 ≈ 3.517).

Q3: When would I need this conversion?
A: When working with international specifications (kW is common in metric countries) or comparing equipment with different rating units.

Q4: Is this conversion exact?
A: The 3.517 factor is standard, though some sources may use 3.51685 for more precise calculations.

Q5: Can I convert kW back to tons?
A: Yes, divide kW by 3.517 to get tons (Tons = kW ÷ 3.517).
