1. What is an AC Ton to kW Calculator?

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 (1 ton = 12,000 BTU/h)

Explanation: One ton of refrigeration equals approximately 3.517 kilowatts, based on the conversion from BTU/h to kW.

3. Importance of AC Capacity Conversion

Details: Understanding both units is crucial for equipment specification, energy calculations, and comparing system performance across different measurement standards.

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: A unit of power describing the heat extraction capacity of air conditioning equipment. 1 ton = 12,000 BTU/h (the cooling power of one ton of ice melting in 24 hours).

Q2: Why is the conversion factor 3.517?
A: It comes from converting 12,000 BTU/h to kW (1 kW ≈ 3,412 BTU/h → 12,000/3,412 ≈ 3.517).

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

Q4: Is this conversion exact?
A: It's a standard conversion, but actual system performance may vary slightly based on operating conditions.

Q5: Can I convert kW back to tons?
A: Yes, divide kW by 3.517 to get tons (or use our kW to Tons calculator).
