1. What is AC Tonnage to kW Conversion?

Definition: This calculator converts air conditioning tonnage (a unit of cooling capacity) to kilowatts (a unit of power).

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)
• \( \text{Tons} \) — Cooling capacity in tons of refrigeration

Explanation: One ton of refrigeration is equivalent to 3.517 kilowatts of power.

3. Importance of Tonnage to kW Conversion

Details: Understanding both units is essential for equipment specification, energy calculations, and system design in HVAC applications.

4. Using the Calculator

Tips: Simply enter the tonnage value (must be > 0) and the calculator will provide the equivalent power in kilowatts.

5. Frequently Asked Questions (FAQ)

Q1: What is a "ton" in air conditioning?
A: One ton of cooling capacity equals the heat needed to melt one ton of ice in 24 hours (12,000 BTU/hr).

Q2: Why 3.517 kW per ton?
A: This is the exact conversion factor derived from the definition of a ton of refrigeration (12,000 BTU/hr = 3.517 kW).

Q3: Is this conversion exact?
A: Yes, the 3.517 factor is mathematically exact, though real-world systems may have different efficiencies.

Q4: Can I convert kW back to tons?
A: Yes, divide kW by 3.517 to get tons (or use our kW to Tons calculator).

Q5: What's a typical tonnage for residential AC?
A: Most homes use 1.5-5 ton units, depending on size and climate (1 ton per 400-600 sq ft is a rough estimate).
