1. What is a kW to Tons Calculator?

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

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Tons} \) — Tons of refrigeration (1 ton = 12,000 BTU/hr)
• \( P_{\text{kW}} \) — Power in kilowatts (kW)

Explanation: The conversion factor 3.517 comes from the relationship between kW and tons (1 ton = 3.517 kW).

3. Importance of Capacity Conversion

Details: Proper unit conversion ensures accurate equipment sizing, system design, and performance comparisons in HVAC applications.

4. Using the Calculator

Tips: Simply enter the AC capacity in kilowatts (kW) and the calculator will provide the equivalent in tons of refrigeration.

5. Frequently Asked Questions (FAQ)

Q1: What is a ton of refrigeration?
A: A ton of refrigeration is a unit of power equal to the heat absorbed by melting 1 ton of ice in 24 hours (12,000 BTU/hr or 3.517 kW).

Q2: Why convert kW to tons?
A: Tons is a common unit in the HVAC industry, especially in North America, while kW is more common in other regions and scientific contexts.

Q3: Is 3.517 the exact conversion factor?
A: Yes, it's the precise conversion (12,000 BTU/hr ÷ 3412.142 BTU/hr per kW = 3.517 kW per ton).

Q4: Can I convert tons back to kW?
A: Yes, multiply tons by 3.517 to get kW (kW = Tons × 3.517).

Q5: What's a typical residential AC capacity?
A: Most homes have systems between 1.5 to 5 tons (5.3 to 17.6 kW) depending on size and climate.
