1. What is AC Tonnage to kW Conversion?

The AC tonnage to kW conversion calculates the electrical power (in kilowatts) required to produce a certain cooling capacity (measured in tons). One ton of cooling equals 3.51685 kilowatts.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( kW \) — Kilowatts (electrical power)
• \( \text{tonnage} \) — Cooling capacity in tons
• \( 3.51685 \) — Conversion factor (1 ton = 3.51685 kW)

Explanation: The conversion factor comes from the definition of a ton of refrigeration, which is the heat energy needed to melt one ton of ice in 24 hours.

3. Importance of the Conversion

Details: This conversion is essential for HVAC professionals to properly size air conditioning systems, calculate energy requirements, and estimate operating costs.

4. Using the Calculator

Tips: Enter the tonnage value in tons (1 ton = 12,000 BTU/hr). The calculator will automatically compute the equivalent power in kilowatts.

5. Frequently Asked Questions (FAQ)

Q1: Why is cooling capacity measured in tons?
A: The term originates from the amount of heat needed to melt one ton of ice in 24 hours, which equals 12,000 BTU per hour.

Q2: What's the difference between kW and tons?
A: Tons measure cooling capacity (heat removal), while kW measures electrical power input. The conversion relates these two different measurements.

Q3: How accurate is this conversion?
A: The conversion factor is mathematically exact, but real-world systems may have different efficiencies affecting actual power requirements.

Q4: Can this be used for heating systems?
A: No, this specific conversion is only for cooling capacity. Heating systems use different measurements and calculations.

Q5: What's a typical tonnage for residential AC?
A: Most homes use 1.5 to 5 tons of cooling capacity, depending on size, insulation, and climate.
