1. What is an AC Tonnage to kW Calculator?

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 equals 3.517 kilowatts of cooling power.

3. Importance of AC Tonnage to kW Conversion

Details: Understanding this conversion is essential for system sizing, energy calculations, and comparing different HVAC systems.

4. Using the Calculator

Tips: Simply enter the AC tonnage value to get the equivalent power in kilowatts. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a "ton" in AC terminology?
A: One ton of refrigeration equals the cooling power 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 standard conversion factor based on the definition of a ton of refrigeration (12,000 BTU/hr = 3.517 kW).

Q3: Is this conversion exact?
A: Yes, the conversion factor is mathematically exact, though actual system performance may vary based on efficiency.

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: Does this account for system efficiency?
A: No, this is a direct unit conversion. For actual power consumption, you would need to consider the system's COP or EER.
