1. What is a 1.5 Ton AC to kW Calculator?

Definition: This calculator converts air conditioning capacity from tons to kilowatts (kW) using a standard conversion factor.

Purpose: It helps HVAC professionals and homeowners understand the power requirements of air conditioning systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Power in kilowatts
• \( \text{Tonnage} \) — AC capacity in tons
• \( 3.517 \) — Conversion factor (kW per ton of refrigeration)

Explanation: The AC capacity in tons is multiplied by 3.517 kW/ton to get the equivalent power in kilowatts.

3. Importance of AC Power Conversion

Details: Understanding kW equivalent helps in sizing electrical systems, calculating energy consumption, and comparing system efficiency.

4. Using the Calculator

Tips: Enter the AC capacity in tons (default 1.5) and conversion factor (default 3.517 kW/ton). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why 3.517 kW per ton?
A: This is the standard conversion based on the heat of fusion of 1 ton of ice melting over 24 hours (12,000 BTU/hr = 3.517 kW).

Q2: Is this the actual power consumption?
A: No, this is the cooling capacity. Actual power draw depends on the system's Energy Efficiency Ratio (EER) or Coefficient of Performance (COP).

Q3: What's the difference between kW and tons?
A: Tons measure cooling capacity (heat removal), while kW measures power (energy per time). 1 ton = 3.517 kW of cooling effect.

Q4: Can I use this for other AC sizes?
A: Yes, simply enter any AC capacity in tons to get the equivalent kW cooling capacity.

Q5: How does this relate to SEER ratings?
A: SEER (Seasonal Energy Efficiency Ratio) compares cooling output to electrical input. Higher SEER means more cooling per kW of electricity.
