1. What is an Air Con kW Calculator?

Definition: This calculator estimates the required air conditioning power in kilowatts based on room area and the system's COP.

Purpose: It helps HVAC professionals and homeowners determine the appropriate air conditioning capacity needed for a given space.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Required air conditioning power (kilowatts)
• \( A_{room} \) — Room area (square meters)
• \( COP \) — Coefficient of Performance (typically 3.0 for modern units)

Explanation: The formula converts the cooling load (44.6 BTU/hr per m²) to kW while accounting for the system's efficiency (COP).

3. Importance of Proper Sizing

Details: Correctly sized air conditioning ensures energy efficiency, proper dehumidification, and equipment longevity.

4. Using the Calculator

Tips: Enter the room area in square meters and the COP (default 3.0). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is COP in air conditioning?
A: COP (Coefficient of Performance) measures efficiency - the ratio of cooling output to energy input.

Q2: What's a typical COP value?
A: Modern units typically have COP between 3.0-4.0, but check your specific model's specifications.

Q3: Why 44.6 BTU/hr per m²?
A: This is a standard cooling load estimate for moderately sized rooms with average insulation.

Q4: Should I round up the result?
A: Yes, it's recommended to round up to the nearest standard unit size available.

Q5: Does this account for other factors?
A: This provides a baseline. Consider insulation, windows, occupancy, and heat-generating appliances for precise sizing.
