1. What is Aircon Horsepower per Sqm Calculator?

Definition: This calculator estimates the required air conditioning horsepower based on room area and the unit's coefficient of performance.

Purpose: It helps determine the appropriate air conditioner size for a given space to ensure efficient cooling.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( HP \) — Required horsepower
• \( A_{room} \) — Room area in square meters
• \( COP \) — Coefficient of Performance (typically 3.5 for modern units)

Explanation: The formula converts cooling requirements (44.6 BTU/hr per m²) to horsepower while accounting for unit efficiency.

3. Importance of Proper Aircon Sizing

Details: Correctly sized air conditioners operate more efficiently, provide better comfort, and have longer lifespans.

4. Using the Calculator

Tips: Enter the room area in square meters and the COP (default 3.5). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is COP?
A: Coefficient of Performance measures aircon efficiency - higher values mean more efficient units.

Q2: What's a typical COP value?
A: Modern units range from 3.0-4.0. Check your aircon specifications for exact values.

Q3: Why 44.6 BTU/hr per m²?
A: This is a standard cooling load estimate for residential spaces in moderate climates.

Q4: Should I round up the result?
A: Yes, aircon units come in standard sizes (0.5HP, 1HP, 1.5HP, etc.) - round up to nearest available size.

Q5: What factors might require adjustment?
A: High ceilings, sun exposure, or poor insulation may require increasing the calculated HP by 10-20%.
