1. What is Aircon Horsepower per Square Meter?

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

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 aircon horsepower
• \( A_{room} \) — Room area (square meters)
• \( COP \) — Coefficient of Performance (efficiency factor)
• 44.6 — Conversion factor (139 BTU/h/ft² converted to metric)
• 2545 — BTU/h per horsepower

Explanation: The formula calculates the cooling capacity needed per square meter and converts it to horsepower.

3. Importance of Proper 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 3.0 for typical units). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical COP value?
A: Modern air conditioners typically have COP values between 2.5 and 4.0, with higher values indicating better efficiency.

Q2: How does room insulation affect the calculation?
A: Poor insulation may require a larger unit. Consider increasing the calculated HP by 10-20% for poorly insulated spaces.

Q3: What about rooms with high heat loads?
A: For rooms with many windows, high ceilings, or heat-generating equipment, increase the calculated HP by 20-30%.

Q4: Can I use this for commercial spaces?
A: This calculator is designed for residential applications. Commercial spaces may require more complex calculations.

Q5: How do I find my air conditioner's COP?
A: Check the unit's specifications or Energy Guide label. It's often listed as "Energy Efficiency Ratio" (EER) or "Seasonal COP."
