1. What is an Aircon per Square Meter Calculator?

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

Purpose: It helps homeowners and HVAC professionals determine the appropriate air conditioner size for a given space.

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 (typically 3.5 for modern units)

Explanation: The formula calculates the cooling capacity needed based on room size and the efficiency of the air conditioning unit.

3. Importance of Proper Aircon Sizing

Details: Correctly sized air conditioners operate more efficiently, provide better comfort, and have longer lifespans. Oversized units short-cycle, while undersized units run continuously.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

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

Q2: What's a typical COP value?
A: Modern units typically have a COP between 3.0 and 4.0. Higher values indicate more efficient units.

Q3: How does room height affect the calculation?
A: This calculator assumes standard ceiling heights. For rooms with high ceilings, multiply the result by 1.2-1.5.

Q4: What about rooms with lots of windows or poor insulation?
A: Increase the calculated HP by 10-20% for sun-facing rooms or poor insulation.

Q5: How do I convert HP to BTU/h?
A: Multiply HP by 9,000 to get approximate BTU/h (1 HP ≈ 9,000 BTU/h).
