1. What is Aircon Computation per Sqm?

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

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:

\[ HP = \frac{A_{room} \times 44.6}{2545 \times COP} \]

Where:

\( HP \) — Required horsepower
\( A_{room} \) — Room area in square meters
\( COP \) — Coefficient of Performance (typically 2.5-4.0 for modern units)
44.6 — Conversion factor (W/m² to BTU/hr)
2545 — Conversion factor (BTU/hr to HP)

Explanation: The formula converts room area to cooling requirements and then to horsepower based on the unit's efficiency.

3. Importance of Proper Aircon Sizing

Details: Correct sizing ensures energy efficiency, proper cooling, and prevents short cycling which can reduce equipment lifespan.

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 COP?
A: Coefficient of Performance measures aircon efficiency - higher values mean more efficient units (typically 2.5-4.0).

Q2: How do I find my aircon's COP?
A: Check the manufacturer's specifications or energy guide label (EER divided by 3.412 gives COP).

Q3: What if my room has special conditions?
A: For rooms with high heat loads (sun exposure, many occupants), consider adding 10-20% to the calculated HP.

Q4: Is this for residential or commercial use?
A: This calculation works for both, but commercial spaces may need additional factors considered.

Q5: How does this relate to BTU ratings?
A: 1 HP ≈ 9000 BTU/hr. You can multiply the result by 9000 to get approximate BTU requirements.
