1. What is an Aircon HP per Sqm 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 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 3.0-4.0 for modern units)

Explanation: The formula converts cooling requirements (based on room size) to horsepower while accounting for the aircon unit's efficiency.

3. Importance of Proper Aircon Sizing

Details: Correct HP calculation ensures energy efficiency, proper cooling, and prevents short cycling or insufficient cooling capacity.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is COP in air conditioning?
A: COP (Coefficient of Performance) measures cooling efficiency - higher values mean more efficient units.

Q2: What's a typical COP value?
A: Standard units range 3.0-3.5, while high-efficiency units can reach 4.0 or more.

Q3: How does room size affect HP requirements?
A: Larger rooms require more cooling capacity, but the relationship isn't strictly linear due to other factors.

Q4: Should I round up the calculated HP?
A: Yes, it's recommended to round up to the nearest standard unit size (0.5HP, 1HP, 1.5HP, etc.).

Q5: What other factors affect aircon sizing?
A: Consider insulation, ceiling height, window area, sunlight exposure, and heat-producing appliances.
