1. What is an Aircon HP per Area Calculator?

Definition: This calculator estimates the required air conditioner horsepower (HP) 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:

\[ HP = \frac{A_{room} \times 139}{2545 \times COP} \]

Where:

\( HP \) — Required air conditioner horsepower
\( A_{room} \) — Room area (square feet)
\( COP \) — Coefficient of Performance (typically 3.0-4.0 for modern units)

Explanation: The formula converts room area into cooling capacity requirements while accounting for the air conditioner's efficiency.

3. Importance of Proper Aircon Sizing

Details: Correct HP 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 feet and the COP (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 (typically 3.0-4.0 for modern ACs).

Q2: How do I measure room area?
A: Multiply length by width of the room in feet. Include all connected spaces without doors.

Q3: What COP value should I use?
A: Check your AC unit specifications. Use 3.0 for older units, 3.5 for standard, or 4.0 for high-efficiency models.

Q4: What if my room has high ceilings?
A: Multiply the area by ceiling height (in feet) divided by 8 (standard height) for more accurate results.

Q5: How does this relate to BTU ratings?
A: 1 HP ≈ 9,000 BTU/hr. You can convert the result to BTUs by multiplying by 9,000.
