1. What is an Aircon HP per Sqm Calculator?

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

Purpose: It helps determine the appropriate air conditioning capacity needed 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:

Explanation: The formula calculates the cooling capacity needed per square meter and converts it to horsepower, adjusted by the unit's efficiency.

3. Importance of Proper Aircon Sizing

Details: Correctly sized air conditioning ensures energy efficiency, proper humidity control, and longer equipment lifespan.

4. Using the Calculator

Tips: Enter the room area in square meters and the COP (default 3.5 for modern 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 cooling per watt of energy.

Q2: What's a typical COP value?
A: Modern units range from 3.0 to 5.0, with 3.5 being a good average for calculations.

Q3: How does room insulation affect this?
A: Poor insulation may require increasing the calculated HP by 10-20% for adequate cooling.

Q4: What about room height?
A: For ceilings higher than 2.7m, multiply the area by (height/2.7) before calculation.

Q5: Does this account for heat sources?
A: No, for rooms with significant heat sources (appliances, sunlight), increase HP by 15-25%.
