1. What is an Aircon Horsepower Calculator?

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

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:

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

Where:

\( HP \) — Required aircon horsepower
\( A_{room} \) — Room area (square feet)
\( COP \) — Coefficient of performance (efficiency factor)

Explanation: The formula converts room area to BTU requirements, then calculates the necessary horsepower based on the unit's efficiency.

3. Importance of Proper Aircon Sizing

Details: Correct horsepower selection ensures energy efficiency, proper cooling, and prevents system overwork or short-cycling.

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 efficiency - higher values mean more efficient units (typically 2.5-5.0).

Q2: How do I measure my room area?
A: Multiply length by width of the room in feet. Include adjacent open spaces if not separated by doors.

Q3: What COP value should I use?
A: Standard units are ~3.5. Check your unit's specifications or use 3.5 as default if unknown.

Q4: How does room insulation affect this?
A: Poor insulation may require 10-20% more capacity. Well-insulated rooms may need less.

Q5: What about rooms with high sun exposure?
A: For south-facing rooms or those with large windows, consider adding 10-15% to the calculated HP.
