1. What is an Aircon HP per Room Size Calculator?

Definition: This calculator estimates the required air conditioner horsepower based on room size and the unit's efficiency (COP).

Purpose: It helps homeowners and HVAC professionals determine the appropriate air conditioning capacity for a given room 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 in square feet
\( COP \) — Coefficient of Performance (efficiency factor)

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

3. Importance of Proper Aircon Sizing

Details: Correct horsepower calculation 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 COP value (default 3.5 for standard units). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical COP value?
A: Standard air conditioners have COP between 3.0-4.0, while high-efficiency units may reach 5.0 or higher.

Q2: How does room height affect the calculation?
A: This calculator assumes standard 8-9 ft ceilings. For higher ceilings, increase the room area proportionally.

Q3: What other factors should I consider?
A: Consider window area, insulation quality, sunlight exposure, and heat-generating appliances in the room.

Q4: What if my room has special conditions?
A: For kitchens, server rooms, or sunrooms, consider adding 20-30% to the calculated HP.

Q5: How do I convert HP to BTU?
A: Multiply HP by 9,000 BTU (1 HP ≈ 9,000 BTU/hr cooling capacity).
