1. What is an Aircon HP Calculator?

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

Purpose: It helps homeowners and HVAC professionals determine the appropriate air conditioner size for optimal cooling performance.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The formula converts room area into cooling capacity requirements, adjusted by the air conditioner's efficiency.

3. Importance of Proper Aircon Sizing

Details: Correct HP 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 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 cooling per energy unit (typically 3-5 for modern units).

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

Q3: What if my room has special conditions?
A: For sunny rooms, high ceilings, or kitchens, consider adding 10-20% to the calculated HP.

Q4: What's the difference between HP and BTU?
A: 1 HP ≈ 9,000 BTU/hr. This calculator converts area directly to HP for local market standards.

Q5: Can I use this for commercial spaces?
A: This is designed for residential use. Commercial spaces require additional factors like occupancy and heat-generating equipment.
