1. What is an Aircon HP Calculator?

Definition: This calculator estimates the recommended horsepower (HP) for an air conditioning unit based on room size and efficiency factor.

Purpose: It helps homeowners and contractors select the properly sized air conditioning unit for optimal cooling performance and energy efficiency.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( HP \) — Recommended air conditioner horsepower
• \( A_{room} \) — Room area in square feet
• \( COP \) — Coefficient of Performance (efficiency factor, typically 3.5)

Explanation: The formula converts room area to cooling capacity requirements and adjusts for the air conditioner's efficiency.

3. Importance of Proper Aircon Sizing

Details: Correct HP sizing ensures efficient operation, prevents short cycling, maintains comfortable temperatures, and reduces energy costs.

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 COP in air conditioning?
A: COP (Coefficient of Performance) measures efficiency - higher values mean more cooling per energy unit. Standard units typically have COP 3-4.

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

Q3: When would I adjust the COP value?
A: Use higher COP (4-5) for inverter or high-efficiency units, lower COP (2-3) for older or less efficient models.

Q4: What if my result is between standard HP sizes?
A: Round up to the next available size (0.75HP, 1HP, 1.5HP, 2HP, etc.) for adequate cooling capacity.

Q5: Does this account for room insulation?
A: No, for poorly insulated rooms or sunny locations, consider increasing HP by 10-20%.
