1. What is Room Size for 1HP Aircon Calculator?

Definition: This calculator determines the appropriate room size (in square feet) that can be effectively cooled by a 1 HP air conditioning unit based on its COP.

Purpose: Helps homeowners and HVAC professionals properly size air conditioning units for rooms to ensure efficient cooling.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( A_{room} \) — Room area in square feet
• \( COP \) — Coefficient of Performance (typically 3.0-4.0 for residential units)
• 2545 — Conversion factor (BTU/hr per HP)
• 139 — BTU/hr per square foot cooling requirement

Explanation: The formula calculates how much area can be cooled by converting HP to BTU/hr and adjusting for the aircon's efficiency (COP).

3. Importance of Proper Room Size Calculation

Details: Correct sizing prevents energy waste (oversized units) or insufficient cooling (undersized units), and extends equipment life.

4. Using the Calculator

Tips: Enter the COP value (default 3.5 for typical residential units). The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is COP in air conditioning?
A: COP (Coefficient of Performance) measures cooling efficiency - higher values mean more efficient cooling per unit of energy.

Q2: What's a typical COP value?
A: Residential units typically have COP between 3.0-4.0. Check your unit's specifications for exact value.

Q3: Why 2545 in the formula?
A: This converts 1 HP to BTU/hr (1 HP = 2545 BTU/hr), the standard cooling capacity measurement.

Q4: What if my room has special conditions?
A: For rooms with high ceilings, lots of windows, or poor insulation, reduce the calculated area by 10-20%.

Q5: How does this relate to SEER ratings?
A: SEER = COP × 3.412. Higher SEER units will have higher COP values and can cool larger areas.
