1. What is the Cassette AC Coverage Calculator?

The Cassette AC Coverage Calculator estimates the approximate area that a cassette air conditioner can effectively cool based on its tonnage capacity. This helps in proper AC sizing for optimal performance and energy efficiency.

2. How Does the Calculator Work?

The calculator uses the standard rule of thumb formula:

Where:

• \( Tonnage \) — Cooling capacity in tons (1 ton = 12,000 BTU/hr)
• \( 500 \) — Standard coverage area per ton in square feet

Explanation: This formula provides a general estimate based on typical residential and commercial cooling requirements.

3. Importance of Proper AC Sizing

Details: Correct AC sizing is crucial for energy efficiency, proper humidity control, and optimal comfort. Oversized units short cycle, while undersized units struggle to maintain temperature.

4. Using the Calculator

Tips: Enter the AC tonnage (typically 1-5 tons for most applications). The calculator will estimate the approximate coverage area in square feet.

5. Frequently Asked Questions (FAQ)

Q1: Why 500 sq ft per ton?
A: This is a general rule of thumb for moderate climates. Actual requirements may vary based on insulation, ceiling height, and local climate.

Q2: What factors affect coverage area?
A: Insulation quality, window area, ceiling height, number of occupants, and local climate conditions all impact the actual coverage area.

Q3: When should I consult a professional?
A: For precise calculations, always consult with an HVAC professional who can perform a Manual J calculation for your specific space.

Q4: Are cassette ACs different from other types?
A: Cassette ACs are ceiling-mounted and provide 360-degree airflow, making them efficient for open spaces, but coverage calculations use the same principles.

Q5: What about high ceilings or poor insulation?
A: Spaces with high ceilings (>10 ft) or poor insulation may require more cooling capacity - reduce the coverage area estimate by 10-20% in such cases.
