1. What is AC Capacity Calculation?

AC capacity calculation determines the appropriate air conditioning unit size in tons for a given room area. Proper sizing ensures efficient cooling, energy savings, and optimal performance.

2. How Does the Calculator Work?

The calculator uses the AC capacity formula:

Where:

• \( T \) — AC capacity in tons
• \( A \) — Room area in square feet
• 25 — BTU per square foot factor
• 12000 — Conversion factor (BTU to tons)

Explanation: The formula calculates the required cooling capacity based on room area, converting BTU requirements to tons of cooling capacity.

3. Importance of AC Capacity Calculation

Details: Proper AC sizing is crucial for energy efficiency, comfort, and system longevity. Undersized units struggle to cool, while oversized units short-cycle and waste energy.

4. Using the Calculator

Tips: Enter the room area in square feet. Ensure accurate measurements for proper AC capacity calculation. Consider additional factors like ceiling height, insulation, and sun exposure for precise sizing.

5. Frequently Asked Questions (FAQ)

Q1: Why is 25 BTU per square foot used?
A: This is a standard estimate for average rooms with 8-foot ceilings, normal insulation, and moderate sun exposure.

Q2: What if my room has high ceilings?
A: For higher ceilings, increase the area calculation or add 10-20% to the final capacity to account for additional volume.

Q3: How does room orientation affect AC capacity?
A: South-facing rooms with more sun exposure may require 10-15% more capacity, while north-facing rooms may need less.

Q4: What about rooms with many windows?
A: Add 1000 BTU for each window, especially if they receive direct sunlight, as windows contribute significantly to heat gain.

Q5: Is this calculation suitable for commercial spaces?
A: This formula is primarily for residential rooms. Commercial spaces require more complex calculations considering occupancy, equipment, and ventilation.
