1. What is the AC Tonnage Per Square Foot Calculation?

The AC Tonnage Per Square Foot calculation determines the required cooling capacity in tons based on the area to be cooled and the BTU factor per square foot. This helps in selecting the appropriately sized air conditioning unit for a given space.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Ton = \frac{Area \times Factor}{12000} \]

Where:

\( Area \) — Area in square feet (sq ft)
\( Factor \) — BTU per square foot (typically 20-30 BTU/sq ft)
12000 — Conversion factor (1 ton of cooling = 12000 BTU/hour)

Explanation: The formula calculates the required cooling tonnage by multiplying the area by the BTU factor per square foot, then converting BTU to tons by dividing by 12000.

3. Importance of Tonnage Calculation

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

4. Using the Calculator

Tips: Enter area in square feet and BTU factor (typically 20-30 BTU/sq ft depending on climate, insulation, and room usage). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical BTU factor per square foot?
A: Typically 20-30 BTU/sq ft, but varies based on climate, insulation, windows, and room usage (e.g., kitchens may need more).

Q2: Why divide by 12000?
A: Because 1 ton of cooling equals 12000 BTU per hour, converting BTU requirements to tons.

Q3: What if my space has high ceilings?
A: For high ceilings, calculate volume (cubic feet) rather than area, and use BTU per cubic foot factors instead.

Q4: Should I consider other factors beyond area?
A: Yes, consider insulation quality, window area, sun exposure, number of occupants, and heat-generating appliances for accurate sizing.

Q5: What's the consequence of wrong tonnage?
A: Undersized AC runs constantly but doesn't cool properly. Oversized AC cools quickly but doesn't run long enough to dehumidify, leading to damp, uncomfortable conditions.
