1. What is AC Tonnage Calculation?

AC tonnage calculation determines the appropriate air conditioning capacity needed for a room based on its square footage and BTU requirements per square foot. This helps ensure efficient cooling and energy usage.

2. How Does the Calculator Work?

The calculator uses the AC tonnage formula:

\[ Ton = \frac{(Square Feet \times BTU\ per\ sq\ ft)}{12000} \]

Where:

\( Square Feet \) — Area of the room in square feet
\( BTU\ per\ sq\ ft \) — British Thermal Units required per square foot
\( 12000 \) — Conversion factor (1 ton of cooling = 12000 BTU/hour)

Explanation: The formula calculates the required cooling capacity in tons by multiplying the room area by the BTU requirement per square foot, then converting to tons.

3. Importance of Proper AC Sizing

Details: Proper AC sizing is crucial for energy efficiency, comfort, and system longevity. An undersized unit will struggle to cool the space, while an oversized unit will cycle too frequently, reducing efficiency and comfort.

4. Using the Calculator

Tips: Enter the room area in square feet and the BTU requirement per square foot. Typical BTU per sq ft values range from 20-30 for standard rooms, but may vary based on climate, insulation, and other factors.

5. Frequently Asked Questions (FAQ)

Q1: What is a refrigeration ton?
A: One ton of refrigeration equals 12,000 BTU per hour, which is the amount of heat needed to melt one ton of ice in 24 hours.

Q2: How do I determine BTU per square foot?
A: BTU requirements depend on factors like climate, insulation, window area, and room usage. Generally, 20-30 BTU per sq ft is standard for moderate climates.

Q3: What if my room has high ceilings?
A: For rooms with ceilings higher than 8 feet, multiply the square footage by the height factor (ceiling height ÷ 8) before calculating.

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

Q5: What's the consequence of incorrect AC sizing?
A: Incorrect sizing can lead to poor humidity control, higher energy bills, reduced comfort, and shorter equipment lifespan.
