AC Calculation Formula:
From: | To: |
AC tonnage calculation determines the appropriate air conditioning capacity needed for a room based on its square footage. Proper sizing ensures efficient cooling and energy consumption.
The calculator uses the AC sizing formula:
Where:
Explanation: This formula calculates the required AC tonnage based on standard cooling load estimates of 25 BTU per square foot, converted from BTU to tons.
Details: Correct AC sizing is crucial for energy efficiency, proper humidity control, and preventing short cycling. Oversized units cool too quickly without proper dehumidification, while undersized units struggle to maintain temperature.
Tips: Enter the room area in square feet. The calculator will determine the recommended AC capacity in tons. Ensure accurate room measurements for best results.
Q1: What is a "ton" in AC terminology?
A: One ton of cooling equals 12,000 BTU per hour, which represents the amount of heat needed to melt one ton of ice in 24 hours.
Q2: Is 25 BTU per square foot sufficient for all rooms?
A: This is a general guideline. Factors like ceiling height, insulation, window area, and climate may require adjustments to this factor.
Q3: What if my room has high ceilings?
A: For rooms with ceilings higher than 8 feet, multiply the area by (ceiling height ÷ 8) before using the calculator.
Q4: Should I round up or down when choosing AC capacity?
A: It's generally recommended to round up to the nearest standard AC size (1 ton, 1.5 ton, 2 ton, etc.) for optimal performance.
Q5: What other factors affect AC sizing?
A: Window orientation, insulation quality, number of occupants, heat-generating appliances, and local climate all impact the actual cooling load requirements.
