AC Ton Calculation Formula:
| From: | To: |
AC ton calculation determines the appropriate air conditioning capacity needed for a room based on its square footage. One ton of cooling equals 12,000 BTU per hour, which is the amount of heat required to melt one ton of ice in 24 hours.
The calculator uses the standard formula:
Where:
Explanation: The formula calculates the required cooling capacity in tons based on room area, using a standard estimate of 25 BTU per square foot.
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 short-cycle, leading to humidity problems and higher energy costs.
Tips: Enter the square footage of the room you want to cool. The calculator will determine the recommended AC tonnage. Consider additional factors like ceiling height, insulation, sun exposure, and number of occupants for more precise sizing.
Q1: What if my room has high ceilings?
A: For rooms with ceilings higher than 8 feet, multiply the square footage by the ceiling height factor (ceiling height/8) before calculating.
Q2: How does insulation affect AC sizing?
A: Well-insulated rooms may require less cooling capacity, while poorly insulated rooms may need more. Adjust the BTU factor accordingly (20-30 BTU per sq ft range).
Q3: What about rooms with lots of windows or sun exposure?
A: Add 10-20% more cooling capacity for rooms with significant sun exposure or large window areas.
Q4: How many square feet does 1 ton AC cool?
A: Typically, 1 ton of cooling capacity serves 400-600 square feet, depending on climate and insulation quality.
Q5: Should I round up or down when choosing AC size?
A: It's generally better to choose the next available size if your calculation falls between standard unit sizes, but consult with an HVAC professional for specific recommendations.
