AC Tonnage Formula:
From: | To: |
AC tonnage calculation determines the appropriate air conditioning capacity needed for a room based on its area. Proper sizing ensures efficient cooling, energy savings, and optimal performance.
The calculator uses the AC tonnage formula:
Where:
Explanation: This formula converts room area from square meters to square feet, applies standard cooling load requirements, and converts the result to AC tonnage.
Details: Correct AC sizing is crucial for energy efficiency, comfort, and equipment longevity. Undersized units struggle to cool, while oversized units short-cycle, wasting energy and reducing dehumidification.
Tips: Enter the room area in square meters. Ensure accurate measurements for best results. Consider additional factors like ceiling height, insulation, and sun exposure for precise sizing.
Q1: Why is AC tonnage important?
A: Proper tonnage ensures efficient cooling, lower energy bills, and prevents equipment strain from over or under-sizing.
Q2: What is a standard cooling load factor?
A: 25 BTU per square foot is a common estimate, but this may vary based on climate, insulation, and room usage.
Q3: How accurate is this calculation?
A: This provides a basic estimate. Professional HVAC calculations consider additional factors like windows, insulation, and occupancy.
Q4: What if my room has high ceilings?
A: For rooms with ceilings higher than 8 feet, increase the calculated tonnage by 10-20% to account for additional volume.
Q5: Can I use this for multiple rooms?
A: This calculator is designed for single rooms. For whole-house calculations, sum individual room areas or consult an HVAC professional.
