AC Tonnage Formula:
| From: | To: |
AC tonnage calculation helps determine the appropriate air conditioning capacity needed for a space. In India's climate, proper tonnage calculation is crucial for energy efficiency and optimal cooling performance.
The calculator uses the simple conversion formula:
Where:
Explanation: One ton of refrigeration equals 12,000 BTU per hour, which represents the amount of heat required to melt one ton of ice in 24 hours.
Details: Proper AC tonnage calculation is essential for India's hot and humid climate. An undersized AC will struggle to cool, while an oversized AC will cycle frequently, wasting energy and not dehumidifying properly.
Tips: Enter the BTU value of your air conditioner. For Indian homes, typical room sizes require 0.8-2.0 tons depending on room size, insulation, sunlight exposure, and number of occupants.
Q1: What is the typical tonnage required for Indian rooms?
A: For a 100-150 sq ft room: 0.8-1 ton, 150-250 sq ft: 1-1.5 tons, 250-400 sq ft: 1.5-2 tons, adjusted for factors like sunlight exposure and occupancy.
Q2: Why is proper tonnage important for energy efficiency?
A: Correctly sized AC units run optimally, consume less electricity, provide better cooling, and have longer lifespan in India's demanding climate conditions.
Q3: How does India's climate affect AC tonnage requirements?
A: India's high temperatures and humidity levels require slightly higher tonnage compared to temperate climates for the same room size.
Q4: What factors besides room size affect tonnage requirements?
A: Sunlight exposure, number of windows, insulation quality, number of occupants, heat-generating appliances, and ceiling height all influence the required tonnage.
Q5: Can I use this calculator for commercial spaces?
A: While the basic conversion remains the same, commercial spaces require professional load calculation considering additional factors like occupancy density and equipment heat load.
