Refrigeration Tonnage Calculator
Calculate refrigeration tonnage, BTU requirements, and cooling capacity for your space. Get precise AC sizing and energy estimates for any room or building.
Step 1: Space Dimensions
Space Measurements
Accurate room dimensions are crucial for calculating proper refrigeration tonnage. Measure length, width, and height to determine total cubic volume.
Step 2: Cooling Requirements
About Refrigeration Tonnage
One ton of refrigeration equals 12,000 BTU/hr. Proper sizing prevents overworking your system and ensures energy efficiency. Oversized units cycle frequently, reducing efficiency.

Sizing Recommendations
For optimal efficiency, select a unit within 0.5 tons of calculated requirement. Oversized units cycle frequently, reducing efficiency and increasing wear. Undersized units run continuously, struggling to maintain temperature.
Energy Consumption & Cost Breakdown
Tonnage Calculation Formula
Total Tons = (Volume × ΔT × Insulation Factor + Occupancy + Equipment Load) / 12,000
Calculate room volume in cubic feet. Multiply by temperature difference and insulation factor. Add occupancy and equipment heat loads. Divide by 12,000 BTU/ton to determine required tonnage.
