Cooling Load Calculator for HVAC Systems (Simple Method)
The Cooling Load Calculator helps HVAC engineers and designers estimate the cooling capacity required for a room or space. Cooling load calculation is essential for selecting the correct air conditioner or HVAC equipment size.
Cooling Load Calculator
Cooling Load Formula (Simple Method)
Cooling Load (W) = Room Area × 150 + Occupants × 120
This simplified method is suitable for preliminary HVAC design and quick capacity estimation. Detailed projects should use full heat load calculations.
Example Cooling Load Calculation
- Room area = 50 m²
- Occupants = 5
- Cooling load = (50 × 150) + (5 × 120)
- Total = 8.1 kW
Where Cooling Load Calculation Is Used
- Air conditioner selection
- HVAC system sizing
- Commercial building design
- Residential cooling estimation
