Heat Load Calculation in Air Conditioning Systems
Introduction
Heat load calculation is essential in HVAC design to determine the cooling or heating requirement
for maintaining indoor comfort.
Types of Heat Load
- Sensible Heat: Temperature change without moisture change.
- Latent Heat: Heat due to moisture content.
Sources of Heat Gain
- External: Solar radiation, infiltration
- Internal: Occupants, equipment, lighting
Key Parameters
DBT, WBT, Relative Humidity, CFM, TR
Formula
Q = m × Cp × ∆T
Conclusion
Accurate calculation ensures energy efficiency and proper system sizing.
