Calculate sensible, latent, and total heat load for HVAC systems. Determine the Sensible Heat Ratio (SHR) for precise cooling coil sizing.
SHR is the ratio of sensible heat to total heat. It tells you how much of the cooling energy is spent lowering temperature versus removing moisture.
Higher airflow increases the total heat transfer capacity. The heat load calculation relies heavily on the mass or volume flow rate (CFM or L/s) of the air.
If you only account for sensible heat, your system won't remove enough moisture, leading to a cold but clammy and uncomfortable environment.
Yes, while typically used for commercial air handler calculations, these exact same thermodynamic principles apply to sizing residential air conditioners and heat pumps to ensure they are matched perfectly to the cooling load.
