Cooling Load Estimation 'link' Jun 2026

It’s essential to distinguish between (the total heat entering a space) and cooling load (the heat the HVAC system must remove). Due to thermal storage in building materials, cooling loads often peak hours after peak heat gain—a phenomenon known as thermal lag .

The is the ratio of sensible cooling load to the total cooling load. If a space has a low SHR (high latent load, such as a gym or a crowded auditorium), the air conditioning system must be selected specifically for its dehumidification capability. A standard unit sized only for temperature will leave the space feeling cold and "clammy" because it cannot remove the moisture fast enough. cooling load estimation
