After the load is known, the HVAC designer will be able to choose the proper HVAC equipment. This step is often neglected. The most important aspect of selection is to interpret the capacity to remove heat and moisture, the total air and at what pressure the system can produce. This requires interpolation of the manufacturer’s data. Ignoring this often leads to incorrectly sized systems.
