Design strategies for efficient HVAC systems

摘要

There are many factors to consider when choosing and designing HVAC systems for buildings. Those decisions ultimately influence how energy-efficient the building is. The major factors to optimize for energy efficiency are ventilation, zone control, heat recovery, and operations. Ventilation HVAC equipment exists to fulfill two goals: ventilation and comfort conditioning. To accomplish those two goals, a certain amount of energy has to be expended, but the goal of an efficient HVAC system is to minimize the energy input to do it. Ventilation in hot, humid, and cold climates is one of the largest loads on HVAC systems.
