Extending the concept of energy delivery efficiency (EDE) of HVAC systems Conference Paper uri icon


  • An energy standard based on a two-zone model may still be an unrealistic standard when comparing the energy delivery efficiency (EDE) of actual heating, ventilation and air conditioning (HVAC) systems. This argument has a parallel in thermodynamics where the efficiency of an actual steam power plant is more realistically compared with the Rankine efficiency rather than with the Carnot efficiency. An HVAC configuration is suggested that ensures the stipulated ventilation airflow rates, necessary for satisfactory indoor air quality (IAQ), to each of the multiple zones of the building. The operation and control of such an ideal HVAC system is defined.
