The Office Air Handling Unit versus the Two Dedicated Air Handling Unit System
Abstract
Both analytical and the numerical methods have
been developed to compares the energy performance
of the OAHU systems and the two-AHU (TAHU)
system. The OAHU system saves up to 1.85
kilojoules heating energy for each kilogram air
supplied to the building, or 0.8 Btu for each pound air
supplied to the building when the outside air dew
point temperature is less than the room dew point
temperature. When the outside air dew point
temperature is higher than the room dew point
temperature, the OAHU system saves up to 4.65
kilojoules heating and cooling energy for each
kilogram air supplied to the building, or 2 Btu for
each pound air supplied to the building. Both OAHU
and TAHU consume the same amount of fan energy.
The paper presents the system models, the simulation
procedures and the simulation results.
