| Abstract | This study aims to present the fundamentals in which operation of a 100% outdoor air
system integrates with indirect and direct evaporative cooling systems and to estimate its
energy saving potential. The simulation of the proposed system is performed using a
commercial equation solver program, and the annual operation energy saving potential with
respect to a conventional variable air volume system is determined. This paper shows that
significant operation energy savings (i.e. 21?51% less energy consumption) is possible
principally by the pre-conditioning of supply air due to the waste heat recovery using the
indirect evaporative cooler and the sensible heat exchanger units. By components, the
proposed system shows a 16?25% less annual cooling coil load and an 80?87% reduced
annual heating coil load with respect to the conventional variable air volume system, while
there is no fan energy savings expected.
Practical applications: This paper provides practical insight on how the evaporative
cooling based 100% outdoor air system operates and how each essential component, such
as the indirect evaporative cooler, cooling coil, direct evaporative cooler, heating coil and
sensible heat exchanger should be controlled during the seasons for realising energy
conservation benefits. The sequence of operation presented in this paper can be
implemented to actual control logic. |
