In the present study, the results of performance analysis of a
direct-indirect hybrid evaporative cooling system have been
discussed. A cooling tower and Cooling Coil Unit (CCU)
provide the necessary pre-cooling effects, enabling a Direct
Evaporative Cooler (DEC) that cools the air even below its
wet-bulb temperature. The hybrid cooling system includes a
counter-flow wet cooling tower, a cooling coil unit and a
direct evaporative cooler. In the present paper, the amount of
saturation effectiveness in different weather conditions and
also different cooling tower ranges is investigated. Simulation
results revealed that the combination of CCU and DEC system
could provide comfort condition whereas DEC alone did not.
Based on the simulation results the cooling effectiveness of a
hybrid system is more than 100%. Thus, the investigated
hybrid system could decrease the air temperature below the
ambient wet-bulb temperature. Moreover, a case study for Iran
is done to check out the feasibility usage of the hybrid cooling
system in selected cities. All the studies aspects of the
investigated hybrid system are compared to a stand-alone
DEC. This environmentally clean and energy efficient system
can be considered as an alternative to the mechanical vapor
compression systems.
