The main thrust of this paper is to investigate the energy saving potentials of an 100% outdoor air (OA) system integrated with indirect (IEC) and direct evaporative coolers (DEC). For estimating the energy performance of the proposed system, it was assumed that four typical 60m2 classrooms were served by two different HVAC systems; the 100% outdoor air system and the conventional variable air volume (VAV) system. Transient behavior and control characteristics of each system were modeled numerically using a commercial equation solver program. Annual air conditioning and fan energy consumptions were estimated and then the energy saving potentials of the proposed 100% OA system were predicted. It was found that 100% OA system integrated with IEC and DEC would be able to reduce the annual cooling coil load about 16-25% and the annual heating coil load around 80-87% with respect to the conventional VAV system. Consequently, the overall operating energy saving potentials of the proposed system is 21-51%, while it depends highly on the effectiveness of the IEC unit. |
