Schematic Diagram Of Two Stage Indirect Direct Evaporative Cooler Indirect direct cooling, also known as two stage evaporative cooling, uses both indirect and direct cooling techniques to cool the air. the first indirect "cooling step" uses cold recirculation water to pre cool the ambient air in a heat exchanger. because no moisture is added, the air reaches a lower dry bulb and wet bulb temperature than the. Hybrid evaporative cooling (two stage idec) 75–90: 0.5–1.0: very low; integrates multiple cooling methods: 15–25: combines indirect and direct cooling, dual stage configuration: first stage: air is pre cooled indirectly, second stage: air is cooled directly by passing through wet media : hybrid evaporative cooling (three stage idec) 80.
Two Stage Evaporative Cooling System Indirect Direct Evaporative A two stage evaporative cooling system can deliver cool indoor air with a relative humidity in the 50% 65% range, while direct evaporative cooling systems typically condition the air at around 70% relative humidity. according to the american society of heating and engineers (ashrae), advanced two stage evaporative coolers can use 60% 75% less. The results revealed better cooling efficiency over a single stage. farmahini farahani et al. (citation 2010) constructed a two stage system consisting of an indirect evaporative cooling and nocturnal radiative cooling system using three different models. all three models performed well and provided both the necessary and required cooling. Cooling performance of two stage indirect direct evaporative cooling system is experimentally investigated in the various simulated climatic conditions. for this purpose, a two stage evaporative cooling experimental setup consisting of an indirect evaporative cooling stage (iec) followed by a direct evaporative cooling stage (dec) was designed. Abstract: space cooling has become a major source of energy use, such that, during the hot summer months, cooling. performance of two stage indirect direct evaporative cooling system is.

Abstract: space cooling has become a major source of energy use, such that, during the hot summer months, cooling. performance of two stage indirect direct evaporative cooling system is. Indirect cooling is often paired with a second direct evaporative cooling stage, to cool the supply air further while adding some moisture to the supply air. two stage systems (often referred to as indirect direct or idec systems) can meet the entire cooling load for many industrial and commercial buildings in arid to semi arid climates. Farmahini farahani and heidarinejad [26] proposed a multi step system by combining a nocturnal radiative pre cooling with a two stage indirect direct evaporative cooling. it was found that this multi step system with higher energy efficiency could replace the mechanical vapor compression system.
