A Simple Two Stage Indirect Direct Evaporative Cooling System Indirect systems with vapor compression second stages can provide adequate comfort cooling in high humidity zones with savings of up to 25%. a simple two stage idec system as shown in figure 6. 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.
Schematic Diagram Of Two Stage Indirect Direct Evaporative Cooler 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. Rasha et al. (2022) revealed that the direct evaporative cooling system produces a highly effective system where the internal humidity is high and the indirect method has lower effectiveness but constant humidity, hence the combination of the two systems will facilitate a two stage evaporative cooling system. 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. Abhishek sharma1, hemant darokar2. me (heat power) student1, assistant professor2 abtau56@gmail 1, hemantdarokar@rediffmail 2. abstract—the performance of two stage indirect direct evaporative cooling system is experimentally investigated. for this purpose, a two stage evaporative cooling experimental setup consisting of an indirect.

The results showed that the two stage direct indirect had 50% higher wet bulb effectiveness than the single stage while having the same inlet parameters. eldessouky (citation 2004) analysed the performance of a two stage direct indirect evaporative cooler using high density polythene as the filler material. results revealed that the efficiency. A simple two stage indirect direct evaporative cooling system table 4 shows a summary of the system perf ormance estimated over the 12 months for the two stage idec system.
