How Indirect Evaporative Cooling Works Youtube Learn how indirect evaporative coolers work without adding moisture to the air stream. see how indirect evaporative cooling is used in 4 different systems in. Direct evaporative cooling systems. in a direct evaporative cooling system outside air is pulled through a water saturated medium (typical cellulose) or air is sprayed with water and cooled by evaporation. the cooled air is circulated by a blower. moisture can be added to the air stream until saturation. dry bulb temperature is reduced.

Indirect Evaporative Cooler вђ Westaire Engineering Inc According to a nrel study the use of a multi stage indirect evaporative cooler there are “three target market segments that have been identified for this technology: data center installations in ashrae climate zones 2b through 6b; outside air pre conditioner retrofits for air cooled rtus in climate zones 2b and 3b; and new construction and facilities that do not currently have cooling. First stage : indirect cooling. as depicted below in the schematic diagram, the indirect evaporative air cooling stage cools the outdoor air without adding moisture. this cooling is typically achieved using one of two methods. in one method a cooling tower may be used to provide naturally cooled water to a cooling coil in the ahu. Than direct evaporative and vapor compression cooling systems. the primary focus of this monograph is to highlight recent developments in evaporative air cooling technologies, in particular indirect dew point evaporative cooling. the state of the art evaporative cooling technologies are first discussed, and a comprehensive review of. Air to air indirect evaporative cooling (iec) systems are particular heat exchangers that use the latent heat of evaporation of water to cool down an air stream, without increasing its specific humidity, thus guaranteeing adequate thermohygrometric conditions in the refrigerated environment with low energy consumption. dew point indirect evaporative cooling (diec) systems are based on the iec.

Fig. 2.1 working principle of direct evaporative cooling: a schematic diagram; b psychrometric chart. black “dot dash lines” represent constant relative humidity (rh) lines and red “dash lines” represent isenthalpic lines. fig. 2.2 direct evaporative cooler: a cooling pads; b typical cooler unit. The regenerative evaporative cooling system (r d iec) is an improved version of indirect evaporative cooling system, a portion of the product air is extracted at the outlet and is directed towards wet channel as the working air [20]. in this case, working air is already cooled, so the wet bulb temperature is lower than that of regular outside working air.
