Developments of a Dew Point Indirect Evaporative Air Conditioner ab 71.9 EURO creating environmental-friendly cooling for buildings
The combination of direct evaporative cooling and indirect evaporative cooling system is called indirect-direct two stage evaporative cooling. In two stage air cooler Effective temperature decreases, COP increases up to 13 which are significantly higher than normal cooler and conventional air conditioner, Refrigeration effect increases, Makeup water recharges time increases for the same configuration has been obtained, Specific humidity increase is significantly lower than that of in case of direct cooling system. Two stage air cooler is energy effective, eco friendly, cost effective cooling system and with some further modification it may be hope as replacement of air conditioner.
This book describes dedicated research aiming to improve the performance of existing indirect evaporative coolers. A new dew point indirect evaporative cooler with counter-current heat and mass exchanger was developed in this book by optimal design, material selection, numerical simulation, experimental investigations and economic, environmental, regional acceptance analysis. The research found that the dew point cooler can achieve higher performance than typical indirect evaporative coolers without adding too much cost. The cooler's effectiveness and energy efficiency were found to be largely dependent upon channel geometries, intake air velocity, temperature, humidity, and working-to-intake air ratio but less on input water temperature.
