Developments of a Dew Point Indirect Evaporative Air Conditioner ab 71.9 EURO creating environmental-friendly cooling for buildings
The book covers brief introduction and concepts about the conventional air conditioning and evaporative cooling technologies. It presents the thermodynamic performance and relevant characteristics of direct evaporative cooling system to gain knowledge about the effects of inlet velocity of air, outdoor air temperature, cooling pad thickness and their configurations. It also explains about a developed thermodynamic model by using Logarithmic Mean Temperature Difference (LMTD) approach to predict the performance of the cooling pads. The nano-refrigerant is used in the Vapor Compression Refrigeration System (VCRS), and also in evaporative cooling combined with VCRS, then both the systems are compared. This book also helps in improving the feasibility and applicability of the developed system by decreasing the size of "evaporative cooling combined with vapour compression based air conditioning system". In this book, conventional air conditioner coupled with honeycomb cooling pads for providing better thermal comfort at a minimum operating cost in hot & dry weather is theoretically investigated.
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.
