Tiivistelmä
The subject of this thesis is the indirect adiabatic cooling. The application of such technology makes it possible to reduce the use of expensive and energy-intensive refrigerators. In addition indirect adiabatic cooling is energy efficient and profit-proved. Also it decreases the emission of fluorine-chloride refrigerants, which are charged by cooling units.
Chapter 2 gives the definition of the indirect adiabatic cooling and tells about its development. Also it describes the air-conditioner Type 55/56 Adsolair by Menerga with adiabatic cooling.
Chapter 3 familiarizes with factors influencing on the efficiency of the indirect adiabatic cooling: humidification and heat transfer. It briefly describes some different types of humidifiers and heat exchangers.
Chapter 4 describes initial data for simulation and calculation methods that is used by Fläkt Woods’ selection tool Acon.
Chapter 5 presents results and the analysis of indirect adiabatic cooling simulation that was made with computer-aided selection program Acon.
Chapter 6 discusses the results of indirect adiabatic cooling simulation in different climate. The advantages and disadvantages of this system are described in comparison to compressor cooling. Also the recommendations and ways to improvements are pointed.
