Analysis of desiccant air-conditioning system with dew-point evaporative cooling

In this thesis, a Maisotsenko cycle based air-conditioning system supported by a desiccant wheel, heat recovery units (recuperators) and a direct evaporative cooler is investigated during a complete cooling season for air-conditioning of a school building located in Adana, Turkey. After modelling the air-conditioning system, hourly analysis for 21st day of each month during cooling season was carried out with a computer program developed. The optimum values of operational parameters, the temperature of the air inside the building and mixing ratio of the exhaust air with supply air are obtained. The effectiveness of desiccant wheel and Maisotsenko cycle, which are the two important components of the system, thermal energy requirement to run the system and cooling performance of the system are investigated in detail. The results show that it is possible to obtain comfort conditions within the building during complete cooling season with the air-conditioning system considered
