Volume 141, Issue 3
Abstract
Thermal analysis of a novel integrated system of a desiccant wheel, a solar collector, a heat exchanger, a ground heat exchanger, and a water spray evaporative cooler is performed for air conditioning cooling systems. The effects of the following parameters were studied: inlet air temperature , the inlet air humidity ratio , regeneration temperature , heat exchanger effectiveness , solar radiation , cooling coil unit effectiveness , and evaporative cooler effectiveness on the behavior of supplied air temperature , supplied air humidity ratio , cooling water flow rate , area of solar air collector , efficiency of solar air collector , and desiccant wheel effectiveness . The system with geothermal energy was found to be more efficient and to provide more human thermal comfort than the system without geothermal energy. This novel hybrid system significantly decreased the supplied air temperature from 10 to 19.5°C. The simulation results revealed that the novel integrated system can provide comfortable conditions.
