Abstract
AbstractThermal 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 Tin,air, the inlet air humidity ratio ωin,air, regeneration temperature TReg, heat exchanger effectiveness eHE, solar radiation Gt, cooling coil unit effectiveness eECCU, and evaporative cooler effectiveness eEC on the behavior of supplied air temperature Tsup,air, supplied air humidity ratio ωsup,air, cooling water flow rate m˙w, area of solar air collector ASol, efficiency of solar air collector ηSol, and desiccant wheel effectiveness eDW. 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 re...
