Abstract
The research presents a simulation model of a hybrid cooling and passive ventilation system by using the ANSYS FLUENT 19.2 program. The system consists of two floors, each floor contains a room of 1 m3 connected to a vertical solar chimney 3 m long towards the south, Each room is connected to a northward evaporative cooler with a volume of 0.054 m3. The air entering the evaporative cooler comes from the earth air heat exchanger with a length of 17 m and a depth of 3 m under the soil. The solar chimney represents the passive ventilation system, while the earth air heat exchanger and the evaporative cooler represent the hybrid cooling system. The model is simulated for the climatic conditions of the city of Kut, Iraq. In this study, we will study the effect of several factors (ambient temperature, relative humidity, solar radiation intensity, soil temperature and ventilation). The results showed that the use of this system reduces the average temperature inside the rooms by 10–15 °C and maximum ventilation rate (ACH) was 13.8 and the relative humidity increased by 20% compared to the surrounding relative humidity.
