In recent years, the concept of the usage of new energies for cooling and heating in buildings has attracted the attention of engineers. In this study, the combination of solar chimneys with wind catchers has been suggested to provide natural and pleasant ventilation. It explains the increased efficiency of wind catchers for cooling through the help of solar chimneys. In addition, with the use of solar energy for moving air inside the building by a solar chimney and using the hidden heat of water evaporation, for providing cooling, which is created at the top of wind catcher, we will be able to provide a pleasant environment with suitable temperature and humidity that complies with the standards of pleasant ventilation in hot and dry climates. In continuing this research, attention had been paid to this design for Kerman City, which is located in the hot and dry climate of Iran. Wet channels and walls with radiance are placed together with water injection systems in entrances. In addition, the turbulence model had been used to calculate the buoyancy forces and the radiance model for radiance. The project considers the system performance in a constant manner and the effect of certain parameters, including entrance air temperature, rate of injected water and rate of heat flow field, and temperature and relative humidity.
Key words: Renewable energies, solar building, wind catcher, solar chimney, natural ventilation, economies in fuel usage.
