heal.abstract	Wind catchers are one of the oldest cooling systems in Hot-Dry regions that are employed to provide sufficient natural ventilation in buildings. The optimal adequacy of the wind catchers has been constrained in the suitable wind speed, which causes them to be inefficient at times and in areas with low wind speed. A four-directional wind catcher equipped with two evaporative cooling parts (wetted blades and adjustable opening pads) and a solar chimney was proposed in this study. A prototype of the proposed wind catcher has developed to analyze the performance of the system. Theoretical analysis of the wind catcher was carried out and a set of experiments were organized to validate the results of the obtained models. Moreover, a numerical simulation investigated the ventilation performance of the solar chimney. The results showed when the pad was closed, the maximum value of cooling load was achieved at the wind speed of 3(m⁄s). In addition, at the wind catcher heights of 2.5 and 3.5 m and the wind speeds of lower than 3(m⁄s), the cooling loads approximately doubled by employing closed-pad mode. Compared with the open-pad mode, the closed-pad mode has shown better results, when the wind speed was low. The airflow rate at the no-wind condition and solar radiation of 1000 (W/m2) was eventuated around 0.021 (kg/s), if applying the evaporative cooling system. Consequently, the combined system increases the mass flow rate of the air by several times in the low wind speed compared that without the solar chimney.	en
