    This paper presents the experimental effect of the ambient conditions (relative humidity and temperature), air mass flow and operating time on the thermal performance of direct evaporative cooler (DEC). The set up is installed in Biskra region (34°47’N - 005°43’E) characterized by semi-arid and hot climate. The results showed that the efficiency decreases with increasing the air mass flows for eight hours of continuous functioning when the air mass flow ranged between 0.165 and 0.386 kg/s, and a reduction of the experimental heat exchange rate with decreasing of the ambient temperature and increasing ambient relative humidity.
