New air cooler with low power consumption

Energy saving mechanism is the reason behind this research project that led us to design, develop and build a new evaporative air cooler unit with high efficiency and low power consumption. This was done by designing a new water distribution system that eliminated the water pump of the standard unit and modifying its mechanical parts. Also, design of an intelligent controller was added to optimize performance of the new unit. This prompted to attain lower energy consumption, longer mean time between failures, lower maintenance, and independence from the power grid. Several tests and analyses have been conducted on both the newly designed unit and the standard unit. The new design delivered air with noticeably higher humidity and lower temperature than the existing unit. The low energy consumed by newly designed unit, also led to a reduction in size of the proposed photovoltaic solar panels as a power source.
