Abstract

A desert cooler typically is a blower fan that sucks air through a moistened surface to achieve a drop in inlet air temperature. A pump is used to circulate water from a lower tank to the evaporative pads working with a swing louver motor for directing the air automatically. The power consumption of the evaporative air cooler is primarily in single phase induction motor (SPIM) used for fan motor [1, 2]. To lower this power consumption, a brushless DC machine and its circuitry were designed and used. This is powered also by PV panel and batteries. The power consumption comparative study was carried out on SPIM and BLDC machines at three speeds. The outcome of the study shows 39.3% of power saved on with BLDC machine air coolers .
