IMPROVING THE POWER EFFICIENCY OF A LOCALLY FABRICATED COOLING SYSTEM FOR LARGE HALLS
Authors: Izevbokun A, *Olaye E
This paper presents an alternative way of improving the power efficiency of a cooling system for large halls. A prototype system was developed that utilizes a combination of direct evaporative air cooling and displacement ventilation system. This system strategically uses the application of water on a cooling pad to absorb latent heat from the air space and thus reduce temperature. The system was automated with a microcontroller based device to improve power efficiency for optimal cooling. The efficiency of the system was determined with respect to the weather condition and season times. An average cooling efficiency of 52.9% was attained using 142W of power for a hall of 30 ft × 76 ft × 12 ft.
