Performance Comparison between Selected Evaporative Air Coolers

Energy Saving in Evaporative Coolers using Permanent Magnet Brushless Motors

Due to low cost, evaporative coolers are used in most of the central regions and in the warm and dry climate of Iran and are considered as one of the major consumers of electrical power. Most evaporative coolers use single-phase induction motors by connecting directly to the power grid. But their eefficiency is very low, and their replacement with high efficiency electric motors is considered b...

An Investigation of Indirect Evaporative Coolers, IEC With Respect to Thermal Comfort Criteria

Laboratory study of the impact of evaporative coolers on indoor PM concentrations

Evaporative cooling is used extensively in low humidity areas of the Southwest United States desert region and throughout other dry climate areas worldwide for residential thermal comfort. A literature review suggested the possibility of evaporative cooling increasing personal exposures to particulate matter along with increased incidences of respiratory illnesses. Indoor and outdoor particulat...

Selected Pre-Flight Expectations in the Air Transportation Industry-A Comparison Between South Africa and Malaysia

Most studies investigating passenger’s expectations of the airline transportation industry focuses on service quality and satisfaction relating to only the airline industry. This paper deals with an overview of travellers’ expectations of personal activities as part of their airline transportation experience. These aspects refer to expectations of South African and Malaysian travellers when at ...

Effect of Using Evaporative Condenser Instead of Air Condenser in Window-air Conditioners

In this paper, the application of evaporative cooling for refrigeration cycle to reduce power consumption in hot climates is emphasized. Experimental and analytical investigations were performed in order to specify the effect of evaporative cooling condenser instead of the commonly used air cooling condenser in window-air-conditioners. Evaporative condenser can reject more heat, thereby preve...
