Abstract
This paper presents the conversion speed drive of the cooling tower fans from constant to variable speed. The speed of fan is adjusted using variable speed drives. Since the ambient temperature of cooling tower is varied seasonally, an economic evaluation was performed to determine the potential annual savings. The performances of the proposed technique were observed using cooling tower fans of chemical plant in Thailand as an illustrative case study. The experimental results demonstrating the energy savings fork cooling process and some economic benefits are obtained.
