89-13: Recent Developments in the Operation of Industrial Cooling Tower SystemsThis paper is based on 6 7 years of field experience with zero blowdown systems. Steps for achieving higher tower rate cycles and monitoring systems results are explained. Multiple case histories covering the following cooling tower waters are included: 1) Unsoftened surface or well water makeup, 2) Partially softened makeup water, and 3) 100% softened makeup water without pH control. The remarkable results obtained with all of these makeup waters are

it seemed quite natural to discuss the air conditioning of our offices

The fouling of surfaces can reduce heat transfer and cooling efficiencies

The benefits of proper control are measurable and translate to improved system efficiency and reliability

but these devices are not an unmixed blessing

A creative combination of electrochemical water treatment and chemicals was employed

important for high-density urban environments

Three separate 50 days research studies using ammonia and phenol stripped coal gasification condensate from the Great Plains Coal Gasification Plant were performed

designing an optimum efficiency fan has become very valuable

In the summer of 2012

Several erosion mitigation methods are described based on CFD results
