17-08: Design Cooling Tower System to Reduce the Risks of Transmitting Legionna Ozone

17-08: Design Cooling Tower System to Reduce the Risks of Transmitting Legionna OzoneASHRAE Standard 188 2015 established minimum legionellosis requirements for building water systems. When a building survey determines that it has an open and closed circuit cooling tower or evaporative condenser then hazardous conditions such as no flow and low flow portions of the piping, equipment siting that inhibits access to the equipment for the required maintenance, vapor and water droplets discharging into occupied spaces and so on should be

the Lewis number is determined from experimental data for counterflow splash and crossflow film fill

The paper will cover the benefit and pitfalls of supplemental cooling

A reduction in the recool temperature of the water sent back to the condenser of 2 to 3K can be achieved compared to typical wooden splash packings

has not been a problem in Texas

We have gotten more sophisticated in determining and controlling the natural frequency of drive shafts

The available published literature is reviewed briefly

Change in corrosion rates and in the amount and type of suspected matter in the water was noted

Thermal Design Worksheet:

Eastern New Mexico and southern Kansas

This paper addresses a solution to this problem encompassing initial ideas

With this information to design a suitable instrument for psychrometric measurements

The root cause analysis recommended immediate investigation into the mechanical integrity of all plant cooling tower fans and vibration detection equipment
