82-06: The New CTI Sound Code - Interpretation and ApplicationA new CTI Code, ATC 128, standardizing the measurement of sound from water cooling towers was recently adopted. The highlights of this code will be reviewed. The implications of the code will be examined regarding current instrumentation that will and will not be acceptable along with techniques required but not explicitly stated in the Standard.

Refrigerating and Air-conditioning Engineers (ASHRAE) has developed a proposed Standard Practice that specifies what is required to prevent legionellosis associated with building water systems

These criteria are used

It will discuss aftermarket changes that make things worse

The composite spacers have proven their effectiveness through two years of service

how much they cost to start and maintain

This is particularly true in areas like the Western and Southwestern states and Mexico where the feed raw water has high silica

A properly designed polymer feed system is the key for achieving superior performance and cost-effective solid-liquid separation

The changes in the moving air (such as pressure drop or humidity ratio) occurring in the rain zone are described as a dependence of the flow ratings of the air and water

Oxidization of bromide ion with ozone is known to produce the hypobromous acid/hypobromite ion (HOBr/Obr) couple

the circulation pumps and distribution piping system were hydraulically limited

maintenance history and efficiency comparisons will be presented
