17-19: Should EDF Switch from EN 14705 Long Term Performance Tests to ATC-105As the owner of 32 large cooling towers, EDF has been performing its own thermal performance acceptance tests during the past 30 years. The company invests a lot in verifying as accurately as possible that a cooling tower reaches the guaranteed year average performance. EDF uses a long term test procedure developed by EDF Research department during the 80s. Long Term means data acquisition running from 3 to 9 months which implies specific attention

Utilizing both the VFD’s and increased efficiency

This paper discusses ways to reduce maintenance cost

By the year 2000

sufficient water is evaporated from these cooling towers to cover 500 acres with an inch of water each day

as well as analytical data on material of construction options

the performance and mechanical reliability of an Air- Cooled Condenser (ACC) is affected

The effect of the end conditions is discussed and an appropriate end condition is presented

these metals suffer from corrosion in acidic-to-neutral and highly halogenated environments that are common in cooling water systems

A multi-functional cooling water treatment chemical is applied to a cooling tower system using a diffusion-based technology utilizing patented coated tablets
