Case study: Chelsea FC - Adiabatic Cooling Project
A controls contractor was asked to sort out the adiabatic cooling controls. We were contacted since there was a water treatment system providing the water to the spray system at the AHU intakes.
Adiabatic cooling works by spraying water onto a surface. As the water evaporates it takes heat energy without this cooling the surface from which it evaporated, this affording cooling. It is important that the system uses high quality water to prevent scaling. Overtime scale build-up blocks spray nozzles and reduces heat transfer efficiency. However scale can provide environments in which bacteria can live and breed, like Legionella.
IWT has maintained this system for a number of years. We clean and chlorinate the system, and have set up adiabatic controls.
IWT now looks after the water softeners on site, we clean and chlorinate the tanks, maintain the Keraflo valves on the tanks, and generally provide indepth knowledge and technical backup.
