Adiabatic cooling: what is and how does it work Frigel ...

It has 2 working modes: 1. “Dry” Mode. During most of the year, the unit works as a conventional dry-cooler, with no water consumption and the heat transported by the water is dissipated in the ambient air by convection of the air forced by the fans. 2. “Adiabatic” Mode. During high ambient temperature periods and only when the dry mode ...

Air Cooled VS Water Cooled Chiller - ARANER

Water-cooled chiller systems have a cooling tower, thus they feature higher efficiency than air-cooled chillers. Water-cooled chillers are more efficient because they condense depending on the ambient temperature bulb temperature, which is lower than the ambient dry bulb temperature. The lower a chiller condenses, the more efficient it is.
