MODULAR ADIABATIC PRE-COOLING CASSETTE WITH METHOD OF RETROFIT FOR HORIZONTAL AIR-COOLED COMMERCIAL REFRIGERATION CONDENSERS
According to another aspect, the present disclosure relates to a system for modular adiabatic evaporative pre-cooling of a horizontal air-cooled commercial refrigeration condenser. The system includes an evaporative media with an air permeable construction. The evaporative media has a water absorbable construction. The system also has a water supply port for supplying the volume of water. The system also has a water distributer for distributing the volume of water supplied from the water supply port. The water distributer distributes the volume of water to the evaporative media. The system also includes a water drain port for draining the volume of water distributed to the evaporative media.
