Abstract: The present invention relates to a cooling apparatus and method wherein a supply sump and turbine are below grade. Water cooled from an above grade cooling tower fan and fill flows into the supply sump and is pumped through below grade pipes into a facility. Heat rejected water from the facility then flows through below grade pipes into a below grade collector sump. A collector sump pump pumps the heat rejected water above grade into a nozzle and back into the fill to be cooled. The present invention is constructed such that water is not idle in any above grade component. Accordingly, the risk of water freezing within the above grade components is drastically reduced. Moreover, the heat rejection water can by-pass all above grade components and travel directly into the supply sump in the event of reduced load from the facility.

Abstract: A cabinet adapted to house electronic and communication equipment therein. The cabinet includes modifiable top, bottom and side walls. Grommets with notches are provided to accommodate passage of wires and cables into and out of the cabinet. The notches function to receive the wires and/or cables and to mitigate passage of air through the grommet. A micro controller is provided for each individual cabinet to both monitor and control variants within the cabinet. The micro controller may be accessed on site with a local operator, or remotely through a memory addressable system.

Abstract: Cabinets or enclosures are provided having heat generating elements stored therein cooled by locating the cabinets on tiles of an elevated floor having cool air provided under the tiles, the cabinets having variable size openings in their bottom surface located over openings in the tiles, openings in the top surface of the cabinets, which openings may have fans located in the openings, highly perforated shelves and a highly perforated front door. By controlling the size of the various openings, and the number, if any, of fans and air flow through the door the temperature in the cabinet may be controlled. A number of cabinets may be located side-by-side with side walls in contact and with wires introduced into one cabinet from under the tiles through an opening in its bottom wall being passed from cabinet-to-cabinet through aligned openings in the side walls of the cabinets.

Abstract: A cooler for an air conditioning system or other system having a heated surface to be cooled has an array of nozzles for issuing a fine spray of liquid. A fan of the cooler induces flow of air over a surface to be cooled, the nozzles issuing into the flow of air the fine spray at a distance from the heated surface such that the liquid of the fine spray is fully evaporated prior to contact with the heated surface. Drop sizes of 20 to 30 microns are typical.
