Fit Atrix Solution Scenarios-Air-cooled Fit Atrix micromodule (air-cooled) is a solution to use outdoor air to cool the computer room. The cabinets are arranged in a face to face and back to back way, and the components within the cabinets are cooled by cool air which is sent out by the dedicated inter-column air conditioner in the computer room, and then enters the front of cabinets from the cold channel. Different from the chilled water scenario, air cooling is achieved by directly cooling the refrigerant in the condenser through the outside air.
