Abstract: The present disclosure is directed to examples of modular data centers configured to provide cooling to liquid-cooled electronics equipment stored within the modular data centers. In one aspect, a modular data center can be configured to provide cooling without requiring the use of mechanical refrigeration (e.g. vapor-compression or absorption refrigeration), through the use of a dry cooler in combination with an optional evaporative cooler.

Abstract: A communications cabinet includes a housing defining a location for mounting communications equipment, the housing having a wall formed of a first material with a first penetration resistance, a vent opening in the wall, and a door. At least one plate of material having a second penetration resistance greater than or about equal to the first penetration resistance is mounted between the vent opening and the location for mounting the communications equipment, and the plate is positioned to stop projectiles larger than a given size from traveling in a straight line from the at least one vent opening to the location for mounting communication equipment while leaving an airflow path from the vent opening to the location for mounting the communications equipment that passes around at least one edge of the plate of material through a gap between the at least one plate and the wall.

Abstract: An enclosure houses heat-producing equipment and includes an air conditioner, a fan, and at least one controller for controlling the air conditioner and the fan. The controller runs the air conditioner when a temperature of the interior is greater than or equal to an on temperature and turns the air conditioner off when the temperature of the interior is less than or equal to an off temperature. If the ambient temperature outside the enclosure is less than the off temperature and the air conditioner is off, the controller turns the fan on until the temperature of the interior is less than the off temperature by a first amount and then turns the fan off. Also a method for controlling the temperature of an enclosure using an air conditioner and a fan.

Abstract: An outdoor communication cabinet includes a housing having a interior, an opening into the interior and a door connected to the housing at the opening that includes a first aperture and a first fan tray with a plurality of fans, the fan tray being hingedly connected to the door for movement between first and second positions relative to the first aperture. Also a method of detecting blockage of filters in a communication cabinet.
