An environmental control system for a telecom shelter integrates with a native HVAC system for exchanging interior air in a conditioned space in a machine room, telecom enclosure, or other closed machine environment by forcing or directing cooler outside air to replace interior air without active refrigeration by the native HVAC system. Primary cooling and heating of the conditioned space in the enclosure is performed by an exchange system and control logic that identifies, based on sensory input, when outside air exchange is more efficient than native AC (Air Conditioner) operation. The native AC system is suppressed or inhibited, and primary environmental control performed by fan driven exchange of outside air with air in the enclosure. Sensors and timers identify appropriate periods to defer control to the native AC system for cooling demand in excess of outside air exchange capability, and also identify ongoing suppression, or “takeback” of cooling control from the native system when erroneous, erratic or mistaken operation results in excessive or insufficient cooling, resulting from such factors as equipment failure, operator error, and environmental/disaster occurrences.

A computing system includes a cabinet, an inlet temperature sensor, a cooling device, an environmental sensor, and at least one processor. The cabinet houses at least one computing device. The inlet temperature sensor is configured to detect inlet temperature data for the at least one computing device. The inlet temperature data represents internal temperature within the cabinet. The cooling device is coupled to the cabinet for maintaining temperature within the cabinet. The environmental sensor is configured to detect environmental temperature data external to the cabinet. The environmental temperature data represents external temperature outside the cabinet. The at least one processor is configured to: (a) determine if one or more of the inlet temperature data and the environmental temperature data exceeds a temperature range; and (b) in response to the temperature range being exceeded, generate a first warning signal indicating a temperature problem.

Systems, methods, and other embodiments associated with unified control of cooling in computers are described. In one embodiment, a method locks operation of first and second cooling mechanisms configured to cool one or more components in the computer. In response to a first condition, the method unlocks the operation of the first cooling mechanism to allow the first cooling mechanism to make cooling adjustments while the operation of the second cooling mechanism is locked. In response to a second condition, the method unlocks the operation of the second cooling mechanism to allow the second cooling mechanism to make cooling adjustments while the operation of the first cooling mechanism is locked. In the method, the first cooling mechanism and the second cooling mechanism are prevented from making the cooling adjustments simultaneously.

A system for determining and displaying in a graphical user interface one or more of air temperature, pressure, or velocity in an information technology (IT) room including an IT equipment rack comprises a processor configured to receive an input comprising airflow resistance parameters through the rack, an IT equipment airflow parameter, a heat-dissipation parameter, an external pressure, and an external temperature, to run the input through a flow-network solver that solves for airflow velocities through at least one face of the rack and a rack air outflow temperature based on the input, provide an output including the airflow velocities and the rack air outflow temperature, and generate, based on the output, a display in a graphical user interface of the system illustrating one or more of air temperatures, air pressures, or airflow velocities within the IT room.

A command-and-control module for communications, ideally in military operating conditions, is adapted for easy insertion into, and removal from, a portable case. A chassis has front and rear vertical plates secured, e.g. welded, to a horizontal plate. At least one DIN rail, for securing electrical and electronic equipment, is mounted to a vertical plate. The case has electrical ports and outlets as well as multiple features to protect the sensitive electronic equipment inside. Shock absorbers between the horizontal plate and the inner surface of the case protect the equipment from mechanical shock. A thermoelectric cooler keeps the equipment from overheating. An inner cover protects the equipment from dust. The inner cover is bolted to the chassis. The chassis is not otherwise affixed to the case. When the bolts are removed, the chassis is easily lifted out by handles.

A module panel and method include an exterior housing, at least one heat sink disposed in the housing, a power delivery circuit disposed in the housing and coupled to one side of the at least one heat sink, and a controller circuit disposed in the housing and coupled to an opposite side of the at least one heat sink. The power delivery circuit operates using one or more different voltages than the controller circuit.

An information handling system includes a corrosion controller that may monitor a corrosion sensor array, and determine a type of the corrosion based on a location of a corrosion sensor. The corrosion type may include humidity driven corrosion and non-humidity driven corrosion.

Automatic monitoring of a cooling system and providing warnings of abnormal operation. The cooling system includes one or more air handling units to provide air flow cooling to a plurality of racks of computer equipment, each rack having a display module for indicating an inlet air temperature of the rack and an alert message. The monitoring includes: receiving, from a plurality of sensors, measurements of: an air flow temperature provided to each of the racks; and an air pressure, temperature and relative humidity difference across, and an electrical power consumption of, the air handling unit(s); updating a computer model of the cooling system with the received measurements; and for each rack, if a level or a rate of change of the inlet air temperature is outside of a preset range for the rack, transmitting an alert message to the display module to indicate a cause based on the computer model.
