Abstract: An automated refrigerant recharging system determines whether a cooling load parameter of a direct expansion (DX) cooling system that cools information technology (IT) modules of an information handling system (IHS) has reached a defined recharging threshold that results in a response of the pressure value for measurement by the pressure transducer. In response to the cooling load parameter being equal to or greater than the defined recharging threshold, a controller determines whether a pressure value of the refrigerant of the DX cooling system is less than a defined target pressure value corresponding to the defined recharging threshold. In response to determining that the pressure value of the refrigerant of the DX cooling system is less than the defined target pressure value, the controller autonomously opens a control valve to transfer refrigerant to the DX cooling system.

Abstract: A cooling system, large-scale information handling system (LIHS), and method avoid vapor condensation in information technology (IT) modules by operating all air handling units (AHU) in the same mode of operation. An AHU supervisory controller of the cooling system determines whether a trigger condition exists that indicates a risk of vapor condensation in the at least one IT module within LIHS that is cooled by more than one AHU. Each AHU directs the intake of cooling air in a selected mode of operation from among: (i) an outside air mode; and (ii) a mechanically cooled air mode. In response to determining that the trigger condition exists, the AHU supervisory controller triggers all AHUs to operate in a mode of operation selected to avoid condensation.

Abstract: Cooling system of modular data center (MDC) has air handling unit (AHU) that circulates cooling air through information technology (IT) module(s). Transducer(s) sense first air characteristic value of cooling air directed to IT module(s) of MDC, the value being selected one of: (i) temperature value; and (ii) humidity value. AHU controller determines whether first air characteristic value satisfies first air characteristic criterion of one of: (i) a temperature value equal to or greater than minimum temperature threshold; and (ii) a humidity value equal to or less than maximum humidity threshold. In response to determining that first air characteristic criterion is not satisfied, AHU controller triggers supplemental heater to warm cooling air before cooling air comes into contact with IT module(s) inside of MDC to at least one of: (i) provide cooling air above minimum operating temperature of components within IT module(s); and (ii) prevent condensation.

Abstract: A controller of a large-scale information handling system (LIHS) includes a memory containing visual representations of architecture and sub-architecture associated with respective data center (DC) configurations. An interactive component-level visual monitoring and control (ICVMC) system includes a processor in communication with the component level monitors and the memory and includes an ICVMC module executing on the processor to receive identification information from one or more component-level monitors of a DC. The DC includes-functional components operationally configured and interconnected in a core architecture in a first DC configuration and monitored respectively by the one or more component-level monitors. The ICVMC module determines the first DC configuration and associated core architecture based on the received identification information.
