A highly integrated mobile energy storage system is provided, which includes a container and battery racks. The battery racks are arranged in two rows along a length direction of the container, and the two rows of the battery racks are arranged back to back. For each of the two rows of battery racks, a maintenance door is arranged at a wall of the container close to the row of battery racks. In a case that a battery rack needs to be maintained, it is just required to open the maintenance door to maintain the battery rack. Since the two rows of battery racks are arranged back to back, no maintenance passage is required, thereby reducing a floor space along a width direction of the container, thus reducing the floor space of the system.

A closed cold pool system is disclosed. The closed cold pool system may include a first closing assembly, a cabinet assembly and a second closing assembly. The first closing assembly is provided on a front side of the cabinet assembly to form a first closed cold aisle, and the second closing assembly is provided on a rear side of the cabinet assembly to form a second closed cold aisle. The cabinet assembly may include a power distribution cabinet, an in-row air conditioner and a main device unit that are provided side by side. The in-row air conditioner may include a front air supply opening, a rear air supply opening and a top air return opening. The front air supply opening is communicated with the first closed cold aisle, and the rear air supply opening is communicated with the second closed cold aisle.

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.

The present disclosure relates to a roof mounted modular cooling unit (“RMC unit”) which is adapted for use above a unit IT structure being used to help form a data center. The RMC unit has a housing configured to be secured perpendicularly relative to a longitudinal axis of a frame of a modular unit IT structure. The housing has a cold air discharge compartment at one end thereof, overlaying a cold aisle formed within the unit IT structure, from which cold air from the modular cooling unit is discharged into the cold aisle, and a hot air intake compartment selectively located to overlay the hot aisle, into which hot air from the hot aisle is drawn. A width of the RMC unit is sufficient to substantially span a full width of the one of the equipment racks.

A modular data center (MDC) has a cooling unit externally positioned proximate to a first longitudinal external wall of a volumetric container. The cooling unit directs supply air sideways through a supply air opening into a cold aisle adjacent to the first longitudinal external wall. The cooling air passes through rack(s) containing information technology (IT) components to a hot aisle. A baffle positioned within the volumetric container above the rack(s) directs return air from the hot aisle through a return air plenum to a return air opening in the first longitudinal external wall. A shroud coupled to at least one of the volumetric container and the cooling unit receives the sideways directed return air and directs the return air downward into an upwardly open return air inlet of the cooling unit.

An underground equipment vault system having a body or casing, an intake duct, an intake vent, one or more equipment hangers, an exhaust duct, an exhaust vent, and one or more ventilated compartments. The underground vault system is configured to improve air flow from underneath, or from a low portion of, the body of the vault, provide flexible positioning or location options for the intake vents and the exhaust vents away from the vault body, cool the intake air, and reduce the noise impact of the vault.

An equipment enclosure free air cooling assembly includes an air outlet arranged to deliver air to inside an equipment enclosure and an air inlet arranged to receive air from outside the equipment enclosure. An air flow pathway is provided through which air entering the air inlet must pass to reach the air outlet. An adjustable screen assembly has a screen filter element. An adjustment mechanism is operable to selectively utilize different regions of the screen filter element for filtering air passing through the air flow pathway at different times.

A cooling device includes a fan for blowing air to a control board arranged on the downstream side by rotation of a rotator. The cooling device further includes a bypass structure provided so as to avoid the rotator and configured to oil liquid to flow, at least, from the upstream side of the fan to the downstream side of the fan, and a gutter provided on the upstream side of the fan to lead the oil liquid to the bypass structure.

There is provided a power converter unit that can include an inverter and a plurality of batteries. The power converter unit can include a battery energy storage system (BESS) and an inverter. The BESS and the inverter can share at least one protection circuit.
