Examples of hybrid cooling System for datacenters are disclosed. In an example, the hybrid cooling system includes a chiller plant to provide supply of coolant, an air-cooling unit (ACU), and a coolant distribution line. The coolant distribution line comprises a first portion, a second portion, and a third portion in series fluid communication. The ACU receives supply of the coolant from the chiller plant via the first portion. The hybrid cooling system further includes a coolant distribution unit (CDU) coupled to an electronic component in the data hall. The ACU and the CDU are in series fluid communication via the second portion of the coolant distribution line and the coolant egressing the ACU passes through the second portion to be fed back to the CDU. The hybrid cooling system includes a heat exchanger in series fluid communication with the CDU via the third portion of the coolant distribution line.

An example system includes an enclosure housing electronics that generate heat. The enclosure includes a vent leading to an exterior of the enclosure. The vent is configured to allow the heat generated by the electronics to escape to the exterior. The enclosure includes an inlet configured to direct air into the enclosure. The vent and the inlet are arranged so that the heat escaping from the vent suctions the air through the inlet. The example system also includes a radiator having an input port and an output port. The input port is located exterior to the enclosure and the output port is connected to the inlet so that the air suctioned through the inlet causes air from the exterior to enter the radiator through the input port and to pass to the output port. The radiator is submerged, at least in part, in a coolant.

According to some embodiments, a hermetically sealed container may have sides defining an interior portion that is able to hold gas at high pressure, such as at least substantially 2 times standard atmospheric pressure. One or more data center computer servers may be located within the interior portion and the high pressure may improve heat transfer for a data center. At least one side of the container may include a hermetically sealed electrical and/or optical feed-through providing an ability to connect the computer server to an element outside of the interior portion (e.g., a power source and/or another data center computer server) and a mechanism to remove heat from the container, such as a liquid loop heat exchanger, etc.

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.

A power electronics system comprising a environmentally sealed electronics compartment for housing power electronics equipment is provided. The system includes a plenum within the sealed electronic compartment for circulating air. A first liquid cooling loop is configured to cool air flowing through the plenum. A second liquid cooling loop configured to directly cool the power electronics equipment. The system includes a controller configured to independently control the flow rate of the first liquid cooling loop and the second liquid cooling loop.

A data center includes heat producing components and an air handling system that provides reduced relative humidity air to cool the heat producing components. The air handling system includes a thermal storage unit that removes thermal energy from incoming air under a given set of ambient air conditions and releases thermal energy into incoming air under another set of ambient air conditions. Under the given set of ambient air conditions, the thermal storage unit cools the incoming air and causes water vapor to condense out of the incoming air. Under the other set of ambient air conditions, the thermal storage unit releases thermal energy into the incoming air, thus heating the incoming air.

An assistance apparatus according to the disclosure generates monitor area data on the basis of dimension data of rack rows that are each constituted by a plurality of racks and that are arranged in a first direction in a three-dimensional space, the dimension data including the length of each rack row in the first direction and the height thereof in a second direction perpendicular to the first direction, interval data that includes an interval, in a third direction, between the rack rows adjacent to each other in the third direction, the third direction being perpendicular to the first and second directions, field-of-view angle data that includes the field-of-view angle of each temperature sensor, and temperature sensor position data that indicates certain temperature sensor positions; and includes a display control unit that displays monitor coverage information on a display device on the basis of the monitor area data.
