A modular data center includes a fan creating a first cooling wind from outside air, an air conditioner creating a second cooling wind having a temperature lower than that of the outside air, racks housing electronic devices that take in the first and the second cooling wind, and a control unit adjusting an air volume of the first cooling wind by controlling the fan, and so as to cool the electronic device to a specified temperature. The control unit executes stopping the air conditioner when a first assumed value of a sum of air-conditioning power of the air conditioner and the fan is smaller than a current value of the air-conditioning power, and operating the air conditioner when a second assumed value of the sum of air-conditioning power of the air conditioner and the fan is smaller than the current value of the air-conditioning power.

An air handling unit, particularly for data center cooling, operates to cool a flow of return air from a conditioned space using a flow of ambient air. The return air is recirculated to the conditioned space as supply air. The flow of ambient air can be adiabatically cooled to a lower temperature to provide additional cooling. A flow of makeup air can be joined with the cooled return air to form the supply air, and can be sourced from the ambient environment directly or from the heated flow of ambient air.

Disclosed is an electrical cabinet with associated air flow direction and heat separation control system. The cabinet has a front, rear, a first side and a second side. The front side has openings to accept flow of cool air into the cabinet and the rear side has openings for exit of warm air from the rear side of the cabinet. The front, rear, first side and second side define an interior space are configured to house heat generating electrical equipment. A frame is adjacent the rear side of the cabinet. The frame has a first frame side and a second frame side. Louvers are located adjacent the rear of the cabinet. The louvers extend between the first frame side and the second frame side. Each louver has a face positioned at an angle to direct the warm air exiting the cabinet other than perpendicular to the rear of the cabinet. A first compartment for storing heat generating equipment is positioned above or below a thermally separated second compartment for storing heat sensitive equipment.

A modular data center includes a cooling module with a cooling module enclosure and a first cooling unit housed within the cooling module enclosure. The cooling module enclosure includes a first interface side wall with a first cooling module supply opening that receives a first portion of cooling air from the first cooling unit. The center further includes a data module with a data module enclosure for housing data equipment. The data module enclosure includes a second interface side wall with a first data module supply opening that receives the first portion of cooling air from the first cooling module supply opening such that the first portion of cooling air flows into the data module enclosure and removes heat from the data equipment.

A method and an arrangement for air-conditioning a cold aisle which is partially bounded by heat-generating devices and is arranged in a hot room, the hot room being separated from a second room by a boundary wall, and a region of the boundary wall is formed by a heat exchanger, such that air that is conveyed through the heat exchanger by the fan is supplied to the cold aisle. An opening with a fan is provided in the boundary wall. The cold aisle is connected to the boundary wall so that the opening is surrounded by the cold aisle.

A data processing equipment structure includes a plurality of vertical and horizontal frame components, which, together, define an equipment structure frame, and a plurality of panels disposed relative to the equipment structure frame to define a periphery. At least one of the plurality of vertical and horizontal frame components is an extruded strut having a generally uniform cross-section. The extruded strut includes an outwardly-facing channel extending along each of a pair of opposing sides of the extruded strut, at least one of which includes a set of evenly-spaced ridges, extending along each of two sides of the channel, for accommodating a threaded fastener. The extruded strut further includes one or more ledges, each having a depth sufficient to accommodate a thickness of one of the plurality of panels.

In a machine room in which an air conditioner and ICT devices are installed, a partition is installed on a side, facing the air conditioner, of an aisle between two ICT devices that are installed so that air intake surfaces of the two ICT devices face each other.

In some examples, a system uses ambient air from outside a controlled airflow environment to cool equipment within the controlled airflow environment. The system can include ductwork that seals the ambient air from air outside of the ductwork within the controlled airflow environment. The system can further include a passive heat exchanger connected to the equipment and extending into an interior of the ductwork to allow heat exchange between the equipment and the ambient air. The system can further include a fan to flow the ambient air through the ductwork, the fan being connectable to the equipment to allow the equipment to control the operation of the fan.

An electronic equipment enclosure includes a frame structure at least partially enclosed by a plurality of panels defining a compartment in which one or more electronic components are mounted and an exhaust air duct that is adapted to segregate hot air being exhausted from the compartment from cool air entering the compartment, thereby improving thermal management of the enclosure. The exhaust duct includes a lower duct section extending upward from the top panel of the compartment and an upper duct section telescoping upward from an upper end of the lower duct section. Each duct section includes four panels connected together by hinged corner fittings such that the section is collapsible. The upper duct section includes an outwardly flared portion.

A data center that houses an electronic device, the data center includes a plurality of air-current-supply-sections that supply an air current to the electronic device, a plurality of shields that are provided for the air-current-supply-sections to shield corresponding air-current-supply-sections, and a control section that acquires status information indicative of a status of the electronic device from the electronic device, controls a flow rate of the air current supplied from each of the air-current-supply-sections in accordance with the acquired status information, checks the air-current-supply-sections to locate an air-current-supply-section whose air current flow rate is not higher than a predetermined value, checks the shields to locate a shield corresponding to the air-current-supply-section whose air current flow rate is not higher than the predetermined value, and causes the located shield to shield the located air-current-supply-section.
