  • Publication number: 20180266731
    Abstract: Systems and methods relating to a plural in-series pumped liquid refrigerant trim evaporator cycle are described. The cooling systems include a first evaporator coil in thermal communication with an air intake flow to a heat load, and a first liquid refrigerant distribution unit in thermal communication with the first evaporator coil. The cooling systems further include a second evaporator coil disposed in series with the first evaporator coil in the air intake flow and in thermal communication with the air intake flow, and a second liquid refrigerant distribution unit in thermal communication with the second evaporator coil. A trim compression cycle of the second liquid refrigerant distribution unit is configured to further cool the air intake flow through the second evaporator coil when the temperature of the first fluid flowing out of the main compressor of the second liquid refrigerant distribution unit exceeds a predetermined threshold temperature.

  • Publication number: 20170268792
    Abstract: The cooling systems and methods of the present disclosure involve modular fluid coolers and chillers configured for optimal power and water use based on environmental conditions and client requirements. The fluid coolers include wet media, a first fluid circuit for distributing fluid across wet media, an air to fluid heat exchanger, and an air to refrigerant heat exchanger. The chillers, which are fluidly coupled to the fluid coolers via pipe cages, include a second fluid circuit in fluid communication with the air to fluid heat exchanger and a refrigerant circuit in thermal communication with the second fluid circuit and in fluid communication with the air to refrigerant heat exchanger. Pipe cages are coupled together to allow for expansion of the cooling system when additional cooling capacity is needed. The fluid coolers and chillers are configured to selectively operate in wet or dry free cooling mode, partial free cooling mode, or mechanical cooling mode.

  • Patent number: 9763366
    Abstract: A space-saving, high-density modular data pod and a method of cooling a plurality of computer racks are disclosed. The modular data pod includes an enclosure including wall members contiguously joined to one another along at least one edge of each wall member in the shape of a polygon and a data pod covering member. Computer racks arranged within the enclosure form a first volume between the inner surface of the wall members and first sides of the computer racks. A second volume is formed of second sides of the computer racks. A computer rack covering member encloses the second volume and the data pod covering member form a third volume coupling the first volume to the second volume. An air circulator continuously circulates air through the first, second, and third volumes. The method includes circulating air between the first and second volumes via the third volume and the computer racks.

The air flow distribution system may include a convex ceiling member above the second air foil. A corresponding method includes causing air to be directed between a first air foil disposed above a server rack and a second air foil disposed above the first air foil to form turbulent wake patterns in the cold aisle.
