    Abstract: The cooling systems of the present disclosure include a first refrigerant circuit in thermal communication with a heat load and in fluid communication with a main condenser, a free cooling circuit in fluid communication with the main condenser and a free-cooled water source, a chilled water circuit in fluid communication with the main condenser and an evaporator, and a second refrigerant circuit in fluid communication with the evaporator and a secondary condenser. The free cooling circuit is in thermal communication with the first refrigerant circuit via the main condenser, the chilled water circuit is in thermal communication with the first refrigerant circuit via the main condenser, and the second refrigeration circuit is in thermal communication with the chilled water circuit and the free cooling circuit. The second refrigeration circuit cools a fluid flowing in the chilled water circuit. Methods of operating a cooling system are also disclosed.

    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.

    Abstract: A cooling system includes a heat exchanger having one or more rows of multiple flat tubes, louvered fins disposed between pairs of flat tubes, and special header tube connections to form a counter flow heat exchanger. Heat exchangers having multiple rows may be placed near or close to the server racks and may be in fluid communication with an outdoor heat exchanger having one or more rows. A single-phase fluid is pumped through a fluid circuit or loop, which includes the heat exchangers at the server racks and the outdoor heat exchanger. The single-phase fluid circuit including the heat exchangers at the IT racks may alternatively be in thermal communication with a water circuit that includes an outdoor fluid cooler. The flat tubes can be formed tubes with one or more channels, or extruded tubes with multiple channels. The heat exchangers include header tubes/connections, which facilitate easy fabrication and connection between rows and inlet/outlet, and lower the pressure drop.

    Abstract: Modular air cooling and distribution systems include a fan and heat exchanger cooling assembly and a controller which controls the fan speed based on temperature and velocity measurements. The cooling assembly includes a fluid-to-air heat exchanger and a variable speed fan. The fluid in the fluid-to-air heat exchanger may be propylene glycol or water. The heat exchanger minimizes pressure drop and maximizes heat transfer. The quantity of cooling assemblies is selected to match the indoor cooling requirements. The cooling assemblies are easily assembled together, stacked vertically, and/or connected horizontally, to match the cooling load. If additional cooling capacity is needed in the future, more cooling assemblies can easily be added, and the cooling assemblies may be expanded vertically and/or horizontally. The speed of the fans of the fan and heat exchanger assemblies are controlled based on fluid temperature and fluid velocity measurements, which may be obtained by an anemometer.
