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.

Cooling systems and methods using single-phase fluid

An air curtain containment system and assembly for data centers forms an air curtain over the server cabinets thereby separating hot air in a hot aisle from cool ambient air. The air curtain containment system includes ducts which include a hot air intake section that receives hot air discharged from servers, which are disposed in server cabinets. The ducts include heat exchangers for cooling the hot air and at least one air curtain discharge section. A housing is coupled to a wall of the ducts, and includes a cooling edge device fan. The cooling edge device fan is disposed along the ducts, and is configured to draw the hot air for cooling through the heat exchangers. An air curtain fan assembly is disposed along the ducts. The air curtain fan assembly expels cold air through the air curtain discharge section, and thereby forms an air curtain over the server cabinets.

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.

A night cover for a refrigerated merchandiser that is positionable to substantially enclose a product display area of the merchandiser. The night cover includes a first portion and a second portion that is disposed above the first portion. The second portion cooperates with the first portion to define a first surface area, and the second portion defines a second surface area and has an open section configured to permit ambient airflow through the night cover. A ratio of the first surface area to the second surface area is between approximately 7:1 and 18:1.

A heat exchanger includes a plurality of first refrigerant flow tubes in fluid communication with one of a suction line and a liquid line, and a second refrigerant flow tube in fluid communication with the other of the suction line and the liquid line. Each of the first refrigerant flow tubes and the second refrigerant flow tube have microchannels, the second refrigerant flow tube positioned between and cooperates with the first refrigerant flow tubes to heat vapor refrigerant flowing in the suction line, the refrigerant directed to or exiting the second refrigerant flow tube flows around a portion of at least one of the first refrigerant flow tubes.

A fan plenum for a refrigerated merchandiser, in which the refrigerated merchandiser includes a case defining a product display area and a lower flue, a first air passageway, and a second air passageway, and in which the first air passageway and second air passageway are in fluid communication with the lower flue and with the product display area, includes a top wall including a fan aperture for receiving a fan having a plurality of fan blades. The fan plenum further includes a side wall and a plenum base. An airflow divider partitions the fan plenum into a first duct and a second duct. The first duct is fluidly couplable with the first air passageway and the second duct is fluidly couplable with the second air passageway.

Merchandiser with airflow divider

A multi-zone heat exchanger has a first end and a second end and a width divided into a plurality of parallel airflow zones. Each zone defines an airflow section of the heat exchanger that receives a portion of the airflow through the heat exchanger. A first tube of continuous construction is coupled to an inlet port and to an outlet port and forms a first refrigerant circuit spanning three or more passes from the first end to the second end. The first refrigerant circuit passes between at least two zones of the plurality of zones. A second tube of continuous construction is coupled to the inlet port and to the outlet port and forms a second refrigerant circuit spanning three or more passes from the first end to the second end. The second refrigerant circuit passes between the at least two zones of the plurality of zones.

A merchandiser including a case that defines a product display area. The case includes a canopy that has a first air outlet in fluid communication with a primary air passageway within the case to direct a primary air curtain into the product display area, and a second air outlet in fluid communication with a secondary air passageway within the case to direct a secondary air curtain into the product display area. The merchandiser also includes a divider that is coupled to the canopy between the primary air passageway and the secondary air passageway. The divider provides airflow communication between the primary air passageway and the secondary air passageway upstream of the first and second air outlets.

An LED illumination system is operable to irradiate plant materials with photosynthetically active radiation. A lighting assembly includes a plurality of different LED types. Each LED lamp has a different spectral power matched to an absorption peak of the plant materials. All of the LED lamps of each different lamp type are driven by a different dedicated power source. Each power source can be independently modulated to vary the collective spectral power output of the LED illumination system. The lighting assembly includes fluid conduits disposed proximate to the LED lamps and a cooling fluid is flowed through the fluid conduits to removed thermal energy from the LED lamps.

A merchandiser including a case that has an air inlet and defines a product display area with a customer access opening. The merchandiser also includes a canopy that has a first air outlet and a second air outlet, a first passageway connecting the air inlet with the first air outlet to direct a first airflow through the first air outlet at least partially across the opening to define a primary air curtain, and a second passageway in fluid communication with a HVAC system by ducting coupled between the merchandiser and the HVAC system to direct a second airflow defining a secondary air curtain from the HVAC system through the second air outlet at least partially across the opening. The primary and secondary air curtains cooperate with each other to minimize infiltration of ambient air into the product display area.
