| 20090133866 | HYBRID AIR AND LIQUID COOLANT CONDITIONING UNIT FOR FACILITAATING COOLING OF ONE OR MORE ELECTRONICS RACKS OF A DATA CENTER - A hybrid air and liquid coolant conditioning unit is provided for facilitating cooling of electronics rack(s) of a data center. The unit includes a first heat exchange assembly, including a liquid-to-liquid heat exchanger, a system coolant loop and a facility coolant loop, and a second heat exchange assembly, including an air-to-liquid heat exchanger, an air-moving device, and the facility coolant loop. The system coolant loop provides cooled system coolant to the electronics rack(s), and expels heat in the liquid-to-liquid heat exchanger from the electronics rack(s) to the facility coolant. The air-to-liquid heat exchanger extracts heat from the air of the data center and expels the heat to the facility coolant of the facility coolant loop. The facility coolant loop provides chilled facility coolant in parallel to the liquid-to-liquid heat exchanger and the air-to-liquid heat exchanger. In one implementation, the hybrid coolant conditioning unit includes a vapor-compression heat exchange assembly. | 05-28-2009 |
| 20090126910 | APPARATUS AND METHOD FOR FACILITATING SERVICING OF A LIQUID-COOLED ELECTRONICS RACK - Apparatus and method for facilitating servicing of a liquid-cooled electronics rack are provided. The apparatus includes a coolant tank, a coolant pump in fluid communication with the coolant tank, multiple parallel-connected coolant supply lines coupling the coolant pump to a coolant supply port of the apparatus, and a coolant return port and a coolant return line coupled between the coolant return port and the coolant tank. Each coolant supply line includes a coolant control valve for selectively controlling flow of coolant therethrough pumped by the coolant pump from the coolant tank. At least one coolant supply line includes at least one filter, and one coolant supply line is a bypass line with no filter. When operational, the apparatus facilitates filling of coolant into a cooling system of a liquid-cooled electronics rack by allowing for selective filtering of coolant inserted into the cooling system. | 05-21-2009 |
