US Patent:

8205508, Jun 26, 2012

Filed:

Jan 12, 2010

Appl. No.:

12/686004

Inventors:

Christopher J Healey - Manchester NH, US

Assignee:

Meggitt (New Hampshire), Inc. - Londenderry NH

International Classification:

G01F 1/80
G01F 15/00

US Classification:

73861352, 7386177

Abstract:

A motorless mass flowmeter in accordance with one embodiment of the invention comprises a turbine subassembly, a drum, and an impeller. The drum is rigidly connected to the turbine subassembly such that the drum rotates in accompaniment to rotation of the turbine subassembly. The impeller is rotationally coupled to the drum by way of a spring that allows relative rotation against the bias of the spring. The turbine subassembly has jets and bypass valves. The turbine subassembly may be implemented in the form of a laminated bypass valve structure. The laminated bypass valve structure may include an entrance layer having entrance port(s), a closure layer having closure member(s), an exit layer defining exit passage(s), and an intermediary layer forming conduit(s) for guiding fluid from entrance port(s) to exit passage(s).

Appl. No.:

12/416567

Inventors:

James W. VanGilder - Pepperell MA, US
Christopher M. Healey - Atlanta GA, US

Assignee:

American Power Conversion Corporation - West Kingston RI

International Classification:

G06F 17/10

US Classification:

703 6

Abstract:

A system and method for designing aspects of a cooling system for a data center is provided. A method is provided including computing cooling redundancy at each rack position in a data center, in real time. The redundancy can be reported using the traditional N+1, N+2, etc. notation, where N is the number of coolers required to meet the primary cooling load type specification. The redundancy can also be reported in terms of a Cooling Reliability Index (CRI) which also takes into account the inherent availability of the specific cooling units in the design.

Assignee:

American Power Conversion Corporation - West Kingston RI

International Classification:

G01K 17/00

US Classification:

702136

Abstract:

A system and method for evaluating equipment in a data center, the equipment including a plurality of equipment racks, and at least one cooling provider. In one aspect, a method includes receiving data regarding each of the plurality of equipment racks and the at least one cooling provider, the data including a layout of the equipment racks and the at least one cooling provider, and a power draw value for each of the equipment racks, storing the received data, determining air flow between the at least one cooling provider and each of the equipment racks, determining inlet and exit air temperature for the at least one cooling provider based on the layout, the power draw and the airflow, for each equipment rack, determining inlet and exit air temperature based on the layout, the power draw and the airflow, and displaying an indication of the inlet and exit temperature for each of the plurality of equipment racks and the at least one cooler. In the method, determining the inlet and exit temperature of each of the equipment racks and the at least one cooling provider includes establishing a set of S coupled equations, with S equal to a number of temperature values to be determined, and solving the S coupled equations.

International Classification:

G06F 17/10

US Classification:

703 2

Abstract:

A system and method for predicting airflow within a data center using a potential flow technique is provided. In one aspect, a method includes automatically generating an unstructured grid, the unstructured grid comprising a plurality of unstructured grid cells, each unstructured grid cell having a size, dividing a representation of the data center into the plurality of unstructured grid cells, determining airflow velocity values for each of the plurality of unstructured grid cells using airflow velocity potentials, determining a temperature value for each one of the plurality of the unstructured grid cells using the airflow velocity values, determining a concentration value for each of the plurality of the unstructured grid cells using the airflow velocity values, and calculating a comparison result indicating whether the concentration values, the airflow velocity values and the temperature values for the plurality of the unstructured grid cells satisfy convergence criteria.

International Classification:

G01K 1/02

US Classification:

Abstract:

A computer-implemented method for evaluating cooling performance of equipment in a data center. In one aspect, the method comprises receiving data related to equipment in the data center, determining first parameters related to airflow and temperature in the data center at a first period in time, receiving a description of a transient event affecting one of airflow and temperature in the data center at a second time, breaking a second time period subsequent to the second time into a plurality of time intervals, determining second parameters related to airflow in the data center during one of the time intervals, determining the parameters related to temperature in the data center at each of the time intervals based on the second parameters related to airflow, and storing, on a storage device, a representation of the parameters related to temperature in the data center during the second time period.
