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).

Inventors:

Christopher M. Healey - Chelmsford MA, US

Assignee:

AMERICAN POWER CONVERSION CORPORATION - West Kingston RI

International Classification:

G06F 17/10
G06F 1/20

US Classification:

703 2

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 method substantially reduces the computational complexity of computing cooling redundancy.

International Classification:

H05K 7/20

US Classification:

36167946

Abstract:

A computer-implemented method for sequential placement of cooling resources in a data center comprises: defining a weighted, higher-order cooling metric, , representing an overall performance of the cooling resources in the data center; enumerating all possible locations in the data center for placing an additional c cooling resources; and placing the c cooling resources in locations in the data center for which is closest to an optimum value. For a performance metric M, the weighted, higher-order cooling performance metric can be defined aswhere R represents a number of racks in the data center, C represents a total number of cooling resources placed in the data center, i represents one of the R racks in the data center, Mrepresents a value of metric Mwhen k cooling resources are shut down, and a(i,k) is a weighting function for rack i with the k cooling resources shut down. A system performing the method and computer-readable media having stored thereon instructions causing a processor to perform the method are also provided.

G05B 13/04

Abstract:

Aspects of this disclosure are directed to a simulation-based cooling optimization method that provides real-time cooling set points in a data center. The method combines airflow and temperature simulation, energy modeling, and an optimization solver to determine optimal cooling set point values for a data center. Other aspects are also directed to estimating power consumption and cost and energy savings.
