US Patent:

6928389, Aug 9, 2005

Filed:

Oct 4, 2002

Appl. No.:

10/265220

Inventors:

Michael A. Saunders - Sidney OH, US

Assignee:

Copeland Corporation - Sidney OH

International Classification:

G06F011/30

US Classification:

702182, 702183, 62298, 62467

Abstract:

A system and method for calculating the performance of a compressor wherein the user can select a compressor from a database or retrieve a list of compressors to select from based on application conditions. The system calculates the capacity, power, current, mass flow, EER and isentropic efficiency for each compressor selected. The system has a verification process to assure that the compressor and conditions selected are within a designated operating range, and calculates the performance characteristics of the selected compressor.

Appl. No.:

11/043805

Inventors:

Michael A Saunders - Sidney OH, US

Assignee:

Copeland Corporation LLC - Sidney OH

International Classification:

F04B 51/00

US Classification:

702182, 702183, 62298, 62467

Abstract:

A system and method for calculating the performance of a compressor includes a controller in communication with a cooling system. A database includes compressor specification data. A computer communicates with the controller and accesses the database. A user interface associated with the computer is operable to select a compressor from the database, input application conditions, compare data for the selected compressor to the inputted application conditions, and verify operating limits of the selected compressor based on the compressor specification data and the input application conditions.

Appl. No.:

12/249291

Inventors:

Michael A. Saunders - Sidney OH, US

Assignee:

Copeland Corporation LLC - Sidney OH

International Classification:

G06F 15/00

US Classification:

702182, 702183, 62298, 62467

Abstract:

A computer program and system for calculating the performance of a compressor includes selecting a compressor from a database, inputting application conditions, comparing data for the selected compressor to the inputted application conditions, defining an operating envelope for the selected compressor by defining a series of points representing lower and upper limits of evaporating and condensing temperatures for the selected compressor, determining whether the selected compressor operates within its operating envelope, and calculating the performance of the selected compressor.

International Classification:

F04C 29/06
F04C 29/00
F04C 18/02

Abstract:

Scroll compressor designs are provided to minimize vibration, sound, and noise transmission. The scroll compressor has a bearing housing, and orbiting and non-orbiting scroll members. The non-orbiting scroll member has a radially extending flanged portion with at least one aperture substantially aligned with the axially extending bore. At least one fastener is disposed within the aperture and the bore. A sound isolation member contacts at least one of the non-orbiting scroll member, the fastener, or the bearing housing, to reduce or eliminate noise transmission. The sound isolation member may be formed of a polymeric composite having an acoustic impedance value greater than the surrounding materials. The sound isolation member may be an annular washer, an O-ring, or a biasing member, by way of non-limiting example. In other variations, fluid passages are provided within the fastener and/or bearing housing to facilitate entry of lubricant oil to further dampen sound and noise.
