Determining Long-Term Performance of Cool Storage Systems from Short-Term Tests, Progress Report, 6-99, Revised 12-99
(Energy Systems Laboratory (http://esl.tamu.edu), Texas A&M University, 1999)
This is the Spring 1999 progress report on ASHRAE Research Project RP 1004: Determining Long-Term Performance of Cool Storage Systems from Short-Term Tests. This report presents an update concerning the work that has been ...
Reduce Building Energy Consumption by Improving the Supply Air Temperature Schedule and Recommissioning the Terminal Boxes, Submitted to the Energy Management and Operations Division at the M.D. Anderson Cancer Center
(Energy Systems Laboratory (http://esl.tamu.edu), Texas A&M UniversityDepartment of Mechanical Engineering, Texas A&M University, 1995)
At the request of the Energy Management and Operations Department at M.D. Anderson Cancer Center, the Energy Systems Laboratory of Texas A&M University performed a study of optimizing the HVAC operation at its Basic Research ...
Report of Energy Efficiency Study and Metering/Utilities Profile for Electric Deregulation at Tarleton State University (TSU), Stephenville, Texas
(Energy Systems Laboratory (http://esl.tamu.edu), Texas A&M University, 1999)
The director of Energy Management & Controls and staff at Tarleton State University (TSU) do a very good job of maintaining TSU and keeping expenses down. They have metering installed in many buildings and track the campus ...
Design And Retrofit Of A Low Solidity Diffuser For A Pipeline Centrifugal Gas Compressor Application.
(Texas A&M University. Turbomachinery Laboratories, 1997)
A high efficiency, single-stage pipeline centrifugal gas
compressor, originally designed with a wedge-type vaned diffuser,
was retrofitted with a vaneless diffuser along with two low solidity
diffuser configurations in ...
Application Of A Heat Barrier Sleeve To Prevent Synchronous Rotor Instability.
(Texas A&M University. Turbomachinery Laboratories, 1998)
This paper explains how synchronous rotor instability can occur
in high speed turbomachinery due to differential heating of bearing
journals. Theoretical investigations have indicated that rotors
supported by fluid-film ...
Turbine Instability Solution-Honeycomb Seals.
(Texas A&M University. Turbomachinery Laboratories, 1996)
A 40,000 hp steam turbine-generator in a utility service experienced a history of high vibration alarms and trips from an online vibration monitoring system. The excursions of high vibration restricted the operational load ...
The Design, Application, And Operation Of High Efficiency Turboexpanders In Process Plants.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Turboexpander thermal efficiency is an important parameter in the process design of hydrogen purification plants. When a process requires low flow and high head, expander thermal efficiency can only be improved by increasing ...
Vibration Reduction Or Large Steam Turbine Generator Through Bearing Analysis/Modification.
(Texas A&M University. Turbomachinery Laboratories, 1997)
Large utility steam turbines have experienced very high vibration levels on their generator exciter bearings. Units where the exciter rotor is supported by a single bearing are particularly susceptible. This synchronous ...
Discovering, The Hard Way, How A High Performance Coupling Influenced The Critical Speeds And Bearing Loading Of An Overhung Radial Compressor - A Case History.
(Texas A&M University. Turbomachinery Laboratories, 1997)
A case is presented where significant unacceptable vibration levels were encountered during mechanical testing of a single stage overhung radial compressor used in a mechanical vapor recompression process. The contract ...
High Speed Oil-Free Turbomachinery String.
(Texas A&M University. Turbomachinery Laboratories, 1998)
This paper is a discussion of the design, manufacture, test, and
field operation of a totally oil-free string of rotating equipment. The
turbomachinery string consists of a multistage centrifugal
compressor driven by a ...
