(Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2006)In this paper, we briefly introduce the super cold air distribution technique. By comparing the schemes of two air conditioning systems, including a modified air conditioning system, this paper analyzes the technique ...
-
(Energy Systems Laboratory (http://esl.tamu.edu), 1999-05)Speed variations of pumps have become increasingly popular as the technology to produce variable frequency drives has progressed. Variable speed drives have many advantages compared to throttle valves when it comes to ...
-
(Energy Systems Laboratory (http://esl.tamu.edu), 1997-04)Steam turbines have long been used at utilities and in industry to generate power. There are three basic types of steam turbines: condensing, letdown and extraction/condensing. • Letdown turbines reduce the pressure of ...
-
(Energy Systems Laboratory (http://esl.tamu.edu), 1996-04)Chilled Water Thermal Energy Storage (TES) offers benefits to both the electricity supplier and the electricity user. This well-established technology uses stratified chilled water to store energy in thermal form so that ...
-
(Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 1984)It seems that we have all struggled to convince management to pursue energy conservation using economic arguments, only to find that when all is said and done there is something else that gets certain projects approved. ...
-
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1987-09)The performance of heat integration systems is normally quantified in terms of the amount of heat that is recovered. In an effort to mitigate the usual decrease in heat recovery with time due to fouling of the heat ...
-
(Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 1982)Recently, back-pressure steam turbines have become the focal point in many cogeneration applications. This is a result of the savings in operating costs associated with the generation of electrical or mechanical power ...
-
(Energy Systems Laboratory (http://esl.tamu.edu), 1985-05)The design and choice of a specific cogeneration system is a process of selecting and deciding from numerous alternatives, including the option not to cogenerate. The final system specification is in reality the result of ...
-
(Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 1983)The economics of four concentration processes utilized by the food industry were analyzed. The processes examined are: triple effect evaporation, mechanical vapor recompression evaporation, reverse osmosis, and freeze ...
-
(Energy Systems Laboratory (http://esl.tamu.edu), 1994-04)Three new factors are coming together to motivate gas pipeline firms to consider electric motors for replacement of older reciprocating gas engines for compressor systems, and for new compressor installations. These factors ...
-
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1987-09)Capital allocated to energy savings projects competes with that for new or revised plants. Thus, it must show the same or better rate of return. Usually the risk factor in energy savings projects is less than allocations ...
-
(Energy Systems Laboratory (http://esl.tamu.edu), 1979)Over the past 10 years energy costs at Union Carbide's Texas City Plant have risen tremendously. Most of this increase can be related to the rapid escalation in fuel prices. Because of the large cost increases and impact ...

-
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1988-09)This report determines the conditions needed for an Organic Rankine Cycle to be economically attractive to recover heat going to air fins or cooling water. It includes discussion of some installations, and the impact ...
-
(Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 1984)Oxygen enriched air combustion is a recognized approach to energy conservation. Conventional methods of producing oxygen enriched air: Pressure Swing Adsorption and Cryogenics, are energy-intensive and expensive. In this ...

(Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2011)Energy prices have exhibited significant volatility in recent years. For example, natural gas prices ranged from $4 to $15 per MM BTU's in calendar years 2005 through 2011. Future prices are uncertain but are likely to ...
-
(Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 1980)The economics of combining steam and electric generation for companies requiring both steam and electric services develop a challenge which few engineers and economists can realize. This paper outlines the general approach ...
-
(Energy Systems Laboratory (http://esl.tamu.edu), 1985-05)Economics of Steam Pressure Reduction is a technical paper that addresses the operating and economic advantages associated with the program to lower the steam operating pressure. Evaluation of a testing program will be ...
-
(Energy Systems Laboratory (http://esl.tamu.edu), 1985-05)To properly design a pipe heating system, the basic principles of heat transfer from an insulated pipe must be understood. The three methods of heat flow are conduction, convection (both forced and natural) and radiation. ...
