Simulation Modeling of Central Chilled Water Systems-ASHRAE Chicago 2012 Conference (CH-12-003)

This technical paper on simulation modeling (CH-12-003) titled Simulation Modeling Of Central Chilled Water System, was published at the ASHRAE/Chicago Conference of January 2012 in the advanced technical session one. If you registered for the conference you can go to www.ashrae.org/chicagoOline and view about 30 slide power point presentation with recorded voice. I continue to work on the presentation therefore an expanded power point presentation is below for your review. The 10 upgrades address plant upgrades and building upgrades with upgrade 10 addressing a simulation model as part of the site control/monitor system.

Simulation Modeling of a Central Chilled Water Plant-ASHRAE Chicago 2012 (CH-12-002)

This paper (Ch-12-002) was published at the ASHRAE CHICAGO Conference of January 2012 in the advanced technical session 1 and can be purchased from ASHRAE. Attached is an expanded power point presentation, part of which was given in Chicago. If you registered for the conference you can go to www.ashrae.org/chicagoOline and view the reduced slide power point presentation with voice. Below is the expanded power point presentation, I continue to work on giving a better understanding of simulation modeling.

System Simulation Modeling–HPAC Engineering article of September 2011

A simulation model is a set of simutanious equations, solved by computer, that obeys the laws of thermodynamics and includes the part load performance of the chillers, towers and other equipment of the system. This is the fifth and final paper of this series published in HPAC Engineering September, 2011. The paper can be viewed at http://bit.ly/Nelson_5

 

Anatomy of Load Delta T–HPAC Engineering article of August 2011

Examining why low load delta T is so pervasive in central chilled water systems, published in HPAC Engineering August, 2011, “Anatomy of Load Delta T” and can be viewed at http://bit.ly/Nelson_4

Efficient Control of a Primary-Only Plant–HPAC Engineering article of July 2011

 A strategy for efficient control of a P-only plant that is experiencing low load delta T. 

This is the third article in a series of five on P/S vs. P-Only pumping that was published in HPAC Engineering on July 2011, “EFFICIENT CONTROL OF A PRIMARY-ONLY PLANT” can be viewed at (http://bit.ly/Nelson_3

Efficient Control of Primary/Secondary Plant–HPAC Engineering May 2011

A control strategy for operating a P/S plant when low load delta T exists. This article is the second in a series of five  published in HPAC Engineering May, 2011, title “Efficient Control of Primary/Secondary Plant” and can be viewed at http://bit.ly/Nelson_2

Primary/secondary vs. Primary-only Pumping–HPAC Engineering April 2011

This is the first article of five published in HPAC Engineering to deal with the characteristics of P/S vs. P-only distribution pumping in central chilled water plants. The analysis utilizes a plant simulation model that duplicates the performance of the real system as defined by manufactures data for chillers and towers.
