University of Wisconsin DDC Systems Class

The following links will let you download materials like SketchUp Models, spreadsheets and other supplemental materials that we may use in class to illustrate a point or for an interactive exercises.   I will also post any materials we develop or reference during the class each day after class in a follow-up folder for the day.

Note that these links are for the most recent/current class.  For previous class materials, visit the University of Wisconsin DDC Systems Class Archive Page.

Revised Slides

These are copies of the slides that I actually used in class today, which have some differences from the slides that were included on your CD.  The follow-up file contains the logic diagram we developed together in class along with some other information that came up in discussion with various people on breaks.

Bureaucratic Affairs Building Exercise

The interactive exercise we did is built around the imaginary Bureaucratic Affairs Building on the Center of the State University campus (COStU) in Golden Girl Missouri.   

The basic files you need if you want to revisit the exercise in depth and try your hand directly at adding the logic enhancements we discussed can be found on the Bureaucratic Affairs Building Heating Hot Water System Logic Modification Exercise page of the web site along with a general over-view of the exercise.  There is also a blog post that will connect you with additional control system design resources and help you get up to speed using SketchUp via an "Easter egg hunt" exercise you can do in the Bureaucratic Affairs Building model.

If you want a clean version of the logic diagram tool, you will find the current version of it on the Logic Diagram Tool page of the website along with the PowerPoint file that defines the symbols and illustrates how they are to be applied.

The answers to the exercise are at this link and include:
  • A copy of the logic diagram tool with the enhancements added to the basic logic we were looking at.
  • A copy of the logic diagram tool with additional logic associated with the hot water system including the building occupancy control logic and the hot water pump control logic.
  • The narrative sequence with the additional enhancements added.
  • The point list with the additional points required by the revised logic added.

These are copies of the slides that I actually used in class today, which have some differences from the slides that were included on your CD.  The follow-up file contains the logic diagram we developed together in class along with some other information that came up in discussion with various people on breaks.

The tab-04.72 is the actual PowerPoint file for the .pdf you have in your class handouts.  It is supplemental information that I typically don't present formally but have on hand in case questions come up.  The benefit to having the PowerPoint is that if you run it as a slide show, it will animate the operation of a one pipe and two pipe pneumatic controller vs. paging through the slides one by one, which what you have to do with the .pdf file.   You will also find a number of other pneumatic control system resources on the Pneumatic Control Resources page of the website.

The zipfiles to the left contain the models we will use in class today.  I also uploaded the energy recovery unit model we used yesterday to discuss linkage system kinematics.

The files to the left are an older Siemens PPCL manual, which will give you a sense of what a line code based programming language looks like.  You could contrast this with the graphic programming language ALC uses if you download Eikon for Educators and work with it.

Jay's discussion about measuring outdoor air temperature reminded me that the World Meteorological Organization publishes a guideline regarding how to site sensors that are going to be used to measure  meteorological data such as outdoor air temperature and humidity, wind speed and direction, etc.   The file to the left is a copy of that guideline and will give you some insight into what you would need to do if you really wanted to do it right.   There is also a book titled The Weather Observer's Handbook that provides a lot of useful information on the topic.
This morning we had a discussion about how to control one-third/two-third valve arrangements.  I added the magazine article I mentioned along with the Moore control engineering application bulletin to the Magazine Articles page of the website so you can access it from that location.

In a discussion yesterday afternoon about stratification in economizer plenums, I showed you a video that Jay Tulley put together for me using data from a data logger array we had deployed in the mixed air plenum of an air handling system down in Monterey, California.  I have posted that video along with the background information about the air handling unit behind the data and some other stratification information on the video page of the website so you can access it there.

Finally, the zip file to the left contains additional follow-up information that either came up in the lectures Thursday late morning and afternoon or highlights a couple of optional case studies that we did not have time to do but which you an probably follow if you want simply by reviewing the slides and the supporting information.   There are READ ME files included to describe what each of the folders and files in the zip file are about.
