SketchUp ModelsSo far, we have not used these models but if you are curious about how coils are built or how a water coil might differ from a distributing tube steam coil, then you may find them helpful since you can electronically take the coils apart by turning layers on and off.
There are also models from a case study of an air handling system with very poor discharge conditions that contrast as designed with as installed conditions along with perfection and the best possible field solution. I have also not used these yet but the topic may still come up. Usually, when we have more time, I use these models as an example of something a control system can not fix directly. But, by optimizing things like the schedule and the air side flow profile (the system was a VAV system) it is possible for the control system to minimize the impact of the poor discharge conditions. There is information on the SketchUp page of this website about how to get a copy of the free version of SketchUp. All of the models have been back-saved to SketchUp version 8 in case you already have an older version of SketchUp on your computer. If you have a newer version, the files will also open in any version of SketchUp from version 8 forward. 
Supporting InformationThis zip file contains all of the spreadsheets and system diagram I used during out discussion. The software tool that I used to estimate heat loss from a pipe was 3EPlus, which is a free download from the NAIMA website.

The zip file below contains the follow-up materials I said I would provide during lecture on Wednesday. It includes the two articles that Jerry Williams wrote for Heating, Piping, and Air Conditioning magazine about fan heat and the spreadsheet I used to calculate the source energy required to charge an iPhone.
If you want to know a bit more about site vs. source energy and be linked up with some resources that will give you access to conversion factors, you may find the blog post I did titled Site vs. Source Energy to be of interest.

The links and zip file below will connect you with the follow up materials I mentioned that I would provide during class on Thursday.
SketchUp Models You will always find the most current version of the chiller plant along with the site it is located on and the ballroom air handling unit it serves on the Chilled Water Plant System Diagram Exercise page of the website since they are the models behind that exercise. I have put anything yet on the website that uses the Heat Recovery Unit model or the Le Conte Annex AHU model, but you will find the HRU model in the materials I provided as a follow up for the Monday session of the class above. The Le Conte Annex AHU model is included in the zip file below. |

SketchUp Models and Supporting InformationThe models and materials I used today for this class are identical to the materials I used for the class last month at NAVFAC SW. So if you want them, just download the files from NAVFAC SW for Monday, October 23.
Depending on where are discussions take us today, there may be some materials that I use during lecture that are not in the downloads from NAVFAC SW. If that is the case, I will post a follow-up folder here this evening or tomorrow morning with that information in it. |

Followup InformationThe file below contains information I said I would provide during lecture on Monday, Tuesday, and Wednesday. It includes a "Read Me" file describing what the other files are.

After a bit of a delay, I have finally pulled together the stuff I said I would provide in during lecture on Thursday. The zip file below includes a 'Read Me" file describing what the other files are.

These are some models of coils and of an air handling system that had very poor system effect that complement some of the supplemental information that is provided on the equipment we are controlling; i.e. the controlled system.
If there are follow-up items that come up in class today, I will also add a folder here with that information in it after class. |

These are the files I will reference and use to support the exercise we will do where we think through a very basic control process and how you start to define the elements of the process (the inputs, outputs, set points, and the process itself) by taking the characteristics of the equipment you are controlling into consideration.
If there is follow up material from our discussion, I will also post that in a follow-up folder here after class. |

These files are the models and materials we used in class on Wednesday to supplement the slide sets. Note that because our timing shifted a bit, some of them were actually used on Thursday, but I had them grouped with the Wednesday information so I just uploaded them that way. The supplemental information file includes a Read Me file that describes what the different folders and files contain.

We have been using SketchUp models of mechanical equipment and mechanical equipment rooms as a teaching aid for a number of years now. The zip file to the left below the image contains a number of models that we typically use through-out the course of the class.
We will probably be using one or more of them on Monday. And, while you will be fine simply following along as we project them, without having them on your laptop, some people prefer to have them available during class. | ||
