August 5-9

August 5 – The write up was not detailed enough to be given to the person who will be installing the chilled water line. I was also told that we will not be able to connect the pump in series. I therefore need to make major changes to the model I have made. I spent my time making these changes. I also downloaded AUTOCAD in order to edit Jim’s initial drawing of the setup instead of editing it in Paint or Powerpoint.

August 7 and 8 Today Ann Marie and I worked on a few models. It is now overwhelmingly clear that this project was more complicated than previously expected. We drew the setup and made copies of it in order to mark them up with different values for flow rate, pipe diameter, etc. We spent some time trying to find out the temperature of the chilled water line, as this is important to the amount of heat the exchanger can take out. I measured the temperature of the tap water as an estimate; I imagine the chilled water line will be cooler.
