Work Night 3.22.18 on Desalination Machine

Date: 3.23.18
Time: 4:30-7:00 PM
Location: Logan HS
Time: 2.5 hours
Goal: Put new wheels on Desalination Machine and work on the chiller side of the cooling system.
Students: Dom, Austin, Ian, Caitlin, Cashew, Gabe, Matt, Boy Yang and Joel.

It was one of those nights were our testing revealed more failures than successes. The new wheels on the cart were mounted with no problems and work well. They are bigger wheels that will support the weight of the DM over uneven surfaces better.

Work began on the "cold" side of the DM tank. We wanted to use two PC radiators in the 8" pipe to cool the warm vapor that will be transferred from the hot tank. After looking at multiple variations, we found we could not get both radiators in the pipe at the angles we needed to support the best cooling in order to get condensation to occur. There is not enough room to pipe water into two of them at the same time.

We then began to construct a single radiator solution which will work, but we are unsure if we can get the temperatures we want with just one. An idea is to supplement the 1 radiator by running additional tubing in the cold tank that the cooled water can run through. This would be supported by a plexiglass infastructure.

Next work night will be spent on fabricating this system for the cold tank side of the DM.

right angles in the space we had to work with in using two radiators.

Here you see one of the radiators we are using and some of the plexiglass and support structures
we were experimenting with. We decided to use plexiglass as opposed to aluminum on the clean  (cold) water tank.
