Testing

Throughout our testing there were many issues that we ran into. Our original idea was to attach the peltier plates to the back of the fans in order to provide a cooler air flow. However, we worked out that this would not provide enough cold air that we needed. After implementing other ideas like heatsinks and thermal pads we decided to turn to some research to help us. We found a module that was exactly what we were trying to build only with higher quality parts and better assembled.

As we recieved parts we began to test them to see if they worked, we tested both the peltier plate and the fans. The peltier plates seems to overheat and not provide cold air and only get really hot.

We tested this module by putting some water on the cooling plate. The plate actually got cold enough to the point where it froze the ice. After attaching it to our build we noticed that we needed a way to circulate the air. We decided to add two fans on the side in order to provide that air flow that we needed.

We built our model in a smaller version so we could see how it might run on a smaller scale. We hooked up all of our compenents and plugged it in and let it run for several hours. When we came back and tested the water bottle we put inside, we noticed it was a few degrees colder. This was a good start but we knew we ultimately needed to make some changes.

We let the model run for a bit and when we opened it we were able to notice a temperature drop between the outside air and the air inside the cooler. This was huge for us because we were able to finally say that our cooling system worked.

We tried to hook up our solar panel to our cooling system but the panel did not provide enough voltage to power all of the components of our design.
