Fabrication of Wind Chill Food Preservation Refrigeration System

Abstract

Our design concept aims to take on the problem of food stores spoiling in areas with poor access to electricity. The goals of our alternate food preservation unit are to not require an electricity grid, to be significantly less expensive than a modern refrigeration methods and to be able to be incorporated into the regions of poverty where it is most needed. The cooling mechanism is inspired by temperature regulation approaches seen in mammals and insects and is a new way of approaching issues in the food system.

In our process an intake structure passively draws in air warm ambient air and injects it via the venture effect it into a pipe. The second step delivers the air into the evaporation chamber, where the pipe is immersed in a fluid. The fluid evaporating from the around pipe cools the inside air and lastly the third step involves the cooled air entering the refrigeration chamber where food is stored.
