Introduction
OTW Engineering was tasked with designing an icemaker that is not only small enough to be packed in a car on a long drive or trip, but also design it so that it can be used in most hotel rooms utilizing the wall sockets, standard 110 volts electricity. The icemaker would need to be able to fill a 30cm x 30 cm x 30 cm ice cube reservoir from empty overnight. The icemaker should be designed utilizing inexpensive manufacturing methods and materials, yet provide the rigid structure and ice output required by the customer. In order to provide a detailed design, every component, for example the compressor, condenser, refrigerant, and the thermal material used as reservoir walls, must be designed/ specked to give us the most efficient ice maker possible.
History
The very earliest forms of refrigeration were simply the harvesting and storage of large blocks of ice from high altitudes and cold climates where it was prevalent. However this is a very labor intensive, arduous task. The trouble of what to do with excess of food supplies was finally solved in a practical means with the invention and wide spread adoption of vapor compression refrigeration systems. Since its inception, the main components have remained broadly unchanged in their basic design and function [1]. While many small improvements in efficiency and manufacturing have been made, the basic components of a refrigeration system are the following: A gas to be used as the
