Physics in refrigeration - Change of state
The Big Idea
This exhibition will be based around physics principle as used in refrigeration.
We take water for granted. Even some of the basic technology based items around the home, that makes up for creature comfort did not exist until the early 20th century - Yes, fridges and freezers that we take for granted is still a luxary for million of people in the underdeveloped countries.
The exhibit will be based around the principle of refrigeration - Compressor, evaporator, metering device, condensor and refrigerant.
These four areas will have their functionility explained, including the physics behind each of the functional area. The attendees will select premarked labels and accurately place the labels through a set of logic gates causing the whole thing to turn on as a functioning refrigerator. The unit can also be made to produce an alarm system if the logic was incorrect due to placing of inaccurate labelling resulting in incorrect logic.
