The Carnot refrigerator is the maximum limit to the COP (efficiency) of a refrigerator system. Although we cannot make the carnot refrigerator, it tells us the maxium or best performance that can be garnered from a real refrigerator. The carnot refrigerator is sort of ideal in its design.
Introduction to Refrigeration. JoVE, Cambridge, MA, (2020). Principles. The vapor compression cycle is comprised of four main components: the vapor compressor, condenser (high-temperature heat rejection), expansion device, and evaporator (low-temperature heat acquisition) (Fig. 1). The cycle can be described with four key state points.
Interesting Facts about Refrigerators. Refrigeration and refrigerators changed the face of the Earth more that we probably know. They allowed us to feed healthier, to live in places we never had conditions for and to eat food we would never taste unless we travel to the place that it grows.
