Basic Thermodynamic Processes

The word 'thermodynamics' can be divided into two words, 'thermo' and 'dynamics'. The word thermo deals with the heat and thermal phenomenon, whereas dynamics deals with forces or external agent that drives the heat flow or aids in the motion of heat.

Thermodynamics studies the relationship between temperature, energy, and work, and describes how energy changes from one form to another. A refrigeration cycle is a practical example of the application of thermodynamics. It is based on thermodynamic principles, such as energy conservation and heat transfer from a higher temperature region to a lower temperature region. The most common refrigeration cycle is the steam evolution cycle. It involves four main steps: upgrades, condensing, expanding, and evaporating.The study and understanding of thermodynamics are essential for designing efficient refrigeration systems, improving energy efficiency and understanding the behavior of refrigeration systems under different operating conditions. 2nd Step: Evaluate the performance of Refrigerator 2.Refrigerator 2 is a refrigerator that operates as an ideal vapor refrigeration cycle, and uses the same refrigerant fluid and the same evaporation and condensation temperatures as Refrigerator 1.In…
