WebFeb 20, 2024 · Look for any system where the primary methods of transferring energy are heat and work. Heat engines, heat pumps, refrigerators, and air conditioners are examples of such systems. Identify the system of interest and draw a labeled diagram of the system showing energy flow. WebIn the simulation of refrigeration and air conditioning systems, many refrigerant thermodynamic properties need to be converted to each other. Even a very little deviation in a single conversion process will lead to a large difference in the final calculated results because of a large number of iterations required. (4) Continuity and smooth.
