Define one cycle of refrigeration with thermodynamic processes?

Question

Accepted Answer

Refrigeration cycle involves four thermodynamic processes: compression, condensation, expansion, and evaporation.

The refrigerant is compressed by a compressor, increasing its temperature and pressure.
The high-pressure refrigerant then flows through a condenser, where it releases heat and condenses into a liquid.
The liquid refrigerant then passes through an expansion valve, where it undergoes a pressure drop and becomes a low-pressure liquid.
The low-pressure liquid refrigerant then enters an evaporator, where it absorbs heat and evaporates into a low-pressure gas.
The low-pressure gas refrigerant then returns to the compressor to start the cycle again.
Examples of refrigerants include R-134a, R-410A, and ammonia.
The refrigeration cycle is used in air conditioning systems, refrigerators, and industrial cooling processes.
