The refrigeration cycle typically repeats continuously as long as the refrigeration system is operating. The cycle consists of four main processes: compression, condensation, expansion, and evaporation. Here's a brief overview of the cycle:
Compression: The cycle starts with a compressor that compresses the refrigerant vapor, raising its pressure and temperature.
Condensation: The high-pressure, high-temperature refrigerant then flows into the condenser, where it releases heat to the surroundings and condenses into a high-pressure liquid.
Expansion: The high-pressure liquid refrigerant passes through an expansion valve or throttle valve, which reduces its pressure and temperature.
Evaporation: The low-pressure liquid refrigerant enters the evaporator, where it absorbs heat from the surrounding environment (such as the contents of a refrigerator) and evaporates into a low-pressure vapor.
After the evaporation stage, the refrigerant returns to the compressor, and the cycle repeats. This continuous repetition allows the refrigeration system to maintain a cool temperature by removing heat from the desired area and releasing it elsewhere.
It's important to note that the cycle repeats as long as the refrigeration system remains operational, which typically requires a power supply, proper functioning of components, and adequate refrigerant levels.
