What is Freon and what role does it play in a refrigerator?
Freon is a brand name for a group of refrigerants commonly used in refrigeration and air conditioning systems. These chemicals are essential for absorbing heat from the interior of the refrigerator and releasing it outside, thus maintaining a cool temperature inside the appliance. Without sufficient Freon, the refrigerator would struggle to cool effectively, leading to spoiled food and increased energy consumption.
Freon operates through a continuous cycle of evaporation and condensation. When the compressor compresses the Freon gas, it transforms it into a high-pressure liquid, which then moves through the condenser coils where it releases heat. When it reaches the evaporator coils inside the refrigerator, it evaporates, absorbing heat from the interior, thus cooling the space. Therefore, maintaining the proper level of Freon is crucial for efficient refrigerator operation.
