👉 Fridge fluid, also known as refrigerant, is a specialized liquid used in refrigeration systems to transfer heat efficiently. It circulates through the system, absorbing heat from the interior of the fridge and releasing it outside, thereby maintaining a cool environment. Composed primarily of chlorofluorocarbons (CFCs) or hydrofluorocarbons (HFCs), this fluid has a low boiling point, allowing it to vaporize at low temperatures and condense back into a liquid when needed. This cycle of evaporation and condensation is crucial for the continuous operation of the fridge, ensuring that it maintains the desired low temperature to keep food fresh and safe.
