Role of Coolant in a Refrigerator

Coolant plays a crucial role in the cooling process of a refrigerator. It is responsible for extracting heat from the product inside the refrigerator.

In a refrigerator, the coolant, typically a refrigerant substance like Freon, circulates through the evaporator coils. As it passes through the evaporator, the coolant absorbs heat from the product inside the refrigerator, such as food or beverages.

Once the coolant absorbs the heat, it undergoes a phase change from liquid to gas. This phase change occurs at a low temperature, which helps keep the inside of the refrigerator cool.

After absorbing the heat from the product and cooling the interior of the refrigerator, the coolant then travels to the condenser coils located outside the refrigerator. Here, the heat absorbed by the coolant is released into the surrounding environment, allowing the coolant to condense back into a liquid form and restart the cooling cycle.

So, in summary, coolant in a refrigerator plays a vital role in extracting heat from the product and helping maintain a cool temperature inside the refrigerator.
