Want to get better acquainted with the kitchen appliance that never takes a break? Learn about the main parts of a refrigerator, from the compressor to the evaporator coils, and discover what each part does.
The compressor is essentially an engine. Its job is to kickstart the entire cooling process. The compressor pumps the vapor refrigerant (the cooling agent) through the fridge by increasing the pressure and temperature of the coolant as it makes its way through the refrigeration cycle. Typically, you will find the compressor on the bottom or back of the refrigerator.
2. Condenser coils
The condenser coils, located on the back or bottom of your fridge, are the pipes where the vapor refrigerant condenses into liquid form as the compressor continues to increase pressure. As the condensation process occurs, the refrigerant releases heat that is then pushed out into the outside air. This heat is the air that you’ll typically feel coming out from under your fridge.
3. Expansion Device
The expansion device causes a rapid pressure reduction in the refrigerant, transforming it back to a vapor state. Located between the condenser and evaporator coils, its function is to control the release of pressure as the change of state from liquid to vapor occurs.
4. Evaporator coils
The evaporator coils are where the actual cooling of the refrigerator occurs. As the refrigerant passes through the coils, it absorbs any heat that is in the surrounding air, generally from the food compartment side of the refrigerator. As the coils absorb the heat, they release the cool air felt when opening the refrigerator door. Small vents on the inside of the freezer and refrigerator allow the air to move from the freezer and into the fridge. These coils are typically in a covered part in the back of the freezer.
keep air vents unobstructed
Keep your air vents clear from food items for maximum airflow throughout your refrigerator. Keeping your air vents unobstructed will also ensure that your food stays at optimal temperatures.
