Which component in a refrigerator absorbs heat from inside the appliance?

The evaporator coil is the component in a refrigerator that absorbs heat from the inside of the appliance. This process is essential for maintaining the cool temperatures required for food preservation. When the refrigerant flows through the evaporator coil, it undergoes a phase change from a liquid to a gas. As it evaporates, it absorbs heat from the refrigerator's interior, effectively lowering the temperature inside the unit. This heat transfer is a fundamental principle of refrigeration, allowing the appliance to maintain its desired cooling effect.

The other components serve different functions in the refrigeration cycle. The condenser coil releases the absorbed heat to the outside environment, the expansion valve regulates the flow of refrigerant into the evaporator, and the compressor circulates the refrigerant throughout the system. Each component plays a critical role, but it is the evaporator coil that specifically targets the absorption of heat from within the refrigerator.
