Which component is responsible for heat exchange in refrigeration systems?

The component that is responsible for heat exchange in refrigeration systems is the evaporator and condenser coils. These coils play a crucial role in the refrigeration cycle by facilitating the transfer of heat through condensing and evaporating refrigerants.

In the evaporator, the refrigerant absorbs heat from the surrounding environment, typically the air or liquid being cooled. As the refrigerant evaporates, it changes from a liquid to a gas, absorbing heat in the process and reducing the temperature of the air or liquid. This is essential for cooling applications, as it effectively removes heat from the space being refrigerated.

In contrast, the condenser works in the opposite manner. Here, the refrigerant gas, which has absorbed heat in the evaporator, is compressed by the compressor and then sent to the condenser coils. In the condenser, the refrigerant releases the collected heat to the surrounding environment, allowing it to condense back into a liquid. The heat exchange process in both coils is fundamental to the refrigeration cycle, enabling continuous cooling.

The thermostat, compressor, and expansion valve all play supportive roles in the refrigeration system. The thermostat controls the temperature settings, the compressor circulates the refrigerant through the system by compressing the refrigerant gas, and the expansion valve regulates the flow of
