What is the evaporator in a refrigeration system?

The evaporator in a refrigeration system is a key component where the refrigerant absorbs heat from the surrounding environment, causing it to evaporate from a liquid to a gas. This process cools the air or fluid passing over the evaporator coils, effectively lowering the temperature of the space being refrigerated. The gaseous refrigerant then flows to the compressor, where it is compressed and cycled back into the system. Overall, the evaporator plays a crucial role in the heat exchange process in refrigeration systems.
