An evaporator coil is one of the most important components of a HVAC systems and industrial, commercial and transportation refrigeration systems. Mainly they are used in close control air conditioners, rooftops, showcasing, fan coils, dryers and other systems. The high-quality cooling of the working environment depends on it, which means that it is largely responsible for the durability and wear resistance of the unit. And that is why a properly selected and manufactured evaporator is the basis of the correct operation of the entire system.
The function of the evaporator coil is to extract indoor heat from the air and transfer it to the refrigerant. A refrigerant runs through its copper tubing that removes heat from the air. Fins increase the overall surface area for heat exchange, thus drastically improves the heat conducting efficiency.
