Evaporator Coil for Clothes Dryer

Evaporator Coil for Clothes Dryer

The evaporator coil in a clothes dryer is the key component responsible for removing moisture during the drying process.

Function

Dehumidification: The evaporator coil uses the phase change of refrigerant to absorb moisture from the air and reduce the humidity inside the dryer.

Heat exchange: During the drying process, hot air passes through the evaporator coil and moisture is extracted to help dry the clothes.

Working Principle

Air Movement:

A fan inside the dryer draws in air and directs it through the evaporator coil.

Refrigerant Circulation:

The inside of the evaporator coil is filled with refrigerant, which evaporates and absorbs heat at low pressure to form cold air.

The wet air is cooled and the moisture condenses on the surface of the coil.

Moisture Removal:

Condensed moisture is discharged through a drain or stored in a water tank.

Design Considerations

Material: usually made of aluminium or copper to improve heat transfer efficiency and corrosion resistance.

Piping Layout: Reasonable design of the coil layout to ensure that air can flow through evenly and improve moisture removal efficiency.

Cleaning and Maintenance: Regularly clean the evaporator coil to prevent the accumulation of dust and dirt from affecting the heat exchange efficiency.

Troubleshooting

Frosting: If the evaporator coil is frosted, there may be poor air flow or insufficient refrigerant.

Poor water discharge: Check whether the drain pipe is blocked to ensure that water can be discharged smoothly.
