The failure of a refrigeration system in a refrigerated dryer can lead to several issues, such as:

Inability to maintain the required dew point: The refrigeration system in a refrigerated dryer is responsible for cooling the compressed air and removing the moisture from it. If the refrigeration system fails, the compressed air will not be cooled sufficiently, resulting in an inability to maintain the required dew point.

Increased energy consumption: When the refrigeration system fails, the compressor will have to work harder to compensate for the loss of cooling capacity. This can lead to increased energy consumption, which will result in higher operating costs.

Damage to downstream equipment: Moisture in compressed air can cause damage to downstream equipment, such as valves, instruments, and tools. If the refrigeration system fails, the compressed air may contain more moisture than usual, which can increase the risk of damage to downstream equipment.

Increased maintenance costs: If the refrigeration system fails, it may result in increased maintenance costs to repair or replace the system. This can cause downtime and lost production, resulting in lost revenue.

In summary, the failure of a refrigeration system in a refrigerated dryer can have significant consequences for the performance, energy efficiency, and maintenance costs of the system, as well as downstream equipment. Regular maintenance and monitoring of the refrigeration system can help prevent such failures and ensure the proper functioning of the dryer.
