How does a walk in cooler work?

When you have a walk in cooler in your restaurant or similar business, you have a sophisticated piece of equipment. Knowing how it works will help you recognize problems when you need walk in cooler repair.

Walk in coolers operate similarly to your HVAC system, and have many of the same parts such as compressors and condensers. One of the most important parts of your walk in cooler is the evaporator, because it freezes the moist air to manage heat transfer. If your evaporator coils are icing up, and not defrosting, you may have a problem with the system. 

Condensers remove heat from the cooler in a similar way they remove heat in an air conditioner. In this case, however, the condenser regulates temperatures to keep your frozen and perishable products at the right temperature. If dirt builds up on the coils or the fan gets damaged, you could have problems with your condenser. The compressor adds pressure to the refrigerant and compresses it into a gas so it can flow back into the condenser. Drops in temperature may indicate your compressor is malfunctioning.
