You see them everywhere–the ubiquitous walk-in cooler or freezer. These refrigeration systems are an essential part of cafeterias, restaurants, hospitals and convenience stores but are a large source of energy consumption. They are also rarely considered until problems emerge.
Common problems include compressor failure and failure to maintain pressure, both of which can result in an expensive loss of the products they store. Just as you would expect from your HVAC equipment, these problems, as well as unnecessarily high energy use, can be avoided by observing equipment and taking corrective action.
PREVENTION WITH PROPER MAINTENANCE
Operations and maintenance issues should be addressed to avoid:
- Excessive energy use
- Costly repairs
- Downtime
- Potential product loss
Cooler Doors
Door gasket condition, door closure assist, and heater strip functionality are all potential sources of problems. Air leaks from torn gaskets around the door can cause excess water on the floor as well as higher humidity levels inside the cooler. This environment is a cause for concern in regards to safety issues and high energy demands.
Evaporators
Ideally, each evaporator has a built in defrost cycle to address built up ice on the coils; the resulting water is then drained from the freezer. Lack of maintenance can lead to water being allowed to seep into cracks, then freeze and expand.
Condensers
Condenser coils should also be checked regularly for cleanliness. Dust and debris will act like ice buildup on an evaporator coil. This will insulate the heat transfer surface and reduce airflow, which will make the compressor run harder and longer. In extreme cases, compressors may fail.
