Energy Saving Tips for Freezers

06 March 2017

Freezers are energy gluttons when they operate inefficiently. They work around-the-clock, so they painfully exaggerate those power consumption figures. The 24/7 refrigeration cycle is as it should be, of course, for there are perishable commodities stored inside the insulated cabinets. Inefficient workings, however, are not welcome in freezer equipment. Here are some useful energy saving tips for restoring workload balance to your freezer.

Operational Transgressions 

Kitchen workers needs access to refrigerated food, but there’s really no excuse for keeping that insulation-critical seal broken for several minutes at a time. Incautiously opened freezer entryways account for around six percent of a freezer’s total energy losses.

Entryway Addendums 

There are rare instances where an insulated chamber’s door must be kept open. Sliding doors in a meat packing facility open their seals to allow pallet jacks and forklift trucks access to frozen joints of meat. In this case, plastic-lined door curtains should be fitted to the entryway as an energy barrier. Similar barriers are available for man-sized freezer doors. Install them if increased foot traffic compromises the seal.

Educate Personnel 

Instead of creating a piecemeal power saving strategy, coordinate the effort by establishing a smart energy saving plan. Train everyone to follow this plan. This approach may take more time, but it pays off in the end. Freezer logistics is one example of this energy management strategy in motion. Trained catering workers draw on this logistics knowledge to fill one walk-in unit to capacity while a backup is left inactive until it’s required.

Scheduled Maintenance 

Dirty refrigeration coils block system airflow. Elsewhere, a poorly aligned thermostat sensor sends false readings back to a controller. Correct these issues by scheduling a maintenance plan. Significant energy savings are recovered when the refrigeration gear is periodically cleaned and tuned.

Become an Airflow Manager

The plastic coated shelves used in walk-in freezers aren’t there for decoration. The design maximises airflow so that chilly air reaches every corner of the freezer chamber. In service of this goal, adopt a commodities storage plan that improves air circulation. Distribute containers evenly, then purchase shelves and tables that act in accordance with this layout policy.

Pages of tips are required to save energy in a hardworking freezer, but they’re easily condensed into a single sheet of paper when an energy management plan is taught. Other than this training, always use Energy Star approved equipment, and protect that rating by initiating a first-rate maintenance program.
