Operating tips—walk-in refrigeration

Follow these best practices for even more energy savings.

Read the owner’s manual.
It will provide model-specific tips for optimum efficiency.

Check the insulation.
Regularly inspect the unit’s insulation and replace it when necessary.

Set and confirm optimum temperatures.
Regularly check the room’s temperature and adjust thermostats accordingly.

Use energy-efficient fans and pumps.
Fit these components with variable speed drives and run only when necessary.

Cut back on lighting.
Replace existing fixtures with energy efficient alternatives and turn off lights whenever possible.

Keep outdoor cooling coils shaded.
Direct sunlight can overheat the coils, reducing efficiency and even causing mechanical failure.

Clean the condenser coils and fan regularly.
Accumulated dust and debris can restrict airflow, causing the motor to work harder and use more energy. Ensure that the condensation drain is not blocked.

Open doors only briefly.
Cold air spills out quickly, forcing the cooling system to work harder to achieve the desired temperature. Restrict personnel and machinery operating inside the unit.

Install a strip curtain and automatic door closers on high-traffic units.
These features help reduce heat loads that can overwork the compressor.

Let food and containers cool before putting them inside.
Avoid adding unnecessary heat to the fridge or freezer compartments.

Keep door seals clean and tight.
If a sheet of paper placed in the door slides around or slips out, or if light from a flashlight placed inside can be seen through the seals, replace the seals. (Use the flashlight test on oven doors, too.)

Conserve water with a cooling tower.
This component pumps warm water from a water-cooled condenser through spray nozzles onto the tower fill material. As the water evaporates, it assists in cooling the condenser, meaning that the unit uses less municipal water.
