Commercial Refrigeration: What Restaurant Owners Need to Know


As a restaurant owner, you rely heavily on commercial refrigeration units. Although you don't have to be a refrigeration expert, there are some critical things you should know about refrigeration for restaurants in Philadelphia, PA. Knowing the basics of refrigeration maintenance will help you extend the lifetime of your commercial equipment. 


Don't Block Vents

The vents on refrigeration units serve very important roles. These vents are essential for the flow of air, which, in itself, is integral to the cooling process. If you block these vents with boxes, debris, or other items, the cooling process will lose efficiency.


Blocked vents can result in higher energy usage, loss of cooling power, and damaged refrigeration equipment.


Turn Off the Lights

Make it a regular habit to turn off the lights in walk-in refrigeration units. In addition to driving your energy costs higher, leaving the lights on inside a walk-in cooler or freezer will generate ambient heat. This will reduce the cooling power of your commercial refrigeration equipment.

Another good practice is to replace the standard incandescent bulbs in your walk-in refrigeration equipment with fluorescent bulbs. These bulbs use less energy and run cooler. They also last considerably longer, saving you money on the cost of replacement bulbs.


Perform Visual Inspections of the Equipment

Your refrigeration equipment requires a visual inspection at least once every 30 days. During the inspection, look for puncture marks and torn seals in the doors. Check the hinges, latches, and gaskets for rust or loose fittings. 


Any of these issues could lead to cold air leaking from the refrigeration equipment. In addition to wasting more energy, these damages can reduce the unit's cooling power. If you notice food is spoiling faster than it should, check for damages right away. A minor issue could cause a significant energy drain.
