How Do Commercial Refrigeration Systems Work?

As a business operator who relies on commercial refrigeration, it is imperative to ensure your systems are running correctly. After all, the purpose of commercial refrigeration systems is to keep your perishables cool and at a safe temperature for storage. A refrigeration system keeps food cool by removing heat from inside the unit and redirecting it elsewhere. That’s the basics of a commercial refrigeration system, but the process of cooling is quite complex. Read on.

The basics of commercial refrigeration systems

Much like your home refrigeration unit, commercial refrigeration systems use mechanics to remove heat away from a space and transfer it to another area. The removal of heat, therefore, lowers the temperature and creates a cool space. Parts and components are required to maintain a refrigerator’s cooling cycle.

A commercial refrigeration system’s main components are:

  • Refrigerant. The refrigerant is a liquid substance used in a refrigerator’s heat cycle. Without the refrigerant, your fridge will not cool. A commercial refrigeration system with an inadequate level of refrigerant will not reach the low temperatures required to keep your food cool.
  • Compressor. This is the heart of your refrigeration unit. The compressor circulates the refrigerant throughout the commercial refrigeration system. The compressor heats the refrigerant into a gas.
  • Condenser. At the back of your commercial refrigeration system sits the condenser. Inside the condenser, the refrigerant is cooled down and condenses, turning the substance from gas back to liquid.
  • Evaporator. The evaporator is the clever part of your commercial refrigeration system that keeps your food cold. As the refrigerant turns from liquid into gas, the evaporator cools the space inside your fridge to an adequate temperature in which to store your perishables.
  • Capillary Tube. The copper capillary tube is long in length but is coiled to fit into a smaller space. This tube acts as a throttling device. When the refrigerant leaves the condenser as gas, it moves into the capillary tube, which decreases the pressure quickly and the substance is directed into the evaporator.
  • Thermostat. The thermostat controls the cooling process of your commercial refrigeration system. This device monitors the temperature and switches the compressor on and off. It does this by sensing when it is cold enough inside the fridge, and switches off the compressor. When the thermostat registers too much heat, the compressor is switched back on to start the cooling process again.

The mechanics of your commercial refrigeration system

Refrigeration systems work by circulating the refrigerant inside the unit, altering the substance from liquid to gas. This works by an evaporation process, whereby the refrigerant substance is pushed through the capillary tube. This process of evaporation cools the area inside the refrigerator to the desired temperature.

To keep the system running, the refrigerant substance must be altered from gas back to liquid, and this is done via the compressor. As mentioned above, it is the thermostat’s job to monitor when the compressor must be switched on again to start the cooling process inside your commercial refrigeration system.

Don’t be left out in the cold with your commercial refrigeration system

Because of the complexity of a commercial refrigeration system, you should never attempt to fix a faulty unit yourself.

Likewise, because of the value a fully functional commercial refrigeration system has for your business, it is imperative to ensure your system is running well.
