What Is A Commercial Refrigeration System?

If you’re managing a restaurant or a grocery store, you know you can’t afford any downtime for your commercial refrigeration system.

Walk-in coolers and freezers involve various moving parts that need maintenance. That is why, in this blog, there is a list of everything that you need to know about commercial refrigeration.

What is Commercial Refrigeration?

Commercial refrigeration refers to the cold storage equipment used in the retail setting. 

For example, reach-in refrigerators and freezers are found in supermarkets, food stores, convenience stores, and grocery stores.

The walk-in refrigerators and freezers in the restaurant equipment and cafes will also be considered commercial refrigeration equipment.

Refrigeration has allowed businesses to store foods and beverages for an extended period without getting spoiled. Commercial refrigeration keeps the prepared food and meal ingredients cold by subtracting heat for convenience and safety.

What are Different Types of Commercial Refrigeration Equipments?

There are various ranges of commercial refrigeration equipment which we recommend:

  • Reach-in vertical cases and refrigerators
  • Plugged-in enclosed vending machine
  • Semi-vertical display cabinets
  • Horizontal cases
  • Deli cases
  • Drop-in cases
  • Draft beer systems
  • Undercounter Refrigerators
  • Back door coolers
  • Refrigerated display cases
  • Prep tables

Let’s dive into the functionality of the types of commercial refrigeration equipment.

  • Coolers: Coolers keep items like food and beverages below the average room temperature yet above freezing.
  • Freezers: Freezers keep perishable items completely frozen, preventing them from spoilage.
  • Combination Coolers and Freezers:  Combination coolers and freezer units allow for chilling and freezing of perishable items.

Which of the Industries Need Commercial Refrigeration?

Various commercial refrigeration companies rely on commercial refrigeration. We categorize food and beverage firms, supermarkets, and convenience stores as businesses that require commercial refrigeration systems.

Hospitals and Medical research clinics use commercial refrigeration to keep sensitive items appropriately. You shall also find commercial refrigeration systems in the florist shops, where they can store fresh-cut flowers from the wilting.

Whether using commercial refrigeration to store food and drink, flowers, or even medical equipment, you should become familiar with how the equipment works. 

How Does Commercial Refrigeration Works?

  • Cooling Process: All of the refrigeration systems work according to the principle of the Second Law of Thermodynamics. This principle states that the heat will always travel from the warmer object to the colder one when two things of different temperatures come close together. So, commercial refrigeration systems utilize a refrigerant solution to transfer the heat from the food inside the refrigeration unit’s storage area to the refrigerant.


  • The Refrigerant: Refrigerant is the key to the success of modern commercial refrigeration systems. Earlier, Feron was the most common refrigerant found in air conditioning units and refrigerators. However, Feron was found to damage the earth’s ozone layer causing an increase in solar radiation reaching the planet’s surface and changing the global climate.

Today, the commercial refrigeration system has expanded into a vast industry. The chilling process can be high-temperature to get the environment to low-temperature freezing.

Storing Food & Beverages:

Freezers hold the fundamental vitality in the food business. If your refrigeration system does not work correctly, this could put your whole commercial refrigeration companies in jeopardy.

Commercial refrigeration challenges the owners, technicians, and installers who deal with them regularly. You might need a fresh industrial freezer installation, which includes networks, parts, and more.

What Role Do Compressors Play In Commercial Refrigeration?

A commercial plays a vital role in commercial coolers. Let’s see how a compressor works.

  • How do Compressors Work?

The power comes from the electric motor fixed in the system. This process eases the pressure on the refrigerant system. First, the refrigerant flows from the compressor via a condenser. This process happens in the condenser, where vapor converts into liquid and radiates heat. In air-cooled process chillers, moisture increases higher than the air going through the condenser. In a water-cooled process refrigerant systems, the refrigerant vapor passes through a higher temperature than the water going through the condenser. Whether you run a restaurant or a school, you know how crucial it is to keep your commercial cooler in good working condition.

5 Signs That You Need Commercial Refrigeration Repair

You can’t afford downtime because commercial refrigerators are essential appliances, especially at convenience stores, restaurants, and liquor stores.

Businesses depend on the efficiency of a quality refrigerator. Using a quality commercial refrigerator does not give you a tough time with regular maintenance since it has an extensive lifespan.

When your commercial refrigerator wears out, some signs show you need a new industrial freezer installation. Let’s see the signs below.

  • Excessive Condensation: All efficient commercial refrigerators work efficiently to maintain an excellent balance between the hot and cold atmosphere of the fridge.

In case of malfunctioning, you will likely see condensation mildew on the rubber sealing on your refrigerator door. In case of mild condensation on the rubber sealing, replace the worn-out rubber sealings in your way, and then the fridge is ready.

  1. Serve Motor Defects: Motor breakdowns are another significant sign that you must quickly replace your commercial refrigerator. Most refrigerator issues begin with motor failures. When you place your hand at the back of the refrigerator, it is a common experience that you might feel a regular warm temperature.


Now you know what a commercial refrigerator is, how it works, and what defects it might have.
