What is The Most Commonly Used Commercial Refrigeration System?

The refrigeration system plays a crucial role in our day-to-day lives, preserving food, keeping spaces cool, and supporting various industries. Amongst the dynamics of technologies available, the most commonly used commercial kitchen repair service is the Vapor Compression Refrigeration System.

In this blog, we will dive into the workings of this unique system, understand its process, and explain why it has become the backbone of refrigeration and cooling technology. Let’s get started.

A refrigeration system is a group of components used for cooling and sometimes heating. It involves the use of a thermodynamic cycle in which there is a flow of heat from one place to another. It is a system that can cool and maintain temperature within a given range.

Understanding Vapor Compression Refrigeration System

The Vapor Compression Refrigeration System functions on a fundamental thermodynamic principle: the phase change of a refrigerant. This system is the soul of most commercial kitchen repair, air conditioners, and cooling units. It consists of four main elements, namely: Compressor, Condenser, Expansion Value, and Evaporator.

  • Compressor: The compressor is the heart and soul of your refrigeration system. It is an air pump that compresses refrigerant gas and changes its state, which allows it to absorb heat. This process results in cooling, which is then distributed to your facility via the air ducts.

Your refrigerator’s compressor works by drawing in warm air from the inside of the fridge and pumping it through coils in the condenser. The coils are located outside the unit, generally on top of the refrigerator. The air passes over these coils, which cools it down so that it can be re-circulated into the fridge and keep your products cold.

  • Condenser: The condenser is part of a refrigeration system that removes heat from the refrigerant. It is an air-cooled device, so it must be mounted where air circulation is good.

The condenser contains tubes and fins that absorb the heat from the refrigerant flowing through it, causing the refrigerant to evaporate london catering repairs. The vapors are then carried back to the compressor, where they are compressed again and cooled, finishing the cycle.

The condenser coils in a residential air conditioning system which generally contains a refrigerant known as R-22, which was developed to use in these systems.

  • Expansion Device: The expansion device is a crucial part of a refrigeration system. It controls the flow of liquid refrigerants within the system. It helps in preventing overcharging and undercharging of your cooling system.

The sole motive of an expansion device is to regulate the amount of liquid refrigerant entering the evaporator coil. This helps keep the pressure in your system at its optimum level, which prevents unnecessary costs and repairs.

An expansion value consists of two parts: a cap and a body. The cap contains a diaphragm with a spring attached to it. The body is connected to the cap by two hoses, one for suction from the evaporator and one for the discharge to the condenser.

When the liquid refrigerant enters the expansion valve, it causes pressure on the spring-loaded diaphragm inside the cap. This pushes open one or more ports in the cap.

These allow refrigerant to pass via either suction or discharge lines depending upon whether the pressure is being increased or decreased.


The Vapor Compression System is the most commonly used refrigeration system due to its efficiency, versatility, and widespread applicability.
