How Does a Commercial Refrigerator Work?

Understanding how a commercial refrigerator operates is essential for businesses seeking to maximise the efficiency and reliability of their refrigeration systems. Liquid Sky Projects is committed to equipping our clients with the necessary knowledge to make informed decisions about their refrigeration infrastructure. Let’s delve into the inner workings of a commercial refrigerator to uncover the science behind its functionality.

At the heart of every commercial refrigerator lies a refrigeration system comprising several key components that work together to maintain optimal temperature and humidity levels. The primary principle governing refrigeration is the transfer of heat from the fridge’s interior to the external environment, thereby cooling the stored items. This process relies on the circulation of a refrigerant—a substance capable of absorbing and releasing heat—as it travels through various stages within the refrigeration system.

The refrigeration cycle begins with the compressor, which serves as the “heart” of the system. The compressor’s primary function is to compress the refrigerant gas, increasing its pressure and temperature. The compressor then pumps this pressurised gas into the condenser coils, which are either on the exterior or interior of the refrigerator. As the hot refrigerant gas flows through the condenser coils, it releases heat to the surrounding air or a coolant, causing it to condense into a high-pressure liquid.

Next, the expansion valve rapidly reduces the high-pressure liquid refrigerant’s pressure. This sudden pressure drop causes the refrigerant to evaporate into a low-pressure gas, absorbing heat from the refrigerator’s interior in the process. As the refrigerant gas absorbs heat, it cools the air inside the refrigerator, maintaining the desired temperature.

The cooled refrigerant gas then travels back to the compressor, where the cycle begins anew. This continuous process of compression, condensation, expansion, and evaporation ensures that the interior of the refrigerator remains consistently cool, preserving the freshness and quality of the stored items.

In addition to the core refrigeration components, commercial refrigerators may also feature other elements such as evaporator fans, temperature sensors, and defrost systems, all of which play a crucial role in maintaining optimal performance and efficiency.

By understanding the mechanics of how a commercial refrigerator works, businesses can identify potential issues, optimise energy consumption, and implement preventive maintenance measures to extend the lifespan of their refrigeration systems. At Liquid Sky Projects, we offer comprehensive refrigeration solutions tailored to your business needs, from installation and maintenance to repairs and upgrades.
