How does a commercial Refrigerator work?

Every day we come across various appliances that make our lives easier, and one such essential appliance is a commercial refrigerator. But have you ever wondered how it works? Let's delve into the intricate process of the refrigeration cycle and understand its operation step by step.

Step 1: The Compression of the Refrigerant

The refrigeration cycle begins with the refrigerant being compressed. In this phase, the refrigerant, initially in a low-pressure gaseous state, is compressed by the refrigerator's compressor. This action increases the pressure and temperature of the refrigerant, preparing it for the next stage of the cycle.

Step 2: Expelling the Hot Air

Once the refrigerant is compressed, the hot air needs to be expelled. The high-temperature refrigerant moves through the condenser coils located at the back of the refrigerator. Here, the hot air is pushed out, allowing the refrigerant to cool down and transition into a high-pressure liquid.

Step 3: The Transition of Refrigerant to Liquid

As the refrigerant cools, it transitions from a gas to a liquid. This change of state occurs in the condenser, where the refrigerant releases its heat to the surroundings, causing it to condense and become a liquid.

Step 4: The Journey of Refrigerant into the Evaporator Coils

The high-pressure liquid refrigerant then flows into the evaporator coils located inside the refrigerator. This is where the refrigerant prepares to absorb the heat and cool down the interior of the refrigerator.

Step 5: The Absorption of Heat

Inside the evaporator coils, heat from the interior of the refrigerator is absorbed by the refrigerant. This process cools down the interior, preserving the freshness of the products stored inside.

Step 6: The Evaporation of the Refrigerant

Post heat absorption, the refrigerant, now a low-pressure liquid, evaporates back into a gas. This evaporation process further absorbs heat, aiding in keeping the refrigerator's interior cool and fresh.

Step 7: The Recurrence of the Cycle

Once the refrigerant has evaporated and absorbed all the necessary heat, it returns to the compressor. Here, the cycle begins anew, ensuring that the commercial refrigerator maintains a consistent cooling effect.

In conclusion, the working of a commercial refrigerator is a continuous cycle of compression, heat expulsion, refrigerant liquefaction, flow into the evaporator coils, heat absorption, refrigerant evaporation, and cycle repetition. This intricate process ensures an efficient and effective cooling system, preserving the freshness and quality of the stored products.
