The cooling coils are undoubtedly an essential part of a refrigerator. The refrigerant vapor is pressurized by the compressor and reaches the cooling coil outside of the refrigerator chamber, where it promptly condenses back into a liquid. 

A simple answer to your question is: Copper is a great conductor of electricity, which is why commercial refrigerator cooling coils are made of copper. To know about it in detail and if there are any alternatives to copper cooling coils, stay hooked here!

The Function of Cooling Coils in a Commercial Refrigerator

The refrigerant is held in liquid form by the cooling coil, which is made of copper. The compressor raises the gas’ pressure. As a result, the gas condenses into a liquid. The heat contained in the refrigerant is released as the refrigerant transitions to a liquid form. Outside, the heat is diffused. The liquid refrigerant then returns to the interior, resuming the cycle.

What Role Does Copper Play?

The coolant flows through an evaporator made up of numerous thin wires, generally made of copper. The heat is absorbed by these wires, which run between the coolant pipes and are then dissipated.

Because copper is generally innocuous and has high ductility, it is ideal for evaporator tubes (it can be stretched, molded, and drawn into thin wires quickly). This means it can be soldered quickly at low temperatures and create tight seals. This is true in India for any deep freezer. The complete copper arrangement is used with low-melting-point compounds that have strong adhesion properties.

Copper has the unmistakable benefit of being a great thermal conductor. Compared to other conductors like aluminum, it also shows less internal material fatigue from cyclical temperature and pressure fluctuations.

Despite the fact that copper is more expensive than aluminum, it is considerably easier to fix. As a result, copper coils are stronger and more long-lasting.

On the subject of maintenance, it has been discovered that copper coils are preferable to steel coils in deep freezers in India, which must adjust to various climate conditions. Copper coils are also easier to clean and maintain. Unlike aluminum coils, which must be protected from harm by being housed inside a cabinet, copper coils may be maintained with minimal coverage.

Alternatives to Copper Cooling Coils

Aluminum, carbon steel, stainless steel, nickel alloys, and titanium are some of the alternative materials. However, copper has the maximum thermal conductivity, while aluminum has about half of copper’s thermal conductivity. Also, you now see why steel is rarely or never used for coils.

As a result, copper performs considerably better in terms of cooling than other cooling coil alternatives. This is the primary reason why copper is favored for commercial refrigerators over other metals when performance is crucial.

Copper coils can corrode if they are exposed to air and water for an extended period. However, because copper is a strong metal, this is not a typical occurrence. These coils are less difficult to repair and can be used when they have been properly repaired. Corrosion can also be avoided with regular maintenance and cleaning. Furthermore, many modern coils come with paint coats that are specifically intended to resist corrosion. Therefore, copper coils are very cost-effective in the long run.
