Hermetic compressor: how to choose the right one

In the commercial compressor segment you will find many different technologies. Today, most of these compressors are screw or scroll type. But there is one dimension to take into account if you are considering which kind of compressor to utilize.

The compressor dimension can be seen as a kind of architecture that underpins the technology. Depending on this, we distinguish:

• Hermetic compressor

• Semi-hermetic compressor

• Open compressor

There are various types of reciprocating or screw compressors available on the market that correspond to these three structures. Of course, certain technologies and applications are associated with certain approaches. Which compressor architecture you choose will have a significant impact on the performance of your system. When it comes to compressor selection and deployment, making the right choice the first time is important. Especially when it comes to refrigeration or air conditioning systems, it is important to choose a compressor based on careful study of the available information.

What is a hermetic compressor?

A hermetic compressor is a type of compressor that is only sporadically used in large industrial or commercial applications. In general, however, it is probably the most widely used compressor in the world, as it is part of many smaller appliances, within consumer goods such as domestic refrigerators. It is a compressor that is completely enclosed from the environment and is therefore housed under a structural envelope. Its internal components cannot be accessed without damaging it.

The very term hermetic is defined as airtight. In this context, a hermetic compressor is completely separated from the external environment. With this compressor, malfunctions due to clogging of dirt or spillage of oils or refrigerants are eliminated.

When the hermetic compressor hits its limits

H. compressor also has its disadvantages. These limit the way it can be used, especially in harsh environments. Therefore, they are usually limited to smaller systems.

One of the most common places where a hermetic compressor is used is in small refrigerated display cases in shops. In these cases, a small, lightweight hermetic compressor is absolutely ideal. However, when you need to maximize performance and efficiency, the effect of a hermetic compressor is greatly missed. In the event of a mechanical problem, such a compressor cannot be opened. The problem may be simple and easy to fix, but your only option is to replace the compressor altogether.

When is a hermetic compressor a sure bet?

Hermetic rotary compressors are compact, efficient and reliable devices used in air conditioning systems, refrigerators and freezers. The movement of the rotor in the enclosed space creates compression chambers that allow the refrigerant to be compressed. Compared to other compressors, hermetic rotary compressors offer advantages such as quiet operation, energy efficiency and precise modulation capabilities for optimum temperature control. Their compact size, low noise level and energy savings make them the preferred choice in a variety of applications, ensuring efficient performance, convenience and cost savings.

The H. compressor is so often preferred just in cases such as small applications. Their use is also widespread in these situations because of the low initial cost and elimination of maintenance requirements.

Optimizing maintenance and energy efficiency of hermetic compressor

The hermetic compressor has a sealed design. On the one hand, this reduces possible wear and tear on the individual components, but it also makes servicing and maintenance more difficult. It is thus only possible to take care of the compressor from the outside.

This type of compressor usually runs more efficiently due to its sealed environment, thus eliminating energy losses. However, as already mentioned, the initial cost of a hermetic compressor is lower, but the compressor is designed for one use only.

Conclusion

The hermetic compressor is a key technology that ensures efficient and reliable operation of refrigeration, air conditioning or other industrial applications. Their enhanced features, such as lower energy consumption and longer service life, make them an ideal choice even in more demanding but smaller systems.
