Refrigeration compressor: what to watch out for

If your business involves products that depend on being kept chilled or frozen for their lifetime, you will certainly see the importance of a properly functioning refrigeration compressor. It is the heart of the refrigeration unit, and when it is pumping properly, your unit is working at its best.

Knowing your commercial or industrial compressor is very important. But not everyone is able to judge the technical characteristics of refrigeration compressors. In case of breakdowns, the greatest certainty is to contact certified companies that deal with refrigeration compressors. Using the services of such companies can significantly shorten the removal of the fault compared to self-help repairs.

What is a refrigeration compressor

As already mentioned, the compressor is the heart of the cooling system.

Technically, the compressor works as a pump that increases the pressure of the incoming refrigerant gas. As a result, the volume of the gas decreases while its temperature rises. The refrigerant gas is then cooled in the condenser and changes its state to liquid. Through the expansion valve, the coolant enters a lower-pressure environment, evaporates and evaporates in the evaporator, and reabsorbs heat from the surroundings. The refrigerant gas then flows back into the compressor to start all over again.

The refrigeration compressor is therefore an integral part of any refrigeration system. When it comes to commercial refrigeration compressors, it is very important to pay attention to quality. Buying the wrong compressor can cause huge losses.

Refrigeration compressor type

Each type of compressor is suitable for a specific application. So get the compressor that will suit your cooling needs.

Reciprocating compressors are also commonly referred to as reciprocating pumps. They use a piston and connecting rod design to move refrigerant through the system. Some are also referred to as hermetic compressors, which means that the casing is airtight. These compressors are reliable and widely used in commercial refrigeration.

Screw compressors work on the screw principle. The refrigerant is compressed in the space between the two screws. These compressors are mainly used in large applications because they can handle large quantities of refrigerant and are stable even under long-term loads.

Scroll compressors use innovative technology. This compresses the refrigerant through two spirals. They consist of fewer moving parts, which limits breakdowns. These compressors are more robust and are a suitable alternative to reciprocating compressors, which are not as durable.

A modern inverter compressor uses a variable frequency drive to control the compressor motor. This adjusts the cooling capacity to match the current requirements. These compressors are most commonly used in air conditioning and commercial refrigeration applications where stable and efficient operation is required.

Of course, you can choose from different types of compressors on the market today. Reciprocating ones are usually cheaper but also noisier than rotary ones. Rotary, i.e. scroll and screw compressors are often a better choice for larger cold rooms and boxes, among other things, they usually have a longer service life and are generally more durable and reliable.

Refrigeration compressor and energy saving

Significant progress has already been made in the field of refrigeration compressors, so it should not be a problem to find energy-efficient alternatives on the market. However, it should be taken into account that each type of compressor has a different energy efficiency rating. So you have to balance between efficiency, noise and also the difficulty of installation. When buying, consider the energy efficiency of each type of compressor technology. By evaluating the efficiency of each type, you can choose the most economical option and reduce your energy bills.

Refrigeration compressors combined with photovoltaics are the green option and the most energy efficient solution. They reduce electricity consumption and environmental impact.

Refrigeration compressor and performance

When buying a refrigeration compressor, consider the performance of your cooling system. Compressors do not operate in the same range. A compressor may be good, but if it doesn’t match the capacity requirements of your unit, the entire system won’t work properly.

Properly matching the compressor to the original unit will maintain the functionality needed to do its job efficiently for years to come.

Refrigeration compressor and noise level

Noise is an unavoidable by-product of a refrigeration compressor. But recent technological innovations have reduced the amount of noise produced. Complete silence within refrigeration technology has not yet been achieved, but some compressor models produce minimal noise.

When selecting a refrigeration technology, the size of the compressor plays an important role in its efficiency and noise level. The size of the compressor also determines how much refrigerant is circulated in the system. A larger compressor can circulate refrigerant faster, which increases efficiency, while operating at a lower speed, reducing the noise it creates.

When selecting a refrigeration compressor, it is necessary to match the cooling capacity requirements of the system. An undersized compressor will not be able to keep up with the cooling requirement. An oversized compressor without inverter technology, on the other hand, will perform adequately, but will also shut down more frequently, which can reduce its service life. Not to mention that frequent on and off can be more disruptive than continuous operation.

Conclusion

Choosing the right compressor is important to ensure the performance and longevity of your refrigeration equipment. It is important to consider many factors when making your selection. Remember to compare prices and energy efficiency ratings. When evaluating price, also consider the cost of installation and future repairs and maintenance. By evaluating these factors, you can make an informed decision and select the best type of compressor for your needs.
