The commercial refrigeration process can be quite complicated. Indeed, the technologies involved have dramatically advanced during the past few decades. While a portion of this momentum is centred around higher levels of efficiency, the need to reduce hydrocarbons within the environment has been another key motivating factor. Although this is a rather in-depth topic, it is still wise to take a brief look at how the refrigeration process works and what mechanisms are involved.
The Role of the Commercial Refrigeration Compressor
Perhaps the most important component of any commercial refrigerator is the compressor. This is a device which pumps refrigerant vapour through a series of coils at a high pressure. As this vapour travels through these coils, it meets the outside air of the kitchen and loses much of its heat. Then, the vapour will cool down the interior of the refrigerator. In essence, the compressor is the main device which enables the vapour to travel through the coils and keep the entire unit cold.
While the commercial refrigeration compressor may require much more coolant to be used, the underlying principles of vapour convection through the coils remains the same. However, it should also be noted that there are several types of commercial compressors which can be used. One is known as a variable speed compressor. As the name hints, it is able to automatically adjust its speed as is required to achieve optimal temperatures. This is ideal when one is looking to reduce energy consumption and electric bills. Also, it is said that this variant can last longer than a traditional model. Another useful mechanism is a variable-frequency drive. Once again, this drive will increase or decrease the speeds at which the compressor motor is running. As a refrigerator (even a commercial variety) is rarely operating at its peak capacity, variable speed drives (or VFDs) can help to increase the efficiency of the unit and lengthen the lifespan of the motor in question.
It is clear to see that this technology has vastly increased during the past few decades. As such systems continue to evolve, the consumer can expect to enjoy even more cost-efficient and reliable refrigerators.
