Industrial refrigeration differs greatly from domestic refrigeration because of the large scale and complexities involved. Ammonia cooling systems make the basis of industrial refrigeration for industries such as frozen foods, pharmaceuticals, food processing and beverage processing. If you are engaged in manufacturing or supply chain for such perishable products, you need to know all about ammonia refrigeration system. Complicated as it may be, this system is not rocket science. Considering the fact that your business entirely depends on this system, you should happily invest some efforts in understanding the basics.
How exactly does refrigeration work?
Refrigeration works on the principle of moving the heat energy from one area into another so that it becomes cooler. Vapor compression is the key technology used in refrigeration systems. The refrigerant (coolant) used in such units is a vapor that compresses to become a liquid and then expands again to become a vapor. A compressor does the job of pumping up the refrigerant through the evaporation coils and then through the condensation coils. As the refrigerant vaporizes, it takes up the surrounding heat and releases it elsewhere on condensation. The process is repeated as a cycle which results in cooling. The temperature range and cooling ability of the system greatly depends on the refrigerant it uses.
As such, this determines the overall efficiency of the system. Now that we have understood the basic principle of refrigeration, lets see the reason that ammonia is preferred as an industrial refrigerant.
Why ammonia as a refrigerant?
Ammonia emerges as the ideal choice for a refrigerant used in large cooling systems such as those used in industrial facilities. The reason is that it is far more efficient in comparison to the competitive refrigerants. It enables high cooling with less power, making it effective for lowering long-term operational expenses in industrial settings. Moreover, the environmental footprint of this gas is relatively low as it breaks down quickly in the environment. Unlike the synthetic refrigerants, the gas does not affect the ozone layer. Another reason that ammonia is considered as the best choice for industrial refrigeration is that its strong odor makes it easy to identify any spill or accidental release. This means that any issue related to the coolant leakage can be easily identified and resolved. Also, the fumes of ammonia can be toxic, which is the reason that a leak is to be checked and corrected in time.
Which industries rely on ammonia refrigeration?
The choice of an industrial refrigerant greatly depends on the product to be stored or processed and its temperature requirements. Ammonia is ideally suited for facilities that require large tones of refrigeration, such as dairies, meat-processing plants, petrochemical plants and the brewery industry. In general, the lower the temperature requirement, the more cost-effective ammonia becomes as a coolant.
However, installation and maintenance of ammonia refrigeration systems require a great degree of skill and experience. Experts at AltaRefrigeration.com can be trusted for the job.
