Refrigerants are the most important of all gases used in industrial refrigeration systems. They are particularly required in order to keep the products inside the refrigerators at a constant temperature. Refrigerants are widely used in refrigeration because they have excellent chemical properties and an excellent life span. They also have very low vapour pressure and freezing temperatures and they also occur in organic compounds with high stability. They can also be recycled easily.
The commonly used refrigerants are ammonia, carbons, carbon dioxide, chlorine, creatine, dextrose, glycerol, hydrochloric acid, hydrogen, hydroxymethane, nitrogen, carbon dioxide, and sulphur. The names of the refrigerants are derived from their properties and functions. They are usually divided into two broad categories. The first of these are ‘Free Cooling’ and the second one is ‘Self Cooling’. These two categories are usually differentiated by the use of certain substances for ensuring the process of refrigeration.
Ammonia is the most commonly used refrigerant. It is an extremely volatile gas which is dangerous when it comes in contact with eyes, skin, or mucous membranes. It is also liable to be explosive if exposed to fire. However, it is the best suited refrigerant for industrial use as it does not create any hazardous by products. It is usually used as a stabilizer, in cleaning equipments, and for deodorizing purposes.
Carbons are used to increase the freezing point of products. They are particularly useful for animal feed which has to be kept frozen at all times. They are also commonly used for coating foods and for controlling the growth of bacteria and fungus on meat. Ethylene is another common refrigerant. This is a refrigerant that is widely used for flushing pesticides and other industrial cleaners.
Crystal refrigerants are often used as blueprints in industrial plants. They are highly suited for industries as they do not produce any harmful by products. They are however, very expensive and their availability is limited. Fluorine is also a good example of such a refrigerant.
The three mentioned refrigerants have different features and it is due to this reason that each one is used for a specific purpose. It is important that you get the right type for your industry. Some of the refrigerants mentioned above have special qualities like low boiling points. Hence, they should only be used in specific applications where they perform well. If you are not sure whether you need to use a refrigerant, you can get in touch with an expert or a representative of a company that makes refrigerants. Chances are that the company will be able to give you a clear insight into what you need to do.
If you buy high quality refrigerants for your industrial plants, you can greatly enhance the productivity of the workers operating the machinery. Since high temperatures play a major role in the manufacture of most of these refrigerants, you should only choose those that are specially designed for high temperature operation. Once you find suitable refrigerants for your co2 cascade refrigeration system, you can save a lot on energy cost.
Industrial refrigerants are usually available at highly affordable prices. However, before buying any of these products, it is advisable that you check out the co2 emissions produced by the products. If the product has a low boiling point, it is likely to emit more co2 than other refrigerants. A lot of research has been carried out to check out whether the products produce excessive levels of co2. It has been found that while some of the refrigerants do not produce such high levels of emissions, others can actually cause harm to the environment.
