The cooling system in a refrigerator is probably the most significant inventions man has built. This technology, which is now a standard fixture in modern society, has produced an excellent effect not only in the realm of food storage, but even in medicine, science, technology, and even in recreation and culture. Fridges are utilized nowadays in both small-scale applications in the house, to large-scale storage devices in commercial establishments. However, it is essential to be aware of the differences between refrigerators for domestic use and industrial refrigeration. Experts state that the choice in refrigerant for each depends on a multitude of aspects, including the size of the machine to be employed, safety precautions, and even the area to be cooled.
There are many qualities that refrigerator users should look into in choosing coolants for industrial refrigeration or even basic home use. The first among these qualities is the boiling point of the refrigerant. Usually, chemicals with a boiling point that is below the target temperature are ideal for cooling, whereas those having a higher boiling point are definitely more effective in smaller systems. The boiling point is very important as this determines how quickly the refrigerant can turn into a vapour and therefore, take up heat and create a lower temperature. Together with a low boiling point, an excellent refrigerant should also have a high latent heat of vaporisation. This quality signifies how much heat the refrigerant must absorb before turning into vapour.
An additional refrigerant quality to be considered is safety, and this involves 2 properties: toxicity and flammability. With regard to toxicity, refrigerants are categorized into Class A (no toxicity in concentrations lower than 400 parts per million) and Class B (with toxicity detected). Flammability of refrigerants, on the contrary, is divided into 3 classes: Class 1 (totally non-flammable), Class 2 (somewhat flammable) and Class 3 (extremely flammable). Ideally, a refrigerant must be non-toxic and non-flammable. Fridges for domestic use usually contain Class A and Class 1 coolants, while industrial refrigeration can make use of higher class refrigerants since commercial entities commonly utilize rigid safety precautions.
Colour and odour should also be taken into consideration when setting up refrigerators. Refrigerants are typically colourless and odourless, but users could add colour or make use of a refrigerant with a unique odor (such as ammonia) for easy detection of leaks. Finally, firms that will make use of industrial refrigeration must look into the stability of the refrigerant to be employed. An excellent coolant must be stable; which means that it should not react with any component of the cooling system, nor should it decompose under the various pressures and temperatures of the system. This sort of quality implies that the cooling system can be utilized for extended periods without regular repair or replacement of parts and machines.
The difference between refrigerators for home use and industrial refrigeration, Australia industry experts say that it should be taken into account and will rely on numerous factors like the size of the equipment to be used, safety measures and the area to be refrigerated.
