Why hydrocarbon refrigerant – HC

1. Introduction.

A well-known scientist at this time who also introduced the theory of relativity, namely Albert Einstein, said in his research study on hydrocarbon materials as a cooling fluid media material or refrigerant material used in refrigeration cycles with vapor compression, said that the king of refrigerants is hydrocarbons. At that time not many scientists understood this statement, so only a few scientists understood it. Even though the patent rights for hydrocarbon refrigerants are currently held by him based on information from several news reports. Since it was discovered as a natural refrigerant as a natural refrigerant, of course, its main characteristic of being flammable has become a characteristic that cannot be eliminated. However, with the development of science regarding the flammability of a single gaseous material, hydrocarbon refrigerants have a lower flammability limit and an upper flammability limit. In accordance with scientific developments related to refrigerant materials, where currently refrigerants can be burned is an obstacle to be considered for choice, synthetic refrigerants are made which are known by their groups called CFCs, HCFCs, HFCs. The manufacture of synthetic refrigerants is made from hydrocarbon refrigerants by eliminating some of the hydrogen elements by replacing them with Cl (chloro) and F (floro) elements. The addition of the two elements to eliminate the hydrogen element in hydrocarbon materials also makes synthetic refrigerants non-flammable and flammable. And the use of Cl and F materials as well as in hydrocarbon materials not only produces synthetic refrigerants, but produces blowing agents, produces propellant, produces aerosol gases, and many other materials are produced. Some reviews of hydrocarbon refrigerants will be presented in this paper.

2. Environmental aspects and hydrocarbon refrigerants.

Climate change that is currently sweeping the world and its people too, one of which is caused by synthetic refrigerants used in cooling machines from air conditioning units and refrigeration unit units since they were discovered until now many of which are still present in the earth's atmosphere. As a result, the earth's temperature continues to rise and becomes a serious and ongoing threat to mankind in the world. Many research results have been conducted on these synthetic refrigerants which pollute the environment, and the results of the latest report show that this type of environmental pollution occurs in the presence of the next generation of synthetic refrigerant materials, which can lead to TFA and PFAS diffusing materials. And until now there are synthetic refrigerants that have been released into the atmosphere that cannot be recycled by nature. Hydrocarbon refrigerants whose basic ingredients are made from natural ingredients have a very small impact on environmental pollution, do not cause damage to the ozone layer, very little cause global warming effects, and nature's ability to recycle is very short in time compared to synthetic refrigerants. In addition, hydrocarbon refrigerants are one of the material choices in determining the decarbonization program of the refrigeration sector.

3. Ability to convert synthetic refrigerant.

Hydrocarbon refrigerants have the ability to replace synthetic refrigerants used in refrigeration machines, from several studies and applications this has been proven and has even been widely used in many refrigeration installations by showing good performance. Since being reintroduced as natural refrigerants, several types of hydrocarbon refrigerants have now been widely used in refrigeration units in the refrigeration sector and in the air conditioning sector. Hydrocarbon refrigerant materials that are currently being introduced to the wider community include R-600, R-600A, R-290, R-1150, R-1270, and others, with variations in thermodynamic prices and the characteristics of the material, have been able to replace synthetic refrigerants. currently available by converting the refrigerant.

4. Hydrocarbon refrigerants and their thermodynamic characteristics.

As it has been stated that the king of refrigerants is hydrocarbon refrigerants, when viewed from a thermodynamic aspect, they have good advantages. Among them is the use of the total weight of the hydrocarbon refrigerant which is only 1/3 the weight of the synthetic refrigerant it replaces, so this is an indicator that can reduce the consumption of electric power required by electric motors in compressors, the ability to mix with compressor lubricating oil is quite good for this type of synthetic lubricating oil as well as mineral type compressor lubricating oil, has good ability against materials made of synthetic rubber, and also has the ability with metal materials used in refrigeration machines in general, hydrocarbon refrigerants have quite a lot of types with different pressure characteristics that can be adjusted according to pressure the synthetic refrigerant monkey it replaces, has a considerable latent heat content.

?5. Cover.

Some of the things that were disclosed are of course only partially owned by hydrocarbon refrigerants, so that in accordance with future developments, hydrocarbon refrigerants are one of the refrigerant materials that can help in overcoming the effects of climate change for a long time. However, synthetic refrigerants that have been introduced reduce their ability to damage the ozone layer, reduce the effects of global warming, however, it is predicted that they will face challenges to the environment, such as the newly introduced HFO refrigerant, which has been stated by several environmental experts to produce environmental pollution by the formation of TFA and PFAS. . On the one hand, synthetic refrigerants can solve environmental problems, but on the other hand, new environmental pollution problems arise. Hydrocarbon refrigerants are an option for use in refrigeration machines for long-term use to reduce the impact of climate change.
