5. Inactive To Lubricating Oils The refrigerator should not react with lubricating oils and easily break them apart. This type of refrigerant material is considered to be of the best class. This property is found in ammonia. 6. Low Toxicity The refrigerant should not be poisonous. If it is poisonous, leakage of refrigerant material from the system should be easily detectable so that any damage can be avoided by quickly closing the leak. 7. Corrosiveness Of Metal Refrigerant metals should not be smelted. That is, do not react to erosion with metals. If the refrigerant performs erosion on the ducts used, it will burn or strangulate or pierce them. Consequently, they will have to be replaced quickly. Therefore, the cost of running the plant will increase. 8. Refrigerants Should Be Non-Inflammable And Non-Explosive The refrigerant to be used should not be fire-catching and explosive so that it will be safe to use. There is a greater possibility of damage if the refrigerant is flammable and explosive. 9. Low Viscosity The less gluten in the refrigerant makes it easier to flow through the ducts, meaning that the viscosity is less likely that the refrigerant can easily move into the tubes. 10. Low In Cost The refrigerant should be easily available and low cost. Causes Of Depletion Of The Ozone Layer The depletion of the ozone layer is a major concern and is associated with many factors. The main reasons responsible for the depletion of the ozone layer are listed below: Chlorofluorocarbons Chlorofluorocarbons or CFCs are the main cause of the depletion of the ozone layer. These are issued by soaps, solvents, spray aerosols, refrigerators, air-conditioners, etc. Molecules of chlorofluorocarbons in the stratosphere are broken by ultraviolet radiation and release chlorine atoms. These atoms react with ozone and destroy it. Irregular Rocket Launch Research says that the erratic launch of rockets causes a much greater depletion of the ozone layer than CFC. If this is not controlled, by the year 2050, the ozone layer may suffer a huge loss. Nitrogenous Compounds Nitrogenous compounds such as NO2, NO, and N2O are highly responsible for the degradation of the ozone layer. Natural Reason The ozone layer is inferior to some natural processes such as solar spots and stratospheric winds. But this causes the ozone layer to decrease by more than 1-2%. Ozone Depletion Substance Ozone-depleting substances are substances such as chlorofluorocarbons, halons, carbon tetrachloride, hydrofluorocarbons, etc., which are responsible for the decay of the ozone layer. Final Words: Different Types Of Refrigerants If you’re someone who cares about energy efficiency and the environment, choose an air conditioner with R-290 or a Refrigerator with R-600A. The more you decide on it, the more the manufacturers will start using them in their appliances.  Remark： Some of the articles are taken from the Internet.
