Air conditioners are a must have in modern times, both for comfort and also as a sign of status in the society. So why don’t you get some basic knowledge about the most important thing regarding the air conditioners?
Refrigerants – what you should know?
Yes, you are right. It is the refrigerant which is a mixture, especially a fluid. This is used in the heat pumps and in the refrigeration cycle. It has to pass some of the phase transitions which transform the liquid to a gas and the reverse too. Numerous working fluids are used for this purpose. The compounds of fluorocarbons or chlorofluorocarbons were commonly used in the twentieth century. But now they are not in use due to the depletion effects of ozone. The compounds of ammonia, sulfur dioxide and some of the hydrocarbons like propane are used now in the refrigerants. In fact, in the various continents the refrigerant handling license is provided after certain degrees.
The refrigerant ideally has all the thermodynamic properties. These properties should have a boiling point, a high heat of vaporization, a moderate density in the form of liquid and a high critical temperature. The boiling point and the density of the gas are generally affected by the pressure. They will be non-corrosive to the components which are mechanical and they should be free from the toxicity as well as flammability. The refrigerants should never cause the depletion of ozone and bring change in the climate. To get a refrigerant handling licence, you need to have the basic knowledge of refrigerants.
These refrigerants are non-flammable and non-toxic. Their stability as well as their potential for global warming and ozone depletion has increased the concern of their random usage. The Bromo chlorofluorocarbon, CFC and HCFC are the potentials of ozone depletion. But PFC is not potential, it is non-ozone potential. The new refrigerants, which are getting prepared in the twenty -first century do not cause any harm to the environment. They are safer for the healthy atmosphere and pollution will be lessened. Their applications have been held up for the concerns regarding the factors of toxicity as well as flammability.
Refrigerants are used widely in technologies
These refrigerants are used in the systems of air conditioning in buildings, sports, various industries, automotive as well as food industries (which include the food production, storage, and retailing too). After the removal of the refrigerants they are recycled for cleaning up of the contaminants and they are transformed into the previous condition. Some of the refrigerants can be even dangerous after the recycling process is done.
To pursue a course or training course on refrigerants, you should choose the right place.
