What is the coolant?
refrigerant is a chemical used in cooling systems for mechanical devices such as refrigerators, freezers or air conditioning. Most cooling units depend on the chemical reactions of the refrigerant gas to remove heat from the closed area. In fact, there are many gases that have been used as refrigerant. Early refrigeres were highly toxic and dangerous chemicals. The modern gases that have replaced them are safer, but many can have a harmful effect on the global environment.
Artificial cooling using mechanical and chemical processes was developed in the 19th century. Chemists have long known that some chemical reactions absorb or dissipate heat, which reduces the temperature in the area. The food and beverages of that time needed an alternative to costly and inefficient cooling methods involving the transport and storage of ice. Inventors such as American Thaddeus Lowe have created complex systems using chemicals to draw heat from closed areas, Creating chilledcompartment. Most of these systems included a form of refrigerant gas.
The mechanical cooling system depends on the storage of a certain amount of refrigerant or gas. The device creates controlled chemical reactions by forcing gas to change the condition or its combination with other chemicals and draw heat from the chilled section. Early commercial and homemade cooling units used gases such as ammonia and methyl chloride. These gases are highly toxic and could cause injury if they have escaped or required maintenance. For this reason, most early gases of refrigerant are no longer used.
In the 1950s, domestic cooling units were common in most households in developed countries. Manufacturers of these devices have replaced toxic refrigerant gases with synthetic refrigerations called chlorofluorocarbones. They were safer to manipulate and store, but soon scientists found that they had their own problems. In the 1970s of the 20th century, studies revealed that chlorofluorocarbons used in cooling units and other devices contributed to the exhaustion of ozone. Ozone depletion, which can increase the harmful effects of sunlight, was one of the first environmental crises to be widely understood, and international conventions soon banned chlorofluorocarbons.
continuing cooling progress has created a safe alternative refrigerant and efficient machines that require a fraction of coolant chemicals used by older units. However, older refrigeres are still required for older devices that are still used, for example in cars or industrial freezers. It cannot be converted to modern refrigeres without disabling costs. Government bodies, such as the United States Agency, have strict regulations on the use and liquidation of refrigerant. Individuals requiring the maintenance of the cooling should always be consulted by a qualified technician.
