Refrigerant is a adjective which refers to what refrigerates . Refrigerate , meanwhile, is the action that is performed to get the temperature of something to drop .
The term can be linked to conduit which has a double wall: through it flows a liquid that is cooled by the influence of another that is in the outer enclosure.
A refrigerant, on the other hand, is a substance that absorbs the heat of another body and that, therefore, cools it. He Water , either in a liquid state or as ice, it is the most common refrigerant and it has been used since prehistoric times.
Over time, the man He began to investigate the action of these refrigerants, adding salt to the water, modifying the vapor pressure and using compressed air. Already in the XIX century , the use of methyl chloride , ammonia and other fluids as refrigerants.
At present, the refrigerants used at industrial level must have certain properties that guarantee their stability and security during use In general they are substances that are not flammable or explosive, and that also do not corrode the materials with which they come in contact.
The teams of air conditioner , cold rooms and ice factories are some of the facilities that require refrigerants for operation. In cars, a coolant is used that combines glycol and water to dissipate heat from the engine and thus prevent overheating.
Coolant and water in cars
The choice of a good coolant for the car is not easy, since there are many options and also different points of view about what is the best practice . Some people even wonder if it is possible to mix it with Water current. Another usual question is how often it is necessary to replace it. Let's see below some concepts and points of view related to this topic.
Thanks to act as an antioxidant and to possess a Boiling point higher than water, the coolant is more efficient for a car's cooling system. Based on this explanation, it is correct to say that it is not advisable to mix both products or simply opt for water, but only to use the liquid recommended by the vehicle manufacturer.
But what happens if we use water instead of coolant, exactly? First, it can lead to the formation of particles that act as an obstruction in the system , hindering the flow and exposing it to excessive temperatures and high pressures.
In addition, if water has been used for a long time, passing directly to the coolant can also have negative consequences, such as causing damage to the cooling system. A very precise reason is that the coolant is also capable of cleaning the pipelines it crosses, dragging all the elements it finds in its path , and when it promotes the shedding of fragments of the oxide caused by water, these can clog or damage soft parts of the engine, such as hoses.
To avoid such a situation, it is best to take the car to a specialist, to examine it and determine if the change can be made. In any case, it should be mentioned that the instructions developed by the car manufacturers always specify what kind of liquid should be used.
As a curious fact, the higher the height above the sea level of a city, the lower the boiling point of liquids, both water and coolant. Although these are minimal differences, of a few degrees, this may be another reason to avoid the use of water in the cooling system.
