RefrigerantRefrigerant it’s a adjective which refers to what refrigerate. Refrigerate, for its part, is the action carried out to get the temperature of something to drop.

The term can be linked to conduit which has a double wall: a liquid flows through it which is cooled by the influence of another that is in the external enclosure.

A refrigerant, on the other hand, is a substance that absorbs the heat of another body and that, therefore, cools it. The Water, either in liquid or as ice, it is the most common refrigerant and has been used since prehistoric times.

Over time, the man began to investigate the action of these refrigerants, adding salt to water, modifying the steam pressure and using compressed air. Already in the XIX century, the use of methyl chloride, ammonia and other fluids such as refrigerants.

At present, the refrigerants used at an industrial level must have certain properties that guarantee their stability and safety during use. In general, these are substances that are not flammable or explosive, and also do not corrode the materials with which they come into contact.

Teams air-conditioning, cold rooms and ice factories are some of the facilities that require refrigerants for their operation. In automobiles, a refrigerant is used that combines glycol and water to dissipate heat from the motor and thus prevent overheating.

Coolant and water in cars

RefrigerantChoosing a good coolant for your 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 common 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 acting as an antioxidant and having a Boiling point superior to water, 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 to limit yourself to using the liquid recommended by the vehicle manufacturer.

But what happens if we use water instead of coolant, exactly? In the first place, it can lead to the formation of particles that act as a blockage in the system, making flow difficult and exposing it to excessive temperatures and high pressures.

Furthermore, if water has been used for a long time, going directly into 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 ducts it passes through, dragging all the elements that it finds in its path, and when it promotes the detachment 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. However, it should be mentioned that the instructions produced by car manufacturers always specify what kind of fluid should be used.

As a curious fact, the higher the height above sea level in a city, the lower the boiling point of liquids, both water and coolant. Although these are minor differences, of a few degrees, this may be one more reason to avoid the use of water in the cooling system.
