In each house there is such an essential unit as a refrigerator . His life without him is so difficult to imagine: thanks to the refrigerator, we can store food and ready meals without problems. And if a breakdown happens, all members of the family are inconvenienced. By the way, a frequent breakdown is the leakage of freon from the refrigerator. This is exactly what will be discussed.
What is freon in the refrigerator?
In general, refrigerators that operate on a compressor are cameras with an evaporator inside. In the evaporator there is a refrigerant - a substance that, during boiling and evaporation, removes heat from the chamber and transfers it to the medium during condensation. Thus, the air in the refrigerator is cooled, and the refrigerant in the gaseous state enters the compressor and condenses again into the liquid state. This cycle is repeated and repeated.
But freon is a chemical compound based on ethane or methane. If we talk about where the freon is in the refrigerator, then this substance is located in the evaporator. This means that freon is a type of refrigerant that circulates and thanks to which the cooling chamber is cooled.
Currently, different brands of freon are used. For home refrigerators, freons such as R-600 and R-134 are usually used. Industrial and commercial refrigeration chambers are filled with R-503, R-13 and others.
Freon leak from the refrigerator: signs
As you can see, freon is one of the main components of the serviceable operation of the unit. Its leakage leads to the fact that it is impossible to use the device necessary for each household by appointment. Usually such a breakdown occurs when the evaporator tube breaks down or as a result of factory rejection.
But how to understand that the freon from the refrigerator came out? First, despite the fact that the type of refrigerant in question is a volatile gas, it is impossible to understand the breakdown by the way freon from the fridge smells - it does not have a smell. Secondly, the problem is unlikely to be recognized by the color of freon in the refrigerator - again this substance is colorless.
However, there are certain signs that this breakdown in the unit is easy to suspect. The fact is that when the evaporator tubes are damaged, the pressure of freon in the refrigerator naturally decreases gradually, and so the condensation process slows down. Therefore, in the refrigerator and freezer the temperature of the air increases, because of which perishable products, for example milk, can deteriorate. You can notice the running water under the refrigerator as a consequence of the fact that the products in the freezer melt. By the way, you can not worry about freon poisoning from the refrigerator. This chemical, although it has 4 levels of toxicity, but Freon in the refrigerator is dangerous only when heated to 250 ⁰C, which at home does not happen.
How to repair a freon leak?
Unfortunately, it is impossible to eliminate the leak of freon by yourself - the specialist will need help. Before making
Then the refrigeration equipment repairman seals this section or replaces the entire evaporator. After suctioning the contents of the system with a vacuum pump, the refrigerant is refilled with refrigerant.
The refrigerator is considered to be serviceable if the corresponding temperature is set after switching on in the refrigerator and freezer compartments.
