Freon – is the temperature of the refrigerant. Freon in the refrigerator

Each house has appliances for the production and efficiency of such a substance which is used as the refrigerant. This substance is known as an excellent refrigerant used in all fridges so you can store food and ready meals for a longer period than the ambient temperature. This article will tell freon – what is the matter, where it is used, what temperature it is.
History of discovery
Various sources call the first two dates synthesis Freon – 1928 and 1931 years. Correct that the date of birth of the refrigerant 1928 year. It was then a prominent chemist Frigidaire Company, a subsidiary corporation General Motors, Thomas Mydhley, brought “miracle substance” and gave him the name “Freon”. Later engineers who were engaged in industrial production of gas introduced Freon-12 designation as «R» (in translation «Refrigerant» stands refrigerant or coolant). The second date with the advent of Freon link nepravlno as early as 1930, the company was founded Kinetic Chemical Company, whose activities had to be directed to the production of this product.

Freon – is that?
A mixture of ethane and methane as fluorinated derivatives of low molecular weight hydrocarbons where hydrogen atoms may be replaced by fluorine, chlorine, bromine. Widely used in refrigerators (refrigerators, freezers, air conditioners and so on. N). Many wonder, freon – a gas or a liquid? Correct answer: the substance may have and both physical state.
The most common types of Freon
Science has known for more than 40 types of substances, most of which goes to industrial way. The temperature of refrigerant at which it boils, each species has its own:

R11 – tryhlorftormetan (t boil 238 ° C).
R12 – Difluorodichloromethane (t boil and equipment -298 ° C).
R13 – CHLOROTRIFLUOROMETHANE (t boil and equipment -815 ° C).
R14 – tetraftormetan (t boil and equipment -128 ° C).
R134A – tetraftorэtan (t boil and equipment -263 ° C).
R22 – Chlorodifluoromethane (t boil and equipment -408 ° C).
R600A – isobutane (t boiling equipment -1173 ° C).
R410A – hloroftorokarbonat (t boil and equipment -514 ° C).
Typically, home refrigerators running on Freon (refrigerant) marks R-22 industrial and trade mark use R-13.

Freon – is a dangerous substance for humans?
Almost all kinds of substances have negative boiling point, so it is used in the cooling elements appliances like pushing element in gas cans, air fresheners and other aerosols. So when spraying himself balloon cools and the refrigerant into the air. If no refrigerant heat to 250 degrees (at a temperature out toxic substances), it is absolutely harmless to humans, that is not the ozone layer. Products decay destroy it. The main reason for the formation of the ozone hole is the production and use of freon high in chlorine and bromine ions. The leak of the substance to home appliances to visually detect smell and can not, small doses on humans have no influence.

To restore the ozone layer and reducing the production of harmful CFCs UN countries signed and ratified the Montreal Protocol.
What is the freon in refrigerators?
Modern compressor refrigerators are in the form of cameras placed inside the evaporator, which includes a refrigerant. This substance is boiling and evaporation takes heat from the chamber and in the process of condensation transmits it to the environment. This air is cooled to the required temperature, and the gas returns to the compressor and changes its aggregate state to liquid. Freon in the refrigerator is just in the evaporator. In other words, it is an important component of the system, due to which there is a cooling refrigeration chambers.

How to understand the leakage of refrigerant from the refrigerator
It is clear that this matter – one of the main components of a functioning technology. Freon leak causes damage to vehicles and the inability to use it for other purposes. The most common cause of this problem – the evaporator tube damage or plant waste. As this volatile gas is odorless, it is impossible to identify the olfactory receptors.
However, there are some signs which can determine the leak. Freon in the refrigerator is under pressure, and when the damaged tube evaporator, it is beginning to fall. Consequently, in the refrigerator and the freezer temperature rises, and the products begin to rapidly deteriorate. This is the first sign that you should check the integrity of the cooling system of the device. As mentioned earlier, the refrigerant is not dangerous to humans at temperatures above 250 degrees, and heat it to a temperature at home is impossible.
The most common refrigerant leak
First of all – this pipe joints. In any solder cracks can form as long because of the equipment and k and because of factory defects. Also common is refrigerant leakage in places connecting tubes evaporator refrigeration and freezers. Sealing can be found on the back and highways connecting the heart and refrigerator evaporator.

How to repair the leak?
Filling freon refrigerator at home without professional assistance impossible. As for the need of special equipment and materials (vacuum pump, soldering torch, dispenser collector with pressure, the metal for soldering, special flux). To identify tightness tubes using a special device that resembles a metal detector. Once the wizard detects the location of damage and zapayaet this area, eliminating leakage, vacuum pump pumped gas remaining and dressed again. Filling occurs by connecting the gas cylinder to the nozzle located on the refrigerator compressor housing through a capillary tube, sealed connection implemented key.

After that the refrigerant in the refrigerator again begins to circulate properly and the temperature in the chambers is in accordance with the standards for refrigeration devices.
