What is an air conditioning refrigerant? How often is the air conditioner refrigerant added?

Air conditioners have almost become the necessary household appliances for every family, but air conditioners often occur without cooling or heating. This is generally caused by the lack of refrigerant in air conditioners . So what is air-conditioning refrigerant ? How often is the air conditioner refrigerant added? Let's take a look at the decoration home decoration network Xiaobian.

What is an air conditioning refrigerant?

The air conditioning refrigerant is the working medium of the air conditioning refrigeration cycle. The refrigerant absorbs heat when vaporized in the evaporator, and the heat release cycle reciprocates when the condenser is condensed to achieve the purpose of cooling. There are more than 80 substances currently available as refrigerants, the most commonly used being ammonia, freons, water and a few hydrocarbons.

What types of air conditioning refrigerants are there?

At present, there are two types of refrigerants used in air conditioners, one is R22 refrigerant and the other is R410A new refrigerant. R22 refrigerant is commonly known as chlorofluorocarbon. It is also the refrigerant used in most air conditioners in China. It has serious damage to atmospheric ozone and will be completely banned by 2020. The refrigerants used in air conditioners of internationally renowned brands are R410A new refrigerants, which have no damage to the atmosphere and are more environmentally friendly. Therefore, it is better to use R410A new refrigerant as the refrigerant for air conditioners.

What is the principle of air conditioning refrigerant?

When the air conditioner is in the cooling operation, the low-temperature low-pressure refrigerant gas is pressurized by the compressor and becomes a high-temperature high-pressure refrigerant gas. The high-temperature high-pressure refrigerant gas passes through the condenser (generally, the air conditioner is air-cooled, that is, the outdoor unit is cooled. The copper tube) releases heat in the outdoor heat exchanger and becomes a medium-temperature high-pressure liquid (heat is taken away by the outdoor circulating air), and the medium-temperature high-pressure liquid is then subjected to capillary expansion and depressurization to become a low-temperature low-pressure liquid, a low-temperature low-pressure liquid. The refrigerant passes through the evaporator (indoor copper tube) and evaporates to become a low-temperature and low-pressure gas (the indoor air is cooled and cooled through the surface of the heat exchanger to achieve the purpose of lowering the indoor temperature), and the low-temperature and low-pressure refrigerant gas is again Compressor suction, so cycle. In general, air conditioning refrigerant is a cycle of compression-condensation-expansion-evaporation within the air conditioning system.

How often is the air conditioner refrigerant added?

Many people think that air-conditioning refrigerants must be added once a year. This view is not correct, or it is a bit biased to understand. A well-sealed air conditioner will not lose a little refrigerant in a few years, and the cooling effect is still very good, so you don't need to add refrigerant. Only when the machine starts to have poor cooling performance, you need to contact the maintenance personnel to add some air conditioning refrigerant. Don't blindly believe that the so-called one year must be added once, this is unreasonable.
