How often is it appropriate to add air conditioning refrigerant?

Air conditioning is convenient and fast for cooling and heating, and it has almost become a must-have household appliance in every family. However, the phenomenon of no cooling or heating often occurs in air conditioners, and this is generally caused by the lack of refrigerant in air conditioners. What is the refrigerant for air conditioning? Generally, netizens think that the air-conditioning refrigerant is Freon. In fact, this is one-sided. The following editor will tell you what the air-conditioning refrigerant is and how often the air-conditioning refrigerant is added.

What is air conditioning refrigerant-Overview of air conditioning refrigerant Refrigerant is the working medium of air conditioning refrigeration cycle. The refrigerant absorbs heat when vaporized in the evaporator, and in the condenser During condensation, the exothermic cycle reciprocates to achieve the purpose of refrigeration. At present, there are more than 80 kinds of substances that can be used as refrigerants, the most commonly used are ammonia, freons, water and a few hydrocarbons. At present, there are generally two kinds of refrigerants used in air conditioners, one is R22 refrigerant, and the other is r410a new refrigerant. R22 refrigerant is what we commonly call Freon, and it is also the refrigerant used in most domestic air conditioners. It has serious damage to atmospheric ozone and will be completely banned by 2020. Internationally renowned brands of air conditioners such as Samsung, Daikin, and Telin Fluorine use new refrigerants of R410A, which are non-damaging to the atmosphere and are more environmentally friendly and healthy. Therefore, air conditioners using R410A new refrigerants as refrigerants are better.

What is the refrigerant of air conditioning-the operating principle of air conditioning refrigerant When the air conditioner is in refrigeration operation, the low temperature and low pressure refrigerant gas is sucked in by the compressor and then pressurized to become high temperature and high pressure Refrigerant gas, high-temperature and high-pressure refrigerant gas passes through the condenser (generally air-cooled, that is, the heat dissipation copper pipe of the outdoor unit) radiates heat in the outdoor heat exchanger, and becomes a medium-temperature and high-pressure liquid (the heat passes through the outdoor circulating air Go), the medium-temperature and high-pressure liquid becomes low-temperature and low-pressure liquid after capillary expansion and pressure reduction. The low-temperature and low-pressure liquid refrigerant passes through the evaporator (indoor unit copper pipe) to absorb heat and evaporates and becomes a low-temperature and low-pressure gas (indoor air passes through The surface of the heat exchanger is cooled down to achieve the purpose of lowering the indoor temperature), and the low-temperature and low-pressure refrigerant gas is sucked in by the compressor and circulates in this way. In general, the air-conditioning refrigerant in the air-conditioning system is a cycle of compression-condensation-expansion-evaporation.

Schematic diagram of the air conditioning refrigeration cycle What is the air conditioning refrigerant-how often does the air conditioning refrigerant be added? Many people think that Freon must be added once a year. This view is not correct. In other words, understanding the above is still a bit biased. Air-conditioning with good airtightness will not lose a little Freon for a few years, and the cooling effect is still very good. Therefore, you do not need to add Freon. Only when the machine starts to show poor cooling effect, do you need to contact maintenance personnel to add some Freon. Don't blindly believe the saying that it must be added once a year. This is unscientific.

What is the air-conditioning refrigerant? Generally speaking, the air-conditioning refrigerant is Freon and R410A new refrigerant. Nowadays, technologically advanced air-conditioners use R410A new refrigerant as the refrigeration system. Air-conditioning refrigerant does not need to be added frequently. As long as the air-conditioning system has good air-tightness, it can be omitted for several years. Only when the machine starts to show poor cooling effect, then consider whether to add refrigerant.
