What is the matter with air conditioner frost? What is the matter with refrigerator frost?

Whenever it is hot in summer, people will choose to turn on the air conditioner at home to enjoy the coolness, and they will also make some cold drinks in the refrigerator. This is the best way to escape the summer heat, but many people will experience frosting in the air conditioner or refrigerator. When this happens, it will greatly affect the cooling effect of the air conditioner and refrigerator and affect people’s normal life, but many people don’t know why frost occurs. So, what is the reason for frosting in the air conditioner and the refrigerator?

First, what is the reason for frosting in the air conditioner and refrigerator? Most of the time, the refrigerant cannot circulate, the heat dissipation is not good, there is not enough Freon, or other refrigerants are not enough. Add some. If the air conditioner is half frozen and the other half is not cold, it must be that there is less refrigerant or the air conditioner pipe is blocked (also called semi-blocked state), and the refrigerant cannot circulate in time. All the cold energy accumulates in the front half of the evaporator, leading to ice formation. There is another situation, that is, the indoor and outdoor units of your air conditioner do not match, the outdoor unit is larger than the indoor unit, so the indoor unit will freeze. The air volume of the air conditioner may be too small, and the cold air of the air conditioner cannot be blown out in time. After being turned on for a long time, the temperature of the indoor unit becomes lower and lower, and finally freezes. Check if the filter is blocked by dust. Please clean the internal filter as soon as possible.

Second, in the cold winter, it would be nice to turn on the air conditioner and blow some warm air. However, after turning on some air conditioners, it was found that the heating pipes of the air conditioner were frosted, and the temperature did not rise. There was even a layer of frost on the heating pipes of the air conditioner, which was puzzling. So what is the situation and how to solve the problem of frosting on the air conditioning heating pipes? Let me explain what causes frost on the air conditioner heating pipes.

What causes frosting in the air conditioner? What causes frosting in the refrigerator? Normal frosting. When the air conditioner starts running, the condensing temperature and condensing pressure are low, the capillary liquid supply is lower than normal, which causes the evaporation pressure to decrease, thus causing frost on the low-pressure liquid supply pipe. However, this frosting to melting process is only a short time. Generally, frosting begins after the compressor starts running, and the entire frosting and melting process is completed within 5 minutes, and the air conditioner enters normal operation. Fluoride deficiency. When the air conditioner lacks refrigerant, frost will form on the low-pressure liquid supply pipe, which is a typical fault phenomenon. This phenomenon is manifested in that the low-pressure liquid supply pipe begins to frost when the air conditioner starts running, and it does not disappear even after the compressor has been running for more than 10 minutes. The cause of fluorine deficiency may be a normal phenomenon for air conditioners that have been used for many years. All you need to do is add refrigerant. If the fluorine deficiency occurs in a refrigeration unit that has only been used for two or three years or has just been installed, it is caused by leakage in the refrigeration system.
