In summer, air conditioning usage is the highest season. However, in the hot summer, if there is a problem with the fluorine in your home air conditioner. Then, you may not be too easy to enjoy the coolness of air conditioning, and will get angry. In fact, there is no need to worry too much about this issue. This is just the most common minor problem in air conditioning use. Today, the small series of the decoration home network will come to introduce you to the air conditioning and fluoride .
First, there are cases where the following conditions need to be added to the air conditioner:
1. It has been used for more than 5 years (any split air conditioner will naturally leak Freon);
2, multiple transfer of the machine (air-conditioning transfer machine will consume part of the fluorine when it is empty);
3. The exposed portion of the thick pipe (ie the low pressure pipe) at the connection point of the foreign machine in summer is not dew or cold;
4, the summer outside machine fan is not hot;
5, summer return pressure (thick tube) is less than 0.4 MPa;
6. The running current of the compressor is less than the normal value marked on the nameplate;
7. Summer high-pressure pipe (thin pipe) frosting;
8. In summer, the air conditioner is icing or blowing fog (sometimes accompanied by internal water leakage);
9, the winter hand touches the outer tube copper pipe interface at the thick pipe is not hot;
10. The air conditioner has a leak point;
11. The air conditioner will be shut down after ten minutes (low voltage protection or overheat protection).
Second, air conditioning and fluoride method
1. Turn on the air conditioner. In the summer, you can directly add fluorine in the air conditioning and cooling mode. There is no way to add fluorine in the heating state. In winter, the method of changing the valve line by hot-spinning is used to carry out the forced air-conditioning into the cooling state.
2. Connect the fluorine-added equipment. After turning on the air conditioner, the external machine mortgage valve is connected to the fluorine-added equipment, but be careful not to let the dirty things enter the fluoride-added pipeline.
3, pressure measurement and fluoride, when the summer ambient temperature is 32 degrees, the pressure is controlled at about 0.45mp; the winter pressure is stable at about 1.7mp.
4. Remove the fluorine-added equipment. In the cooling state, remove the fluorine-added equipment, and then tighten the seal of the outer machine. In the heating state, removing the equipment can cause a lot of leakage. After the addition is completed, it can be tested with detergent foam.
Third, how to determine whether the air conditioning and fluoride content is full
1. According to the reading of the pressure gauge: the low pressure is observed in summer. When the ambient temperature is about 32 degrees Celsius, the pressure is controlled at about 0.45 MP. In winter, the high pressure is controlled during heating. After the pressure is stable, the pressure is controlled at about 1.7 MP.
2, take the sound of the compressor to determine, if the air conditioning is more fluorine, its sound is more dull; if the air conditioning fluorine is still very small, then the sound will be lighter. Generally, the compressor has a normal load. If it is too much, the compressor may be damaged. If the compressor is less, the "cooling effect ratio" may be poor.
3, the most accurate way to judge the current is the way, the premise is that you have an ammeter in your home. You can use an ammeter to test the operating current of the compressor. This is ideal, and the amount of fluoride can be judged accurately. In addition, you can also determine the amount of fluorine by looking at the coolness of the indoor unit. Generally, the air outlet is between 8-15 °C.
Any appliance that has been in use for a long time will have some problems with more or less. For the air conditioning and fluoride, this is too frequent. Therefore, you don't have to worry too much. As long as you understand the above, you can judge for yourself whether your air conditioner is not cooled due to lack of fluorine. If you want to know more about decoration, please continue to pay attention to the decoration home network.
