Summer will make our temperature higher. If we are indoors, we must have air conditioning to help us. The air conditioner can be cooled, which will bring us a feeling of refreshment. In the winter, the air conditioner can bring us warmth. Therefore, air conditioning is an indispensable electrical appliance in our lives. Everyone must know that air conditioning is filled with fluoride . If you don't know it yet, let's take a look at the Xiaobian of the decoration home network!
First, the necessity of air conditioning for fluorine
Freon is a medium for transferring heat in air conditioning refrigeration systems. Without it, heat cannot be exchanged efficiently. Air conditioning is also not possible to cool or heat. Therefore, once the air conditioner is deficient in fluorine, the external performance shows poor cooling (heat) effect, no cooling (heat), protective shutdown, indoor unit leakage (sometimes water spray), internal machine evaporator icing, etc. There are more problems that cannot be seen on the surface - reducing the service life of air conditioners, wasting power, and damaging air conditioner compressors. Therefore, in order to use air conditioners normally, there must be enough flon.
Second, the air conditioning method of charging fluorine
1. The tracheal valve is dry and has no obvious cool feeling when touched by hand. The reason is that the shortage of refrigerant causes the boiling end point in the evaporator to advance, the refrigerant of the valve is excessively increased, and the temperature of the valve rises, which is greater than the temperature of the leak point of the outdoor air.
2. The liquid pipe valve is frosted. The reason is that "deficient fluorine" causes the pressure in the liquid pipe to drop, and the boiling point is lowered, so that the valve temperature is lower than the freezing point.
3. Open the indoor unit panel and remove the filter. You can find some evaporator condensation or frost. The reason for this is that due to insufficient refrigerant, only a part of the evaporator has a boiling heat absorption, so that the cooling area is correspondingly reduced.
4. There is no thermal sensation in the outdoor unit. The reason is that the refrigerant is insufficient, the condensation pressure and the condensation temperature are lowered, and the exhaust air temperature is also lowered.
5. The drain hose drain is intermittent or not drained at all. The reason is that the evaporator cooling area is reduced, the dew condensation area is also reduced, and the amount of condensed water is reduced.
6. The outdoor engine gas and liquid valves are oily and there is leakage of oil. The reason is that the refrigerant has a certain mutual solubility with the refrigerating oil, and the fluorine escapes from the leak point and enters the atmosphere, and the oil adheres around the leak point.
7. The operating current of the air conditioner is less than the rated current. The reason is that the refrigerant is insufficient to reduce the compressor load and the current is lowered.
8. The pressure measured from the outdoor unit's filling port is less than 0.45Mpa. The reason is that insufficient refrigerant causes a drop in evaporation pressure.
Third, air conditioning and fluoride precautions
If it is a repaired air conditioner, the control system and the actuator must be normal; the pipeline system must have been effectively excluded from air, moisture, obstruction, leakage, etc.; the filter, internal and external heat exchangers should be clean and well ventilated.
Note that when adding fluoride, when starting to add, you need to invert the fluorine bottle. The time of one inversion should not be too long. Always observe the cold air temperature of the pressure gauge and air conditioner to avoid negative effects caused by excessive fluoride in one time.
Fourth, excessive fluoride treatment
If there is too much fluoride, the air conditioner will have poor cooling or no cooling at all, but some special air conditioners will have other situations. Otherwise, some models of Changhong air conditioner will increase the current of the compressor and cause overcurrent protection. .
1. Recycling to the fluorine bottle to open the heating, such as the addition of fluorine, because the thick tube is high pressure at this time, so Freon will return to the fluorine tank, it is recommended to use water to immerse the fluorine tank (this method is a little dangerous) Reminder: This method is a bit Dangerous, but very environmentally friendly, this method is not recommended here.
2. Directly let go of the high-pressure pipe valve that opens the air conditioner, and the refrigerant will automatically leak out.
The above is the method of air conditioning charging for the air conditioners compiled by everyone. If you have other decoration consultations, please continue to pay attention to the decoration home network.
