How to add fluoride to air conditioners in winter? What are the precautions for adding fluoride to air conditioners in winter?

With the development of various technologies and the appearance of air conditioners, we have solved the problem of weather changes. It is too hot in summer. Air conditioning has solved the problem for us and brought us coolness and comfort. It is too cold in winter. Air conditioning gives us heat and makes us warmer. But fluorine in air conditioners is a very important galaxy. So how to add fluoride to air conditioners in winter? What are the precautions for adding fluoride to air conditioners in winter? The change of weather has brought many problems to our life, but with the development of various technologies and the emergence of air conditioners, we have solved the problem of weather change. It is too hot in summer. Air conditioning has solved the problem for us and brought us coolness and comfort. It is too cold in winter. Air conditioning gives us heat and makes us warmer. But fluorine in air conditioners is a very important galaxy. Then I'll introduce how to add fluorine to air conditioners in winter. What are the precautions for adding fluoride to air conditioners in winter?

How to add fluoride to air conditioners in winter?

1. Use air conditioner for refrigeration, and the sensor of the internal machine is heated by hand, so that the air conditioner can be forcibly started under refrigeration, so that fluoride can be added. When the air conditioner is fluorinated, pinch the current with an ammeter, because you can't see the actual pressure in winter! Turn on the heating state of the air conditioner, and then unplug the wiring of the four-way valve of the external machine, so that the air conditioner can be cooled, so that fluoride can be added, generally adding the pressure of 1.6-2 1 MPa.

2. It is not accurate to look at the pressure only if it is added. You have to measure the current with a clamp ammeter to see what the current is when your air conditioner is heating, and then slowly add the current to the corresponding machine. If it's too much, you have to let it go. When the machine is heating, you can also remove the power supply of the four-way valve outdoors and start adding it. In fact, no matter how fluoride is added, the air conditioner must be cooled before fluoride can be added.

What are the precautions for adding fluoride to air conditioners in winter?

1. Put the thermometer probe at the air outlet, and pay attention to the comprehensive judgment of air outlet temperature, reference pressure and current when adding fluorine.

2. The system pressure is too high, usually with high fluorine content. At this time, the heating effect is not good. When the compressor works in an overload state, the current also exceeds the rated current by a lot. If some fluorine is discharged, the air outlet temperature will rise instead.

3. If you add too much fluorine, you can put fluorine in a fluorine bottle at this time, which can reduce waste.

4. Heating mode operation, because of the high pressure in the system, when the pressure gauge is connected or removed, fluorine in the high pressure will be sprayed at the interface. If sprayed on your hands, the roots will easily freeze your hands. Before starting the pressure gauge, connect it to the three-way valve access port in advance; Unplug the power four-way valve coil, switch to refrigeration mode, and then remove the pressure gauge. In practice, cover your hands with disposable plastic bags or clean shoe covers, so that even if fluoride is sprayed on your hands, you will only feel cold and will not freeze your hands. Hands frostbitten by fluoride will blister like those scalded by boiling water.

5. When fluoride is needed for heating fault repair, the fluorine tube endothelial pad is easy to age and harden due to the cold and hot temperatures. In order to prevent hand injury and leakage of fluorine, the leather pad should be replaced frequently.

6. In order to add fluoride conveniently, it is usually necessary to unplug the four-way valve coil. Pay attention to the safety of electricity use at this time. When Hefei air conditioner is in maintenance operation, use pliers to unplug the zero-line power supply end of the four-way valve coil.

7. When heating, the pressure is high, and the fluorine tube should be of good quality and can withstand high pressure. Prevent it from bursting during maintenance, and the fluorine sprayed by high pressure will hurt people.

8. If the maintenance time is too long, when the four-way valve coil is unplugged, it may enter the defrosting state. Unplug the power plug at this time and plug it in after 3 minutes.

9. Never add fluoride in winter: switch to refrigeration mode according to refrigeration pressure. Because it is not obvious whether fluorine is more or less in cooling mode, there is a big difference after switching to heating mode.

10. If you don't pay attention to fluoride in winter, you will add more fluoride, which will reduce the heating effect in winter and the cooling effect in summer, so you should consider it in many aspects.

The above is what I introduced about how to add fluorine to air conditioners in winter. What are the precautions for adding fluoride to air conditioners in winter? We have some knowledge about fluoride addition in winter. And I also know the precautions for adding fluoride to air conditioners in winter. If you add fluoride in winter, you must pay attention to it, so as to ensure that your air conditioner can be used normally.
