What is the fluorine pressure of air conditioner in winter?

Generally, it should not be higher than 0.35MP in winter, and the conditions must be met when fluoride is added to air conditioners. For example, the air conditioner must meet the use conditions and installation standards specified by the manufacturer, the air conditioner control system and actuator must be normal, the pipeline system must effectively eliminate air moisture, blockage and leakage, the internal and external heat exchangers must be clean and well ventilated, and the maintenance tools and materials must be qualified.

How much fluorine should be added to the air conditioner at a time?

1. No matter what model or brand of air conditioner, the fluoride content is similar. The pressure of hydrogen fluoride is basically above 6 pressure, and in most cases 5 pressure is enough. The return air pressure of R22 refrigerant used in ordinary air conditioners is generally 0.5-0.55Mpa. In addition, the following centralized methods can be used to judge whether the refrigerant is sufficient: synchronously monitor the compressor current; Observe the condensation of the air return pipe; Feel the air temperature, etc.

2, according to the different weather and air pressure, hanging 25 degrees to 30 degrees, the outdoor environmental pressure is basically around 4.5-5kg air pressure. For example, 1.5 air conditioner, if you look at the pressure gauge, the pressure is between 0.45 and 0.6 kg, and if it is about 24 degrees, 0.45 kg is almost the same. If you say the weight, each air conditioner will indicate the weight and rated current of the air conditioner. Generally, the weight of 1.5P snow is between 0.6 and 0.9kg (referring to the weight).

3. It is good to add fluoride to the air conditioner to the right amount. Of course, you can't do without it, but you can't do without it. It won't be cold if it's too full. Is the filling amount of fluorine just enough to convert the current clamped by ammeter into the cooling capacity of air conditioner? In addition, there is a very simple method, which is to break the insulation layer of the outdoor suction pipe by 200mm to see if there is condensation when the machine is running. If there is dew, the amount of fluoride should be just right.
