How to judge whether the central air conditioner is short of refrigerant?

The poor cooling effect of central air-conditioning system during use is the most common problem encountered by ordinary users. The direct manifestation of fluorine deficiency is also this phenomenon, but fluorine deficiency is not the only reason for the poor cooling effect of central air-conditioning , Then is there any intuitive way to judge whether the central air conditioner is fluorine-deficient? Let me tell you, first we turn on the air conditioner and let the air conditioner compressor run continuously for 30 minutes. If the refrigerant.com/hfc-refrigerant' target='_blank'>refrigeration system is short of fluorine, the following phenomena will occur.

1. The tracheal valve is dry.

There is no obvious cooling sensation when touched by hand. This is because the lack of fluorine leads to a decrease in the boiling point of the refrigerant in the evaporator, which increases the heat of the refrigerant in the valve and the temperature of the valve.

2, the liquid pipe valve is frosted.

This is because the lack of fluorine causes the pressure in the liquid pipe to drop, and the boiling point decreases, making the valve temperature lower than the freezing point.

3. Open the indoor unit panel and remove the filter, you can find that only a small part of the evaporator is frosted.

This is because the lack of fluorine leads to insufficient refrigerant and the corresponding reduction in cooling area.

4. There is no heat in the exhaust air of the outdoor unit.

This is because the lack of fluorine leads to insufficient refrigerant, which leads to a decrease in condensing pressure and temperature.

5. The drainage hose has little or no drainage at all.

This is because the lack of fluorine leads to a reduction in the cooling area of u200bu200bthe evaporator, the condensation area is also reduced, and the amount of condensed water is reduced.

6. The gas-liquid valve of the outdoor unit is oily.

This is because the refrigerant and the refrigerating oil have a certain degree of mutual solubility. After the refrigerant overflows from the leakage point, the oil stains adhere to the leakage point, which also shows that the system is not well airtight. Lead to a lack of fluoride.

7. The pressure measured from the fluorine filling port of the outdoor unit is lower than 0.45MPa.

This is because the lack of fluorine leads to insufficient refrigerant and a drop in evaporation pressure.

How about it, it’s not difficult, I believe that next time you encounter such a problem, you will not be at a loss, try it, it is very effective, if it still doesn’t Yes, find a regular maintenance manufacturer to solve it, and be careful to avoid danger.
