How to correctly judge the true and false of the refrigerant, do you know?

In real life, we all know that no matter what product we buy, there are true and false, and refrigerants are no exception. So how do we judge whether the refrigerant is true or false? The following editor will introduce a few small methods for everyone, let us take a look together.

1. Turn the refrigerant tank upside down and release a small amount of refrigerant onto a piece of white paper; if there are obvious impurities or liquid water on the white paper, it means that the refrigerant is of poor quality and it is not recommended to use it.

2. Connect the pressure gauge to test the pressure of the refrigerant bottle, and check whether the pressure in the bottle is within the normal range according to the refrigerant temperature and pressure characteristic table; if the pressure is obviously abnormal, it is not recommended.

3. When the refrigerant is halfway used, test the pressure in the bottle again. For a single-component refrigerant such as R22, the two measured bottle pressure values u200bu200bshould be very close. If the refrigerant is inferior, it is usually mixed with multiple components. After the refrigerant in the bottle is used, due to the change of the composition ratio, the pressure in the bottle usually has a large difference. If such a phenomenon is encountered, it is recommended to stop the When using refrigerant, the refrigerant that has been injected into the system should be emptied in time to avoid pollution to the system.

4. In the system debugging and operation stage, if the following abnormal phenomena are found, it is recommended to check the purity of the refrigerant in the system to check whether the refrigerant discharged from the system is of poor quality.

The refrigeration capacity of the system is obviously insufficient and after inspection, no other abnormal conditions are found. The refrigerant needs to be paid attention to;

The system dryer, filter or expansion valve is clogged, and the blockage is When the yellow-brown wax-like or black sludge-like foreign matter needs to pay attention to the refrigerant;

When the system is running, the high and low pressure or temperature is abnormal, or the system balance pressure is abnormal when the system is stopped, and the refrigerant needs to be checked.

This is the end of the above introduction of refrigerants. I hope to bring you some help. If you have a demand for refrigerants, please contact us for consultation and negotiation. We will serve you wholeheartedly.
