How to identify fake and shoddy refrigerants in the high and low impact test chambers

Refrigerant is the blood night of the high and low impact test chamber refrigeration compressor, the high and low purity of the refrigerant is crucial for the high and low impact test chamber refrigeration compressor, and the significant present seems to: the machine and equipment filled with high purity refrigerant, the refrigeration is actually significant, the temperature reduction timeliness is fast, and the air conditioning refrigeration capacity is large; Low purity refrigerants not only fail to achieve the required reduced temperatures, but also damage the refrigeration compressor
.
People can identify whether it is a fake and shoddy refrigerant according to the following categories: 1.
Is it a refrigerant manufactured by a reliable manufacturer according to the website, such as a refrigerant whose price is significantly less than the price of the market, should cause a height-to-width ratio alert; 2.
If you have an inspection standard, it is proposed to test the purity and acid value of the refrigerant before applying it, and the refrigerant for which the test result is significantly less than the standard is not proposed to be applied; 3, if you do not have refrigerant inspection standards, it is proposed to carry out simple inspection before the application of refrigerant, simple inspection methods: a.
the refrigerant tank is reversed, and release a small amount of refrigerant to a white paper, if there is significant residue or liquid water on the thin paper, indicating that the refrigerant quality is not good, do not propose to apply; b.
the air pressure gauge to detect the refrigerant bottle pressure, compare the refrigerant temperature working pressure characteristic table, detect whether the working pressure in the bottle is in the standard value range, such as the working pressure is significantly abnormal, it is not proposed to apply
