How to correctly judge refrigerants of true and false

in real life, we all know, no matter what products to buy, there is really false, refrigerant is not exceptional also, so how to judge refrigerants of true and false? Below small make up to introduce a few methods, let's learn together.

1, the refrigerant can of inversion, and release a small amount of refrigerant to a piece of white paper; If there is obvious on the white paper impurities or liquid water, poor quality of refrigerant, suggest not to use.

2, refrigerant cylinder pressure gauge testing, control the refrigerant temperature and pressure characteristics, check whether the pressure in the bottle in the normal range; If pressure apparently unusual, is not recommended.

3, the refrigerant used in the middle, the pressure inside the bottle test again. For refrigerant R22 this single component, two measuring bottle pressure value should be close. If the refrigerant is inferior refrigerants, often mixed with a variety of ingredients, refrigerant in bottle after use due to the change of the composition proportion, usually there will be a bigger difference, the pressure in the bottle if encounter this kind of phenomenon, suggest to stop the use of the refrigerant, and should be timely to the refrigerant emptying has been injected into the system, to avoid damage to the system.

4, in the system debugging phase, if it is found that the following anomalies, suggests purity tests on refrigerant in the system, whether the discharge refrigerant in the system for the poor.

( 1) System refrigeration capacity obviously insufficient and through inspection, found no other exceptions need to focus on the condition of the refrigerant;

( 2) System dryer, filter or expansion valve block, and the blockage is tan wax-like or black sludge need to focus on refrigerant when foreign body;

( 3) Appeared in the process of system running high, low pressure or temperature anomaly, or stop state, abnormal pressure system balance, need to check the refrigerant.

the above about the end of the refrigerant is introduced here, hope to be able to bring you some help, if you have a demand on refrigerant, welcome consultation discussion with us, we wholeheartedly at your service.
