Way to identify small R22 refrigerant of true and false

R22 refrigerant believes everyone not unfamiliar, market sales of multifarious, so we how to discern between true and false? Below small make up to you to sort out a few small methods, let's learn together.

principle analysis: the purity of R22 refrigerant CHCLF2 is a kind of pure at least above ninety-nine percent; Current market of counterfeit R22 containing monochloro methane and other highly corrosive substances, a high percentage. A the methane of cl has a strong corrosion resistance, can cause severe corrosion to the refrigeration compressor of the unit, resulting in compressor scrap.

the refrigerant tank inversion, and release a small amount of refrigerant to a piece of white paper, if there is a obvious impurity in white paper or liquid water, poor quality of refrigerant, is not recommended;

pressure gauge test refrigerant cylinder, control the refrigerant temperature and pressure characteristics, test whether the pressure in the bottle in the normal range, such as the abnormal pressure obviously is not recommended.

in the refrigerant used in the middle, can test the pressure in the bottle again, for refrigerant R22 refrigerant this single component, two bottles of pressure measurement value should be very close to, but for inferior refrigerants, often mixed with a variety of ingredients, refrigerant in bottle after use due to the change of composition usually there will be a large bottle of pressure difference, if encounter this kind of phenomenon, advice immediately stop using the refrigerants, and would like to have filling to the emissions of refrigerant in the system clean to avoid pollution system.

in the system debugging phase, if it is found that the following anomalies

1) And system refrigeration capacity obviously insufficient and through inspection found no other abnormal 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 system balance when abnormal pressure ( To control the refrigerant temperature and pressure characteristics) , need to focus on refrigerant.

warm reminder: now fraud means many small-scale operations, we purchase don't covet petty gain must buy popularity of big brand, hope the above about the introduction of R22 refrigerant can bring you some help.

Over the years, has become very popular as more and more people are trying it out.
