How to detect refrigerant

no matter what to buy our products, hope to buy high quality and low price, the refrigerant is not exceptional also, here is a small make up of testing the performance of refrigerants for you some relevant information, recommended by the following method to distinguish whether is inferior refrigerant:

1, whether to buy refrigerant through the national standard whether is normal manufacturer and legal channels, such as price significantly lower than the market price of refrigerants, should attach great importance to.

2. If you have any test conditions, it is recommended to use before the refrigerant impurities in the test and acidity, significantly lower than the industry standard for the test result of refrigerant is not recommended. Note: qualified purity of R22 refrigerant should be greater than ninety-nine percent ( Refrigerant should be greater than ninety-nine percent purity. 8) , acidity, In HCL) Should be less than 0. 0001.

3, if you don't have the refrigerant test conditions, it is recommended to use simple inspections before the refrigerant can, simple inspection method is:

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, refrigerants have quality problems, suggested to give up the use of the refrigerant;

then good refrigerant cylinder pressure manometer detection, control the refrigerant temperature and pressure characteristics, test whether the pressure in the bottle in the normal range, such as stress significantly higher or lower than normal value is not recommended. When long time use or used as refrigerant in the entrees, for repeated testing the pressure in the bottle.

for R22 which single refrigerant without a large number of auxiliary components, two bottles of pressure measurement value is very close, if the quality of the refrigerant is not strong, often mixed with a variety of ingredients, refrigerant in bottle after using for a long time due to the change of composition usually there will be a bigger difference, the pressure in the bottle if encounter this kind of phenomenon, suggest to immediately stop using the refrigerants, and would like to have filling to the system's refrigerant emissions clean to prevent the system from contamination.

in the process of system operation, abnormal high and low pressure or temperature (or stop state system balance abnormal pressure Can be compared to the refrigerant temperature and pressure characteristics) If there is a quality problem, need to pay attention to refrigerant.

once found caused by the chemical pollution caused by inferior refrigerant compressor fault, unit parts or so at the scene the unit of refrigerant used in the source system ( Even if the unit can work normally) Also need to change the refrigerant. Because of the effect of dangerous chemicals in the inferior refrigerant is controlled by the time, may result in system failure after a long time.

However, with the increased prevalence of refrigerant gas, it has become far more affordable.
