< p > agent is the blood of the high low temperature test chamber compressor, refrigerant purity of high and low for a high low temperature test chamber compressor is particularly important, the most obvious is like: filling the high purity of the refrigerant equipment, refrigeration effect is obvious, the temperature drop aging fast, refrigerating capacity;
Lower purity of refrigerant not only of any drop in temperature, but also will damage the compressor.
We can use the following method to distinguish whether for inferior refrigerant: < / p > < p > < / p > < p > 1, whether through formal channels to purchase normal manufacturer production of refrigerants, such as price significantly lower than the market price of refrigerants, should be on high alert.
< / p > < p > 2. If you have any test conditions, it is recommended to use before the refrigerant to test its purity and acidity, significantly lower than the industry standard for the test result of refrigerant is not recommended.
< / p > < p > 3, if you don't have the refrigerant test conditions, it is recommended to use simple check, before the refrigerant can simple inspection method is: < / p > < p > (
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, quality of refrigerant, is not recommended;
Connect 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.
< / p > < p > < / p > < p > if you are not through formal channels for purchase of refrigerant, can through the brand's official website to query the authenticity, and counterfeit refrigerants will not only influence the refrigeration effect, serious or affect the normal use of equipment.
