Are you still using inferior refrigerants? You should be aware of these hazards

Everyone knows that for every refrigeration equipment, refrigerant is very important and can be said to be indispensable; with it, refrigeration equipment can achieve the effect of refrigeration, and there are currently many types of refrigerants. But there are many inferior products among them. Because of the lack of strong and responsible large enterprises in the refrigerant field for a long time, and the imperfect refrigerant sales channels in the market, some refrigerants for fish in troubled waters flood the market . Don't ignore this problem, because it will not only affect the operation and efficiency of the refrigeration system, but also cause damage to the interests of many businesses and consumers. So what are the harms of inferior refrigerants? 01. The hazards of low-quality refrigerants 1. Counterfeit refrigerants are often the products of small workshops, and all indicators fail to meet the requirements. Excessive acid ions and sulfide ions will accelerate the corrosion of refrigeration equipment. If aluminum tubes are used, the corrosion rate will be very fast. 2. The formula ratio is not accurate, and there is no precision at all. It will cause unnecessary work load and damage to the parts of the compressor. 3. The refrigerant is not used completely, causing some harmful gases to flow into the refrigeration system, and the consequences will be quite serious. 4. Excessive fluorine content in the refrigerant will cause leakage, which is very harmful to the ozone layer that humans rely on for survival. 5. Uneven quality levels are mixed with combustible gases, which can easily cause fire and explosion accidents.

02. How to identify low-quality refrigerants 1. Please be sure to purchase refrigerants produced by regular manufacturers through formal channels. If the price is significantly lower than the market price, a high degree of vigilance should be aroused. 2. If you have the test conditions, it is recommended to check the purity and acidity of the refrigerant before using it. It is not recommended to use the refrigerant whose test results are significantly lower than the industry standard. Note: The purity of qualified R22 refrigerant should be greater than 99% (the purity of high-quality refrigerant is greater than 99.8%), and the acidity (in HCL) should be less than 0.0001. 3. If you do not have the refrigerant detection conditions, it is recommended to perform a simple inspection before using the refrigerant. The simple inspection method can be: [1] Turn the refrigerant tank upside down and release a small amount of refrigerant onto a piece of white paper , If there are obvious impurities or liquid water on the white paper, it means that the quality of the refrigerant is not good and it is not recommended to use it.

[2] Connect the pressure gauge to test the pressure of the refrigerant bottle, and check whether the pressure in the bottle is within the normal range of the refrigerant temperature and pressure characteristics table. If the pressure is obviously abnormal, it is not recommended. And when the refrigerant is half used, the pressure in the bottle can be tested again. For a single-component refrigerant such as R22, the two measured bottle pressure values u200bu200bshould be very close, but for inferior refrigerants, multiple components are usually mixed. After the internal refrigerant is used, the bottle pressure usually varies greatly due to the change of the composition ratio. If such a phenomenon is encountered, it is recommended to stop the refrigerant immediately and discharge the refrigerant that has been charged into the system to avoid it. Pollution system. In order to maintain the safety and reliability of your refrigeration system, but also to maintain your business image, and to make your life safer, please stay away from fake and inferior refrigerants!
