Attention Of R507A Refrigeration Technical Indicators

Comments · 163 Views

Therefore, if the moisture exceeds the standard in r507a refrigeration, under the catalysis of metals, the moisture in the refrigeration system will react with the refrigerant (hydrochloric acid and hydrofluoric acid),

 

   How does the "corrosion compressor" that everyone usually say happens, and how can we avoid it?

      The process of corrosion is more complicated, and there are many chemical reactions. Since moisture freezes in the evaporator, it affects cooling efficiency, and once it comes in contact with the refrigerant, it will accelerate its decomposition and corrode equipment. Therefore, if the moisture exceeds the standard in r507a refrigeration, under the catalysis of metals, the moisture in the refrigeration system will react with the refrigerant (hydrochloric acid and hydrofluoric acid), thereby causing corrosion to the compressor. Corrosion will greatly reduce the life of the compressor, or even scrap it soon, causing considerable losses to users.

      For example, the chemical stability of refrigeration oil is insufficient, and the thermal stability is too low. As we said just now, the maximum compression temperature of the compressor is very high, which can reach 130-160 degrees. In such a high temperature state, the refrigeration oil will be thermally decomposed into carbon deposits, which will cause the compressor to wear out. The oil decomposition product will chemically react with the refrigerant to reduce the cooling effect, and the acidic substances produced at the same time will cause strong corrosion to the compressor.

      In addition to the above problems, what technical indicators should we pay attention to?

      The content of paraffin should also be noted. In the process of use, the mixture of refrigerant and mineral oil-based refrigeration oil will produce paraffin and other insoluble substances to precipitate, and precipitate at a temperature higher than the freezing point. If the paraffin content in the refrigeration oil is too high, it will cause the cooling system and refrigeration pipelines. The blockage is very dangerous.

      According to these indicators, how do we identify and purchase refrigeration oil?

      Generally, consumers can judge according to the following important indicators when purchasing, so as to avoid unnecessary losses as much as possible.

      Insufficient viscosity of refrigeration oil

      Excessive moisture

      High paraffin content

      Insufficient chemical and thermal stability

      Flash point too low and pour point too high

      Deviations in these indicators are the main factors that commonly cause application failures. Regardless of the use process of refrigeration oil, once there is a mistake in the purchase process, it may lead to heavy losses. It seems that the frozen oil of wholesale fluorine solvent seems to be a trivial matter, but in fact it cannot be underestimated.
