これらの混入を完全に防止することは困難であυ、また
組立後に空気や水分が混入することも考えられる。In recent years, refrigeration compressors have become smaller and more sophisticated, and as the compressors have become more compact, the conditions for using refrigeration oil have also become stricter. As a result, even if high-quality refrigeration oil was used, malfunctions occurred due to deterioration of the refrigeration oil. Factors contributing to the deterioration of this refrigerating machine oil include thermal deterioration due to overheating, generation of acid content due to mixing of air, and generation of free water due to mixing of moisture. In particular, the above acid content and moisture cause not only deterioration of the refrigerating machine oil itself, but also deterioration of the refrigerant, formation of cracks and gratings, burnout of the motor insulating material, corrosion of various parts, etc. For this reason, in the past, care was taken to prevent air and moisture from getting into the refrigeration compressor during assembly.
It is difficult to completely prevent these contaminations, and it is also possible that air and moisture may be mixed in after assembly.
本発明は以上の事情にもとづいてなされたもので、その

The goal is to provide equipment.

のである。That is, in the present invention, an adsorbent formed by dispersing powder particles of a silica gel/alumina adsorbent in a cellulose resin is housed in a refrigerating machine oil distribution section of a refrigerating compressor. Therefore, the acid and moisture mixed into the refrigerating machine oil are adsorbed by this adsorbent, so deterioration of the refrigerating machine oil can be effectively prevented and the durability of the refrigerating compressor can be improved.

In the drawing, 1 is a refrigeration compressor, and the refrigeration dry oil distribution section in the refrigeration compressor 1, for example, inside the crankcase 2, is adsorbed. As shown in FIG. 2, this adsorbent 3 contains a granular silica kel/alumina adsorbent 4 with a powder diameter of 0.5 to 2.0 in a cellulose resin, for example, cellulose acetate resin 5. The mixture ratio of the adsorbent 4 and the cellulose l!l fat 5 is selected from the range of 1=5 to 5:1 in terms of volume ratio.

、水分の吸着効率が低下することはない。One of the embodiments of the present invention constructed as described above is that acid and moisture mixed in the refrigerating machine oil are efficiently adsorbed by the straightening body 3, so that deterioration of the refrigerating machine oil is prevented and the refrigerating compressor 1 The durability of is improved. Further, since the silica shell/alumina adsorbent 4 is dispersed in the cellulose resin 5, particles of the adsorbent 4 do not float in the refrigerating machine oil and do not prevent lubrication. In addition, cellulose-based 41'a fat has good liquid compatibility and is hydrophilic, so even if the adsorbent 4 is dispersed in this resin, the adsorption efficiency of acid and moisture will not decrease.

It turned out that it is preferable that it is below t. For example, silica dal/
When 1.5 layers of alumina-based adsorbent were added and brought into contact with oil in an immersed state, the relationship between the distribution, water adsorption efficiency, and viscosity was determined, and the results shown in Figure 3 were obtained. Furthermore, the third

Therefore, it is preferable that the refrigerating machine oil brought into contact with the adsorbent 3 has a viscosity in the low viscosity range.
