Abstract:The use of compressors that supply with the need for compressed air is becoming more common in industry and domestic refrigerators. Many studies have been done in this field to increase the efficiency of compressors and it is still ongoing. In this study, it is aimed to increase the performance of the novel vane micro compressor, which consists of three main parts: body, rotor and vane, with the changes made in the vane. In this context, crescent vane made of steel are produced with powder metallurgy (aluminum Al 5083) and covered with hard anodized. Surface hardness measurements were made before and after the coated vanes. And vane surface roughness measurements were done before and after compressor pressure performance tests. It is seen that the surface roughness gives 5-6 times better results compared the coated vanes to the uncoated vanes. 5 sets of experiments were made for the performance tests of the micro compressor, and pressure, ampere and volt values were measured. According to the results of the experiment, it is seen that the steel vane consumes 10% higher power than aluminum vanes. In addition, the pressure of 5 bar reached on the steel vane, which is considered as a reference, was achieved with an anodized coated AL5083 crescent vane. It has been determined that the anodic coated AL5083 crescent vane, which has the same pressure value as steel and has higher surface abrasion resistance than non-coated aluminum, contributes to the performance of the crescent vane micro compressor.
