Résumé

R32 has been being one of the hot candidates for refrigerant substitute because of its better thermodynamic performance. In this study, the influence of wet compression on R32 system performance was researched by experimental test firstly. The result showed that, with the suction vapor quality decreasing, the discharge temperature and the system performance decreased simultaneously. And then, on the base of the wet compression experiment test, the experiment that the influence of the oil return hole on system performance of R32 wet compression was carried out. The experimental results showed that, in wet compression, the decreasing rate, that the cooling capacity and EER decreased with the discharge temperature decreasing, decreased with the increase of the oil return hole size. The increase of the oil return hole size was benefit to improve the system performance in wet compression. But it increased the risk of over wet compression or liquid impact for compressor under frosting and defrosting condition.
