Vapor compression refrigeration cycle apparatus provided with a hermetic compressor and the hermetic compressor

摘要

have the centrifugal impeller to rotate synchronously provided above the rotor, hermetic type compressor in which refrigerant flowing into the lower space flows out from the discharge pipe flows into the upper space rises rotor vents a is a centrifugal impeller, the oil separation plate provided on the upper side of the rotor, and a plurality of blades provided upright on the lower surface of the oil separation plate, it is formed between two vanes adjacent and the blade between the passage and the refrigerant flowing out from the rotor vents form a vane inner flow path leading to inside the inlet of the vane between the flow path, disposed outside the outlet of the vane between the flow passages in the entire circumferential direction, the vanes between the flow and the refrigerant that is boosted during road passing from the outer peripheral outlet intended to flow out into the upper space, the oil separation plate is disposed on the upper side of the upper surface and the blade inner flow path of the blade between flow channels, not pass the vane between channel It plugged a short route that flows out to direct the discharge pipe from the wings inside passage.
