ROTARY COMPRESSOR AND AIR CONDITIONER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To improve assembling work efficiency of a device such as piping while reducing an occupied area of a rotary two-stage compressor. SOLUTION: The rotary two-stage compressor is provided with a rotary compression element having a low pressure compression element and a high pressure compression element, and an intermediate passage connected to a compression chamber of the low pressure compression element and a compression chamber of the high pressure compression element and separated from the internal space of a sealed container. The outer peripheral side lower part of the sealed container is provided with three legs almost uniformly in the circumferential direction. An accumulator connected to a suction port of the low pressure compression element, the intermediate passage, and injection piping connected to the intermediate passage are provided between the adjacent legs provided at the sealed container, and installed such that the outer periphery of the accumulator is closer to the leg than that of the injection piping.
