<P>PROBLEM TO BE SOLVED: To provide a heat exchanger integral type compressor with built-in accumulator in which a function of accumulator is added and a heat exchanger is integrally provided. <P>SOLUTION: This compressor has a double structure in which an inside closed container 1 is provided inside an outside closed container 16. In the inside closed container 1, an electric motor part 2 and a rotary compression part 3 comprised of a first-stage rotary compression part 3a and a second-stage rotary compression part 3b driven by the electric motor part 2 are provided. An intake pipe 13 is arranged within a space S between the outside closed container 16 and the inside closed container 1, and is connected to the first-stage rotary compression part 3a, and a small-sized intake pipe 13a and a delivery pipe for delivering a refrigerant gas to an outside are arranged to the second-stage rotary compression part 3b. A return pipe 18 is connected to an upper part of the outside closed container 16, and the heat exchanger 17 is mounted to an outer peripheral part. An end of the return pipe 18 is connected to an outlet of an evaporator, an end of the delivery pipe 14 is connected to an inlet of a gas cooler, an inlet of the heat exchanger 17 is connected to an outlet of the gas cooler, and an outlet of the heat exchanger 17 is connected to an expansion valve. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
