<P>PROBLEM TO BE SOLVED: To obtain a refrigerating air conditioner that reduces frictional resistance to be generated when an expander is started, and stably starts the expander. <P>SOLUTION: The refrigerating air conditioner 100 includes: a first bypass pipe 9 for bypassing an expansion mechanism 2; a first decompression unit 10 and a second decompression unit 11 which are arranged on the first bypass pipe 9; a first opening/closing unit 13 arranged on a suction-side pipeline of an auxiliary compression mechanism 3; a second opening/closing unit 14 arranged on a discharge-side pipeline of the auxiliary compression mechanism 3; and a connection pipe 12 having one end connected to a pipeline between the first decompression unit 10 and the second decompression unit 11 and the other end connected to another pipeline between the first opening/closing unit 13 and the auxiliary compression mechanism 3. The expansion mechanism 2 and the auxiliary compression mechanism 3 are integrated to achieve back-to-back double sided scroll where one base plate is shared by a rocking scroll of the expansion mechanism 2 and another rocking scroll of the auxiliary compression mechanism 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
