Abstract

There are provided a two-stage compression device having two serially connected compressors, of which the number of components is reduced through omission of an oil separator, and thereby the configuration is made simpler, lower in cost, and more compact, and a chilling/air-conditioning device using the two-stage compression device. The two-stage compression device 2 which compresses a refrigerant in two stages includes two serially connected compressors of which a low stage-side compressor 10 and a high stage-side compressor 20 in which, of the two compressors 2, the low stage-side compressor 10 is a low pressure housing-type compressor 10, while the high stage-side compressor 20 is a high pressure housing-type compressor 20, and an oil sump 25 of the high pressure housing-type compressor 20 and an oil sump 15 of the low pressure housing-type compressor 10 are connected through an oil return pipe 27.
