Abstract

The present disclosure relates to a compressor including: a motor having a rotating shaft; a first impeller housing forming a first inlet, through which a first refrigerant flows, and having a chamber into which a second refrigerant flows; a first impeller coupled to one end of the rotating shaft, and rotatably received in the first impeller housing; a diffuser spaced apart from an inside of the first impeller housing, and forming a first outlet; a second impeller housing having a second inlet formed therein; a second impeller coupled to the other end of the rotating shaft, and rotatably received in the second impeller housing; a volute case in which a volute is formed; and a motor housing having a connecting passage formed therein and connecting the first outlet and the second inlet.

Description

technical field [0001] The present invention relates to a compressor and a cooling device including the compressor. More specifically, the present invention relates to a structure for efficiently flowing gaseous refrigerant discharged from an economizer into a compressor. Background technique [0002] In general, a cooling device is used to supply cold water to a cold water demand side, and is characterized in that a heat exchange is performed between refrigerant circulating in a refrigerant cycle and cold water circulating in a demand side to cool the cold water. Such a cooling device can be installed in a large building or the like as a large-capacity device. [0003] The cooling unit includes a compressor that compresses the refrigerant, and in order to increase the efficiency of a single-stage compressor that uses HFC series environmentally friendly refrigerants, namely "R134a" refrigerants, multi-stage compression that constitutes a circuit that compresses refrigerant i...
