Abstract

본 발명은 2단 원심압축기를 이용한 냉방 사이클에 관한 것으로서, 종래에는 증발기, 응축기, 압축기 등을 포함한 냉방 사이클에서 압축기의 흡입구로 습냉매가 유입되어 압축 성능을 저하 시키거나 또는 기액 분리기에서 증발기로 이어지는 유체관과 증발기에서 압축기 흡입구로 연결되는 유체관에서의 온도 조절 수단이 구비되어져 있지 않아 전체적인 냉방 사이클의 효율을 높이는데 제약이 있었다.The present invention relates to a cooling cycle using a two-stage centrifugal compressor. In the related art, a wet refrigerant is introduced into a suction port of a compressor in a cooling cycle including an evaporator, a condenser, a compressor, and the like, thereby reducing the compression performance or from a gas-liquid separator to an evaporator. Since there is no temperature control means in the fluid pipe connected from the fluid pipe and the evaporator to the compressor inlet, there is a limitation in increasing the efficiency of the overall cooling cycle.

본 발명은 상기예의 문제점을 제거할 수 있도록 냉매 유체 경로가 응축기(1)→기액분리기(24)→증발기(2)→2단 원심 압축기(5)→응축기(1)로 순환되는 냉매 유채의 경로와, 상기 2단 원심 압축기(5)의 전동부(6) 냉각유체가 응축기(1)→전동부(6)의 고정자 자켓공간(27)→기액 분리기(24)로 순환되는 냉각유체 경로와, 상기 기액 분리기(24)→전동부(6)측의 냉각가스 입구(7)→전동부측의 내부공간(9)→전동부측의 냉각가스출구(8)→원심 압축기 2단 압축부(37)의 2단 압축실(4)의 경로로 순환되는 냉각유체 경로를 포함하고 있는 것을 특징으로 하는 2단 원심 압축기의 냉방 사이클을 제공하는데 있다.In the present invention, the refrigerant rapeseed path in which the refrigerant fluid path is circulated from the condenser (1) to the gas-liquid separator (24) to the evaporator (2) to the two-stage centrifugal compressor (5) to the condenser (1) can be eliminated. And a cooling fluid path through which the transmission part 6 cooling fluid of the two-stage centrifugal compressor 5 is circulated from the stator jacket space 27 to the gas-liquid separator 24 of the condenser 1 to the transmission part 6. The gas-liquid separator 24 → the cooling gas inlet 7 of the transmission section 6 → the inner space 9 of the transmission section → the cooling gas outlet 8 of the transmission section → the centrifugal compressor two-stage compression section 37. It is to provide a cooling cycle of the two-stage centrifugal compressor, characterized in that it comprises a cooling fluid path circulated in the path of the two-stage compression chamber (4).
