TURBO COMPRESSOR

摘要

PURPOSE: A turbo compressor is provided to be easily assembled with improved productivity, stability and reliability. CONSTITUTION: The turbo compressor is comprises:the 1st and 2nd impeller to compress coolant with centrifugal force; a motor chamber(113) having a sucking port(113a) communicating with an evaporator in the freezing cycle; the 1st coolant tube(180) to introduce coolant gas to the 1st compressing chamber(111); the 2nd coolant tube(190) to connect the inlet port of the 1st compressing chamber(111) and the 2nd compressing chamber(112); the 2nd coolant tube(190) introducing the coolant gas compressed in the 1st compressing chamber(111) to the 2nd compressing chamber(112) for a secondary compression there; and a driving motor(150) installed in the motor chamber(113) to produce a driving force.
