Abstract: A compressor system includes an inlet in which fluid flows, an inlet temperature measuring part configured to measure an inlet temperature (T_in) of the fluid at the inlet, an inlet guide vane (IGV) configured to change opening degree (IGV_position) to control a flow rate of the fluid through the inlet, a compressor to compress the fluid passing through the inlet guide vane, a motor connected to the compressor to drive the compressor, and configured to change rotating speed, a discharge pressure measuring part to measure a discharge pressure (P_disch) of the fluid passed the compressor, an outlet to discharge the compressed fluid, and a check valve installed at the outlet to prevent backflow of the fluid.

Abstract: The present invention provides a scroll compressor which includes a housing, a stationary scroll including a stationary wrap, an orbiting scroll having an orbiting wrap, a receiving portion formed in the housing, a self-rotation preventing eccentric shaft installed in the receiving portion with a bearing interposed therebetween, a self-rotation preventing mechanism including a stopper formed in the housing to support the front of the bearing, and a bearing tube fixed to the housing to support a drive shaft, the scroll compressor including: an annular groove formed in the stationary scroll or in the orbiting scroll; a dust seal fitted in the annular groove and having first and second ends at both ends; and a stationary block including a first support member and first and second elastic members which extend from the first support member and face the first and second ends, the stationary block being fitted in the annular groove.
