Compression system

Abstract

Provided is a compressor system. The compressor system includes: compressors receiving a first fluid from outside and compressing the first fluid; a motor receiving an electric current from outside to drive the compressors; a gear unit for connecting the compressors to the motor; a turbine generating a driving power from a second fluid that has exchanged heat with the first fluid that is discharged from the compressors; and a connection unit directly connected to the turbine and the gear unit.

1 . A compressor system comprising:
 a compressor receiving a first fluid from outside and compressing the first fluid;   a motor receiving an electric current from outside to drive the compressor;   a gear unit for connecting the compressor to the motor;   a turbine generating a driving power from a second fluid that has exchanged heat with the first fluid that is discharged from the compressor; and   a connection unit directly connected to the turbine and the gear unit.   
     
     
         2 . The compressor system of  claim 1 , further comprising a thermal exchanger, in which the first fluid discharged from the compressor and the second fluid exchange heat, for supplying the second fluid that has exchanged the heat to the turbine. 
     
     
         3 . The compressor system of  claim 2 , wherein a plurality of the compressors and a plurality of thermal exchangers are provided, and each of the plurality of thermal exchangers is arranged on a flow path through which the first fluid discharged from each of the plurality of compressors passes. 
     
     
         4 . The compressor system of  claim 2 , further comprising a condenser for condensing the second fluid discharged from the turbine. 
     
     
         5 . The compressor system of  claim 4 , further comprising a pump for supplying the second fluid discharged from the condenser to the thermal exchangers. 
     
     
         6 . The compressor system of  claim 4 , wherein the condenser receives cooling water from outside, and condenses the second fluid through heat exchange between the second fluid and the cooling water. 
     
     
         7 . The compressor system of  claim 1 , wherein the turbine comprises:
 a case in which the second fluid is introduced; and   a blade provided in the case and rotating according to a flow of the second fluid supplied in the case.   
     
     
         8 . The compressor system of  claim 7 , wherein the blade rotates at a constant speed. 
     
     
         9 . The compressor system of  claim 1 , wherein the gear unit comprises:
 a first gear rotating in direct connection with the motor;   a second gear provided on a rotating shaft of the compressors and rotating in connection with the first gear; and   a third gear provided on the connection unit and rotating in connection with the first gear.   
     
     
         10 . The compressor system of  claim 1 , further comprising a gear box provided to surround at least a part of the gear unit and the connection unit. 
     
     
         11 . The compressor system of  claim 1 , wherein the compressors comprise:
 a first compressor operating according to movement of the first fluid introduced from outside; and   a second compressor rotating coaxially with the first compressor and operating by receiving the first fluid discharged from the first compressor.   
     
     
         12 . The compressor system of  claim 1 , further comprising a guide vane for controlling an amount of the first fluid introduced into the compressors. 
     
     
         13 . The compressor system of  claim 1 , further comprising a control valve for controlling an amount of the second fluid supplied to the turbine.
