         7 . The outdoor unit of  claim 6 , wherein the shield side case further includes a third side case coupled to an upper end portion of the second side case, and wherein the shield top case is coupled to an upper end portion of the third side case. 
     
     
         8 . The outdoor unit of  claim 2 , wherein the shield rear case is disposed to face the barrier. 
     
     
         9 . The outdoor unit of  claim 8 , wherein the shield rear case forms a first side and an outer appearance of a rear surface of the shield assembly, and wherein the shield side case forms an outer appearance of a second side of the shield assembly. 
     
     
         10 . The outdoor unit of  claim 2 , wherein a locking groove is formed in the shield front case, and wherein a locking protrusion configured to be coupled to the locking groove is formed on the shield top case. 
     
     
         11 . The outdoor unit of  claim 2 , wherein the shield base includes a recessed portion, the recessed portion being a portion of a center of an upper surface of the shield base which is recessed downward, and wherein the compressor is disposed above the recessed portion. 
     
     
         12 . The outdoor unit of  claim 11 , wherein a refrigerant hole through which the refrigerant is discharged in a downward direction is formed in the recessed portion. 
     
     
         13 . The outdoor unit of  claim 11 , wherein the shield base further includes at least one refrigerant slit through which the refrigerant is discharged in a downward direction. 
     
     
         14 . The outdoor unit of  claim 13 , wherein the at least one refrigerant slit comprises a plurality of refrigerant slits spaced apart along an outer circumference of the recessed portion. 
     
     
         15 . The outdoor unit of  claim 11 , wherein the shield base further includes at least one bracket coupling portion configured to be coupled to a compressor bracket that supports the compressor. 
     
     
         16 . The outdoor unit of  claim 15 , wherein the at least one bracket coupling portion comprises a plurality of the bracket coupling portions spaced apart along an outer circumference of the recessed portion.
