         8 . The refrigerator according to  claim 4 , wherein the cabinet supply duct and the cabinet recovery duct comprise cabinet duct guide parts that are inclined or rounded to guide movement of cool air at ends of the cabinet supply duct and the cabinet recovery duct. 
     
     
         9 . The refrigerator according to  claim 1 , wherein the ice compartment duct has an ice compartment inner opening exposed toward an inside of the ice compartment and having a vertical length less than that of the ice compartment duct opening. 
     
     
         10 . The refrigerator according to  claim 1 , wherein the ice compartment duct has a horizontal width gradually increasing from the ice compartment duct opening of an outside of the ice compartment to an ice compartment inner opening exposed toward an inside of the ice compartment. 
     
     
         11 . The refrigerator according to  claim 10 , wherein the ice compartment duct opening and the ice compartment inner opening have the same area as each other. 
     
     
         12 . The refrigerator according to  claim 1 , wherein the ice compartment duct comprises an ice compartment duct guide part that is inclined or rounded to guide a direction of cool air guided by the ice compartment duct. 
     
     
         13 . The refrigerator according to  claim 1 , further comprising heaters disposed around an inlet and outlet of the cabinet duct,
 wherein the heaters are disposed in a region except a front end of the cabinet duct opening.   
     
     
         14 . The refrigerator according to  claim 1 , wherein the cabinet duct opening has a vertical length greater than that of the ice maker.
