Refrigerator having cold air generating compartment and machine room positioned at upper portion of cabinet

A refrigerator comprising:

• a cabinet;
• a storage compartment defined by the cabinet and having a top surface that defines a top of the storage compartment, the storage compartment comprising a freezing compartment and a refrigerating compartment separated by a partition wall and arranged side-by-side in parallel;
• a cold air generating compartment that is positioned at an upper portion of the cabinet and that is in communication with the storage compartment, the upper portion of the cabinet being located at a vertical position that is higher than the top surface of the storage compartment;
• a machine room positioned at the upper portion of the cabinet and adjacent the cold air generating compartment, the machine room comprising:
• a first machine compartment provided on one side of the cold air generating compartment, wherein a condenser is installed in the first machine compartment;
• and
• a second machine compartment provided on the other side of the cold air generating compartment, wherein a compressor is installed in the second machine compartment;
• an evaporator provided in the cold air generating compartment and configured to generate cold air supplied to the storage compartment;
• a first cold air outlet positioned between the cold air generating compartment and the freezing compartment and configured to guide cold air generated by the evaporator toward the freezing compartment;
• a second cold air outlet positioned between the cold air generating compartment and the refrigerating compartment and configured to guide cold air generated by the evaporator toward the refrigerating compartment;
• a first closable damper positioned in the first cold air outlet and configured to control supply of cold air generated by the evaporator through the first cold air outlet to the freezing compartment;
• a second closable damper positioned in the second cold air outlet and configured to control cold air generated by the evaporator through the second cold air outlet to the refrigerating compartment;
• a first cold air fan located in the first cold air outlet and configured to move cold air generated by the evaporator through the first cold air outlet and into the freezing compartment;
• a second cold air fan located in the second cold air outlet and configured to move cold air generated by the evaporator through the second cold air outlet and into the refrigerating compartment;
• a first return duct that connects the freezing compartment with the cold air generating compartment and that is configured to guide air from inside of the freezing compartment toward the cold air generating compartment;
• a second return duct that connects the refrigerating compartment with the cold air generating compartment and that is configured to guide air from inside of the refrigerating compartment toward the cold air generating compartment;
• a first cold air inlet provided in a left side wall of the cold air generating compartment and connected with the first return duct to draw cold air having passed through the freezing compartment;
• a second cold air inlet provided in the right side wall of the cold air generating compartment and connected with the second return duct to draw cold air having passed through the refrigerating compartment;
• a first return damper positioned in the first cold air inlet and configured to control air flow through the first return duct;
• and
• a second return damper positioned in the second cold air inlet and configured to control air flow through the second return duct,
• wherein the first return duct is arranged along a left side wall and a top wall of the freezing compartment and the left side wall of the cold air generating compartment, the left side wall of the freezing compartment defining a left side of the freezing compartment and extending from a rear wall of the freezing compartment to a front of the freezing compartment, and
• wherein the second return duct is arranged along a right side wall and a top wall of the refrigerating compartment and the right side wall of the cold air generating compartment, the right side wall of the refrigerating compartment defining a right side of the refrigerating compartment and extending from a rear wall of the refrigerating compartment to a front of the refrigerating compartment.
