Abstract

PURPOSE: To make convection of cold be conducted positively and thereby to make a temperature distribution in a third chamber uniform by a constitution wherein an intake of this chamber subjected to a temperature control different from the one for a freezing chamber and a refrigerating chamber is provided in the inside lateral wall of the third chamber and a return duct of the third chamber is made to communicate with the return duct of the refrigerating chamber. CONSTITUTION: A return duct 23 of a third chamber 3 provided in the lateral wall of the third chamber subjected to a temperature control different from the one for a freezing chamber 2 and a refrigerating chamber 4 is made to communicate with a return duct 22 of the refrigerating chamber through a side duct. Cold air cooled down by a cooler is discharged into the third chamber 3 from a discharge port provided in the ceiling of the chamber and flows in circulation to the cooler through the return duct 23 of the third chamber and the return duct 22 of the refrigerating chamber from an intake 26a provided in the inside lateral wall of the chamber. According to this constitution, return air of the third chamber is induced by the return air of the refrigerating chamber in a large circulation amount, also in this part in the right and the left inside the third chamber. Thereby convection of cold is conducted positively and a temperature distribution is made uniform.
