Refrigeration unit

Abstract

The purpose of this invention is to provide a freezing device that can prevent quality degradation caused by freezing. The refrigeration apparatus of the present invention includes: a main body 10 having a refrigeration space 11h for accommodating frozen objects, a cold air generating device 13 having the function of generating cold air, and a control unit 30 for controlling the operation of the cold air generating device 13; the main body 10 includes: a circulation channel 12 configured to surround the refrigeration space 11h and circulate cold air around the refrigeration space 11h, a flow rate adjustment unit 15 supplying cold air in the circulation channel 12 to the refrigeration space 11h through a cold air supply port 15a formed in the wall 10a of the refrigeration space 11h, and a cold air suction unit 20 suctioning cold air from the refrigeration space 11h through a suction port 20a formed in the wall 10b of the refrigeration space 11h; the control unit 30 has the function of controlling the flow rate adjustment unit 15 to form a flow along the wall 10b of the refrigeration space 11h provided with the suction port 20a of the cold air suction unit 20 by means of the cold air supplied from the flow rate adjustment unit 15.
