The refrigerating system of direct cooling single-system refrigerators belongs to the category of dual temperature and single-control refrigerating system. The heat conducting area of the corresponding evaporator determines the refrigerating capacity of its refrigerator or freezer compartment. After being throttled by the capillary, the low-pressure refrigerant flows through the refrigerator compartment evaporator first and then the freezer compartment evaporator, thus, completing the whole process of refrigeration.
