This type of refrigerator uses a single- The evaporator is used to save material cost. The lowest temperature of the refrigerant is about -25 to -20 °C and exchange heat with the air in the freezer compartment to keep the room temperature at -18 C to achieve the freezing effect. Because the temperature in the refrigerator is too large, the temperature difference between the cold air and the refrigerating chamber is too large. Oh, so a damper must be installed between this air duct to adjust the air duct into the refrigerated wind, even if it is completely closed, to maintain the temperature of the refrigerator compartment around 3. Therefore, the design of the wind and the damper directly affects the freshness preservation effect of the refrigerator and the use efficiency of the electric energy. At present, the technologies disclosed in the current state can be divided into two categories: (1) Most of the analog-controlled models use a temperature-sensing mechanical damper, which uses a temperature-sensing package to fill a refrigerant with a saturation temperature of about 3 art. The refrigerant in the temperature sensing bag expands or condenses due to the change of the refrigerating temperature, and then drives the membrane spring on the mechanical damper link to change the force on the damper connecting rod to achieve the effect of adjusting the air volume of the air duct. This type of control method has the following disadvantages: i. Temperature control accuracy is poor, and it is easily affected by the environment. 11.1276764 iii· Qiao: 'For example, cold air mass attacks cause freezing and freezing of fruits and vegetables. ,: Automatic switch with refrigerator control strategy. (2) The title is Mengzibei, and the valley is suitable for the temperature regulation of the quasi-rotation due to the better heat transfer. The new digital damper adopts temperature feedback, and the motor on the damper link is controlled by the line, and the air volume entering the enthalpy is fully open or fully closed to achieve the purpose of temperature control of the refrigerating compartment. This type of control method has the following disadvantages: i. The mechanism design is complicated. 11, only in the full open or fully closed mode transport #, still # method for proportional air volume adjustment. Therefore, there is a need for a refrigerator damper adjusting device to solve the above problems.
