Problems solved by technology

[0004] In fact, the working environment of refrigerators is very different, and the load in the box will change at any time. Only two states of the air door switch are used to control the cooling of the compartment, and the air volume supplied by it is not adjustable. Effective adjustment to achieve better cooling conditions
It can be seen from the above that the existing air volume control technology cannot effectively control the cooling capacity of the refrigerator compartment

Embodiment Construction

[0025] In this example, if figure 1 As shown, a method for controlling the air volume of the refrigeration compartment of a refrigerator is applied in an air-cooled refrigerator controlled by an electric damper; the working angle of the electric damper is divided into R stalls; respectively Md 1 ,Md 2 ,...,Md R ;Fan speed is divided into S stalls; 1 ,Fd 2 ,...,Fd S ; In specific implementation, the working angle of the electric damper can be any position between 0°-90°, 0° is the closed state, and 90° is the fully open state; the fan speed can be between 1200r / min-1800r / min Arbitrary speed; the control method is carried out according to the following steps:

[0026] Step 1. When the refrigerator is powered on for the first time, the electric damper of the refrigeration compartment controlled by the damper operates at the maximum working angle and the fan operates at the highest speed;

[0027] Step 2. Determine whether the operation of the air-cooled refrigerator satisfi...

Abstract

The invention discloses an air capacity control method for a refrigerating compartment of a refrigerator and the refrigerator. The air capacity control method is characterized in that the refrigerator is energized for the first time; during the refrigeration of the refrigerating compartment controlled by a throttle, an electric throttle runs at a maximum angle, and a fan runs at the highest rotating speed; when an N-th refrigerating period of the refrigerator is finished, the first N-time startup ratio beta i is calculated; the angle of the electric throttle and the rotating speed working state of the fan during the next refrigeration of the compartment are determined according to the given startup ratio. The advantage of air capacity adjustability of the compartment of the refrigerator is fully utilized, so that the refrigerating quantity of the compartment of the refrigerator is effectively controlled, and the aims of uniformizing the internal temperature of the refrigerator and saving energy are achieved.

Description

technical field [0001] The invention relates to a refrigerator air volume control method and a refrigerator adopting the method, belonging to the field of refrigerator control. Background technique [0002] In recent years, frost-free air-cooled refrigerators have become more and more popular. All air-cooled refrigerators adopt forced convection circulation. The hot air in the box flows into the evaporator through the return air duct, and convects heat exchange with the evaporator. The cold air is forced to blow through the fan. Into the air outlet, through the air duct into the refrigerator compartment. If the refrigerator has two or more rooms, but only one evaporator, the cooling of other rooms except the room where the evaporator is located is controlled by the switch of the electric air door. [0003] At present, the mainstream control method to achieve compartment cooling through the switch state of the electric damper is that when the refrigerator compartment has a c...
