Background

The air-cooled refrigerator sends cold air into each compartment through a fan and an air duct, and the temperature in the compartment is reduced by forced air convection.

For air-cooled refrigerator products, according to the existing experimental tests: when the ambient temperature is 30 ℃, the refrigerator is opened for 10 seconds, the temperature in the refrigerator rises to 5-6 ℃, and if the refrigerator is opened for 1-2 minutes, the temperature in the refrigerator reaches the external ambient temperature. After the refrigerating door is closed, if the room temperature is returned to the set temperature again, the compressor is continuously operated for at least more than 20 minutes. The refrigerator has a large amount of cold energy losses in the door opening stage, and the refrigerator door opening stage not only can bring huge temperature fluctuation to the compartment and influence the fresh-keeping effect of food materials, but also can correspondingly increase the power consumption of the refrigerator.
