Abstract

The invention discloses a defrosting control method for an air-cooled refrigerator, which relates to the technical field of refrigerators. The defrosting control method of air-cooled refrigerator includes defrosting condition judgment, parameter correction method when exiting defrosting, defrosting execution and exit judgment; defrosting condition judgment method needs to collect relevant time parameters, sensor parameters and damper status: time parameters include compression The accumulative operating time t1 of the refrigerator, the energized operating time t2 of the refrigerator, and the accumulative defrosting time t3 during defrosting; sensor parameters include freezing chamber sensor temperature Td, ambient temperature Hw, and evaporator surface temperature Te. The present invention can effectively save the energy consumption of the air-cooled refrigerator by setting the structural layout of the air-cooled refrigerator and coordinating with the defrosting control method.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, in particular to a defrosting control method for an air-cooled refrigerator. Background technique [0002] The air-cooled refrigerator is also called a frost-free refrigerator. Its working principle is: the high-temperature air from the outside flows through the evaporator installed inside the refrigerator for heat exchange, so that the temperature of the air after the heat exchange is lowered, and the temperature has been lowered after the heat exchange. The cold air is blown into the refrigerator compartment through the air duct, so as to achieve the purpose of cooling. During the above working process, the moisture in the high-temperature air will condense and frost on the surface of the cold evaporator when it encounters the cold evaporator. As it is used for a long time, it will easily lead to poor cooling effect and shorten the service life of the refrigerator. [0003] In the prior ...
