Abstract

The invention discloses refrigeration equipment, relates to the technical field of refrigeration, and aims to reduce the temperature fluctuation amplitude of a refrigeration chamber and reduce the defrosting energy consumption in the process of defrosting an evaporator by utilizing a defrosting device. The refrigeration equipment comprises the refrigeration chamber and a refrigeration assembly; the refrigeration assembly comprises an evaporator assembly and an air duct assembly; the evaporator assembly comprises an evaporator bin, an evaporator located in the evaporator bin and the defrostingdevice; the air duct assembly comprises a draught fan and an air cavity used for communicating the evaporator bin with the refrigeration chamber, an air inlet of the draught fan is located in an air inlet of the air cavity, and an air outlet of the draught fan is in communication with the air cavity; and the air duct assembly further comprises a controllable shielding unit arranged at the air inlet of the draught fan, and the controllable shielding unit opens or closes the air inlet of the draught fan in a controlled state. The refrigeration equipment is used for food preservation.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigeration device. Background technique [0002] Air-cooled refrigerator is a kind of refrigerator that uses air for cooling. Its refrigeration principle is to use the built-in evaporator to directly cool the air flowing through the built-in evaporator, so that the air temperature is lowered, and the obtained cold air is blown into the inside of the refrigerator to achieve the purpose of refrigeration. Purpose. [0003] After the built-in evaporator of the existing air-cooled refrigerator is refrigerated and frosted, the heating wire is generally used to heat the evaporator to defrost the evaporator, so that the user does not need to defrost, which brings great convenience to the user. However, the hot air produced by heating the evaporator with the heating wire will directly enter the freezer compartment, causing temperature fluctuations in the freezer compartment, r...
