AIR-COOLED REFRIGERATION DEVICE

WIPO Patent Application WO/2023/029516

A1

Provided in the present invention is an air-cooled refrigeration device, aiming to solve the problem of incomplete defrosting of an evaporator of existing air-cooled refrigeration devices during defrosting. The air-cooled refrigeration device comprises a device body, an evaporator, an evaporation fan, a first air throttle and a second air throttle. The device body defines a storage chamber, a refrigeration chamber, an air return duct and an air supply duct. The storage chamber and the refrigeration chamber are respectively in communication with the air return duct. The storage chamber, the refrigeration chamber and the air return duct are respectively in communication with the air supply duct. The evaporator is arranged inside the refrigeration chamber. The evaporation fan is used to convey air from the refrigeration chamber into the air supply duct. The first air throttle is used to block communication between the storage chamber and the air supply duct. The second damper is used to block communication between the air return duct and the air supply duct. The present air-cooled refrigeration device can completely remove frosting on the evaporator, thereby ensuring the refrigeration efficiency of the air-cooled refrigeration device.
