Refrigerator

Abstract

The application relates to the technical field of refrigeration equipment, and provides a refrigeration box. The refrigeration box comprises a box body, a ventilation system and a switch assembly; the box body has a storage space inside; the ventilation system comprises a first air duct and a second air duct which are communicated with each other, the first air duct and the second air duct are independently communicated with the storage space, a refrigeration device is arranged in the first air duct, and a cold storage device is arranged in the second air duct; the switch assembly is arranged in the first air duct and the second air duct to control the flow path of air among the first air duct, the second air duct and the storage space; when the air flows between the first air duct and the storage space, the refrigeration device refrigerates the storage space; when the air flows between the first air duct and the second air duct, the cold storage device absorbs the cold energy of the air cooled by the refrigeration device to store cold; when the air flows between the second air duct and the storage space, the cold storage device refrigerates the storage space. When the refrigeration device is powered off, the cold storage device releases the stored cold energy, so that the temperature rise in the refrigeration box is avoided to prevent the damage of goods.
