Refrigeration equipment with deep freezing function and control method of equipment

Abstract

The invention discloses refrigeration equipment with a deep freezing function and a control method of the equipment. The refrigeration equipment comprises at least two chambers including a cold storage chamber and a freezing chamber, and all the chambers of the refrigeration equipment share one refrigeration system, and are provided with air inlet ports and air return ports respectively; air inletducts of all the chambers are internally provided with respective independent air doors and fans respectively, by controlling opening or not of all the air doors, air feeding or not of all the chambers is controlled accordingly, and all the chambers are internally provided with temperature sensors; the refrigeration equipment is further provided with a control device, through the control device,opening and closing of compressors and the air doors are controlled, thus the temperatures of all the chambers are controlled, the freezing chamber is a deep-freezing and quick-freezing area, and theminimum temperature of the freezing chamber is minus 33 DEG C. Compared with the prior art, the refrigeration equipment has the following advantage of being capable of achieving the food deep-freezingand quick-freezing function.

Description

technical field [0001] The invention relates to a refrigeration device, in particular to a refrigeration device with a deep freezing function and a control method thereof. Background technique [0002] The lowest temperature in the freezer compartment of household refrigerators on the market is -24°C, and the general freezing temperature is -18°C. Some refrigerators in the prior art have a quick-freezing function, but there are the following deficiencies: [0003] (1) This functional area cannot meet the storage requirements of food or seafood with a long frozen storage period. [0004] (2) The user buys a large amount of food at one time and needs to freeze the food quickly. The existing freezing technology cannot provide faster cooling and freezing speed. [0005] (3) In some cases, when the quick-freezing function is set on the whole machine, the temperature in the refrigerator room will be lowered and the food in the refrigerator room will be frostbitten.
