Problems solved by technology

[0004] (1) The uneven temperature drop in the supercooling process causes the supercooling to be released in advance
[0005] (2) The effect of supercooling relief is not good, by increasing the wind speed or air volume
[0006] (3) The depth of supercooling is shallow, and it cannot enter the supercooling state well

Abstract

The invention relates to a refrigeration equipment instantaneous freezing control method and refrigeration equipment. The refrigeration equipment instantaneous freezing control method comprises a staged temperature reducing overcooling process, an overcooling relieving process and a conventional refrigeration preservation process, wherein in the overcooling temperature reducing process, objects tobe cooled are subjected to staged temperature reducing, temperature reducing of each stage is achieved through the mode of implementing cooling control on an instantaneous freezing chamber, each temperature reducing stage of the staged temperature reducing overcooling process is provided with compressor preset accumulation working duration corresponding to the stage; and a compressor is controlled to work periodically stage by stage according to the preset accumulation working duration; and in the overcooling relieving process, the rotating speed of a condenser fan is increased, the rotatingspeed of the compressor is increased, and the overcooling relieving operation is carried out, so that overcooling relief of the storage objects stored in the instantaneous freezing chamber is achieved, then instantaneous-moment freezing (instantaneous freezing for short) of the storage objects is realized, and the frozen storage objects are stored for a long term at the conventional refrigerationpreservation temperature.

Description

technical field [0001] The invention relates to a control method for instant freezing of refrigeration equipment and refrigeration equipment, in particular to a control method capable of realizing instant freezing of food and a refrigerator. Background technique [0002] In order to better maintain the nutrition of frozen food, ordinary freezing, rapid freezing and other freezing methods are usually used for food preservation. However, traditional ordinary freezing has disadvantages such as uneven temperature control in the freezing chamber and staying in the maximum ice crystal formation zone for a long time. ; And although rapid freezing can pass through the maximum ice crystal formation zone fast, the production cost is higher, which is unfavorable for popularization and application on the refrigerator. The supercooling freezing technology can make the fresh-keeping objects form uniform and fine ice crystals after the supercooling process, which can better maintain the fl...
