Food non-freezing fresh-keeping control method, refrigeration equipment and storage medium

Abstract

The invention provides a food non-freezing fresh-keeping control method, refrigeration equipment and a storage medium. The control method comprises the following steps that an instruction acquisitionstep is used for acquiring a fresh-keeping storage instruction; a heating step is used for controlling a compressor to operate at a heating preset temperature Tons so as to heat stored food to the freezing point temperature of the stored food or above; a supercooling introduction step is used for controlling the compressor to operate at an introduction preset temperature Tond so as to reduce the temperature of the stored food to the freezing point temperature of the stored food or below; and a supercooling maintaining step is used for controlling the compressor to operate at a maintaining preset temperature Tonw for a preset time tw so as to maintain the temperature of the stored food at the freezing point temperature of the stored food or below. According to the food non-freezing fresh-keeping control method, when the newly input food is stored, the heating step is firstly carried out, so that the previously stored food in an over-frozen state is effectively prevented from being frozen due to cooling, and the fresh-keeping effect and quality of the food are further improved.

Description

technical field [0001] The invention belongs to the technical field of refrigerator refrigeration, and in particular relates to a control method for keeping food fresh without freezing, refrigeration equipment and a storage medium. Background technique [0002] With the rapid development of air-cooled refrigerators and consumers' strong demands on refrigerator functional partitions, the multi-function of refrigerators has developed rapidly. Generally speaking, there are two main types of food storage temperature in the refrigerator: [0003] 1. Fixed single temperature control, such as precise control of the temperature and humidity of fruits and vegetables in the refrigerator freezer, soft freezing of meat, zero-degree freshness preservation, etc., all use a single fixed temperature to keep the corresponding stored food fresh; [0004] 2. Non-fixed single temperature control, using temperature control of high temperature and low temperature alternate operation, so that the...

Problems solved by technology

[0005] But then comes the problem of food freezing. Under a single temperature condition, such as soft freezing at -3°C, the meat will continue to freeze and become harder and harder.

The control program of high and low temperature alternates, if the low temperature stage is too long, there will be a risk of freezing, especially in the existing technology, which is often based on the design concept that rapid cooling and freezing can maintain the quality of food to the greatest extent. After the food is placed in the storage area, Both require the control system to be able to run the rapid cooling process first, and such a control strategy can have a positive effect on the quality of newly released food, but it will cause them to enter a super-frozen state more easily for previously stored food, making these previously stored foods Food is sharply reduced on fresh-keeping quality, proposes the present invention based on this deficiency in the prior art
