Supercooling control method of refrigerating equipment

Abstract

The invention provides a supercooling control method of refrigerating equipment. The supercooling control method comprises the steps that 1, after a supercooling mode is started, a compressor and a first air feeder operate intermittently; 2, when the temperature detected by a temperature sensor is lower than a first set temperature value T1, the compressor and the first air feeder operate continuously; 3, when the temperature detected by the temperature sensor is lower than a second set temperature value T2, the compressor and the first air feeder operate intermittently, and a second air feeder operates continuously; and 4, when the temperature detected by the temperature sensor is lower than a third set temperature value T3, the refrigerating equipment operates according to a conventional refrigerating mode, specifically, T1>T2>T3. Food is frozen efficiently through supercooling so that the supercooling effect can be improved.

Description

technical field [0001] The present invention relates to a refrigerating device for cooling and preserving food etc. in a storage room, in particular to a supercooling control method for a refrigerating device having the function of supercooling and freezing the food etc. in a freezing room. Background technique [0002] So far, the freezing method of freezing food through a supercooled state during freezing in the freezer has been used. When this method is used, because the ice crystals are small, it is not easy to damage the cells of the food, so the effect of reducing blood loss can be obtained. Chinese Patent No. 2016100332561 discloses a refrigeration device with the above-mentioned supercooling function. By using a loading plate with through holes to place items that need to be overcooled, the cold air output from the air duct at the top of the loading plate passes through the through holes from the loading Items are refrigerated on both the upper and lower portions of ...

Problems solved by technology

However, in the actual use process, it is found that the amount of cold air entering the bottom from the through hole of the mounting plate is relatively small, and the effect of supercooling is still not well achieved.

In addition, in the actual use process, it is found that there is a large difference between the temperature value detected by the temperature sensor and the actual temperature value of the item on the loading plate, and it is impossible to accurately control the supercooling temperature according to the temperature of the frozen item. Very good supercooling effect
