After closing the storage door 150, the control unit 700 is operated to start the above multiple static induction devices 610, so that an electrostatic field is generated in the refrigerator main body 100. At this time, the supply unit is controlled by the control unit 700. The heating equipment 300 starts to supply heat, and controls the cooling equipment 200, heating equipment 300, and air circulation equipment 400. According to the temperature data and humidity data fed back by the temperature sensor 20 and the humidity sensor 540, the settings in the refrigerator body 100 are set. The temperature is adjusted and controlled at 25 ° C, and the frozen product placed on the material storage unit is defrosted for 8 hours. After that, the set temperature in the freezer body 100 is adjusted and controlled at 15 ° C, and the frozen product placed on the material storage unit is defrosted.

Through the above three-stage electrostatic thawing method, the thawing effect can be achieved with high efficiency and high quality. As shown in Figure 10, after the above defrosting step is completed, the fresh-keeping step of the refrigerator body 100 can also be started. Specifically, the control unit 700 can be used to control the refrigeration equipment 200, the heating equipment 300, and the air circulation equipment 400. The temperature data and humidity data fed back by the tester 20 and the humidity sensor 540 adjust and control the set temperature in the main body of the cold storage 100 to 2 ° C, and fresh-keeping the frozen products placed on the material storage unit.

As shown in FIG. 11, when using the electrostatic cold storage system of the present invention to perform freezing operations, the following steps can be performed: Arrange 10 metal racks carrying fresh products within 100 of the cold storage body, and arrange multiple frames 10 They are electrically connected to the output terminals of a plurality of electrostatic inducers 610 respectively. After closing the storage door 150, the control unit 700 is operated to start the above-mentioned multiple electrostatic inducers 610, so that an electrostatic field is generated in the refrigerator main body 100. At this time, the control unit 700 controls the refrigeration. Equipment 200 starts cooling, and controls refrigeration equipment 200, heating equipment 300, and air circulation equipment 400. Based on the temperature data and humidity data of temperature sensor 20 and humidity sensor 540, adjust the set temperature in the main body of the refrigerator 100. And control it at -10 ° C, freeze the fresh product placed on the material placement unit for 4 hours; then adjust and control the set temperature in the freezer body 100 at -15 ° C, and place the fresh product placed on the material placement unit Fresh food is frozen for 4 hours; then set the temperature in the freezer body to 100 The temperature is adjusted and controlled at -25 ° C. The fresh products placed on the material storage unit are frozen for 4 hours. Through the above three steps, the fresh products with an initial temperature of 4-7 ° C are frozen to a center temperature of -18 ° C ~ -25 ° C. The above three-stage electrostatic freezing method can achieve a high-efficiency and high-quality freezing effect.

The above-mentioned method for adjusting and controlling the temperature in the main body of the refrigerator 100 is mainly to use the control unit 700 to control the refrigeration equipment 200, the heating equipment 300, and the air circulation equipment 400. When the temperature in the refrigerator main body 100 detected by the temperature sensor 20 is greater than or equal to the setting, When the temperature is turned on, the cooling equipment 200 is turned on to cool the inside of the refrigerator body 100 so that the temperature in the refrigerator body 100 is controlled to a set temperature; when the temperature in the refrigerator body 100 detected by the temperature sensor 20 is less than or equal to the set temperature, Turn on the heating equipment 300 to increase the temperature of the interior of the refrigerator body 100 so that the temperature in the refrigerator body 100 is controlled to the set temperature.

Since maintaining a certain humidity can effectively accelerate the freezing or thawing operation in an electrostatic environment, and can improve the freshness preservation effect during the freezing or thawing operation, it is best to set the humidity in the refrigerator body during the above freezing operation or thawing operation. It is controlled within a certain range, and the humidity control in the main body of the cold storage is realized by the above-mentioned humidification system 500. When the humidity in the refrigerator body 100 detected by the humidity sensor 540 is less than or equal to the set humidity, the control unit 700 can send a signal to control the humidity control device 530 to start the humidification system 500, and perform humidification operation on the interior of the refrigerator body 100. Specifically, the nozzle 520 is used to spray water mist or water droplets on the processed fresh or frozen products. The humidity control device 530 also includes an adjustable humidification timer, so as to control the time for spraying water mist or water droplets during humidification. For example, when the humidification program is started, a spray time and a pause time can be set. For example, every 6 seconds of spraying, pause for 1 minute. This is because during the humidification process, the surface of fresh or frozen products first comes into contact with water, so the humidity of the surface changes faster than the body of the cold storage detected by the humidity sensor. The humidity change rate is much faster. Therefore, in order to avoid excessive humidification of fresh or frozen products, it is necessary to gradually spray during the humidification process, that is, to pause during the spraying process, so that the humidity in the cold storage body 100 The degree of humidification of the frozen product is as close as possible, so that the humidity sensor 540 can accurately convey the change in humidity, so as to avoid excessive spray humidification of fresh or frozen products. The adjustment range of the injection time is 1 to 30 seconds, and the adjustment range of the pause time is 1 to 6 minutes. In the embodiment of the present invention, during the freezing or thawing operation, the humidity in the refrigerator body 100 is preferably controlled between 80% and 90%, and the humidity in the refrigerator body 100 is more preferably controlled at 85%.

For the cold storage body 100 provided with the ventilation device 800, the opening or closing of the ventilation device 800 can also be controlled by the control unit 700, so as to introduce outside air into the inside of the cold storage body 100, which is used to cooperate with the above-mentioned refrigeration equipment 200 of the cold storage body 100. 300 thermal equipment, 400 air circulation equipment, adjust the temperature inside the freezer body 100. When the temperature inside the freezer body 100 detected by the temperature sensor 20 is equal to or higher than the set temperature, the low-temperature air can be introduced by turning on the ventilation device 800. To assist in cooling the inside of the cold storage body 100; when the temperature in the cold storage body 100 detected by the temperature sensor 20 is less than or equal to the set temperature, the ventilation equipment can be opened to introduce high-temperature air from the outside to assist the inside of the cold storage body 100 Warm up. Therefore, on the one hand, it can assist in controlling the temperature in the refrigerator body 100, on the other hand, it can save the power consumption of the refrigeration equipment or heating equipment, and on the other hand, it can also assist in adjusting the humidity in the refrigerator body 100.

For the above-mentioned cold storage group, the defrosting operation is performed in a cold storage body 100 provided with a ventilation device 800.
