The implementation principle of the above embodiment is as follows:

after the flow regulating switch 22 on the flow regulating valve 2 is started to be opened at different degrees, the heat medium pump 33 presses the cooling and heating medium in the high-temperature tank 3 into the high-temperature pipe 31, the high-temperature pipe 31 in the high-temperature pipe 31 flows to the corresponding valve port 21, the normal-temperature pump 43 presses the cooling and heating medium in the normal-temperature tank 4 into the normal-temperature pipe 41, the cooling and heating medium in the normal-temperature pipe 41 flows to the corresponding valve port 21, the cooling and heating medium in the low-temperature tank 5 is pressed into the low-temperature pipe 51 by the cooling medium pump 53, and the cooling and heating medium in the low-temperature pipe 51 flows to the corresponding valve port 21, so that the;

the cooling medium in the reaction kettle 1 flows out from the water outlet pipe 12, and the cooling medium in the water outlet pipe 12 flows into the corresponding high-temperature tank 3, normal-temperature tank 4 and low-temperature tank 5 through the high-temperature return pipe 32, normal-temperature return pipe 42 and low-temperature return pipe 52 in sequence;

the heating mechanism 6 heats the cooling and heating medium in the high-temperature tank 3, and the cooling mechanism 8 exchanges heat with the cooling and heating medium in the normal-temperature tank 4 to keep the cooling and heating medium at normal temperature, so that the temperature of the cooling and heating medium in the high-temperature tank 3 and the normal-temperature tank 4 is kept stable;

when valley electricity is used and the refrigerant liquid in the low-temperature tank 5 needs to be cooled to a temperature of-50 ℃ to below 5 ℃, the refrigerating unit 712 cools the fluid in the ice storage device 713, and when peak electricity is used, the refrigerating unit 712 firstly uses the low-temperature fluid in the ice storage device 713 and discharges the low-temperature fluid into the refrigerating pipe 55 so that the refrigerating pipe 55 cools the cold and heat medium in the low-temperature tank 5;

when valley electricity is used and the refrigerant liquid in the low-temperature tank 5 needs to be cooled to 5-10 ℃, the water chilling unit 722 cools the fluid in the water cold storage device 723, and when peak electricity is used, the water chilling unit 722 firstly uses the low-temperature fluid in the water cold storage device 723 and discharges the low-temperature fluid into the low-temperature pipe 51, so that the low-temperature pipe 51 cools the cold and heat medium in the low-temperature tank 5;

by storing the electric power at the valley power into the ice thermal storage device 713 or the water thermal storage device 723, the power supply pressure at the peak power is relieved, and the valley power charge is relatively low, which contributes to cost reduction.
