[0028] Cold storage technology is currently widely used in the air conditioning industry. During periods of low grid power consumption, electric refrigeration units convert water into ice or low-temperature cold water, storing it in a cold storage device. During peak power consumption, the ice is melted and the cold water is released to provide a cooling source for air conditioning. This highly efficient energy-saving technology achieves peak-to-valley power shifting. Cold storage systems for air conditioning primarily include ice and water storage systems.

[0029] Existing cold storage equipment only has the function of making ice and storing cold, and can only provide ice water or low-temperature cold water, but cannot provide cold air at the same time, and its functions are relatively simple; moreover, the heat exchange in the existing cold storage water tank mostly adopts tubular heat exchangers, with circular or oval pipes built into the water tank, which requires a large amount of refrigerant and has low heat exchange efficiency.

[0030] Reference Figures 1 to 4 The present application provides a multifunctional cold storage device, including a first box body 100, a second box body 200 and a heat exchange plate 300. An air outlet, a return air outlet, an external circulation water outlet 101 and an external circulation return water outlet 102 are installed on the top of the first box body 100. An air outlet valve 104 is installed at the air outlet, and a return air valve 105 is installed at the return air outlet. The height of the second box body 200 is lower than that of the first box body 100. The second box body 200 is connected to the first box body 100. The heat exchange plate 300 is installed inside the first box body 100. The heat exchange plate 300 is a plate-shaped structure. A grid-shaped flow channel 301 is provided inside the heat exchange plate 300. The head end of the flow channel 301 forms a refrigerant inlet on the heat exchange plate 300, and the end of the flow channel 301 forms a refrigerant outlet on the heat exchange plate 300.

[0031] During the off-peak period of electricity consumption, the water in the second box 200 is pumped into the first box 100, and the refrigeration device supplies the refrigerant to the heat exchange plate 300, which cools and stores the water in the first box 100. During the peak period of electricity consumption, when the user needs cold air, the air outlet valve 104 on the top of the first box 100 works to blow the cold air in the first box 100 to the user, and the heated air continues to be blown into the first box 100 through the return air valve 105. This cycle continues. When the user needs cold water, the external circulation water outlet 10 1 and the external circulation return water port 102 are both connected to the user end through pipes. The cold water in the first box 100 flows out from the external circulation water outlet 101, releases the cold energy through the user end, and then flows into the first box 100 from the external circulation return water port 102, and so on. Therefore, this cold storage device has the multifunctional purpose of supplying cold air and supplying cold water, realizing multiple functions of one machine. In addition, the heat exchange plate 300 of the present application is provided with a grid-distributed flow channel 301, so the contact area between the heat exchange plate 300 and the water in the first box 100 is larger, and the cooling efficiency is higher. Moreover, during the use of the present application, cold energy is stored during the off-peak period of electricity consumption and cold energy is released during the peak period of electricity consumption, which can effectively save cooling and electricity costs.

[0032] In some embodiments, the first tank 100 and the second tank 200 are two upper and lower tanks separated by a horizontal partition 103 in the same cold storage tank. The lower second tank 200 is specifically used to store water. When cold storage is needed, the water in the second tank 200 is pumped into the first tank 100. After cooling is completed, the water in the first tank 100 can be released into the second tank 200, reducing the weight of the first tank 100.

[0033] Of course, the first box body 100 and the second box body 200 can also be set as two independent boxes. The first box body 100 and the second box body 200 can be connected up and down, or can be spaced apart and connected through a hose.

[0034] In some embodiments, the heat exchange plate 300 is mounted inside the first housing 100 via a fixing bracket 700, which is detachably connected to the first housing 100.

[0037] In order to further ensure the firmness of the heat exchange plate 300 in the first box body 100, in some embodiments, a connection area 310 is provided around the flow channel 301 of the heat exchange plate 300, and a through hole 311 is opened in the connection area 310. A connecting rod 800 is passed through the through hole 311, and both ends of the connecting rod 800 are connected to the inside of the first box body 100.

[0038] In order to facilitate the flow of water in the first tank 100 into the second tank 200 , in some embodiments, the bottom of the first tank 100 is connected to the top of the second tank 200 through a first connecting pipe 400 , and a valve 401 is installed on the first connecting pipe 400 .

One end of the first connecting pipe 400 is connected to the first box body 100, and the other end is connected to the second box body 200. The valve 401 installed on the first connecting pipe 400 is an electric valve. When the water in the first box body 100 needs to be released, the electric valve is controlled to open, thereby releasing the water in the first box body 100 into the second box body 200.

[0040] In order to facilitate the delivery of water from the second tank 200 to the first tank 100 , in some embodiments, the top of the first tank 100 is connected to the bottom of the second tank 200 via a second connecting pipe 500 , on which a delivery pump 501 is installed.

[0041] Specifically, the lower end of the second connecting pipe 500 is connected to the lower part of one side of the second box body 200, and the upper end of the second connecting pipe 500 is connected to the upper part of one side of the first box body 100. When water is needed in the first box body 100, the delivery pump 501 on the second connecting pipe 500 pumps the water in the second box body 200 to the first box body 100.

[0042] In some embodiments, the top of the first box body 100 is connected to the top of the second box body 200 via a balance pipe 600. This ensures that the air pressure between the first box body 100 and the second box body 200 is balanced.

[0047] Specifically, the water supply port 107 is opened on the side of the top of the first box body 100.

[0048] In some embodiments, an overflow port 110 is installed on the first housing 100. Specifically, the water supply port 107 is opened on the side of the top of the first housing 100. Avoid the liquid level in the first housing 100 being too close to the air outlet valve 104 and the air return valve 105.
