[0032] Example

[0033] Ice trough technology is a set of technology that takes advantage of the low-price electricity at night to make ice and store cold energy, and then melts it into water during the daytime peak electricity consumption to provide cooling together with the refrigeration unit. When the air-conditioning load is at its peak during the day, the stored ice cold energy is released to meet the peak air-conditioning load needs.

[0034] During the design process, the inventors found that the traditional ice storage tank places the heat exchange coil in the ice storage tank, which is full of heat exchange coils and difficult to maintain. After multiple ice storage / ice release cycles, residual ice will be generated, which cannot be completely melted and is difficult to remove. At the same time, the ice storage tank usually contains ethylene glycol aqueous solution, and the grass interface indirectly exchanges heat with the user's chilled water pipeline through the heat exchange coil, which is costly.

The heat exchanger 200 is located above the water source, and there is a certain distance between the heat exchanger 200 and the highest position of the water source, so that ice flakes of a certain thickness formed during the ice-making process can easily fall off, and the heat exchange efficiency is high.

[0037] In the above implementation process, the heat exchanger 200 is arranged in the accommodating cavity of the unit case 100, and the heat exchanger 200 is connected to the refrigerant system pipeline 600, so that the refrigerant enters the heat exchanger 200 through the refrigerant system pipeline 600, and the circulating water pump 301 is connected to the water pipe structure. When ice making is needed, the refrigerant enters the heat exchanger 200 to absorb heat, absorbs heat and releases cold in the heat exchanger 200, and the circulating water pump 301 works. The water source enters the water pipe structure, is sprayed out by the water pipe structure, and exchanges heat with the heat exchanger 200 to form ice flakes, reaching a certain thickness; when the ice flakes reach a certain thickness and need to be thawed, the refrigerant enters the heat exchanger 200 to release heat, absorbs cold and releases heat in the heat exchanger 200, and the ice flakes absorb heat and break away from contact with the heat exchanger 200, and fall into the water source in the unit case 100 under the scouring of gravity and the water source and break, and this reciprocating cycle is carried out, which can achieve the purpose of ice storage, solve the problem of ice removal difficulty, and improve heat exchange efficiency.

[0038] like Figure 1-Figure 3 As shown, the water pipe structure includes a spray water pipe 302 and a circulating water pipe 303 , the spray water pipe 302 (including but not limited to a spray water pipe) is connected to the circulating water pipe 303 , and the spray water pipe 302 is arranged above the heat exchanger 200 for spraying the heat exchanger 200 .

[0039] In the above implementation process, the spray water pipe 302 is connected to the circulating water pipe 303, the circulating water pipe 303 is connected to the circulating water pump 301, and is directly connected to the unit box 100, so that when the circulating water pump 301 is working, it can provide water for the spray water pipe 302 and spray the heat exchanger 200, without the need for indirect heat exchange through the heat exchanger 200, thereby reducing costs.

[0040] like Figure 1-Figure 5 As shown, the ice storage tank unit also includes an external water inlet, which is connected to the water pipe structure to provide the water source to the accommodating chamber, wherein the external water inlet is used to connect to the user's chilled water pipeline to provide a cold source to the user. The water source is provided to the water pipe structure through the external water inlet, and the water pipe structure is sprayed to the accommodating chamber of the unit box 100, so that a circulation loop can be formed to provide a cold source to the user, without the need for indirect heat exchange through the heat exchanger 200, thereby reducing costs and improving efficiency.

[0041] In some embodiments, the external water inlet includes a chilled water inlet 400 and a chilled water outlet 500, the chilled water inlet 400 is connected to the circulating water pipe 303 between the spray water pipe 302 and the circulating water pump 301, and the chilled water outlet 500 is connected to the circulating water pipe 303 and is located at the bottom of the unit box 100.

[0042] In some embodiments, the refrigerant system pipeline 600 is located on one side of the unit case 100, and the circulation component 300 is located on the other side of the unit case 100. It can achieve reasonable use of space, and the unit case 100 is mass-produced and configured as a set, which improves product quality, shortens on-site construction period, and has the benefits of improving quality, reducing costs and increasing efficiency.

[0043] In some embodiments, the refrigerant system pipeline 600 includes a first refrigerant pipeline 601 and a second refrigerant pipeline 602 , and the first refrigerant pipeline 601 and the second refrigerant pipeline 602 are respectively connected to the heat exchanger 200 .

[0044] In the above-mentioned implementation process, the first refrigerant pipeline 601 and the second refrigerant pipeline 602 are respectively connected to the heat exchanger 200. When ice making is required, one of the first refrigerant pipeline 601 and the second refrigerant pipeline 602 can provide refrigerant to the heat exchanger 200, and enter the heat exchanger 200 to absorb heat and release heat; when defrosting is required, the other of the first refrigerant pipeline 601 and the second refrigerant pipeline 602 can provide refrigerant to the heat exchanger 200, and enter the heat exchanger 200 to release heat.

[0045] In some embodiments, a maintenance port 700 is disposed on one side of the unit case 100. The accommodating cavity of the unit case 100 can be entered through the maintenance port 700, which facilitates maintenance and reduces maintenance costs.

[0047] The working principle of the present application is as follows: the heat exchanger 200 is installed on the upper part of the unit housing 100 at a certain height from the water surface; the heat exchanger 200 is connected to the first refrigerant pipeline 601 and the second refrigerant pipeline 602; the spray water pipe 302 is arranged on the upper part of the heat exchanger 200; when ice making is required, the refrigerant of the ice making unit enters the heat exchanger 200 through the second refrigerant pipeline 602 to absorb heat; after absorbing heat and cooling in the heat exchanger 200, it returns to the ice making unit through the first refrigerant pipeline 601 and then continues to circulate; the water in the unit housing 100 is transported to the spray water pipe 302 through the circulating water pump 301, and then After the spray water pipe 302 sprays water, a water curtain is formed on the surface of the heat exchanger 200. The water curtain releases heat in the heat exchanger 200 to form ice flakes, reaching a certain thickness. When the ice flakes reach a certain thickness and need to be thawed, the refrigerant of the ice-making unit enters the heat exchanger 200 through the first refrigerant pipeline 601 to release heat. After absorbing cold and releasing heat in the heat exchanger 200, it returns to the ice-making unit through the second refrigerant pipeline 602 and continues to circulate. The ice flakes absorb heat and break away from the heat exchanger 200. Due to gravity and the flushing of the spray water pipe 302, they fall into the water of the unit box 100 and break into pieces. The above ice making and ice thawing are circulated through system control to achieve the purpose of ice storage.
