DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0036] like Figure 1 and Figure 2 As shown, the present invention provides a refrigeration system, including a refrigeration device and a refrigerant filled in the refrigeration device to provide cooling to a space to be refrigerated, wherein the refrigerant is made of reusable ammonium nitrate.

[0037] The refrigeration principle used in the present invention is that ammonium nitrate absorbs a large amount of heat when dissolved in water.

[0038] The refrigeration system provided by the present invention realizes the refrigeration cycle of ammonium nitrate, and uses ammonium nitrate dissolved in water to cool the cold storage room. The ammonium nitrate dissolved in water will absorb a large amount of heat, so that the ambient temperature can be reduced to about 0°C; and the decomposition temperature of ammonium nitrate is as high as 300°C, and it is not easy to decompose under normal use; the refrigeration system using ammonium nitrate dissolved in water can not only realize refrigeration, but also its waste is a kind of high-quality fertilizer, which is normally in solid or liquid state, easy to recycle, and will not cause environmental pollution.

[0039] As an optional embodiment of the present invention, Figure 2 As shown, the refrigeration device includes a shell 1 and a refrigeration fin 2. The refrigeration fin 2 is placed in the shell 1. Water is stored in the shell 1 on one side or both sides of the refrigeration fin 2. The refrigeration device also includes a driving component that is transmission-connected to the refrigeration fin 2 to pull the refrigeration fin 2 to move back and forth. When the driving component pulls the refrigeration fin 2 to move, the water can mix with the ammonium nitrate stored in the refrigeration fin 2.

[0040] Specifically, when there is water on both sides of the refrigeration fin 2, there is no need for a completely sealed contact connection between the bottom of the refrigeration fin 2 and the bottom of the shell 1, and some water can be allowed to enter from one side to the other side through the bottom gap.

[0041] When there is water on one side of the refrigeration fin 2 , the bottom of the refrigeration fin 2 and the bottom of the shell 1 should be in watertight contact connection.

[0042] Further, such as Figure 5 As shown, the refrigeration plate 2 has a containing cavity 3 inside, which stores solid ammonium nitrate; a water inlet hole 4 is provided on the upper side wall of the refrigeration plate 2, and the water inlet hole 4 is connected to the containing cavity 3 through a water channel 5.

[0043] By arranging the accommodating cavity 3 inside the refrigeration plate 2 and arranging the water inlet hole 4 on the upper part of the refrigeration plate 2, the ammonium nitrate is not easy to overflow.

[0044] As shown Figures 2 - 5 in, further, the number of water inlet holes 4 is multiple, and they are evenly arranged along the width direction of the cooling fin 2. The width direction of the cooling fin 2 referred to here means the horizontal direction as shown Figure 2 in, or, as shown Figure 3 in, the direction extending from the left side to the right side of the cooling fin is the width direction.

[0045] As shown Figure 6 in, the driving assembly includes a rack and a gear. There are two racks, which are respectively located on both sides of the gear. The racks on both sides are respectively connected to the two cooling fins 2. The gear is connected to the motor. When the gear rotates, the moving directions of the racks on both sides are exactly opposite to drive the two cooling fins 2 to move in opposite directions respectively.

[0046] As shown Figure 4 and 5 in, the water channel 5 is arranged along the height direction of the cooling fin 2, the bottom end is communicated with the accommodating cavity 3, and the top end extends to the top surface of the cooling fin 2.

[0047] As an optional implementation manner of the present invention, as shown Figure 5 in, the accommodating cavity 3 is located at the middle position in the height direction of the cooling fin 2. The height direction referred to here means the direction from top to bottom as shown Figure 5 in, and the middle position in the height direction of the cooling fin refers to the position of 1 / 3 - 2 / 3 of the total height of the cooling fin.

[0048] As shown Figure 4 in, there are two accommodating cavities 3 in the housing 1, which are arranged side by side along the width direction; the cooling fins 2 are arranged in each accommodating cavity 3. Through this structural arrangement, ammonium nitrate in one cooling fin 2 can be used to cool the refrigerating chamber each time, while the other cooling fin 2 is used for the recondensation of ammonium nitrate, and they can be used alternately without waiting, ensuring the continuous cooling state of the refrigerating chamber all the time.

[0049] As an optional implementation manner of the present invention, as shown Figure 3 in, the refrigeration device further includes a liquid supplementing assembly connected to the housing 1 for water supplement.

[0050] Further, the liquid supplementing assembly includes a water storage box 6. The housing 1 is inserted into the water storage box 6, and a water replenishing port 7 is opened on the housing 1. The water in the water storage box 6 is supplemented into the housing 1 through the water replenishing port 7.

[0051] Furthermore, the water replenishing port 7 is opened on the side of the housing 1 facing the water inlet hole 4.

[0052] As an optional implementation manner of the present invention, the water replenishing port 7 is opened at the bottom of the side wall of the housing 1.

[0053] As an alternative embodiment of the present invention, the top of the water storage box 6 is located below the bottom of the accommodation cavity 3.

[0054] As an alternative embodiment of the present invention, the bottom of the housing 1 extends vertically downward to form a support portion 8, and a bottom groove 9 is formed between the two support portions 8. The bottom groove 9 is in communication with the inner cavity of the water storage box 6.

[0055] Furthermore, the refrigeration system further includes a condensation component disposed at the rear side of the refrigeration device to cool and solidify ammonium nitrate.

[0056] The condensation component includes one or two of a condenser 10 and a heater.

[0057] A refrigerator provided by the present invention includes a refrigerator inner liner 11 and a refrigeration system disposed at the rear side of the refrigerator inner liner 11.

[0058] As Figure 1 shown, a refrigerator provided by the present invention includes a box body 12, a freezer, a rear back plate 13 and a refrigerator compartment; it further includes an air-cooled refrigeration system connected to the freezer to provide cold air to the freezer.

[0059] The present invention provides a dual-system refrigerator. On the basis of the original air-cooled refrigerator, an ammonium nitrate circulation refrigeration device is added to refrigerate the refrigerator compartment. Using ammonium nitrate as a refrigerant can not only meet the temperature requirements of the refrigerator compartment, but also cause no pollution to the environment. The refrigeration of the freezer of this dual-system refrigerator is the same as that of a traditional refrigerator, and the refrigerator compartment uses the method of ammonium nitrate dissolved in water for refrigeration.

[0060] This dual-system refrigerator mainly includes an ammonium nitrate refrigeration device, a rear back plate 13 attached to the condenser 10, and a box body 12, as Figure 1 . As Figure 2 shown, it is an exploded view of the ammonium nitrate refrigeration device, which is composed of a housing 1, a refrigeration sheet 2, and a water storage box 6. The refrigeration sheet 2 is provided with an accommodation cavity 3 for storing ammonium nitrate. Above the accommodation cavity 3, there are a water inlet hole 4 and a water channel 5 for introducing water into the accommodation cavity 3 and preventing the ammonium nitrate solution from overflowing easily, as Figure 3 . At the same time, a water replenishing port 7 is opened on the housing 1 to ensure a certain amount of water between the refrigeration sheet 2 and the inner wall of the housing 1, as Figure 4 . When the refrigeration sheet 2 moves towards the inner wall of the housing 1, the water level of this part will rise. When it rises to the height of the water inlet hole 4 of the refrigeration sheet 2, the water will flow into the accommodation cavity 3 filled with ammonium nitrate solid, dissolving the ammonium nitrate to achieve the refrigeration effect. As Figure 5As shown, it is shown that the refrigeration device is provided with two Peltier elements 2. When the ammonium nitrate in the Peltier element 2 on the side of the refrigerated compartment is completely dissolved, the Peltier element 2 will be pulled back to the side of the rear panel 13, and the condenser 10 and the heater will heat and evaporate the ammonium nitrate solution in the Peltier element 2, finally forming ammonium nitrate solid. And the Peltier element 2 on the other side will be pushed towards the side of the refrigerated compartment for refrigeration to ensure continuous refrigeration effect. As Figure 6 shown, it is a rack and pinion structure. The gear is a driving gear, and there is a square structure on the rack for connecting the Peltier element 2. When the gear rotates, the racks on both sides will move in opposite directions, thereby driving the two Peltier elements 2 to move in opposite directions respectively.
