[0001] The utility model relates to the technical field of carbon dioxide refrigeration devices, in particular to a supercritical carbon dioxide refrigeration device for artificial ice rinks. Background Art

[0002] A carbon dioxide refrigeration device is a refrigeration system that uses carbon dioxide as a refrigerant. Carbon dioxide is an environmentally friendly substance that is colorless, odorless, and non-toxic. From a thermodynamic performance perspective, carbon dioxide has the characteristics of high density and low viscosity, small flow losses, and good heat transfer effects. In addition, carbon dioxide has excellent environmental performance, is low in cost and easy to obtain, has good stability, and is conducive to reducing the size of the device.

[0003] In artificial ice rinks, carbon dioxide refrigeration devices are generally used to produce cold air. When the carbon dioxide refrigeration device is in operation, carbon dioxide is required as a refrigerant, and the carbon dioxide refrigerant is generally stored inside a carbon dioxide storage tank. When the carbon dioxide refrigeration device is in operation, its compressor will continuously extract the carbon dioxide refrigerant from the carbon dioxide storage tank, and then with the cooperation of other mechanisms and equipment, it will eventually produce cold air. Although the currently existing carbon dioxide refrigeration devices are more efficient in producing cold air.

[0004] However, since the carbon dioxide refrigerant is consumed quickly and needs to be replenished regularly, the carbon dioxide storage tanks of the existing carbon dioxide refrigeration devices are all installed inside the device and are installed using multiple fixing bolts, which makes it inconvenient to disassemble and assemble, making it difficult to replenish the carbon dioxide refrigerant and not conducive to use. Therefore, a supercritical carbon dioxide refrigeration device for artificial ice rinks is proposed to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] See also Figure 1-4 In this embodiment, a supercritical carbon dioxide refrigeration device for an artificial ice rink includes a carbon dioxide refrigeration device body 1 and a carbon dioxide storage tank 2. A disassembly mechanism is provided on the outside of the carbon dioxide refrigeration device body 1;

[0025] The disassembly and assembly mechanism includes a mounting cylinder 3 fixedly mounted on the right side of the carbon dioxide refrigeration device body 1, a magnetic suction sleeve 4 is fixedly connected to the inner side of the mounting cylinder 3, an annular handle 5 is fixedly connected to the outer surface of the carbon dioxide storage tank 2, a plastic telescopic tube 6 is fixedly connected to the top end of the pipe of the carbon dioxide refrigeration device body 1, a mounting cover 7 is fixedly connected to the front end of the plastic telescopic tube 6, a sealing gasket 8 is bonded to the inner side of the mounting cover 7, a mounting seat 9 is fixedly connected to the top end of the pipe of the carbon dioxide storage tank 2, a clamping ring 10 is fixedly connected around the mounting cover 7, a sleeve block 11 is fixedly connected around the mounting seat 9, and through holes 12 are provided on the outer surfaces of the mounting cover 7 and the mounting seat 9. When it is necessary to replenish the carbon dioxide refrigerant, the staff only needs to release the clamping ring 10 and the sleeve block 11, and then pull the plastic telescopic tube 6 upwards to pull the mounting cover 7 off from the top of the mounting seat 9, so as to release the pipe connection between the carbon dioxide refrigeration device body 1 and the carbon dioxide storage tank 2.

[0026] Subsequently, the carbon dioxide storage tank 2 is lifted upward by the annular handle 5 to release the adsorption of the magnetic sleeve 4, thereby directly pulling the carbon dioxide storage tank 2 out of the mounting tube 3 to replenish the carbon dioxide refrigerant. Compared with the existing carbon dioxide refrigeration device, the effect of easy disassembly and assembly is achieved, making the replenishment of carbon dioxide refrigerant simpler and more convenient to use.

[0027] Embodiment 2:

[0028] See also Figure 1 , Figure 3 and Figure 4 On the basis of the first embodiment, the right side of the carbon dioxide refrigeration device body 1 is relatively fixedly connected with a first hinge frame 13 and a second hinge frame 14, the inner side of the first hinge frame 13 is hinged with a first arc plate 15, the inner side of the second hinge frame 14 is hinged with a second arc plate 16, and the second arc plate 16 is fixedly connected with a threaded rod 17 on the side close to the first arc plate 15, the threaded rod 17 passes through the first arc plate 15, and the outer surface of the threaded rod 17 is threadedly sleeved with a fixing nut 18. The first hinge frame 13 and the second hinge frame 14 are of the same size, and the inner sides of the first arc plate 15 and the second arc plate 16 both abut against the outer surface of the carbon dioxide storage tank 2. Through the cooperation of the first arc plate 15, the second arc plate 16, the threaded rod 17 and the fixing nut 18, the carbon dioxide storage tank 2 can be clamped and fixed after the carbon dioxide storage tank 2 is installed, thereby improving its stability and avoiding the situation of tipping outward.

[0029] After the installation of the carbon dioxide storage tank 2 is completed, the staff only needs to close the first curved plate 15 and the second curved plate 16 so that the inner sides of the two are against the outer surface of the carbon dioxide storage tank 2, and then thread the fixing nut 18 onto the outer surface of the threaded rod 17 to lock the first curved plate 15 and the second curved plate 16, thereby clamping and fixing the carbon dioxide storage tank 2.

[0030] When the clamping and fixing need to be released, the staff only needs to remove the fixing nut 18 and then open the first arc plate 15 and the second arc plate 16, which is quite convenient.

[0031] Among them, a fan cover 19 is fixedly installed on the left side of the carbon dioxide refrigeration device body 1, and a fan 20 for distributing cold air is installed inside the fan cover 19. A filter screen 21 is fixedly connected to the outside of the fan cover 19. Through the cooperation of the fan cover 19, the fan 20 and the filter screen 21, the evaporator of the carbon dioxide refrigeration device body 1 can be facilitated to cooperate, so as to better distribute cold air to the outside and improve its distribution range.

[0032] At the same time, the shapes of the mounting cover 7 and the mounting seat 9 match, and the shape of the two after matching is circular.

[0033] In addition, a compressor, a condenser, an expansion valve and an evaporator are installed inside the carbon dioxide refrigeration device body 1. A protective door 22 is hinged on the front of the carbon dioxide refrigeration device body 1. A door handle and a door lock are provided on the front of the protective door 22. By providing the protective door 22, the effect of protecting the internal equipment of the carbon dioxide refrigeration device body 1 is achieved.

[0034] When in use, various devices inside the carbon dioxide refrigeration device body 1 will be started in sequence, wherein the carbon dioxide refrigerant sucked into the compressor increases its temperature and pressure through compression, thereby being converted into high-temperature and high-pressure carbon dioxide gas. Then, the high-temperature and high-pressure carbon dioxide gas enters the condenser, where it exchanges heat with the external environment, the temperature is reduced and converted into a high-pressure liquid. Subsequently, the high-pressure liquid carbon dioxide enters the evaporator through the expansion valve. During this process, the pressure and temperature of the carbon dioxide will decrease, becoming low-pressure and low-temperature carbon dioxide vapor. Finally, the low-pressure and low-temperature carbon dioxide vapor contacts the outside air in the evaporator, absorbs heat, reduces its temperature, and is converted into low-temperature and low-pressure carbon dioxide gas, which is released to the external environment.

[0035] The working principle of the above embodiment is:

[0036] When it is necessary to replenish the carbon dioxide refrigerant, the staff only needs to release the clamping ring 10 from the sleeve block 11, and then pull the plastic telescopic tube 6 upwards to pull the mounting cover 7 off the top of the mounting seat 9, so as to release the pipeline docking between the carbon dioxide refrigeration device body 1 and the carbon dioxide storage tank 2. Subsequently, the carbon dioxide storage tank 2 can be lifted upward by the annular handle 5 to release the adsorption of the magnetic suction sleeve 4, so that the carbon dioxide storage tank 2 can be directly pulled out from the inside of the mounting tube 3, and then the carbon dioxide refrigerant can be replenished. Among them, when it is necessary to install the carbon dioxide storage tank 2, the staff first needs to place the carbon dioxide storage tank 2 into the inside of the mounting tube 3, adsorb and fix it by the magnetic suction sleeve 4, and then pick up the plastic telescopic tube 6, align the bottom end of the mounting cover 7 with the top of the mounting seat 9 and place it. Subsequently, by clamping the clamping ring 10 to the outer surface of the sleeve block 11, the pipeline docking can be carried out. At this time, the sealing gasket 8 can play the role of filling the gap, thereby improving its sealing.
