Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, and more specifically, to a refrigeration device using carbon dioxide as an environmentally friendly refrigerant. Background Technology

[0002] A refrigeration device is a device used to transfer heat from a low-temperature environment to a higher-temperature environment, thereby achieving a cooling or freezing effect. It is widely used in many fields such as air conditioners, refrigerators, freezers, and industrial cooling systems. Its working principle is based on the second law of thermodynamics, which states that heat naturally flows from a high-temperature region to a low-temperature region. However, a refrigeration device transfers heat in the reverse direction by consuming energy (such as electrical energy), that is, it moves heat from a low-temperature region to a high-temperature region.

[0003] In existing technologies, low-temperature, low-pressure hydrochlorofluorocarbon (HCFC) gas is typically fed into a compressor and compressed into a high-temperature, high-pressure gas. This high-temperature, high-pressure gas then enters a gas cooler, where it releases heat to the external environment through air or water cooling, thereby lowering its temperature and transforming into a high-pressure liquid. The high-pressure refrigerant then undergoes throttling and pressure reduction via an electronic expansion valve, resulting in a rapid drop in pressure and temperature, forming a low-temperature, low-pressure gas-liquid mixture. Finally, this mixture enters an evaporator, where it absorbs heat from the cooled space and completely vaporizes, thus achieving a cooling effect. The cooled air is then delivered into the room by a refrigeration fan, completing the entire refrigeration cycle.

[0004] In practical applications, existing technologies suffer from drawbacks. Hydrochlorofluorocarbons (HCFCs) contain chlorine atoms, which can catalyze the destruction of the ozone layer, causing it to thin or develop holes, increasing ultraviolet radiation from the ground, and thus harming human health. Additionally, the small contact area of ​​the cooler can lead to poor cooling performance and affect overall performance. Therefore, a carbon dioxide-based environmentally friendly refrigerant refrigeration device is proposed. Utility Model Content

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a carbon dioxide environmentally friendly refrigerant refrigeration device, including a refrigeration body 1 and a mounting plate 101. Two mounting plates 101 are fixedly connected to the outer surface of the refrigeration body 1. A cooling chamber 201 is installed on the upper surface of the refrigeration body 1. A cooling component 2 is installed inside the cooling chamber 201.

[0030] Specifically, the cooling assembly 2 includes multiple support blocks 205 fixedly installed inside the cooling chamber 201. The upper surface of the support blocks 205 is connected to the heat dissipation fins 204. An S-shaped cooling pipe 202 is installed inside the heat dissipation fins 204. A condenser pipe 203 is fixedly connected inside the cooling chamber 201. A pipe is installed on the outer surface of the compressor 103. One end of the pipe is connected to the liquid inlet pipe of the S-shaped cooling pipe 202. The heat dissipation fins 204 are connected to the inside of the S-shaped cooling pipe 202. A carbon dioxide storage tank 207 is fixedly connected to the top of the refrigerator body 1. A connecting pipe 206 is installed on the side of the carbon dioxide storage tank 207. The connecting pipe 206 is connected to a second pipe of the compressor 103. The interior of the cooling chamber 201 is filled with coolant.

[0031] Furthermore, carbon dioxide gas is introduced from carbon dioxide storage tank 207 into compressor 103 via connecting pipe 206. Under the action of compressor 103, it is compressed into high-temperature and high-pressure gas. The high-temperature gas is transported through pipe 1 at the outlet end of compressor 103 to S-shaped cooling pipe 202 in cooling chamber 201. At the same time, condenser pipe 203 rapidly cools the coolant. S-shaped cooling pipe 202 and heat dissipation fins 204 work together to form a highly efficient heat exchange structure. S-shaped cooling pipe 202 extends the gas cooling path, while heat dissipation fins 204 significantly increase the contact area and heat exchange efficiency between gas and coolant, thereby achieving rapid cooling of high-temperature and high-pressure carbon dioxide gas.

[0032] Example 2

[0033] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, and a refrigeration component 3 is fixedly connected inside the refrigeration body 1.

[0034] Specifically, the refrigeration component 3 includes a compressor 103 fixedly connected to the upper surface of the refrigeration body 1, an evaporator 301 fixedly connected inside the refrigeration body 1, two fixed plates fixedly connected inside the refrigeration body 1, a refrigeration fan 302 installed on the side of the two fixed plates, a delivery pipe 304 installed at one end of the S-shaped cooling pipe 202, an electronic expansion valve 303 installed on the outer surface of the delivery pipe 304, one end of the delivery pipe 304 connected to the evaporator 301, two air outlet slots opened on the outer surface of the refrigeration body 1, a protective net 104 installed inside the air outlet slots, multiple mounting holes 102 installed inside the mounting plate 101, and a layer of corrosion-resistant coating applied to the outer surface of the mounting plate 101.

[0035] Furthermore, when the cooled carbon dioxide gas is transported to the evaporator 301 through the delivery pipe 304, it is throttled and depressurized by the electronic expansion valve 303 to rapidly cool the low-temperature gas, forming a low-temperature, low-pressure gas-liquid mixture, which is then continuously transported into the evaporator 301. During this process, it absorbs heat from the surrounding indoor air and completes the vaporization process. The surface of the evaporator 301 has a large heat exchange area, which further improves the heat absorption efficiency. The cooling fan 302 is installed near the evaporator 301 to force the indoor air to blow across the surface of the evaporator 301, accelerating the heat exchange between the air and the refrigerant and rapidly cooling the air.

[0036] Working principle: In use, carbon dioxide gas is first introduced from carbon dioxide storage tank 207 into compressor 103 through connecting pipe 206. Under the action of compressor 103, it is compressed into high temperature and high pressure gas. The high temperature gas is transported through pipe 1 at the outlet end of compressor 103 to S-shaped cooling pipe 202 in cooling chamber 201. At the same time, condenser pipe 203 rapidly cools the coolant. S-shaped cooling pipe 202 and heat dissipation fins 204 work together to form a highly efficient heat exchange structure. S-shaped cooling pipe 202 extends the gas cooling path, while heat dissipation fins 204 significantly increase the contact area and heat exchange efficiency between gas and coolant, thereby achieving rapid cooling of high temperature and high pressure carbon dioxide gas.

[0037] Subsequently, the cooled carbon dioxide gas is transported to the evaporator 301 through the delivery pipe 304, where it is throttled and depressurized by the electronic expansion valve 303 to rapidly cool the low-temperature gas, forming a low-temperature, low-pressure gas-liquid mixture. This mixture is then continuously transported into the evaporator 301, absorbing heat from the surrounding indoor air and completing the vaporization process. The evaporator 301 has a large heat exchange area, further improving heat absorption efficiency. The cooling fan 302 is installed in the evaporator 301 (depending on the specific installation method of the evaporator 301, electronic expansion valve 303, cooling fan 302, and compressor 103). The circuit connection method, oil circuit connection method, and control method are all conventional designs. Their specific structure and working principle are existing technologies well known to those skilled in the art, and will not be elaborated on here. The system forces indoor air to be blown over the surface of the evaporator 301, accelerating the heat exchange between the air and the refrigerant, and rapidly cooling the air. The cooled air is then sent into the indoor space through the air outlet and the protective net 104, thereby achieving a highly efficient and stable cooling effect. The carbon dioxide gas that has completed heat absorption and vaporization is then drawn back into the compressor 103 to start a new cycle. The entire device operates continuously in this manner to achieve the purpose of continuous cooling.

[0038] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
