[0002] Air refrigeration technology has been mastered by people for a long time. As early as 1844, the United States manufactured the first air refrigerator. The cycle used the reverse Brayton cycle. At that time, due to the limitations of the equipment manufacturing process, its refrigeration efficiency was lower than that of the vapor compression refrigerator. With the continuous development of turbine machinery and the improvement of refrigeration efficiency, this refrigeration system has received more and more attention and has a good development prospect. The research on inert gases has also attracted much attention. Inert gases can not only be used as a working fluid for refrigeration in the reverse Brayton cycle, but also have the effect of inhibiting photosynthesis and preserving food. Inert gases can isolate food from oxygen, allowing it to be stored for a longer time.

[0003] Traditional refrigeration systems use Freon as a refrigerant and Freon as a refrigerant to operate a year-round cooling system, which can keep food fresh for a short period of time. However, bacteria carried by the food itself, as well as cold storage rooms, refrigeration equipment and preservation equipment, can also breed bacteria, which can easily cause the food to be kept fresh for too short a time.

[0004] Accordingly, the art needs a new refrigeration system using inert gas as a working fluid to solve the above problems. Summary of the invention

At the same time, by setting the first valve and the second valve to control the delivery amount of the inert gas and ozone gas, the first inert gas bottle or the second inert gas bottle can be selectively closed to achieve the purpose of using one inert gas bottle and keeping the other inert gas bottle in reserve.

[0038] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principle of the refrigeration system using inert gas as working fluid of the present invention, and are not intended to limit the protection scope of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0040] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] Air refrigeration technology has been mastered by people for a long time. As early as 1844, the United States manufactured the first air refrigerator. The cycle used the reverse Brayton cycle. At that time, due to the limitations of the equipment manufacturing process, its refrigeration efficiency was lower than that of the vapor compression refrigerator. With the continuous development of turbine machinery and the improvement of refrigeration efficiency, this refrigeration system has received more and more attention and has a good development prospect. The research on inert gases has also attracted much attention. Inert gases can not only be used as a working fluid for refrigeration in the reverse Brayton cycle, but also have the effect of inhibiting photosynthesis and preserving food. Inert gases can isolate food from oxygen, allowing it to be stored for a longer time.

[0042] Traditional refrigeration systems use Freon as a refrigerant and Freon as a refrigerant to operate a year-round cooling system, which can keep food fresh for a short period of time. However, bacteria carried by the food itself, as well as cold storage rooms, refrigeration equipment and preservation equipment, can also breed bacteria, which can easily cause the food to be kept fresh for too short a time.

[0043] In order to solve the above problems, the present application provides a refrigeration system using an inert gas as a working fluid, the system comprising an inert gas storage component 1, a heat exchange component 2 and a turbocharger component 3. The inert gas storage component 1 stores inert gas and ozone gas, the inert gas storage component 1 is connected to the heat exchange component 2, the heat exchange component 2 is connected to the turbocharger component 3, and the expansion port 331 of the turbocharger component 3 is located indoors for cooling.

[0044] The refrigeration system using inert gas as the working fluid provided in the present application stores inert gas and ozone gas inside the inert gas storage component 1, and brings the ozone gas into the refrigeration equipment together with the inert gas as the working fluid. Since the ozone gas can disinfect and sterilize, the bacteria carried on the surface of the food and the bacteria grown in the refrigeration equipment are eliminated, thereby increasing the shelf life of the food.

[0045] Combine the following Figure 1 and Figure 2 The refrigeration system of the present application using inert gas as working fluid is described.

[0046] See also Figure 1 and Figure 2 The present application provides a refrigeration system using an inert gas as a working fluid, which generally includes an inert gas storage component 1, a heat exchange component 2, and a turbocharger component 3. The inert gas storage component 1 stores inert gas and ozone gas, the inert gas storage component 1 is connected to the heat exchange component 2, the heat exchange component 2 is connected to the turbocharger component 3, and the expansion port 331 of the turbocharger component 3 is located indoors for cooling.

[0047] In this way, by storing inert gas and ozone gas inside the inert gas storage component 1, and taking the ozone gas into the refrigeration equipment with the inert gas as the working fluid, since the ozone gas can disinfect and sterilize, the bacteria carried on the surface of the food and the bacteria grown in the refrigeration equipment are eliminated, so the food preservation time can be increased. The inert gas circulates in the system, takes away the heat in the working environment, and forms an inert gas working environment. The use of inert gas is pollution-free to the environment. As a refrigerant, it does not damage the ozone layer and has little impact on global warming. It is easy to obtain. Most of the air is nitrogen, which is widely present in the atmosphere and easy to obtain. It also has the effect of inhibiting photosynthesis and preserving freshness, and can be used in specific occasions. It is highly safe. The inert gas has high stability, is non-flammable, non-explosive, and is not dangerous to the environment when a leak occurs. In addition, the chemical properties of the inert gas are very stable, and the stability and durability are good.

[0048] In addition, by directly arranging the expansion port 331 of the turbocharger assembly 3 indoors, indoor cooling and sterilization can be achieved without other devices, thus saving costs.

The specific use method can be determined according to actual conditions.

[0053] In this embodiment, optionally, inert gas and ozone gas are stored inside the first inert gas bottle 11 and the second inert gas bottle 12. The inert gas is generally nitrogen, but is not limited to nitrogen. Adding a certain proportion of ozone gas to nitrogen can disinfect and sterilize, so that bacteria carried on the surface of food and bacteria grown in refrigeration equipment can be eliminated, thereby increasing the shelf life of food.
