Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary components for refrigeration equipment, specifically to a refrigerant leakage monitoring bracket for refrigeration equipment. Background Technology
[0002] In the field of refrigeration equipment, refrigerant is the core medium for realizing the refrigeration cycle, and its normal operation is crucial for maintaining equipment performance. However, in actual use, refrigerant leaks may occur in refrigeration equipment. Once a leak occurs, it will not only lead to a decrease in cooling effect and affect the normal operation of the equipment, but may also cause a series of serious problems.
[0003] From an environmental perspective, many common refrigerants, such as Freon-like substances, are destructive to the atmosphere. For example, the chlorine atoms in Freon destroy the ozone layer, leading to ozone holes and exacerbating global climate change. Furthermore, Freon is a potent greenhouse gas, with a greenhouse effect far exceeding that of carbon dioxide; large-scale leaks significantly increase greenhouse gas emissions, negatively impacting the environment. From a safety perspective, while some newer refrigerants with low global warming potential have improved environmental performance, some are still flammable. When these flammable refrigerants leak, they can rapidly accumulate in confined or poorly ventilated spaces. Once they reach a certain concentration, exposure to ignition sources or static sparks can trigger serious safety accidents such as combustion or explosion, threatening lives and property. From the perspective of equipment maintenance and operating costs, refrigerant leaks gradually reduce the amount of refrigerant in equipment, leading to abnormal pressure in the refrigeration system, increased compressor load, and other problems. This shortens equipment lifespan and increases maintenance costs and energy consumption. Moreover, timely detection and handling of refrigerant leaks can prevent economic losses such as production interruptions due to equipment failure.
[0004] Currently, although some refrigerant leak detection methods exist in the market, most have certain limitations. For example, traditional manual inspection methods, such as using soap bubble detectors or halogen leak detectors, are inefficient and insufficient for detecting minute leaks, making them unsuitable for practical needs. Moreover, these methods often cannot monitor refrigerant leaks in real time and continuously, making it difficult to detect potential leaks in a timely manner. Therefore, developing a monitoring bracket that can effectively and promptly detect refrigerant leaks in refrigeration equipment is of significant practical importance. Utility Model Content

[0024] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of each embodiment. Specific details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures. The disclosures of various publications, patents, and published patent specifications cited herein are incorporated herein by reference in their entirety. The technical solutions of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.
[0025] Example 1: A refrigerant leak monitoring bracket for refrigeration equipment includes a refrigeration unit 1 and a monitoring frame 2. The frame 11 of the refrigeration unit 1 is welded from steel and has an overall rectangular structure. The lower left side of the inner cavity of the frame 11 is bolted to the condenser unit 12, the top left side of the frame 11 is bolted to the evaporator unit 15, the middle section of the inner cavity of the frame 11 is bolted to the compressor 13, and the right side of the inner cavity of the frame 11 is bolted to the liquid receiver 14. The condenser unit 12, compressor 13, liquid receiver 14 and evaporator unit 15 are connected by copper pipes to form a refrigeration cycle system.
[0026] The rectangular frame 21 of the monitoring frame 2 consists of a rectangular steel frame and several X-shaped reinforcing bars. The rectangular steel frame is welded from angle steel, and the X-shaped reinforcing bars are welded from flat steel to the side walls of the rectangular steel frame to enhance the structural strength of the rectangular frame 21. The bottom surface of the rectangular frame 21 is bolted to the top surface of the frame 11, covering the components on the upper surface of the frame 11. The top surface of the rectangular frame 21 is bolted to a gas collection hood 23. The top of the gas collection hood 23 has a through hole, in which a gas detector 24 is embedded and fixed to detect the composition and concentration of the gas inside the gas collection hood 23. Six top-level fans 22 are bolted to the bottom port of the gas collection hood 23. The six top-level fans 22 are interconnected and arranged in a linear array to extract the gas volatilized after the refrigerant inside the refrigeration equipment 1 leaks.
[0027] A connecting frame 28 is bolted to the rear end face of the frame 11. Ten side fans 27 are bolted to the lower rear side of the rectangular frame 21, with the front end face of each side fan 27 fixedly connected to the rear end face of the connecting frame 28. The side fans 27 are fixedly connected to each other and arranged in a linear array. A square cover 26 is bolted to the rear side of each side fan 27. Both the square cover 26 and the gas collection cover 23 have round holes on their rear sides. The two ends of the air guide pipe 25 pass through these two round holes and are sealed by sealing rings installed inside the round holes. The gas drawn by the side fans 27 is introduced into the gas collection cover 23 for detection by the gas detector 24. When a refrigerant leak occurs in the refrigeration equipment 1, the top fan 22 and the side fans 27 start, drawing the leaked refrigerant vapors into the gas collection cover 23. The gas detector 24 monitors the gas composition and concentration in real time. Once a refrigerant leak is detected, an alarm signal is issued to notify relevant personnel for handling.
[0028] Example 2: This example is structurally similar to Example 1, except for the number of top-level fans 22 and side fans 27 in the monitoring frame 2. In this example, eight top-level fans 22 are bolted to the bottom port of the gas collection hood 23. These eight top-level fans 22 are interconnected and arranged in a linear array to enhance the extraction capability of leaked gas from the top of the refrigeration equipment 1. Twelve side fans 27 are bolted to the lower rear side of the rectangular frame 21. These twelve side fans 27 are interconnected and arranged in a linear array. The extracted gas is guided into the gas collection hood 23 through the square cover 26 and the gas guide pipe 25. This design is suitable for situations where the refrigeration equipment 1 is large and the risk of refrigerant leakage is high. By increasing the number of top-level fans 22 and side fans 27, the extraction efficiency of leaked gas is improved, enabling the gas detector 24 to detect refrigerant leakage in a timely and accurate manner, ensuring the safe operation of the refrigeration equipment 1.
[0029] Example 3: This example is also based on the structure of Example 1, but the installation method of the monitoring frame 2 is improved. When installing the monitoring frame 2, the bottom surface of the rectangular frame 21 is first initially fixed to the top surface of the frame 11 with bolts. The position of the rectangular frame 21 is adjusted so that it completely covers the components on the upper surface of the frame 11, and then the bolts are tightened for fixation. For the installation of the top-level fans 22 and the side fans 27, six top-level fans 22 are first fixedly connected to each other and arranged in a linear array, and then fixed to the bottom port of the gas collection hood 23 with bolts. After ten side fans 27 are fixedly connected to each other and arranged in a linear array, their front end faces are fixedly connected to the rear end face of the connecting frame 28 with bolts, and then the square cover 26 is connected to the rear side of the side fans 27 with bolts. Finally, the two ends of the air guide pipe 25 are respectively passed through the round holes on the rear side of the square cover 26 and the gas collection hood 23, and a sealing connection is achieved through the sealing ring installed inside the round hole. This installation method facilitates the assembly and debugging of the monitoring frame 2. During installation, the positions of each component can be adjusted according to the actual situation, ensuring that the monitoring frame 2 can operate stably and reliably, effectively monitoring refrigerant leakage in the refrigeration equipment 1.
[0030] Based on the above preferred technical solution, the workflow of this technical solution is described as follows: When the refrigeration equipment 1 is working normally, its internal condenser unit 12, compressor 13, liquid receiver 14, and evaporator unit 15 are connected by pipelines to form a refrigeration cycle system, maintaining the refrigeration function. When the refrigeration equipment 1 experiences a refrigerant leak, the leaked refrigerant will evaporate into gas. At this time, the monitoring frame 2 starts working, and the side fan 27 at the bottom of the rectangular frame 21 starts. Since the front end face of the side fan 27 is fixedly connected to the connecting frame 28 on the rear end face of the frame 11, the side fan 27 can extract the gas evaporated after the refrigerant leaks from inside the refrigeration equipment 1. After the gas is extracted, it enters the square cover 26.
[0031] Simultaneously, the top-level fan 22, fixed in the bottom port of the gas collection hood 23, also starts. Six to eight top-level fans 22 are fixedly connected to each other and arranged in a linear array. They extract the gas that evaporates after refrigerant leakage from the top area of the refrigeration equipment 1. The gas extracted by the side fans 27 is transported through the air guide pipe 25 connecting the rear side of the square cover 26 and the rear side of the gas collection hood 23. The two ends of the air guide pipe 25 pass through the round holes opened on the rear side of the square cover 26 and the gas collection hood 23. The sealing rings installed in the round holes ensure that there is no leakage during the gas transportation process. The gas is finally guided into the gas collection hood 23. The gas extracted by the top-level fans 22 enters the gas collection hood 23 directly.
[0032] As the top-mounted fan 22 and the side fans 27 continue to operate, more and more leaked gas is collected in the gas collection hood 23. A gas detector 24, fixedly embedded in the top surface of the gas collection hood 23, begins to detect the gas inside. The gas detector 24 communicates with the interior of the gas collection hood 23 through a through-hole in the top, enabling real-time detection of the gas composition and concentration. When the gas detector 24 detects that the refrigerant composition and concentration in the gas inside the gas collection hood 23 reach a preset alarm threshold, it indicates a refrigerant leak in the refrigeration equipment 1. The gas detector 24 will issue an alarm signal, which can be transmitted to relevant monitoring systems or notify relevant personnel for timely inspection and maintenance of the refrigeration equipment 1, preventing further refrigerant leakage and ensuring the safe operation of the refrigeration equipment 1 and the safety of the surrounding environment.
[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
