Description

Technical Field

[0001] This utility model relates to an air conditioning refrigeration system, and in particular to a workstation air conditioning system specifically designed for shoe manufacturing production lines. Background Technology

[0002] To improve working conditions in shoe manufacturing workshops during the summer, workstation air conditioners are now installed on shoe production lines. These air conditioners blow cool air to each workstation through multiple cold air outlets, improving comfort. The cooling method of these workstation air conditioners is usually the same as that of residential air conditioners: compression refrigeration. Indoor air is circulated in, cooled, and then blown out as cool air. In reality, shoe production lines generate not only heat and dust but also a significant amount of chemical odors such as glue and leather smells. Although typical workstation air conditioners have filters at the air inlet, they are almost ineffective at removing these chemical odors. The constantly circulating indoor air can even exacerbate the spread of these odors, and the cold air carrying these odors is also detrimental to the health of production workers. Furthermore, existing workstation air conditioners generally use air cooling. Although the installation structure is compact, it requires generating hot air inside the workshop and then venting it outdoors through ducts, increasing workshop noise and inevitably causing some heat to escape into the room, affecting cooling efficiency and increasing energy consumption. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a dedicated air conditioning system for shoe production lines that improves odor removal and reduces energy consumption.

[0004] This utility model includes an air conditioning unit arranged above a shoe production line. The air conditioning unit contains a compression refrigeration device. A cold air duct connected to the end of the air conditioning unit extends horizontally above the shoe production line. The cold air duct has multiple cold air outlets corresponding to each operating station. The compression refrigeration device inside the air conditioning unit is connected to a cooling tower outside the workshop through a circulating water pipe to form an external heat dissipation structure. A water curtain assembly is installed at the air inlet of the air conditioning unit. A water storage tank is located below the water curtain assembly, and a circulating water pump is located in the water storage tank. A semiconductor cooler is installed on the upper part of the air conditioning unit. The semiconductor cooler is connected to the circulating water pump through an inlet pipe and to the water curtain assembly through an outlet pipe to form an air intake cooling, dust removal, and odor removal structure.

[0005] This invention utilizes a low-temperature water curtain to remove dust, deodorize, and initially cool the air entering the air conditioning unit, resulting in a significant effect in removing chemical odors. It also improves the energy consumption of the compression refrigeration unit, providing a faster and more powerful cooling effect. Furthermore, the semiconductor refrigeration unit itself is highly efficient and consumes very little energy. In addition, this invention uses an outdoor cooling tower for water cooling, reducing workshop noise and heat, further lowering air conditioning energy consumption.

[0006] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0012] like Figures 1 to 5 As shown, the air conditioning unit 1 is arranged above the shoe production line 13. The air conditioning unit 1 contains a compression refrigeration unit 2. A cold air duct 3, connected to the air conditioning unit 1 at one end, extends horizontally above the shoe production line 13. The cold air duct 3 has multiple cold air outlets 4 corresponding to each operating station. The compression refrigeration unit 2 inside the air conditioning unit 1 is connected to a cooling tower 6 outside the workshop via a circulating water pipe 5, forming an external heat dissipation structure. A water curtain assembly 7 is installed at the air inlet of the air conditioning unit 1. A water storage tank 8 is located below the water curtain assembly 7, and a circulating water pump 14 is located in the water storage tank 8. A semiconductor cooler 9 is installed on the upper part of the air conditioning unit 1. The semiconductor cooler 9 is connected to the circulating water pump 14 via an inlet pipe 10 and to the water curtain assembly 7 via an outlet pipe 11, forming an air intake cooling, dust removal, and odor removal structure.

[0013] In this embodiment, there are two cold air ducts 3, which extend horizontally above both sides of the shoe production line 13. This allows the operating stations on both sides of the shoe production line 13 to receive cold air more closely, making them cooler, while not occupying the central space above the shoe production line 13, facilitating the arrangement of other equipment ducts. The diameter of the cold air ducts 3 gradually decreases along the horizontal extension direction, and the inner wall of the cold air ducts 3 is coated with an aerogel insulation layer, which not only provides good insulation but also ensures that the air pressure inside the duct is basically uniform, preventing insufficient airflow at the end of the duct.

[0014] When the air conditioning unit 1 is working, the compressor refrigeration unit 2 operates, and the semiconductor cooler 9 is also powered on for cooling. The circulating water pump 14 sends water from the water storage tank 8 through the inlet pipe 10 into the semiconductor cooler 9 for cooling. The low-temperature water then enters the water curtain assembly 7 from the outlet pipe 11 and is sprayed out to form a low-temperature water curtain. The water flowing down from the water curtain returns to the water storage tank 8 for circulation. The air entering at the air inlet passes through the low-temperature water curtain, which can remove dust, deodorize, and provide preliminary cooling. In particular, the effect of removing chemical odors is more obvious. Moreover, if necessary, a specific deodorizing agent can be added to the circulating water in the water storage tank 8 to further improve the deodorizing effect.

[0015] The evaporator 12 of the compressor refrigeration unit 2 is typically located behind the water curtain assembly 7. The incoming air undergoes initial cooling via the low-temperature water curtain, followed by a second cooling process through the evaporator 12, resulting in rapid cooling and low energy consumption. The cooled air is then transported by a fan to the cold air duct 3 and blown out from each cold air outlet 4. Furthermore, the condensate generated during the cooling process of the air through the evaporator 12 can be introduced into the water storage tank 8 as circulating water. The low temperature of the condensate further reduces overall energy consumption. The heat generated by the compressor refrigeration unit 2 is dissipated through the circulating water pipe 5 to the cooling tower 6 outside the workshop.
