Shenzhen Luohu Railway Station is located in the Luohu District of Shenzhen City, Guangdong Province, right next to the Luohu Port. It is the southern terminus of the Guangzhou-Shenzhen Railway. Established in 1950, it is under the jurisdiction of the Guangzhou Railway (Group) Company and is currently a direct first-class station. It connects to the Beijing-Guangzhou and Beijing-Kowloon railways to the north via the Guangzhou-Shenzhen Railway, and to the south, it connects to the Kowloon-Canton Railway in Hong Kong, just a bridge away from Hong Kong and closely linked to the Shenzhen Luohu Port. It serves as an important hub connecting the mainland with Hong Kong and Macau, as well as China with the world, and is the second-largest railway station in Shenzhen. In response to the high density of passenger flow and the large area of the station, traditional cooling methods are not suitable. The company has brought a popular solution—landscape misting. Artificial mist aims to cool down, beautify the environment, improve air quality, and create suitable ecological and working conditions. It is widely used in parks, stage settings, leisure areas, greenhouses, workshops, and mines, and is favored by many. Artificial mist is generated by a specially developed misting machine that purifies and sterilizes water, pressurizing it to above 4.0 MPa. High-pressure pumps and pipelines then force the high-pressure water through a gem impact nozzle, altering the velocity distribution of the jet stream. This process breaks larger liquid droplets into smaller ones, which are further atomized into countless fine mist particles with diameters ranging from 1 to 20 microns, also known as "micro mist" or "cold mist." With the rise of mist cooling equipment, more and more public places are adopting this method. The installation of mist cooling devices is characterized by durability, efficiency, convenience, and energy savings, with relatively low investment costs. These features have led to increased attention and wider application of mist cooling devices. After several years of development, mist cooling equipment has become more user-friendly, allowing for different types of mist cooling devices to be used in various environments. The working mechanism of artificial mist nozzles can be divided into two main categories: the conventional centrifugal nozzle, which uses lasers to drill holes in a special super-hard alloy, and has a precision stainless steel piston behind the small hole. Driven by high-pressure water flow, the piston moves at high speed, tearing the water into extremely fine droplets that are sprayed out as mist. This type of nozzle has a wide range of applications. The other type is the impact nozzle, where high-speed water flow strikes a very fine needle tip, shattering into mist. This type of nozzle is most suitable for creating artificial mist landscapes due to its large mist output. Artificial mist is widely used in parks, stage settings, leisure areas, greenhouses, workshops, and mines, aiming to beautify the environment, improve air quality, and create suitable ecological and working conditions. While beautifying the environment, it can also generate a large number of negative ions, increasing the negative ion content in every milliliter of air to between 100,000 and 500,000, which is 1,000 to 5,000 times that of ordinary urban residential areas, effectively improving the activity environment. Due to the large evaporation area of the water mist, suspended dust in the air is captured by the floating water mist and falls to the ground, achieving dust removal and air purification. When it comes into contact with dry, hot air, it evaporates instantly, taking away a large amount of heat in the process, providing excellent cooling effects during hot seasons.
