The Jiuhua Communication Programmable Fountain is located in the Haicang Industrial Zone of Xiamen City. Construction began in October 2017 and was completed and accepted for use in December of the same year. This fountain uses a program control system provided by Xiamen Guanyu Technology Co., Ltd., which offers equipment manufacturing, installation, debugging, and maintenance services. The fountain's nozzles and pipes are made of 304 stainless steel, the pumps are of the SP series 304 stainless steel, the cables are specialized underwater waterproof cables of model JHS, and the frequency converters and electrical components are from Schneider. The programmable control system utilizes our company's latest developed multimedia intelligent program control system. The programmable fountain is controlled by programming the control program according to pre-set water patterns. The computer runs the program to send control signals, allowing for various changes in water patterns and lighting. The program can generally be modified at any time and can store multiple programs for easy retrieval. The advantages of this programmable fountain include moderate cost and a wide variety of program changes. The PLC program is pre-programmed for the combinations of water patterns and lighting changes, and during operation, this program is converted into signals to control the pumps, frequency converters, CNC valves, lights, and other components, creating a crystal-clear, colorful, and dynamic water and light effect. This makes the fountain performance more vivid, rich in connotation, and showcases the art of water.

Xiamen Guanyu Technology Co., Ltd. has passionately created a mist cooling system project for the Tianbao service area of the Sinopec gas station, located at the Jinshan service area on the Xiarong Expressway in Zhangzhou's Nanjing County. This mist cooling project upgrades and transforms our complete set of mist cooling, dust removal, anti-static, and explosion-proof systems to address the challenges of heat during the scorching summer for employees and to enhance dust and static electricity prevention at the gas station. This system brings a refreshing coolness to the hot summer weather. Given that vehicles entering the service area for refueling generate a lot of heat, especially during summer when queues can lead to on-site temperatures often reaching around 40 degrees Celsius, high temperatures can be detrimental to the health of the fuel attendants, and the heat can also irritate customers. The mist cooling system is the best tool to address this situation. The principle of mist cooling utilizes the natural climate regulation of water, employing atomization to cool the air. Water is sprayed in a fine mist, dispersing droplets in the air. As the mist vaporizes, it absorbs a significant amount of heat, achieving rapid cooling. Simultaneously, it exchanges heat and moisture with the moving air, where the mist particles absorb heat (or sensible heat) from the air, vaporize, and evaporate, increasing the humidity of the air and thus humidifying it. Additionally, it removes impurities and dust from the air, accelerates air flow, neutralizes excess positive ions in the air, and increases the content of negative ions, making the air fresh and pleasant, greatly improving the working and living environment. The mist cooling system is designed to be healthy and environmentally friendly, focusing on fresh health, low carbon, and intelligent living. It aims to create scenery, cool the air, humidify, remove dust, disinfect, prevent static electricity, and promote health. By using high-pressure water treatment and atomizing nozzles, water is instantly split into billions of micron-sized water molecules, forming a structure similar to clouds and mist, which can naturally float in the air, providing a refreshing and natural feeling akin to being in a forest. People can walk through it and feel the moisture without easily getting their clothes wet, creating a delicate, natural, and perfect experience. It can be used as a standalone feature or in conjunction with other related landscape elements. The mist cooling machine uses water as its raw material and employs HP-2N biofilm technology for water treatment, filtering out all harmful active components, ensuring that the water used in the mist system is safe for human health. Additionally, due to the high-pressure impact atomization method, the mist system not only generates mist particles but also releases a large amount of what is known as "air vitamins"—negative ions, which are 2000-5000 times more than those found in ordinary urban environments, enhancing human immunity and benefiting physical and mental health. Furthermore, it has functions for humidity control, dust removal, cooling, and odor control, effectively improving the surrounding environment. The mist cooling system is controllable and convenient. To achieve controllable and convenient mist effects, the main system adopts centralized integrated control, which can be customized according to customer needs, featuring automatic program settings and remote control systems. It utilizes a human-machine interactive interface, focusing on user-friendly control. The system can generate mist instantly within 1-5 seconds, making large-scale and immediate mist effects possible. The mist cooling system is environmentally friendly. In terms of materials, the nozzles of the mist cooling machine are embedded with ruby, achieving 100,000 hours of zero wear, and the components are made of stainless steel. The overall system pursues high stability, reduces later maintenance costs, and ensures a long service life. Regarding usage costs, a 220-meter mist strip consumes 3.16 tons of water per day and 10.67 kWh of electricity per day (calculated based on the regular operation time of the mist being on for 10 minutes per session, 16 times a day), achieving high savings in water and electricity. In terms of noise control, ordinary equipment does not exceed 60 decibels, and special requirements can be accommodated with soundproofing; all pipes, nozzles, and connectors are made of 304 stainless steel, ensuring easy layout and durability. The user-friendly design of the electric spray cabinet guarantees an aesthetically pleasing overall appearance. The mist cooling system is backed by mature experience. The high-pressure pump products stem from extensive experience, which has been cultivated through years of relentless effort. After years of exploration and research in the mist field, mist cooling has established its technological advantages in this domain.

Fountains transform still water into flowing water, giving the water a soul. Coupled with various lighting effects, they endow the water with rich and colorful forms. Fountains can soften and buffer the "solid buildings" and hard surfaces in the city, enhancing the vitality of the urban environment, benefiting both physical and mental health, and satisfying the needs of visual art.
