The mist cooling system at the Sanya Dream Water Park in Jiyang Town, Sanya City, Hainan Province, was designed and installed by our company. This mist cooling project consists of four parts: wall-mounted mist, ceiling mist, jungle mist, and road water flow cooling, covering a total area of 2,135 acres. It is set to become a comprehensive resort destination that integrates a wellness community, cluster-style resort hotels, world-leading water entertainment facilities, large-scale water stage performances, land parks, and jungle parks. The four cooling methods bring a refreshing breeze to the hot park and enhance the scenery. The project includes detailed design, construction, debugging, acceptance, and maintenance. Currently, the total investment for the first phase of the water park is 600 million RMB, covering 150,000 square meters. It is a super-large comprehensive water park that is open all year round, 365 days a year, both domestically and internationally. The main roads, secondary roads, and jungle paths in the park are equipped with road water flow cooling. On hot summer days, the sun heats the pavement, and wetting the surface with water effectively lowers the temperature, while the evaporation of water also reduces the surrounding temperature, allowing visitors to walk comfortably. Wall-mounted mist fans are also installed in various viewing and resting areas, so visitors can enjoy the beautiful scenery of the park without worrying about the heat. With many attractions and visitors in the park, waiting in line is inevitable. To address the heat issue during waiting times, mist cooling systems are also installed in the queue areas, ensuring that visitors' moods are not affected by the heat while waiting. The entire park is surrounded by mountains and water, and jungle mist is essential, enhancing the park's landscape while providing cooling, making the experience feel dreamlike for visitors! The urban heat island effect is becoming stronger, and using greening for cooling is not the best measure. In fact, greening cools because over 99% of the energy is dissipated as latent heat due to water evaporation, while mist cooling is much more efficient. However, mist cooling in public places requires high water quality. The urban heat island effect is mainly influenced by the following factors: reduced evaporation, decreased reflection of urban surfaces, and energy input. The intensity of the impact is as follows: a reduction in evaporation of 0.05g/s㎡ results in a heat input of 120.9w; a 10% decrease in urban surface reflectivity results in a heat input of 30w/㎡; and an artificial energy input of 10w/㎡ leads to a total heat input increase of 160.9w/㎡ in the city. Due to the influence of air convection, the actual heat input is about 20w/㎡, resulting in a calculated temperature rise of about 3.5℃, which is consistent with actual comparisons. When air circulation slows down in summer, heat input can increase sharply. Due to the low adaptability of urban evaporation systems, urban temperatures can rise sharply, while the accelerated operation of air conditioning and thermal power plants can create a vicious cycle, exacerbating urban atmospheric warming. From this data, it can be concluded that the best way to solve urban atmospheric heat pollution is to increase evaporation. Given the limitations of urban installations, using a mist system is an efficient and economical solution. When the evaporation rate is 0.05g/s㎡ (equivalent to 2mm of rainfall over 11 hours during the day), the average atmospheric cooling can reach 7℃. Mist cooling has been applied for a long time; a solution for large-scale outdoor mist cooling systems was proposed as early as 2002, but the first large-scale application was at the Aichi Expo in Japan, with the most successful application at the 2010 Shanghai Expo. The folding landscape and moisture-retaining mist can be both light and ethereal, as well as vast and expansive. They can create their own scenery or combine with various elements such as water systems, rockeries, greenery, and lighting, resulting in diverse forms that complement each other. Their ever-changing forms and functions will add more ink wash elements to the landscape aesthetics of Chinese gardens. Their unique moisture-retaining function can better support the care and growth of plants. Improving the air quality of small environments involves treating raw water through professional water treatment, and the mist effect generated by high-pressure micro-pore impact technology can produce a large number of negative ions, known as "air vitamins," creating a unique "forest oxygen bar" in the city, improving air quality and benefiting physical and mental health. The cooling mist, composed of mist molecules, can effectively absorb heat from the air and lower the local environmental temperature. Its low operating costs and effective cooling effects have been widely used and recognized at expos and many attractions, becoming a new element for outdoor cooling in public spaces and communities.
