Aolan Evaporative Air Coolers——Deliver "Green Coolness" to Beijing's Above-Ground Subway Platforms

In the scorching heat of July, Beijing’s persistent sunny and high-temperature weather has made outdoor travel a true "test of endurance" for residents. Especially on semi-open above-ground subway platforms, the combined challenges of sweltering heat and direct sunlight have made waiting for trains an unbearable experience. Recently, Beijing Subway has installed Aolan evaporative air coolers at pilot stations such as Jinhai Road and Wenhua Yuan, offering an innovative "cooling through wet curtains" solution that brings noticeable temperature relief to passengers.

From "Drenched in Sweat" to "Instant Coolness": Public Needs Drive Technological Implementation.

"Sweat just keeps pouring out, especially in humid conditions where it doesn’t evaporate—it’s extremely uncomfortable." "My face keeps sweating, and I can’t even wipe it off. I don’t dare wear makeup anymore; I have to go bare-faced because makeup won’t stay on." "It’s just frustrating. I can only find a shaded spot to wait in and hope to quickly get into an air-conditioned room to cool down." Recently, Beijing TV conducted interviews at several above-ground subway stations, where residents voiced their struggles with the summer heat. As a critical node connecting suburban and urban areas in Beijing’s subway network, Jinhai Road Station features a semi-open design with platforms directly exposed to outdoor air. During summer highs, the perceived temperature often exceeds 40°C.

Addressing this public concern, Beijing Subway opted to introduce Aolan evaporative air coolers after thorough research. These units operate on the physical principle of "evaporative cooling via cooling pads," filtering and cooling outdoor air before delivering it as a "cool air curtain" at wind speeds of 3-5M per second. On-site observations revealed that each platform side is evenly equipped with six coolers, totaling twelve units across both sides, creating a comprehensive air delivery network that reduces outlet air temperatures by 5-8°C. "Stepping from the scorching street into the platform, a cool breeze hits you—it’s like opening a refrigerator door. Instant relief," shared one passenger, reflecting the cooler’s practical impact.

Technology Empowers Public Services: The "Green Code" of Aolan Coolers 

Why choose evaporative coolers over traditional air conditioning? A Beijing Subway representative explained: "Above-ground platforms are open spaces where traditional AC units are energy-intensive and less effective. Aolan’s solution requires no enclosed environment, offers low investment, rapid cooling, energy efficiency, and easy maintenance—making it the optimal choice."

From Pilot to Expansion: "Small Cool Breezes" Convey "Big Public Benefits"

In addition to Jinhai Road Station, other pilot stations like Wenhua Yuan have also completed the installation of Aolan coolers. Beijing Subway indicated that subsequent expansion plans will be evaluated based on pilot results, gradually covering all above-ground and semi-open platforms across the city.

This collaboration is not Aolan’s first venture in public transportation. As a leader in the evaporative cooling industry, Aolan’s products are widely used in major public spaces such as airports, high-speed rail stations, and bus hubs. "Public service scenarios demand extremely high equipment stability and energy efficiency. Aolan’s over two decades of technological accumulate are key to earning trust," said He Huaming, Chief Engineer and Professor-Level Senior Engineer at Aolan. He added that future efforts will focus on product optimization and exploring smart solutions integrating "intelligent temperature control + energy-efficient operation."

 As high temperatures become an urban "required course," Aolan evaporative air coolers leverage technological strength to hold up a "cool protective umbrella" for residents. From a hint of cool breeze on subway platforms to elevated public service standards, Aolan demonstrates how "small products" can address "big public needs." With the expansion of pilot projects, more residents can look forward to experiencing this "green coolness" during their travels, truly aligning technology with human needs.
