AIROSD Ultra-Low Temperature Hot Water Units Empower Changbai Mountain Naitoushan Village Hot Spring Resort, Setting a New Wellness Benchmark in Extreme Cold Regions
At the foot of Jilin's Changbai Mountain, a hot spring resort hotel blending natural wonders with modern technology captivates global tourists. As the region's first premium integrated resort combining business, banquets, leisure, entertainment, wellness, and research functions, the Changbai Mountain Naitoushan Village Hot Spring Resort has, since its winter 2024 opening, relied on AIROSD ultra-low temperature hot water units for stable thermal energy. This enables year-round operation of indoor heated pools and outdoor hot spring baths even in -40°C extremes, establishing it as a benchmark in Northeast Asian wellness tourism.
Technological Breakthrough Against Extreme Cold
Renowned as a "winter wonderland," Changbai Mountain's harsh cold poses severe challenges for hotel operations. Traditional heating systems experience efficiency drops below -20°C, while Naitoushan frequently hits -30°C to -40°C. Ensuring stable hot spring operation was critical. AIROSD's team developed a bespoke ultra-low temperature air source heat pump solution. The core units feature vapor injection technology and an intelligent defrost system, enabling stable heating at -40°C with outlet water up to 65°C. This perfectly meets the precise temperature control needs of the Swimming pool heat pump system maintaining indoor pools at 28°C±1°C and the outdoor hot spring baths at 40°C±1°C.
Eight AIROSD ultra-low temperature hot water units operate in modular combination, achieving dynamic balance between heat output and energy consumption. Compared to traditional electric heating, this Pool heat pump System achieves a comprehensive COP exceeding 3.2, reducing annual energy consumption by approximately 60% – equivalent to cutting 1,200 tons of CO2 emissions. This not only validates AIROSD's leadership in clean energy but also significantly lowers hotel operating costs, providing dual competitive advantages in price and sustainability.
Hardware Foundation for Immersive Wellness
The 48,000 sqm hotel features 127 panoramic rooms and 23 mountain villas. To realize the "hot springs year-round" concept, it includes 3 indoor heated pools (850 sqm total) and 11 outdoor hot spring baths (2,100 sqm total). The AIROSDPool heat pump System employs a dual-loop circulation design, limiting water temperature fluctuations to within ±0.5°C. Combined with 24/7 water quality monitoring and UV sterilization, it ensures a safe, comfortable wellness environment.
Notably, the outdoor bath area uses buried pipelines, with the Air source swimming pool heat pump units housed 5 meters underground. This protects equipment from physical damage by extreme cold while noise reduction technology keeps operational sound below 45 dB. This "invisible" engineering seamlessly integrates the hot springs with Changbai Mountain's pristine forest landscape, making it a popular attraction.
Innovation Behind the Industry Benchmark
The project's success stems from AIROSD's deep understanding of Northeast China's severe cold market needs. After 18 months of field surveys and data modeling, the team optimized the fin-tube heat exchanger structure for Changbai's high winds and low humidity, improving defrost efficiency by 30%. A smart cloud-control platform enables remote parameter adjustment and fault prediction, drastically cutting maintenance. Hotel engineering data shows a remarkably low failure rate of just 0.3% since November 2024 system launch.
The demonstration effect is clear: by winter 2025, three new premium hotels in Changbai Mountain launched tenders specifying "ultra-low temperature operation capability" as a core requirement. Experts note the AIROSD Naitoushan project validates the commercial viability of Air source swimming pool heat pump technology in extreme cold, providing an innovative clean heating solution for northern regions under the "Dual Carbon" goals.
Conclusion: Technology Empowers Nature, Reshaping Tourism
The successful operation of Changbai Mountain Naitoushan Village Hot Spring Resort marks the arrival of the "precision temperature control era" for China's premium wellness tourism. AIROSD's technological innovation overcomes geographical barriers, transforming Changbai's snow and ice into sustainable energy. It not only creates a spring-like experience year-round for guests but also sets an industry benchmark for integrating green building with smart energy, like the High Temp swimming pool heat pump. As the extreme cold tourism market grows, this case may pioneer a new chapter in global premium resort energy system upgrades, potentially integrating Solar heat pump for pool technology for further efficiency.
