Micoe Heat Pump Passes Extreme Cold Test in Mohe, China’s “Cold Pole,” Receives Industry-First Certification

The 2026 Heat Pump Industry Annual Conference and Heat Pump Industry High-Quality Development Conference was recently held in Yantai, Shandong Province. Hosted by the China Refrigeration and Air-Conditioning Industry Association (CRAA), the event brought together representatives from government, industry associations, universities, research institutes, and leading enterprises to discuss technological innovation and high-quality development in the heat pump sector.

Micoe was invited to attend and, based on the proven performance and stable operation of its integrated air source heat pump heating system under extreme conditions, successfully received the prestigious “In-Service Operation Evaluation / Long-Term Reliability Certification” for air conditioning units and heat pump systems.

A Certification That Goes Beyond the Lab

This certification, jointly issued by the Hefei General Machinery and Electrical Products Inspection Institute and the National Compressor and Refrigeration Equipment Quality Inspection Center, is one of the most authoritative certifications for in-service heat pump projects in China. Unlike traditional laboratory testing, this certification employs a rigorous on-site monitoring system that tracks equipment performance over full operating cycles, under extreme weather events, and through frequent start-stop conditions — delivering results that reflect real-world applications.

The Mohe Challenge: Where Winter Temperatures Drop to -53°C

To verify the extreme cold adaptability of its integrated heating system, Micoe chose Mohe — known as China’s “North Pole” — as its testing ground. The project was commissioned in September 2025 and has faced three simultaneous challenges: extreme low temperatures, high load fluctuations, and long-term continuous operation.

After months of on-site monitoring, the system met all performance requirements under GMPI01-01-2017 standards. Even when outdoor temperatures dropped to approximately -40°C, the system maintained stable 35°C hot water output, delivering consistent indoor comfort.

Key Performance Data

• Stable heating water output at 35°C even at -40°C ambient temperature
• No equipment failure throughout the entire monitoring period
• Heating energy consumption monitored at 0.339 kWh/(d·m²) 
• Indoor temperature maintained at 20°C+ with outdoor temperatures ranging from -34°C to -42.4°C

Economic and Operational Advantages

• 55% reduction in annual heating costs compared to municipal heating
• 45% lower initial investment compared to municipal heating connection fees
• Integrated with CAS (Clean Energy AI Operating System) smart controls for optimized performance

A Record of Extreme Environment Performance

Micoe’s commitment to extreme climate heating goes beyond Mohe. In 2022, its heat pumps were deployed at the Great Wall Station in Antarctica, marking the first time an air source heat pump was used on the continent. The company is also a partner of China’s Polar Research Institute and China’s Aerospace Program, with its heat pumps now operating at both the Great Wall and Zhongshan Stations in Antarctica.
