This is not just an ordinary heating case but a successful practice of a全新的 temperature control solution based on the innovative “AC + AC Companion” system. With the rapid development of nuclear power generation and new energy power generation technologies, especially breakthroughs in molten salt reactor nuclear power technology, future electricity costs will continue to decline, and this innovative AC system is tailor-made for such a future energy landscape.
Traditional Heating Dilemmas and Innovative Solutions
Special Challenges in the Tongliao Area
Tongliao City in Inner Mongolia is located in a severely cold region of northern China, where winter temperatures often drop below -20°C. Traditional heating methods face numerous challenges:
- Limited coverage of centralized heating; rural areas mostly rely on coal-fired boilers
- Low energy efficiency of independent heating equipment, with high operating costs
- Significant decrease in heating efficiency of traditional AC units under extreme cold conditions (heating capacity decreases by 40% at -15°C)
- Comfort issues such as dust and dryness caused by direct hot air blowing
Mr. Yin’s Innovative Practice
In 2022, after learning about our “AC + AC Companion” coupled radiant system, Mr. Yin decided to install a pilot system in over 100 square meters of his home. This system consists of three core components:
- A: Traditional AC Outdoor Unit – Provides basic cooling and heating sources
- B: AC Companion – Enables secondary heat exchange and system optimization
- C: Indoor Unit – Provides convective heat exchange
System Operation Results and User Experience
