For many years, northern China relied heavily on coal for winter heating. Every heating season brought not only thick coal smoke, but also worsening air pollution and heavier haze. As the national “dual carbon” strategy advances and clean heating policies continue to expand across northern regions, the shift from coal to electricity has become a key direction for heating upgrades. In this transformation, Foshan AIROSD Heat Energy Technology Co., Ltd. has taken a leading role. Since 2015, AIROSD has been deeply involved in the coal-to-electricity heating transition in northern China, providing reliable solutions built around the Air source heat pump, heating heat pump, heat pump system, ultra-low temperature heat pump, and home heating heat pump.
AIROSD’s Air source heat pump, heating heat pump, heat pump system, ultra-low temperature heat pump, and home heating heat pump solutions have become important forces driving the clean energy transition. The home heating heat pump has helped countless rural families say goodbye to coal smoke. Large-scale heat pump system solutions are widely used in public buildings. In extreme cold regions, the ultra-low temperature heat pump has become the preferred choice for stable and efficient heating. Across markets and projects, AIROSD’s Air source heat pump, heating heat pump, heat pump system, ultra-low temperature heat pump, and home heating heat pump have earned broad recognition for their performance and reliability.
The biggest challenge for winter heating in northern regions is system stability and heating efficiency under extreme cold conditions. Traditional heating equipment often suffers from severe capacity loss and rising energy consumption when temperatures drop below -20°C. AIROSD has spent more than ten years developing ultra-low temperature technology and has built a -35°C comprehensive performance laboratory recognized by authoritative national institutions. This laboratory is dedicated to testing the ultra-low temperature heat pump, ensuring that every ultra-low temperature heat pump can operate steadily in harsh weather.
AIROSD’s Air source heat pump uses EVI vapor injection technology and a full DC inverter system. This advanced heating heat pump can run stably at -40°C without electric auxiliary heating, while still maintaining a constant indoor temperature of 22°C. To address frosting and defrosting challenges in northern winters, AIROSD developed its own “instant defrost technology,” which monitors coil temperature in real time and determines the best defrosting moment with precision. This avoids unnecessary defrost cycles and reduces energy waste. At the same time, AIROSD has integrated AI into its heat pump system. Its independently developed “AI-based intelligent hot and cold cycle control system” has received national invention certification. This heat pump system can adjust operating parameters in real time according to weather fluctuations, reducing energy consumption by another 15% compared with previous generations. In this way, the heating heat pump is no longer just a heating device, but a smart energy manager. The reliability of the ultra-low temperature heat pump has also been widely proven in real projects.
The home heating heat pump has shown excellent results in rural household testing, where its intelligent control system makes operation easier and more convenient for users. At the same time, the energy efficiency of this heating heat pump is ahead of many comparable products. Whether it is the Air source heat pump, the heating heat pump, the heat pump system, the ultra-low temperature heat pump, or the home heating heat pump, AIROSD products continue to demonstrate strong adaptability in extreme cold environments.
Technology must ultimately serve people, and AIROSD has consistently turned technical strength into real social value. Since 2015, the company has won government coal-to-electricity heating tenders in Beijing-Tianjin-Hebei, Shandong-Jiangsu-Henan, and many other northern regions. It has successfully completed 342 national energy upgrade and renovation projects, most of which used the Air source heat pump and ultra-low temperature heat pump. From delivering more than 1,500 Air source heat pump units in 2015 to supplying more than 18,000 units in 2018, this growth reflects not only business expansion, but also the warm transformation of millions of families who have moved away from coal smoke and toward cleaner heating.
In a rural project in Fangshan, Beijing, AIROSD’s Air source heat pump reduced operating costs by more than 75% compared with electric boilers and by about 50% compared with gas boilers. This fully demonstrated the economic advantages of the heating heat pump. In Yining County, Xinjiang, a clean heating renovation project covering six townships, 20 zones, and nearly 100,000 square meters of public buildings adopted AIROSD’s heat pump system, including large ultra-low temperature heat pump units and home heating heat pump equipment. Local residents said that they no longer had to wake up in the middle of the night to add coal, and the days of irritating coal smoke were gone for good.
That project also delivered significant environmental benefits, reducing sulfur dioxide emissions by 6.84 tons, nitrogen oxide emissions by 31.65 tons, smoke and dust emissions by 64.15 tons, and carbon dioxide emissions by 6,109.85 tons each year. These achievements show the practical value of the Air source heat pump, heating heat pump, heat pump system, ultra-low temperature heat pump, and home heating heat pump in real-world clean energy transformation. Today, AIROSD products have been exported to 76 countries and regions worldwide, and the company has provided heating services for more than one million families. Among them, the home heating heat pump is especially popular in rural households, while the energy-saving performance of the Air source heat pump has earned strong praise from international users.
From Beijing Fangshan to Xinjiang Yining, from schools and hospitals to thousands of households, AIROSD has proven that a powerful ultra-low temperature heat pump can overcome climate limits, and that an AI-enabled heat pump system can deliver truly intelligent heating. Over more than a decade of work in coal-to-electricity transformation, the company has remained committed to its promise of “blue skies above, warmth below.” Whether for large public buildings or rural homes, the heating heat pump and home heating heat pump solutions from AIROSD have shown exceptional performance and long-term value.
Looking ahead, with the completion and operation of AIROSD’s green energy digital manufacturing base, the company will continue to support the upgrade of northern China’s clean heating system. More efficient Air source heat pump products, smarter heat pump system solutions, and more reliable ultra-low temperature heat pump technologies will keep entering homes, schools, hospitals, and public buildings. As AIROSD continues to improve the intelligence of the home heating heat pump and the energy efficiency of the heating heat pump, it will keep driving the future of clean heating and helping more families enjoy a cleaner, warmer winter.
