Recently, the 11th China Heat Pump Engineering Conference, themed “Heat Pump Development and Multi-Energy Complementarity,” was held in Xi'an, organized by the China Academy of Building Research and the HVAC Industry Technology Innovation Alliance. At this event, Fangkuai Boilers was awarded the title of “Outstanding Heat Pump Engineering Project” for its “Flue Gas Waste Heat Heating Project at Jilin Friendship Hospital,” once again highlighting Fangkuai's exceptional capabilities in the heat pump field.
Ms. Lu Jie, the project manager, received the “Outstanding Project Manager” award. This honor not only recognizes her leadership and execution skills but also reflects the comprehensive acknowledgment of Fangkuai's professional R&D team in project implementation and results.
In recent years, Fangkuai Boilers has consistently been at the forefront of the industry, focusing on the northern heat pump heating market. The company has concentrated its efforts in low-temperature regions such as Northeast China, North China, Shaanxi, Gansu, Ningxia, Xinjiang, and Tibet, committing to energy-saving and low-carbon solutions. Fangkuai aims to provide efficient, stable, and energy-saving clean energy heating solutions, accumulating numerous exemplary heat pump heating cases.
The flue gas waste heat heating project at Jilin Friendship Hospital was recognized as an “Outstanding Heat Pump Project” at this conference. Fangkuai equipped the project with a D6 dual-effect deep condensing hot water boiler, which reuses flue gas at 50 degrees Celsius. The gas temperature is reduced to 20 degrees Celsius using a deep cooling heat exchanger, and all absorbed heat is utilized for the heating system's return water. Coupling the boiler with the chiller improved the overall thermal efficiency by 110%, while reducing gas consumption by about 10%. This deep flue gas condensing method further absorbs heat from the flue gas, significantly reducing its moisture content, resulting in a “no visible smoke” effect when discharged into the atmosphere, thus eliminating “smoky heating.” The energy-saving and carbon reduction effects are remarkable, providing substantial ecological benefits and effectively promoting the achievement of China’s dual carbon goals.
Compared to several natural gas heating methods commonly found in cold regions, Fangkuai's D6 dual-effect deep condensing hot water boiler boasts higher energy efficiency and requires less additional space. As a modular system using chillers, it is widely applicable for retrofitting waste heat utilization across various sizes of natural gas boilers. It effectively reduces heating operational costs while ensuring user comfort and clean heating, making it suitable for long-term heating needs.
The recognition of these honors serves as motivation, encouraging us to keep moving forward. Fangkuai Boilers remains committed to green, low-carbon development, enhancing innovative R&D, and delivering high-quality products that are both comfortable and environmentally friendly, continuously contributing to the dual carbon goals. With frequent accolades, Fangkuai Boilers is not only a bearer of honors but also a carrier of value. Looking ahead, Fangkuai will continue to leverage its technological advantages, tirelessly striving to drive innovations in heat pump technology and contribute more possibilities toward a green future.
Fangkuai Boiler participated in the 8th China Heating Academic Annual Conference, held in Harbin from August 22–25, 2025. The conference featured two main forums and sixteen subforums focused on cutting-edge industry topics including cross-seasonal heat storage, smart heating, multi-source coupled heat-pump systems, and energy-saving strategies for heating networks.
