Recently, Luen Mei Quantum has successfully passed the strict data review, on-site review, and comprehensive expert evaluation by certification authorities, and won the highest-level 5A certificate of "Clean Heating Service Certification" by virtue of its leading high-efficiency heat pump, waste heat recovery, intelligent heating and other technologies, as well as the high-level operation capability of multi-energy clean heat supply such as coal clean utilization, natural gas, and biomass.

Luen Mei Quantum is a professional clean energy operator driven by technological innovation. This company has a high-tech enterprise and post-doctoral innovation practice base in Liaoning Province. Through independent research and development, cooperative development and integrated innovation, the company has mastered and applied a number of energy-saving, environmental protection, intelligent management and control technologies, as well as a variety of energy comprehensive utilization technologies. By the end of 2019, it has 22 authorized patents, including 9 invention patents. In 2019, the company applied for 25 new patents. Seven projects are under research.

The high-efficiency heat pump technology in this certification review is a practical patented technology independently developed by Guohui Environmental Protection Company, a subsidiary of Luen Mei Quantum - thermal centrifugal water source heat pump technology. It extracts the heat of the reclaimed water treated by the sewage plant, performs the primary heating of the circulating water of the primary grid heating, and reheats the exhaust steam generated by the steam turbine driving the water source heat pump, so that the total heat utilization rate of the heating and circulating water system is greater than 100%. This technology has been applied in heat source production since 2010. It can replace coal-fired by heating along with steam waste heat. It features remarkable coal saving effect, reliable operation, high waste heat utilization rate, no emission pollution, and brings excellent social, environmental and economic benefits.

Another technology for certification and review is flue gas recycling. The new patent technology of multi-tube water surface self-shock wave gas purification invented by Guohui Environmental Protection Company removes SO2, NOx, dust and other pollutants from the flue gas discharged from the boiler, and absorbs the heat in the flue gas. The heat is extracted by a heat exchanger or water source heat pump to heat the circulating water. This technology purifies pollution emissions and recycles the waste heat of flue gas, which brings good environmental and economic benefits.

Luen Mei Quantum is a large-scale clean heating listed company in China. By the end of 2019, Luen Mei Quantum has achieved an average heating area of about 65.8 million square meters and a networking area of about 84.75 million square meters.

According to industry insiders, Clean Heating Service Certification (CHSC) is of great significance to improve the service quality of clean heating enterprises, standardize the market order, and promote the sustainable and healthy development of China's clean heating industry. Luen Mei Quantum has obtained the 5A certification for clean heating services, which represents the recognition and affirmation by the clean energy industry.
