Ultra-low temperature air source heat pump—–the ultra-low temperature heat pump heating project of Beijing Fund Town International Conference Center was put into operation at the end of December 2016, and has been in perfect operation for 2 months.
Project introduction
Beijing Fund Town is located in Fangshan District of Beijing, with a total area of 18 square kilometers. This town has been listed in the 13th Five-Year Plan of Beijing, which is a key project for Beijing to promote the coordinated development of Beijing, Tianjin and Hebei. It has been selected as the first batch of towns with Chinese characteristics, and will be built into an international financial town with ecological and environmental protection, smart technology, livability and industry integration.
Project details
Ultra-low temperature air-source heat pump is used in Beijing Fund Town, which integrates many patented technologies. After on-the-spot investigation and careful layout, the professional and technical personnel of air source heat pump finally determined that the project adopts 20 heat pump units (40 machines), with a heating area of 32,000 ㎡, and the system stability of the project is high, which has been running smoothly for 2 months.
Project technology
Ultra-low temperature air source heat pump is used in the temperature range of -25℃~45℃, and adopts the special compressor of American valley wheel ZW-KS heat pump, which has a long service life. Self-developed high-efficiency defrosting system, with COP as high as 2.0 at -20℃, has applied for national and international invention patents. Won the honorary certificate of “National Key New Product” jointly issued by the Ministry of Science and Technology, the Ministry of Environmental Protection, the Ministry of Commerce and the General Administration of Quality Supervision, Inspection and Quarantine. The system adopts intelligent terminal control system, which runs intelligently, is stable and safe, can save about 40% of energy consumption, and fully meets the heating requirements of safety, stability, energy conservation and environmental protection.
Project prospect
At present, China is in the stage of insufficient energy supply. The application of air-source heat pump equipment will completely improve this situation and alleviate the development pressure brought by environmental pollution. Advanced design, wide application range and stable unit operation performance all indicate that air energy will have a better development prospect in China. In recent years, with the deepening promotion and implementation of the national energy conservation and emission reduction policy, air energy, a new energy conservation and environmental protection product, has attracted the attention of the state and is favored by more and more consumers. In 2016, the sales volume of China’s air source heat pump industry exceeded 10 billion yuan. 2017 is regarded as the golden period for the development of domestic air energy industry. On the one hand, after more than ten years of development, the scale of the industry and the strength of enterprises in the industry have been qualitatively improved, and more and more enterprises have begun to take on the important task of promoting the sound development of enterprises. On the other hand, with the attention and support of the state for energy-saving and low-carbon industries, the heating market has become a major breakthrough for the industry chassis to become bigger. Especially in the past, the running obstacle of air-energy heat pump in the low temperature environment in northern winter is gradually being solved, and air-energy heat pump heating has become the general trend. Developing a low-carbon economy is not only an inevitable requirement for effectively utilizing resources and reducing environmental pollution, but also an effective way to adjust and optimize the economic structure and transform the economic development mode. The brand of air energy water heater is gradually valued by major enterprises in China, and air source heat pump water heater will become the mainstream product in the future water heater market. Air can be used for heat pump heating, which does not consume coal, but only electric energy and air energy. There is no waste gas and no environmental pollution in the heating process; The heat pump uses the free energy in the air to heat, and the heating efficiency is as high as 400%, which saves 75% energy than the electric heater, and fully reduces the heating expenses of residents; In the heating process, water and electricity are separated, and the compressor is not in contact with water, thus effectively eliminating the danger of electric shock and further improving the safety factor.
