Recently, the column of "Model Laishan" official account [Be Vigorous and Strive to Benefit Enterprises] focused on Yantai Land Air Conditioning Industry Co., Ltd., visited Shandong specialized, special and new enterprises and high-tech enterprises rooted in Laishan District, went deep into Land R&D Center, national test platform and production line, and explored our practical achievements in the field of energy conservation, consumption reduction and renewable energy utilization, especially in the research, development and application of heat pump technology.
Zhou Lin, Chairman and General Manager of Yantai Land, reviewed the company's 24 year development history to the press team in the production workshop. He said that at the beginning of his entrepreneurship, the domestic centrifugal compressor technology field faced the dilemma of foreign monopoly and high import equipment prices. Based on this understanding, the company has established the Heat Pump Technology Engineering Technology Research Center and closely cooperated with top research institutes such as Shanghai Jiao Tong University and China Academy of Building Research to embark on the path of core technology breakthrough. Zhou Lin emphasized that adhering to independent innovation is the fundamental way out. The centrifugal compressor independently developed by the company has gone through 7 generations of iterations and finally successfully broken the external technological blockade.
The journalist team then visited the company's national level heat pump unit performance testing platform. The company's technical director Qi Fei introduced that Yantai Land not only undertook three national torch plan projects, but also participated as the main drafting unit in the development of the national standard GB/T25861-2010 "Steam Compression Cycle Water Source High Temperature Heat Pump Unit". In 2015, the company's centrifugal heat pump unit won the "Innovation Special Contribution Award". Qi Fei pointed out that the application scenarios of Land heat pump technology have expanded from building heating to high energy consuming industries such as petroleum, chemical, and electronics, providing stable and efficient process cooling or heating solutions for these industries and achieving independent controllability of key technologies.
In terms of industrial waste heat utilization, Qi Fei explained to reporters the enormous economic and environmental value of Land technology. The efficient heat pump system of Yantai Land can effectively recover waste heat resources such as industrial wastewater, high-temperature flue gas, and compressed air discharged from industrial production, and convert them into high-temperature hot water, which can be reused in process or regional heating. She gave an example to illustrate that applying this technology in a 1 million square meter residential heating project can reduce carbon dioxide emissions by about 50000 tons per year, equivalent to the carbon sequestration benefits generated by planting 280000 trees.
At present, Yantai Land's heat pump technology has been successfully applied in more than 2000 projects across the country, replacing over one million tons of standard coal, and exploring a practical and effective technological path for low-carbon transformation in industrial waste heat recovery and regional clean heating. The company has established a comprehensive technical system for different heat sources and application scenarios, and related projects have been implemented on a large scale in large-scale energy stations in Hebei, Shaanxi, Shandong and other places; A waste heat recovery system developed with precision targeting pain points in the industrial sector has created multiple benchmark projects in industries such as chemical, cogeneration, tire manufacturing, petroleum refining, printing and dyeing textiles. Among them, the solution implemented for a certain petrochemical enterprise achieved significant benefits of saving over 50% of annual operating costs.
Looking ahead, Chairman Zhou Lin stated that as a key infrastructure for energy transformation, the value of heat pump technology is increasingly permeating into all aspects of industrial production and urban life. The mission of Yantai Land is to use continuous technological innovation as the engine, continuously break through in the field of cold and hot energy, and provide solid, reliable, and efficient technical support for this profound energy revolution and low-carbon transformation. Rooted in the innovation fertile land of Laishan, Yantai Land Air Conditioning Industry Co., Ltd. will continue to be driven by technology and led by green development, striving to become a powerful fulcrum for promoting industrial transformation and upgrading and ecological environment protection coordinated development, and work together with partners from all walks of life to contribute greater strength to promoting green, low-carbon, and high-quality development in the region and even the whole country.
