Electric control valve for Changchun to achieve energy saving and emission reduction of about 10%

Energy-saving and emission reduction has become a worldwide topic. In recent days, the Danish Ministry of Foreign Affairs delegation came to Changchun to inspect heating projects and proposed that it will use an electric regulating valve to achieve energy conservation and emission reduction for Changchun by about 10%, which is to improve air quality in Changchun City. There will be great help.

The Danish Government Ministry of Foreign Affairs' International Development Assistance Agency (DANIDA) and China’s government government loan program began in 1994. The loan is dedicated to helping China in basic heating, sewage treatment, waste incineration, education, medical and small-scale industrial projects. The construction of the field. Since 1994, China has used the Danish government's total loans of about 2 billion yuan to build more than 50 projects and achieved good economic and social benefits.

The heating network project of the Yutan Central Heating Project in Changchun City utilizes a Danish government loan of 10 million euros. It is mainly used for the purchase of heat source plant circulating pumps and Danfoss frequency converters, Danfoss heat exchanger units, thermal network control systems, geographic information systems, and thermal network simulation systems. , Thermal net strength design software, automatic water treatment equipment, thermal network prefabricated insulation pipe, electric control valve system and related components and other equipment. The project was jointly completed by Danish companies led by Danfoss. Danfoss, as the general contractor, provides core equipment and technology for the thermal network project of the Changchun Yutan District Heating Project, responsible for the delivery of the goods of the project, and is responsible for the overall commissioning and service of the equipment. Danfoss, a global leader in centralized heating, has implemented 14 such centralized heating projects in China.

The heat network project of the Changchun Yutan Central Heating Project has achieved a centralized heating area of ​​nearly 6.5 million square meters. The Danfoss heat exchanger unit used in the heat network project automatically adjusts the electric control valve by detecting the temperature and outdoor temperature of the secondary network. The opening degree enables the heat supply of the heating station to be automatically adjusted. The Danfoss frequency converters installed in the heat source plant and the heat exchanger unit circulation pump have greater energy-saving effect.

Danfoss has long been committed to the development in China and is committed to using electric control valves to increase energy efficiency and contribute to the sustainable development of the Chinese economy. The Changchun Yutan Concentration Heating Network Project replaced the former high-energy small boilers in the area, which will reduce 34,872 tons of dust emissions and reduce 1,022 tons of sulfur dioxide emissions per year in Changchun City. This will reduce CO2 emissions by 75,000 annually. Tons, a reduction of 10% for the city, will improve the environment and air quality in Changchun City, and will contribute to long-term energy conservation and emission reduction.
