Entering October, my country’s northern cities will soon enter the heating season. On the basis of solving basic heating needs, how to be clean and efficient has once again become a hot spot for the industry.
What are the new concepts and practices in the Nordic countries that have been committed to clean and efficient heating for many years? What are the benefits of new technological methods for improving heating quality? To achieve the goal of 100% renewable energy application by 2050, Denmark’s attempt to North China The heating of the city should have new enlightenment.
 
Optimizing equipment performance can reduce consumption by 30%
 
“Denmark is an energy-poor country with a high degree of external dependence. Once the price of energy products in the international market rises, it will easily lead to energy shortages. For the past 40 years, Denmark has been committed to reducing energy consumption.” Kjelg Stark, President of Danfoss China, told Reporter, "Through years of practice and exploration, the performance of Danish heating equipment has been significantly improved."
 
"For heating in northern China, especially in rural areas, air-source heat pumps are one of the important equipment to improve energy efficiency." Kjelg Stark pointed out that in densely populated cities, pipe networks and other infrastructure are relatively complete, and central heating is more suitable. But in rural areas, "in relatively independent houses, the efficiency of air source heat pumps is obviously higher."
 
According to Kjelg Stark, Danfoss has established cooperation with many Chinese companies. "We provide our partners with the core components of air source heat pumps, such as compressors, heat exchangers, and expansion valves. There are already very good projects in Beijing. By optimizing equipment performance, energy consumption can be reduced by about 30%." In the scenario, Kjelg Stark said that in commercial buildings, by improving the performance of core equipment such as air conditioners, energy consumption will be saved by about 30%. "If it is regionalized central heating, the corresponding project experience shows that the level of consumption reduction will also be 20-30%."
