The traditional end set temperature control electric valve way

At present, energy shortage has become a serious problem that restricts China's economic and social development. Building energy conservation, as an important part of the national energy strategy, has drawn more and more attention. At present, China's urban civil buildings consume about 23% of the total electricity generated in China. The impact of building energy consumption on the development of national economy and people's normal working life has become increasingly prominent. China has nearly 500 million square meters of large public buildings using central air conditioning. According to a survey of the energy consumption of nearly 100 large public buildings in Beijing, Shanghai, Guangzhou and Shenzhen, they found that their electricity consumption per unit area is 10 to 20 times that of the average residential building in the city, and more than half of the electricity consumption is for Central air conditioning. The total construction area of ​​less than 5% of China's urban civil construction area of ​​large public buildings, the electricity consumption accounts for about 25% of China's construction electricity consumption. Moreover, with the development of our economy and the acceleration of urbanization, large-scale public buildings are growing rapidly at a rate of 3,000 to 40 million square meters per year. The proportion of large-scale public buildings with high energy consumption in the total urban construction area is also growing , Resulting in the growth rate of construction electricity consumption is higher than the growth rate of the total construction. Therefore, the key technologies to reduce the energy consumption of large-scale public buildings air-conditioning system can not only lead the energy-saving design of HVAC in public buildings in China, promote the research and development of new energy-saving air conditioning products and the formation of the corresponding product industrialization, reduce the level of building energy consumption Actively promote and promote the role; the same time, the research results in the form of demonstration projects to promote, for building energy efficiency and even the country's energy strategy, has a very important significance.
