    As the saying goes, northerners rely on heating in winter, southerners rely on a healthy atmosphere in winter.

    It seems that the temperature in the south is not cold compared to the temperature in the north, but in fact, the cold in the south is deep in the bone marrow, especially the wet and cold environment. From the perspective of meteorology, humidity has a great impact on the perceived temperature, every 10% increase in humidity, the temperature felt by the human body will be reduced by 1 ° C, that is to say, in the cold and wet south, the temperature felt by the human body is much lower than the actual temperature. Because there is no public heating, winter in the south is actually worse than in the north.

    Affected by extreme weather, the northern provinces have begun to test the heating water to prepare for heating, while living in the south, the winter basically depends on air conditioning, wall hanging stove and small sun. This kind of household division not only wastes resources, is not conducive to energy saving and emission reduction, increases the economic burden of the people, but also has security risks. Therefore, in recent years, the call for heating in the south has become increasingly strong.

    Here are some suggestions from NPC deputies at the two sessions:

We will move heating lines southward and accelerate the development of geothermal energy

    Wu Yongli, deputy to the National People's Congress, Chairman of Fuyang Municipal Committee of MINjian, Chief Engineer of Fuyang Economic and Technological Development Zone Management Committee:

    We will move heating lines southward, accelerate the development of geothermal energy, and create a livable environment for the people.

    Shallow geothermal energy is a kind of green, low-carbon and recyclable renewable energy. Wu Yongli pointed out that accelerating the development and utilization of shallow geothermal energy is not only of great significance for ensuring energy security, adjusting energy structure, energy conservation and emission reduction, and improving the environment, but also has a significant pulling effect on cultivating emerging industries, promoting new urbanization construction, and increasing employment.

    Wu Yongli proposed that a new geothermal + smart energy research center be built to increase the introduction and research of shallow geothermal energy core technologies. At the same time, the provincial geothermal energy information monitoring center has been built to implement status monitoring, accurate measurement and intelligent control of the whole process of geothermal energy collection, transformation and utilization, so as to realize energy digitalization and energy consumption visualization. Establish a systematic and regional research platform for shallow geothermal energy.

At present, the south is more suitable for local centralized and distributed heating

    Zhang Jie, Deputy to the National People's Congress and deputy manager of the official Maintenance Department of the Operation three companies of Chongqing Rail Transit (Group) Co., LTD. :

    In recent years, the trend of snow and ice moving southward is obvious, and the lowest temperature in the Yangtze River basin in winter has reached minus 8℃ to 10℃. In addition, there is more rain in the southern region, and the humidity has a greater impact on the cold and warm feeling of the human body. Every 10% increase in humidity in winter, the temperature felt by the human body will decrease by 1℃.

    "The southern part of China is currently more suitable for local centralized and distributed heating." Zhang Jie said that at present, the south of China generally uses air conditioning, oven, radiator, central air conditioning and other heating equipment to spend the winter, this way not only wastes power resources, is not conducive to energy saving and emission reduction, but also has certain security risks; In addition, in order to enhance the ability of heat insulation, ventilation, moisture and so on, most buildings in southern China use open balconies and large bay Windows, and the thermal insulation effect of buildings is relatively poor, and the heat dissipation of winter houses is fast.

    For the use of local centralized and distributed heating in southern cities, Zhang Jie put forward several suggestions:

    On the one hand, the Ministry of Housing and Urban-Rural Development led the revision of the "Code for Thermal Design of Civil Buildings" to improve the thermal insulation standards of civil buildings in the southern region, from the planning of the community, household design, housing construction and building materials selection, to meet the needs of summer insulation while taking into account the requirements of winter heating and thermal insulation. "The renovation of external wall insulation facilities of old housing should also be included in the unified planning and design."

    At the same time, the use of local materials and clean energy to solve the heating source problem. The use of local clean energy to provide heat sources for heating in southern cities and towns can not only save transportation and storage costs, but also provide high cost clean heating for southern cities and towns.

    Finally, we will promote the construction of clean and low-carbon heating demonstration projects in the South. First, start clean and low-carbon heating pilot demonstration projects; The second is to launch a special project to develop clean and low-carbon heating technology. It is suggested that the Ministry of Finance, the Ministry of Science and Technology, the Ministry of Education, and the National Natural Science Foundation jointly establish an expert evaluation group to draw up a list of special technological breakthroughs in clean and low-carbon heating in the South, and set up a special fund for scientific research on clean and low-carbon heating in the South. Third, we will encourage local innovation.

    In recent years, a number of heating enterprises in China have begun to actively explore smart heating, including Huawei, Ali and other Internet technology companies have also entered the bureau. With the development of science and technology, the future of southern heating "tricks" will be more. In the future, energy-saving and cost-effective heating equipment will be the "mainstream" of the southern heating market. Now the southern collective heating is still in the planning, preparation, some southern areas have been first tested. I hope that environmental protection, energy saving and cost-effective central heating can be popularized in the cold and wet southern areas as soon as possible, and I believe that it will also bring a new round of development opportunities for the HVAC industry.
