Abstract: Heating is the biggest problem in people's livelihood in the society. It coldly tests the government's administrative capabilities. For urban fringe areas and rural areas, even with the installation of urban heating pipe networks, the energy loss caused by the heating distance is quite large. So, how to explore a "low carbon era" heating mode? Committee member Liu Chuntang suggested using a ground-source heat pump to recycle the use of relatively constant-temperature groundwater, a "green air conditioner," for heating, in order to achieve energy conservation and emission reductions.
Investigation: The heat loss of the heating pipeline is serious and the heat loss is serious, causing waste. Liu Chuntang told reporters that the most heated problems are those old houses where small boilers are heated. “There are many problems with these old house corridors, and there is a serious heat loss in the heating pipes.†Liu Chuntang found out through investigation that the corridors of abandoned communities and old houses were abandoned. Some windows are incomplete, some are wood corridor doors, and some do not even have corridor doors. As many heating pipes are exposed outside, resulting in heat has not yet entered the residents' homes, they have lost a large part of the corridor.
Advantages: Geothermal heating without pollution "This 'ground heat' is actually a ground source heat pump heating." Liu Chuntang said that the ground source heat pump is an efficient and energy-saving air-conditioning system that utilizes shallow underground geothermal resources, which are both hot and cold. Can be widely used in commercial buildings, public buildings, residential apartments, schools, hospitals and other buildings. One of the benefits of "geothermal" heating is environmental protection. There is no emission of nitrogen oxides, sulfur dioxide and smoke, and no pollution. At present, "geothermal" heating has been tried in Beijing and other places with good results.
Current situation: Geothermal development is not ideal in rural areas “Ground source heat pump technology has been recognized by more and more people because of its advantages of environmental protection, energy saving and clean, and simple control equipment. But in fact, the development of ground source heat pump technology in rural areas in China is very Not ideal.†Liu Chuntang said that the energy consumption of rural households in our city has basically completed the transformation from primary energy to commodity energy.
Liu Chuntang found in the survey that rural households around Beijing averaged 2.9 tons of coal, 920 kWh of electricity, and 3 to 4 cans of liquefied gas. In the total household energy consumption, coal accounts for 74%, electricity accounts for 13%, liquefied gas accounts for 8%, and straw and other biomass energy accounts for only 5%. The energy consumption of 2.9 tons of coal used by rural households for heating is 2.3 tons, which is close to 80%. According to calorie conversion, about 60% of household energy consumption is used for heating in winter, and 78% of households believe that heating burden is heavy. The energy consumption situation in rural areas around Dalian is basically the same as in Beijing.
In view of the problems encountered in the promotion of geothermal heat in rural areas, Liu Chuntang said that the primary investment in ground source heat pump systems is relatively high, and the single square meter construction cost for single-unit residential buildings is usually around 350 to 400 yuan. The cost of rice is usually around 150-200 yuan, resulting in a situation in which rural residents cannot use it. At the same time, the insulation measures of rural buildings are generally not good, resulting in large heat losses, which in turn cause high heating loads and high operating costs. In addition, because water and ground source heat pump systems are mostly used in public buildings, professional technicians are involved in the use of the system. When ordinary families use them, especially when they are used by rural households, it will inevitably cause operational mistakes, and in severe cases it will lead to system damage.
Suggestion: Granting subsidies to residents according to heating area Liu Chuntang told reporters that in order to solve problems, it is necessary to set up a professional organization or to instruct professional departments to carry out unified planning and research on the implementation of geo-energy technologies in the rural and urban areas of the city and come up with an implementation plan and plan. And policy. Or take out certain areas and land plots to demonstrate; for the development units that use energy and new energy technologies in urban edge development projects or rural homestead renovation projects, give preferential treatment in terms of land price and supporting facilities; at the same time, residents’ heating costs are not Change; For rural households using ground-source heat pumps in rural houses and greenhouses in rural areas of our city, a certain amount of subsidies will be given according to the amount of investment or the area of ​​heat supply according to the policy of home appliances to the countryside.
In addition, since most of the time for heating use by rural users is at night, it is hoped that the relevant government departments will consider introducing the same peak-to-valley tariff policy for rural users as for urban users. In addition, the design, distribution and construction units of the energy and new energy technologies in the implementation areas shall be given corresponding preferential and encouraging policies.
