Ground source heat pump and other renewable energy warm 211 project

According to estimates by experts, the low-temperature energy that can be collected in China's soil that is nearly 100 meters deep is about 1500 times that of China's current power generation capacity of 1 billion kilowatts, and the low-temperature energy that can be collected every 100 meters within a year is also 200 million kilowatts. It is calculated that the reserves of 2,000 square kilometers of shallow geothermal energy in the Beijing Planning District are equivalent to 107 million tons of standard coal. If you look beyond the country, the number will obviously become even greater. It is reported that in recent years, Binzhou City has expanded the scope of the “211 Project” pilot to all counties. Before the advent of winter, more rural teachers and students will have hot meals, hot water, and heating and sanitation. WC.

The “211 Project” in rural primary and secondary schools is also called the “two hot and one warm” project. “Two hot” refers to the allocation of tea stoves, insulated barrels, steamers, and steamers to rural primary and secondary schools to solve drinking water and eating in rural primary and middle school students. The problem of hot rice; "a warm" refers to the provision of boilers or heaters for rural primary and secondary schools to solve the problem of winter heating; "change" refers to the promotion of the use of biogas and other technologies to improve pollution control and provide cleanliness to rural primary and secondary schools. energy.

Shandong Province implemented pilot projects for rural primary and secondary schools “211 Projects” in 5 cities. Yangxin and Zouping became the first pilot counties in the province. The "211 Project" pilot invested a total of more than 10 million yuan, completed the construction of a 32,000-square-meter school building heating project, reconstructed 2,600 square meters of toilets (including greenhouses), built 568 new toilets, built 740 cubic meters of biogas digesters, and yielded nearly 2 students. Ten thousand people. The “two hot and one warm” pilots adopted the “heat pump of geothermal pump heating radiator”, “ground source heat pump heating fan coil cooling (cooling)”, “solar power, and electric heating as auxiliary heating radiator cooling "," "Solar-based, ground-source heat pump for auxiliary heating fan coil cooling" four different modes of heat supply and cooling. Yangxin County Silver High School adopts the "ground source heat pump fan coil heat dissipation" model, which costs about 12 yuan per square meter for heating in winter. The “re-toilet” pilot adopted a unified “ecological toilet biogas digester canteen renovation” model.

It is understood that apart from the inclusion of Yangxin's two schools in the provincial pilot, Huimin, Zouping, Wuxi, Zhanhua, Boxing, Bincheng and Binzhou Economic Development Zone each have a school at the municipal pilot level. In addition to the above-mentioned several types of heat-dissipating modes for the pilot, a variety of new energy heating methods, such as the straw particle semi-gasification combustion heat source model, will be adopted one after another.
