The average altitude of Naqu city is more than 4500 meters, and the coldest time can reach minus 30℃. It is another winter, but this winter in Naqu City is exceptionally warm. With the deepening of the grass-roots heating work in high-altitude areas, from cities to villages, from schools to hospitals, the frigid north of Tibet is filled with a thick warmth.
Came to Nyima Township, Nyirong County, Tonglong Village, the central home, photovoltaic heating radiator placed in the middle of the bedroom, a steady stream of heat. Due to the change in the heating method, the secondary center also changed the hidden bed in the bedroom to a double bed. "After photovoltaic heating, our villagers have achieved zero cost heating, which is both warm and affordable."
In July 2023, Nyima Township carried out the "zero carbon" beautiful village construction project, which adopts the operation mode of "photovoltaic + heating" to realize the self-use of power for the herdsmen and form a green and low-carbon circular development.
The application of new technologies continues to improve the production and life of the masses, and a winter water supply security technology in Shanghai is helping tap water in high-cold areas to "one-click". At present, the technology pilot project has been in normal operation in 16 households in Serni District of Naqu City, which is 4500 meters above sea level and has an average of minus 16 ° C, and the water difficulties of the masses in winter have been effectively alleviated. It is understood that the technology does not require electric heating wire, does not need water pipe insulation layer, through automatic control technology to achieve water pipe antifreeze, than the traditional heating and insulation technology saves 95% of energy consumption.
From cow dung fires to photovoltaic power, rural heating is revolutionizing. Then to the campus where the children study and live, the flowers and trees in the warm corridor add a different color to campus life.
Walking into the National Energy Group Hope Primary School in Nyarong County, more than 4,700 meters above sea level, the flowers and trees in the glass warming gallery are flourishing. "It's cold outside, but inside, we can wear light clothes to study and do activities in the warming gallery or classroom." Student Tsering Tashi said. In 2021, the National Energy Group invested 7.25 million yuan to build the first pressurized oxygen membrane arena in the Tibet Autonomous Region's education system, effectively alleviating the problem of hypoxia for children exercising at the plateau; An investment of 8 million yuan was invested to build the sunshine warm shed project, which effectively solved the problem that children had nowhere to go for recess activities when there was strong wind and low temperature weather on the winter plateau.
The construction of high altitude school heating project in Naqu City has steadily advanced, and since this year, more than 206 million yuan has been allocated to 191 schools above 4500 meters above sea level in the city to implement solar heating and heating gallery projects. Up to now, the solar + energy storage electric heater project has been completed and put into use; Solar + electric assistance, solar + air energy heat pump and heating gallery projects have been completed and entered trial operation; The equipment procurement of the solar + electric dispersion project has been completed, and the renovation work is progressing in an orderly manner.
The central heating work in Naqu City this year began on October 15, has reached 2.4 million square meters of heating area, the average water supply temperature of the primary network is about 90 ° C, the average return water temperature is about 70 ° C, the average water supply temperature of the secondary network is about 60 ° C, the average return water temperature is about 50 ° C, the overall heating effect is good.
2023 to 2024 annual heating season has arrived, in recent days, Naqu City heat source factory in advance deployment, early mapping, forward service, solid and meticulous winter heating work, to ensure that the heating on schedule, so that the masses warm more warm heart.
According to the overall layout of smart ecological boutique city construction, in order to promote the development of clean energy heating, Naqu City heat source Factory actively promotes the development of clean energy, and currently reached an agreement with Xizang Jinhang Company to develop geothermal heating, which can solve the heating demand of 800,000 square meters at the end of November. At the same time, in cooperation with Jiangsu Shengshi Energy Saving Company, the use of ground source heat pump technology can achieve 800,000 square meters of heating coverage within the year.
In the next step, Naqu City will give full play to the advantages of geothermal and ground source heat pump "zero emission, zero pollution and low cost", further develop geothermal in 2024, promote ground source heat pump technology, expand the geothermal coverage area of 1.2 million square meters before September 2024, and phase out existing coal-fired boilers to achieve low-carbon development.
New energy, new technology and new equipment make the heating in northern Tibet greener and more environmentally friendly, and also make the life of people of all ethnic groups in northern Tibet warmer and more comfortable.（Source: China Xizang Website）
