Heating and cooling "one shoulder", ground source heat pump technology helps Beijing Green Winter Olympics

Green Olympics is one of the four concepts of "green, shared, open and clean" for the 2022 Beijing Winter Olympics. In the process of hosting the Olympics, the concept of "Green Winter Olympics" has become increasingly popular among the people, and batches of "Green Winter Olympics" achievements have come as promised, and green is becoming the brightest background color of the Beijing Winter Olympics.

The ground source heat pump + energy storage integrated energy utilization project of Yanqing Comprehensive Transportation Service Center, which was officially put into operation on the 100-day countdown to the Winter Olympics, has been running for more than two months.

Let's go to Yanqing Comprehensive Transportation Service Center and experience the clean heating here.

The Yanqing Comprehensive Transportation Service Center has a total construction area of ​​116,900 square meters, of which the heat pump energy supply area is 78,500 square meters. 100% of it adopts the "ground source heat pump + water storage" clean and renewable technology, and the construction is supported by the municipal financial funds. Not only can it fully meet the winter heating needs of the transportation service center, but also the "responsibility" of cooling in the hot summer.

This environmental protection system is equipped with "complete" configuration, including 977 soil heat exchange holes under the drilling foundation, and a 1,600-cubic-meter water energy storage system. A number of green and energy-saving advanced technologies, through the "Internet +" intelligent management platform technology, the ground source well, energy center, and terminal equipment are operated as an organic whole. Stable working and operating environment.

It is worth mentioning that the entire system of the project does not consume gas throughout the year, realizing 100% renewable energy application. According to estimates, it can save an average of 658 tons of standard coal and 1,723 tons of carbon dioxide emissions every year, practicing the concept of green Olympics.

In addition, on the Beijing section of the Beijing-Li Expressway, the starting point management office, the Guishuihe tunnel management office, the Banquan service area, and the mountain tunnel management office, four supporting service areas for the Winter Olympics, all adopt the coupled heating technology of ground source heat pump and air source heat pump Heating, with a total area of ​​23,700 square meters. Among them, the starting point management office installed 232 buried holes with a depth of 100 meters, 2 ground source heat pump hosts, 2 air source heat pump units and other ground source heat pump systems; Guishuihe Tunnel Management Institute installed 36 holes with a depth of 100 meters underground hole drilling, 1 ground source heat pump host, 1 air source heat pump unit and other ground source heat pump systems; Banquan service area installed 96 buried holes with a depth of 100 meters, 2 ground source heat pump hosts, 2 Ground source heat pump systems such as one air source heat pump unit; 74 underground drilling holes with a depth of 100 meters, 2 ground source heat pump units, 2 air source heat pump units and other ground source heat pump systems installed in the Mountain Tunnel Management Office.

It is understood that all new venues for the Beijing Winter Olympics and Paralympic Games adopt high-standard green design and construction technology, and adhere to the principles of "building energy saving, building land saving, building water saving, building material saving, and protecting the environment" in the construction of the venues. , all new venues have obtained the Samsung green building design logo. Among them, in the construction of the Winter Olympics venues, the first large-scale use of carbon dioxide environment-friendly refrigerants for ice making, carbon emissions approaching zero, not only reduces the damage to the ozone layer caused by traditional refrigerants, but also generates a large amount of high-quality waste heat during the refrigeration process. Recycling and reuse, the efficiency is increased by 30% compared with the traditional method.
