VASEN PIPELINE SYSTEMS APPLIED IN THE BEIJING DAXING INTERNATIONAL AIRPORT
01-Jul-2019

Yesterday, the main project of Beijing Daxing International Airport was successfully completed as scheduled, and the focus of work was transferred to the operation!



Daxing Airport is positioned as a “large international hub airport” and is currently the largest open space integrated transportation hub in China. Ranked at the top of the "Seven Wonders of the New World" by the British media, it has achieved a number of world-class, representing the high standards of civil aviation construction in China.

Overlooking from a high altitude, it resembles a phoenix that spreads its wings and is agile.

Daxing Airport adheres to the green concept during construction.

Choose the advanced green air conditioning system - ground source heat pump system,

It is estimated that the annual saving of natural gas is 1,735,900 Nm3.

What is the ground source heat pump system?


——The world's leading green air conditioning system



The ground source heat pump system is the world's most advanced green air conditioning system. The system is a high-efficiency, energy-saving and environment-friendly air-conditioning system that uses underground shallow geothermal resources to provide indoor heating and cooling. It mainly uses shallow geothermal energy as a source of stable heat output.

 

Simply to say, by burying the temperature collecting pipeline in the surface layer, the heat is absorbed from the soil in winter, and the cold is extracted from the soil in summer, and then the ground heat pump unit and the conveying pipeline are used to deliver the cold heat to provide the airport with green and clean renewable energy.

The largest multi-energy complementary ground source heat pump system project in China



According to the calculation, the ground source heat pump system can supply heat and refrigeration for the 2.5 million square meters office space in the public area of Daxing Airport after the official operation. This system is also an important indicator and concrete embodiment of the green construction of Daxing Airport.

 

A total of 2 energy stations were built in the ground source heat pump project of Daxing Airport, and a total of 8 ground source heat pump units were installed. At the same time, in order to increase the energy supply area of the ground source heat pump, Daxing Airport also installed 5 sets of boiler flue gas waste heat recovery heat pump and 1 set of ice storage equipment in No. 1 energy station and No. 2 energy station respectively, increasing the number of equipment during operation. Comprehensive utilization of renewable energy.

Save 17.35.89 million Nm3 of natural gas every year



According to calculations, the Daxing Airport ground source heat pump system can extract 560,600 megajoules (GJ) of shallow geothermal energy every year, and realize the heating and cooling of nearly 2.5 million square meters of office space in the public area of Daxing Airport, saving 1735.89 cubic meters of natural gas, equivalent to 21078. Tons of standard coal can reduce carbon emissions by more than 15,800 tons.

Six major system advantages


In addition to the advantages of high efficiency, energy saving and green environmental protection, the ground source heat pump system can also be used in one machine. The ground source heat pump system can be used for heating and cooling. It can also be used for domestic hot water. It can be used in one machine. One system can replace the two sets of equipment or systems of the original boiler and air conditioner.

 

In addition, the system has the advantages of beautifying buildings, household metering, safety and reliability. The underground heat exchanger is made of high-density polyethylene plastic pipe, which has a designed service life of 50 years and a heat pump unit life of 20 years. The entire system is reliable and low maintenance.



Daxing Airport will be put into operation before September 30 this year.

It is estimated that the annual throughput will exceed 100 million people by 2040.

 

If you wait at Daxing Airport Terminal in the future

You can feel the coolness or warmth of the VASEN pipeline.
