- Efficient energy-saving and eco-friendly air-conditioning system
- Adopting underground superficial layer geothermal resources to heat and cool
- Can achieve energy transfer from low to high temperature heat source by inputting less high-grade energy (electric energy)
- In winter, it draws heat of soil for indoor heating after temperature rise
- In summer, it draws indoor heat and releases it to soil
- Ensuring balance of underground temperature throughout year
