1. Energy-saving principle of ground source heat pump
Ground source heat pumps use the stable temperature of the underground thermostatic layer (usually 10-20°C) to convert geothermal energy into heat or cold energy that can be used by the building through a heat exchanger. Its energy-saving principle is mainly reflected in the following aspects:
| Energy saving factors | Specific instructions |
|---|---|
| Efficient heat exchange | The underground temperature is stable, and the heat pump system does not require additional energy consumption to adjust the temperature. |
| low running costs | Compared with traditional air conditioners, energy consumption is reduced by 30%-70% |
| Renewable energy utilization | Directly utilize geothermal energy to reduce dependence on fossil fuels |
2. Energy-saving advantages of ground source heat pumps
According to recent industry data and user feedback, ground source heat pumps have outstanding performance in energy saving. The following are its main advantages:
| Advantages | Data comparison |
|---|---|
| High energy efficiency ratio (COP) | The COP of traditional air conditioners is 2-3, while the COP of ground source heat pumps can reach 4-6 |
| Long term energy saving benefits | The initial investment cost can be recovered within 5-7 years of use |
| Environmental protection and emission reduction | Each ground source heat pump reduces CO₂ emissions by approximately 3-5 tons per year. |
3. Practical application cases of ground source heat pumps
Recently, many successful application cases of ground source heat pumps have been reported. The following are some typical cases:
