Geothermal system
type of geothermal power technology(for heating and cooling) using constant temperature of groudwater by heat pump.
Geothermal system features
| Vertical closed loop type | StandingColumnWell type |
|---|---|
| - Installation cases | - Small footprint, short construction period |
| - Simple System | - High heat pump efficiency due to direct use of groundwater |
| - Nothing is installed on the ground | - The downtown area is appropriate. |
| - be suitable for cases with a large area | - Systems that resolve existing issues |
| - Reduce system efficiency. | - EGENEngineering's patented technology enables stable operation |
| - MAINTENANCE AVAILABLE |
Comparative data for each type of underground heat exchanger (Cooling capacity: based on 300 USRt)
| Sortation | Vertical closed loop type | StandingColumnWell type | SEN StandingColumnWell type(SEN SCW) |

| overview |  |
 |
 |
| Hole collapse | Degradation due to hole collapse | Use perforated pipe protector to prevent rock collapse and Stable circulation of groundwater | |
| Maintenance | Maintenance required for underwater pumps Supply pipes and recovery pipes of pvc material | Periodic maintenance through flushing operations No deviations by changing the supply pipe and recovery pipe from PVC to HDPE | |
| Efficiency | standard | 105% ~ 110% | |
| features | Improvement of system COP by installing an air & dust separator instead of a heat exchanger to remove foreign substances from pipes EGEN’s SCW type capacity rises when the same area | ||
