Lotte Tower, Seoul, Korea
 |
Installation Date: |
| 2009-2010 (Currently Under Construction) | |
| Project Size: | |
| 24,000 kW - primary closed loop system 10,000 kW – municipal geothermal 14,000 kW. | |
| Geothermal Configuration: | |
Closed loop & Municipal Water |
|
| Annual Energy Savings Estimated: | |
| 57％ |
Project Scope: Due to the limited land space in this city center location, there were 2 different types of geothermal heating and cooling systems installed. This first phase geothermal system is a closed loop system using vertical bore holes. The second phase is geothermal heat pumps served by the municipal water system. Under an agreement between K-Water the government owned water distribution system for all of Korea and Lotte Construction, the city will allow heat energy to be either extracted in the winter and rejected in the summer. A new 80cm water pipe line was installed to serve the municipal water. The municipal water passes through a plate and frame heat exchanger before being re-injected into the municipal water system.
Qingdao Media Center, Qingdao, China
 |
Installation Date: |
| 2006 | |
| Project Size: | |
| 2600 kW | |
| Geothermal Configuration: | |
Surface Water – Sea Water System |
|
| Annual Energy Savings Estimated: | |
| 51% |
Project Scope: The media center at Qingdao faced a large challenge. How to install a geothermal heat pump system when there is no land area for drilling vertical bore holes. The solution was to use the surface water from the sea located near the building. Water is pumped from the sea and circulated through plate and frame heat exchangers, the energy is then used to supply both heating and cooling provided by the heat pumps located inside the building.
Art Farm Greenhouse, Busan, South Korea
 |
Installation Date: |
| 2009 | |
| Project Size: | |
| 2100 kW - primary closed loop system | |
| Geothermal Configuration: | |
Closed Loop – Vertical bore holes 35,000 meters – 200 meter depth |
|
| Annual Energy Savings Estimated: | |
| 70% |
Project Scope:Replace an oil fired boiler system and traditional air conditioning system. Provide geothermal heating in winter and cooling in summer to maintain temperature inside the glass greenhouse above 17C winter and less than 30C in summer. Maintaining temperature parameters allows up to 100% more production for the vegetables and they are higher quality with better nutritional value.
