- This technology utilizes water overflow in several geothermal heat exchanger to collect groundwater into a single water tank, enabling geothermal cooling and heating using a single circulation pump.
* When returning from a heat pump to a geothermal heat exchanger, the ground layer, the coefficient of pitcher, and the quantity of groundwater are different, which increases the amount of injection in some plants, and the principle of collecting groundwater flow to the surface is applied to the collection tank, so it can be used for large-scale energy needs in building and smart farms etc.

 - This technology installs a collection tank that collects groundwater as circulation water, connects it to a heat pump by a horizontal pipe, and sends heat-switched circulating water from a heat pump to several geothermal well, and returns to the collection tank after exchanging heat with the ground due to water overflow of groundwater.
* 4 to 5 geothermal pipes per collection point are the basic connections
- The biggest difference from the existing open loop system is not to install the underwater motor pump in the geothermal heat exchanger, but to reverse the natural overflow of circulating water (ground water) exchanged in the geothermal well.
* Existing open loop (SCW) geothermal heat exchanger depth is approximately 500m, but this technology can freely change geothermal power depending on heat capacity.
- As the groundwater motor pump, which was previously installed in each geothermal system, does not need to be used for technical purposes, installation cost, operation power cost, and maintenance cost are reduced by more than 15% compared to the previous one.

○ Overview of products
- Product Name (Production): Geosum Hybrid
- Effectiveness and Effect: It can be applied to smart farms, flower complexes, collective residential areas, and new new new city energy fields that require large-scale heating and cooling capacity. It can increase efficiency and reduce maintenance costs by reconstructing existing technologies. By applying this technology, grpimdwater overflow phenomenon, which used to be an open disadvantage, is advantageous to use groundwater as circulating water, and the heat capacity per space is significantly reduced compared to the existing vertical density.
