The GETS system uses ‘cheap energy’ from the soil and takes this into the barn. The unique combination of optimal heat exchangers, the appliance of a heat pump and the reuse of ventilation air make this system one of a kind. The GETS system enables cooling in the summer and heating in the winter, without any extra energy usage and high costs. The climate in the building improves because more and conditioned air is brought in.
Advantages of geothermal systems
Application of a geothermal system has many advantages. The use of fossil fuels declines and consequently contributes to a healthier environment. Less energy is used leading to lower energy costs. With the GETS system a saving of upto 70% on energy costs can be realized.
At animal level the GETS system also leads to several advantages. The air is brought into the barn conditioned, leading to uniformity in quality and temperature. Animals have a better spread over the area so there is less stress. In buildings with the GETS system, the growth results are better and feed conversion is lower. Since the system also cools in the summer, heat stress is prevented. The overall living and working climate improves.
The GETS system consists of horizontally placed water/air tube heat exchangers. These are placed in the walls of the barn and are connected to a system of tubes placed in the soil. In many cases the air is brought into the building through registervalves to a central corridor and inlets . Through the use of plastic parts the system is resistant to aggressive substances in the air and has a long lifespan. The capacity of the GETS system is adjusted to a percentage of the maximum ventilation and the barn specific circumstances.
The soil system uses the temperature of the earth to cool in the summer and heat during the winter. A heat exchanger in the form of a soil collector is placed in the ground. Liquid, most often water, is pumped in the tube system. This collector is designed per situation and differs per project.
During the winter the water is pumped into the exchanger packages. The fresh intake air is sucked past these same tubes. During this process the heat is exchanged. During the summer the same process takes place, water in the tubes is cooler than the outside temperature, by which the air is cooled.
There are several options for distribution of the intake air. The four meter long exchanger blocks can be placed in the side of the barn. Subsequently the air enters the central corridor before reaching the inlet valves which lead it to the animals. Exchangers blocks can also be placed at the gable end of the house. Optionally in combination with a corridor construction the air is distributed in the length of the barn. In that case the intake air is distributed with register valves.
Cleaning and maintenance
The intake air that passes the tubes is clean, just as the water that runs through it. The completely closed system requires little maintenance. It is advised to have a maintenance check on the system periodically.
The installation of the GETS system includes several processes. Placing the exchanger blocks in the barn the technical room with SKID, the heat pump and regulating equipment and the digging and placing the soil systems.
