1 Please provide a short description of the state-of-the-art and/or current trends in the field? How does the result fit into it?
Heating of greenhouse with the use of geothermal energy constitutes a reliable solution for many years. The required technology is not found in phase of growth but is completely developed and required materials are located easily in the relative market. In the concrete project what is sought it is how much a geothermal application of shallow depth it is possible to cover the needs and moreover if the interventions in the surface of the ground influence it’s thermal behavior (at those depths). Geothermal pump systems exchange thermal energy between a greenhouse and the ground. When the green house needs heating, the system extracts heat energy from the ground, and pumps it into the building where it is boosted by the heat pump to a comfortably warm temperature. Conversely, when the green house needs cooling, the heat from the green house is collected by the heat pumps and sent into the ground, much as a refrigerator’s compressor transfers heat from inside the refrigerator to the outside. This exchange of thermal energy makes the system efficient. Rather than creating heat by burning a fuel on site, or chilled water by rejecting heat to the hot summer air, the geothermal heat pump system moves thermal energy between the ground and the greenhouse using heat pump technology.                                Other applications of the geothermal heating systems, either shallow or deep, are the heating and cooling of animal houses (i.e. farrowing houses, poultries etc) as well as to provide moderate heat to the green crop dries.  

 

2 What is the problem/need/knowledge gap that the research result is responding to?  How was it addressed before?
Further research can take place at two levels:

  • Improvement of the ground’s thermal ability with different methods and
  • observation of the phenomena which are taking place in the greenhouse (air movements, temperature distribution etc).
  • the animal behavior within geothermally heated and cooled constructions.
  • The efficiency of geothermal driers. 

 

 

3 What is the potential for further research?
The overall efficiency of the ground thermal heating must be case by case examined. Additionally, geothermal electric plants have until recently been built exclusively where high temperature geothermal resources are available near the surface. The development of binary cycle power plants and improvements in drilling and extraction technology may enable enhanced geothermal systems over a much greater geographical range.

 

4 What is the proposed method of IPR-protection? (patent, license, trademark etc.)
The proposed IPR protection method is industrial design from the Greek Patent Office (OVI).

An industrial design renders an object attractive or appealing, thus increasing its marketability and adding to its commercial value. The design may be three-dimensional based on the shape or surface of the object, or two-dimensional based on the object’s patterns, lines or colours. Novelty, originality and visual appeal are essential if an industrial design is to be patented

 

5 What are the steps that need to be taken in order to secure the IPR-protection? What is the cost of IPR-protection?
The steps are:

  • Design of the application file to OVI for industrial design.
  • Application to OVI.

An industrial design application is required to complement the patented ground heating design for green houses. The cost of industrial application IPR to OVI : application cost 500 euro file preparation cost: 1500 euro

 

6 What is you overall assessment of the scientific maturity of the research result?
The technology is scientifically matured and is at the stage where efficiency improvements could be made related to the use of appropriate heating loops (closed or open loops). Additionally, the thermal efficiency of geothermal electric plants is low, around 10-23, because geothermal fluids are at a low temperature compared to steam from boilers. By the laws of thermodynamics this low temperature limits the efficiency of heat engines in extracting useful energy during the generation of electricity. Exhaust heat is wasted, unless it can be used directly and locally, for example in greenhouses, timber mills, and district heating etc. The efficiency of the system does not affect operational costs as it would for a coal or other fossil fuel plant, but it does factor into the viability of the plant. In order to produce more energy than the pumps consume, electricity generation requires high  enthalpy geothermal fields and specialized heat cycles.
