Why monitor the parameters over time?
Monitor the parameters over time through direct measurements and numerical simulation allows assessing the performance of horizontal collector systems.
The ideas consists on using data collected on field to simulate the thermal interference between horizontal heat exchangers and subsoil. Accordingly, we want to evaluate the influence of TEBM on new promising technological solutions as helix systems.
First of all, for each soil mixtures used in situ, we collect monthly thermal conductivity, moisture content and electrical resistivity data. Then, we determine later in laboratory bulk density and moisture content on duly collected samples. Finally, we acquire daily data from the climate control unit and from the helix systems. The former, gives us information related to the atmospheric condition through the year. Instead the latter provides ground temperature information inside/outside the helix and the forward/return fluid velocities of the helix in operating conditions.
Consequently, combining all these data, the research will focus also on the long term environmental impact of the entire system.
