The solution with geothermal horizontal probes requires less initial investment than the solution with vertical development due to the lack of charges against perforazione.Di is a less efficient because the more superficial layers of the soil most affected by changes in the weather outside.
Are required surfaces of land very ampie up to two times the surface area to be air conditioned.
In this case we speak of horizontal collectors made of polyethylene pipes or cross-linked polyethylene inlta pressure: the solution in polyethylene requires a bed of sand for the housing of the tubes while in the case of crosslinked polyethylene pipes can withstand the stresses of stones or other bodies present in the soil.
Experimental investigations and practices of good practice have helped to define a standard depth to which pose manifolds: the maximum depth of the excavation is between 2 3 and m so that even the seasonal variations in temperature appear to be attenuated.
Annual (° C)
The thermal influence of the horizontal manifold on the ground is greater on the extension of the collector: it is recommended that the surface of soil to be affected only by vegetation with shallow root system so as not to be affected by temperature variations due to the presence of the implant.
