<p>The closed-loop geothermal probe (1) comprises: a tubular element (9) which can be buried in a water-bearing stratum (10) containing stratum water (11), in which inside the tubular element (9) is delimited a housing space (14, 15) for housing a heat exchanger (17) in which flows an operating fluid (8) suitable for exchanging heat with the stratum water (11), and in which the tubular element (9) comprises a first access opening (20) and a second access opening (21) for the flow of the stratum water (11) between the water-bearing stratum (10) and the tubular element (9), a pumping device (22) for pumping the stratum water (11) housed inside the tubular element (9) and suitable for returning the stratum water (11) in inlet from one of the access openings (20, 21) and for pumping it in exit through the other access openings (20, 21), filtering means associated with at least one between the first access opening (20) and the second access opening (21), and at least a utility pipe (25) suitable for cleaning the filtering means.</p> |
