1. A method of drying a water damaged sandwiched floor structure having a top concrete layer, an air permeable isolating layer and a concrete subfloor, an air inlet opening and an air outlet opening being provided through the concrete layer, and continuously in a closed loop, the method comprising:
flowing air through the isolating layer via the air inlet and air outlet openings by a suction blower and a sorption dehumidifier in serial connection, with substantially no process air escaping to adjoining structures and room environment,
drawing by the suction blower moist air from the floor structure via the air outlet opening,
generating heat to heat the moist air,
providing the heated moist air into the sorption dehumidifier for drying the heated moist air, and
forcing the dry air into the air inlet opening by the sorption dehumidifier.
