Abstract
A method and arrangement for drying a water damaged sandwiched floor structure including a top concrete layer, an air permeable isolating layer and a concrete subfloor, comprising providing an air inlet opening and an air outlet opening through the concrete layer, and continuously in a closed loop flowing air through the isolating layer via the openings by a blower and a dehumidifier in serial connection. According to the invention the blower is a suction blower, whereby air is drawn from the outlet opening by the suction blower, and dry air is forced into the inlet opening by the dehumidifier.

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.
An arrangement for drying a water damaged sandwiched floor structure having a top concrete layer, an air permeable isolating layer and a concrete subfloor, the concrete layer having an air inlet opening and an air outlet opening therethrough, said arrangement comprising,
- a suction blower and a sorption dehumidifier in serial connection, and configured for continuously in a closed loop, with substantially no process air escaping to adjoining structures and room environment, to flow air through the isolating layer via the air inlet and air outlet openings,
- wherein the suction blower is configured to draw moist air from the air outlet opening, generate heat to heat the moist air, and provide the heated moist air via a conduit to the sorption dehumidifier for drying the heated moist air,
- wherein the sorption dehumidifier is configured to force the dry air into the air inlet opening.
