Apparatus for drying a water damaged floor structure

A drying apparatus for a water damaged floor structure having an intermediate layer between a surface layer and a subfloor, the drying apparatus comprising

• a suction blower for drawing, from an outlet opening in the floor structure, moist process air from the intermediate layer and for heating the moist process air;
• a sorption dehumidifier having a fan and a sorption block of a rotating type and adapted to divide the process air into a dry air flow and a wet air flow;
• the fan of the sorption dehumidifier having an inlet for process air from an environment and being arranged between the suction blower and the sorption block;
• a PTC element arranged in a regeneration chamber in the sorption dehumidifier for the sorption block in the sorption dehumidifier;
• and
• a common housing for the suction blower and the sorption dehumidifier;
• wherein
• the sorption dehumidifier is arranged to receive the heated moist process air from the suction blower mixed with the process air from the environment and divide the thus mixed process air into the dry air flow and the wet air flow;
• the dry air flow is arranged to be forced down to the intermediate layer through an inlet opening separate from the outlet opening in the floor structure where the dry air flow accumulates moisture from the floor structure and is converted into new process air which is again drawn and heated by the suction blower in a closed process;
• and
• a sound and heat insulation in the housing.
