Description
- This invention relates to an apparatus for drying a water damaged floor structure, comprising a suction blower for drawing process air from the floor structure, a sorption dehumidifier for receiving the process air from the suction blower mixed with process air from the environment through an inlet and converting the thus mixed process air to dry air, a common housing for the suction blower and the sorption dehumidifier, and a PTC element arranged in a regeneration chamber in the sorption dehumidifier for a rotating type sorption block in the sorption dehumidifier.
- A general drying apparatus of this kind is known from SE 1450924. However, this drying device is not stated to be particularly intended for drawing wet process air from a floor structure.
- An object of the invention is to provide an apparatus of the above identified kind that is particularly adapted to effectively dry a floor structure by providing a high vacuum and energy efficiently converting the humid process air into hot dry air which in various applications can be returned to the floor structure, either directly through dry air flow or indirectly through heat transfer, depending on application.
- Another object is to provide an optimized integrated drying machine which is easy to handle, transport and install, has a low noise and is energy efficient.
- According to the invention, the suction blower is a side channel blower capable of heating the process air, an additional fan being arranged between the suction blower and the sorption dehumidifier to increase the flow of the mixed process air from the suction blower and the surrounding environment, and the housing has a sound and heat insulation. The side channel blower has an inherently high ability to generate high suction power and to heat the humid process air. The additional blower is capable of increasing the flow of the pressurized heated humid process air entering the dehumidifier. The presence of the PTC element in the dehumidifier enables continuous dehumidification at high temperatures without activating a protective device against overheating, which is not the case with traditional pipe dehumidifiers. As a result, the drying device also becomes more or less self-regulating, so that it can work safer without supervision. Thus, the PTC element is crucial for the proper operation of the device.
- The energy efficiency is achieved by the fact that a large part of the heat which is otherwise emitted to the environment from the suction blower including its motor and suction and pressure lines can be suitably delivered to the dehumidifier inside the heat insulated housing where it is reused by the dehumidifier. The suction blower provides the greater part of the process air flow through the intermediate layer and therefore needs high power which generates high heat. This is advantageous and of great importance for this type of drying operation, where the dry air emitted from the dehumidifier needs to be as hot as possible for best drying results.
- In one embodiment, the suction blower may be located at the underside of the dehumidifier in the housing. Then the dehumidifier can be heated by convection from rising air heated by the suction blower in the housing.
- The sound and heat insulation may be a laminate comprising a thicker insulating and damping layer and a thinner reflective layer. Thereby the dryer can easily be heat and sound insulated.

FIG. 4 is a diagrammatic plan view showing a drying apparatus ofFIG. 1 during an alternative drying operation where the floor structure has two outlet openings. - In the drawings, wherever possible, same reference numerals are throughout used for components with the same or similar function.
- In the embodiment shown in
FIG. 1 , thedrying apparatus 100 according to the invention is intended to dry a water damagedfloor structure 10 of the type having adamp proofing layer 30 in anintermediate layer 32 having an air gap between aflooring 20 and asubfloor 40. - Typically, in such a
floor structure 10, theflooring 20 may consist of asurface layer 22, achipboard layer 24 and a heat-insulatinglayer 26 of cellular plastic, while thesubfloor 40 may consist of a base/baseplate 42 of concrete and a soundproofing cellularplastic layer 44. Thedamp proofing layer 30 may be a membrane known under the trademark Platon® which is formed with a pattern of projections projecting at least from a bottom side 34 of the membrane to define theair gap 32 between thesubfloor 40 and theflooring 20. - In the
flooring 20, e.g. with a cutter not shown, aspace 80 is opened-up down to thedamp proofing layer 30. Thespace 80 provides access to thedamp proofing layer 30 to form adry air inlet 38 therewith. Thedry air inlet 38 can be made with any suitable means, e.g. manually with a knife (not shown), which cuts an opening in the layer, after which the material thus cut away is removed. - At the top of the
flooring 20, thespace 80 is sealed closed by aplate 70 during the drying operation described below. Theplate 70 may have a pair of through-tubes dry air conduit 56 and aprocess air conduit 66, in turn, extending to a respectivedry air outlet 52 and aprocess air inlet 64 of thedrying apparatus 100. Thedry air conduit 56 extends through thespace 80 and into thedry air inlet 38 where it is sealed by a suitable sealing agent, such as bitumen. Theprocess air conduit 66, in turn, extends only into thespace 80 which can be regarded as an outlet orifice chamber for humid process air. Theplate 70 may be attached and sealed to theflooring 20 by suitable means not shown, e.g. glue or screws and sealing strips. - The drying operation is carried out such that the
drying device 100 creates a strong underpressure and drawsprocess air 68 from theprocess air line 66 while pressing heateddry air 58 into thedry air line 56. The heateddry air 58 is spread in all directions while accumulating moisture from thesubfloor 40. When theprocess air 68 reaches the end edges of thelayer 30, it is forced by the strong underpressure to change direction and flow radially toward thespace 80 and accumulate more moisture in the portion of thegap 32 at the the top oflayer 30. Theprocess air 68 then enters thespace 80, from which it is sucked into theprocess air line 66 and further to thedrying apparatus 100. - The
drying apparatus 100 has ahousing 102 with an internal sound and heat insulation. The sound and heat insulation comprises a laminate having a thicker sound attenuating andheat insulating layer 104 and a thinner sound and heat reflecting layer orfilm 106. The laminate may be adhered to the interior of thehousing 102. - Within the sound and
heat insulation housing 102, adehumidifier 50 is mounted parallel to asuction blower 60. More specifically, thedehumidifier 50, in a manner not shown per se, is suitably installed on one side of thehousing 102, and thesuction blower 60 is mounted in close heat conductive contact directly to a bottom side of thedehumidifier 50. - As can be seen most clearly in
FIG. 1 , thesuction blower 60 is a side channel blower including anelectric motor 122 and acentrifugal blower housing 124, which has asuction duct 126 arranged to be connected to the above-mentionedprocess air line 66, and anoutlet duct 128 connected to aninlet 152 of thedehumidifier 50. - Dehumidifier 50 is a sorption dehumidifier having an
inlet 170 forprocess air 172 from the environment. At theinlet 170 there is a fan or blower, such as aduct fan 154, to increase the flow rate of theprocess air flow 172 from the environment mixed with theprocess air flow 68 heated by the suction blower further into thedehumidifier 50. After thefan 154, the process air is conducted into asorption block 156 which can be of a rotating type. Thesorption block 156 has an absorbent for accumulating moisture in the process air and is capable of dividing the outgoing flow into the above-mentioned dry-air flow 58 and a wet-air flow 78 which is discharged from thedrying apparatus 100 through anoutlet duct 162, from which it can be discharged through a wet-air conduit 76.Dehumidifier 50 also has aregeneration chamber 158 in which there is a self-regulating so-called PTC (Positive Temperature Coefficient)element 160 to further heat the resulting dry air when needed. Without such a PTC element, dehumidification would deteriorate by activating an over-heat protective device and thereby degrading operation. - In
FIG. 2 , there is also shown a slightly modifieddryer device 100 mounted on ahand trolley 108 to be easily moved over shorter distances. - In the embodiment shown in
FIG. 3 , thedrying apparatus 100 according to the invention is intended to dry a moisture-damagedfloor structure 10 of the kind which, below aflooring 20 with asurface layer 22, has anintermediate layer 32 in the form of a porous heat-insulating layer between anupper concrete layer 42′ and a lower concrete layer/subfloor 40 such as a frame/base plate in a building wall. In this example, therefore, there is no moisture-protecting layer or air gap as in the example already described. The air transported here and collecting moisture in theintermediate layer 32 can now flow more uniformly in the porous layer between the inlet opening 38 and the outlet opening 80, which in this case are arranged at greater distances from each other in the floor structure. -
FIG. 4 shows the possibility of suckingprocess air 68 from twooutlet openings 80 in thefloor structure 10 with thedrying apparatus 100. In a manner not shown more than twooutlet openings 80 are likewise possible. Even more than oneinlet port 38 can be used. - As initially indicated, the drying apparatus according to the invention can also be used in applications where the dry air is not returned to the floor structure. The heated dry air can then for example be used to transfer heat to the floor structure (not shown).
- The above detailed description is primarily intended to facilitate understanding and no unnecessary limitations of the invention are to be construed therefrom. The modifications which will become apparent to those skilled in the art upon review of the specification may be made without departing from the scope of the appended claims.
