Definitions

  • the present invention relates to a method for reducing or avoiding the formation and smell of mildew in buildings and being of the kind defined in the preamble of Claim 1.
  • the invention also relates to a device for carrying out the method.
  • foundations that include a crawl space that is situated beneath a wooden floor and enclosed by walls comprised of stone, cement, or concrete.
  • Such structures are subjected to high humidities, particularly in summer, when the warm outdoor air is cooled by the colder ground and foundations, as the air flows into the crawl space between ground and floor. This causes the wooden structure to be affected with mildew and other forms of fungus, resulting in strong smells that spread within the building.
  • both an dehumidifier and a fan are required to achieve a satisfactory function, due to the fact that the moist air capacity of the dehumidifier, a typical value of which is 50 m 3 /h, is not large enough to generate a satisfactory subpressure.
  • One object of the present invention is to provide a method and a device with which the aforesaid problem can be solved at low cost.
  • the inventive features set forth in the characterizing clause of claim 1 solve the aforesaid problem in a surprisingly simple manner.
  • the invention thus obviates the need of a separate fan to maintain the subpressure in said space, provided that it is ensured that part of the process air delivered to the dehumidifier and pressurized by its fan is led away from the dehumidifier and out of said space, without passing the rotor of said dehumidifier.
  • a normal air flow of 600 m 3 /h delivered to a "standard" size dehumidifier may be divided so that 350 m 3 /h of air is allowed to pass the rotor of the dehumidifier during an air heating and dehumidifying phase while 50 m 3 /h of moist air passes through the moist air outlet and is conducted to atmosphere outside the crawl space together with 200 m 3 /h of process air that has been pressurized by the fan of the dehumidifier, this pressurized process air passing to atmosphere in the form of "leakage or seepage air" through one or more leakage openings in the dehumidifier casing, without passing the rotor of the dehumidifier.
  • the method enables the subpressure in the crawl space to be readily adjusted with the aid of a throttle valve or similar valve means in the dehumidifier outlet for dry and warm air. Actuation of the throttle valve in its closing direction will cause a relatively large volume of leakage air to be passed to atmosphere, therewith resulting in a higher subpressure in said space.
  • the volume of process air delivered may also be adjusted in a typical fashion, with the aid of a throttle valve or similar valve means in the process air inlet of the dehumidifier.
  • the invention also relates to device that operates in accordance with the described method and that has the characteristic features set forth in Claim 4.
  • Figure 1 shows a building 1 that includes side walls 1a and wooden floor structure 1b, said building resting on a cement or concrete foundation 1c (so-called small cottage foundation) that surrounds a crawl space 2 beneath the floor structure 1b.
  • a cement or concrete foundation 1c so-called small cottage foundation
  • a dehumidifier 3 that includes a housing or casing 3a, an inlet pipe 3b, a warmed and dried air outlet pipe 3c, and a connection with an outlet pipe intended for moist air separated in the dehumidifier and located in the ambient atmosphere.
  • a throttle valve 10 for adjusting the volume of process air delivered to the fan 4 of the dehumidifier is disposed in the inlet pipe 3b.
  • a major part of the process air delivered to the dehumidifier and pressurized by the fan 4 is allowed to pass the rotor 5 of said dehumidifier.
  • a casing 5a that houses heat emitting devices (not shown) so that dried and heated air leaves the dehumidifier via the outlet pipe 3c.
  • Moist air separated in the rotor 5 leaves the dehumidifier via a collecting vessel 5b provided on the primary side of the rotor and having a moist air outlet pipe 3d.
  • the moist air outlet pipe 3d opens into the outlet pipe 3e.
  • This latter pipe 3e is encircled by a ring-shaped opening in the casing 3a, such as to form a dehumidifier exhaust opening for leakage or seepage air that has been pressurized by the fan 4.
  • an outlet conduit 12 Connected to the dehumidifier outlet pipe 3a is an outlet conduit 12 through which moist air exiting from the pipe 3d and said leakage air are both conducted to atmosphere outside the space 2, through the opening 6.
  • the subpressure in the crawl space can be readily adjusted with the aid of a throttle valve or butterfly valve 11 provided in the dehumidifier outlet pipe 3c. Actuation of the valve 11 in its valve closing direction will thus increase the volume of leakage air that departs through the ring-shaped opening 6 and therewith also increase the subpressure in the space 2.
  • FIG 3 is a cross-sectional view of part of the dehumidifier shown in Figure 2, and illustrates a variant of the moist air outlet.
  • the moist air outlet pipe 3d conveniently extends concentrically inside the outlet conduit 12 for pressurized leakage air, and terminates in the ambient atmosphere outside the foundations 1c.
  • the moist air outlet pipe 3d need not extend concentrically inside the outlet conduit 12.
  • pressurized leakage air can alternatively be led from the dehumidifier to the atmosphere outside the crawl space 2 through a completely separate conduit means.
