Abstract
A dehumidification device for drying air in a building or room space comprises a duct (7) so angled as to allow condensate formed in the duct to trickle down the duct (7) into a tube (4). Air from the room enters the duct via a grille (6). The duct is cooled by outside air entering the duct via a filter (8). The duct may be mounted in the ceiling (Fig 2). The dehumidification device requires no power source.
Description
1 Dehumidifier 2336427 This invention relates to apparatus for drying the
air in a building or room space and to a condenser and discharge for such apparatus.
In efforts to reduce the energy required to heat buildings, designers have increasingly made provision in new and existing buildings to reduce air passages between the insides of the buddings and the outside atmosphere to minimise heat loss occurring by the movement of air into and out of the buildings. However, in domestic dwellings in particular, the consequent reduction in ventilation during the colder seasons aggravates the difficulty of dispersing moisture to the outside from for instance washing and cooking.
Dry air has an insulation effect that requires less heat input to feel warm. Additionally the reduction of excess humidity enables a healthier environment as it reduces the migration and production of mould spores.
It is known to provide buildings, or rooms within buildings, with dehunuidifier apparatus which are powered as a refrigerator device, arranged to condense excess moisture from the air.
It is the object of this invention to provide drying of the air within the building with minimum intake of external air without need for powered equipment thereby nummising energy losses.
It is known to provide buildings, or rooms within buildings a dehurruidifier as a mechanism to dry the surrounding air, the most popular type are the units which with the refrigeration process provide a cold plate, condensate occurs on these cold plates causing drying of the surrounding air. The use of these devices are limited due to the energy usage in terms of electrical running cost, purchase cost and maintenance requirements.
2 In the present invention a cold surface is created using intake air and heat conduction ftom the external of the building, the chilled surfaces then act as a condenser for moisture with a condensate channel running to the external. This form of dehumidifier will operate when the external air temperatures are low and the internal humidity and temperatures are higher.
Dehumidification apparatus in accordance with the present invention is characterised by a filtered air bleed inlet which enables trickle ventilation from external air, the surface of the casing of the apparatus is cooled down by the intake of external air along with any heat losses from apparatus due to contact and close proximity to the external surfaces of the building. The cold surface causes the surrounding air to become an area of low partial vapour pressure. Air contairuing high water vapour pressure is readily attracted to the area of air with a low water vapour pressure. The cold surface of the ducting acts as a condenser with the resultant condensate within the ducting being fed by gravity to the outside of the building.
A dehumidifier apparatus in accordance with the present invention will now be described, by way of example, with reference to the accompanying drawings, in which Figure 1 Shows the system through external wall Figure 2 Shows the system through ceiling in to the attic space.
The dehunudification system comprises a condenser 5 mounted in an external wall of a conventional domestic dwelling, either close to the major moisture sources in the kitchen or bathroom, bedrooms or any part of the dwelling requiring dehumidification.
The condenser 5, duct 7 are positioned through the wall at a downward sloop to the external at an angle of about 40 this is to be a sufficient angle to cause condensate to trickle down the condenser through the condensate intake tube 4 to the external outlet '). The trickle air inlet 1 filters 8 and disperses the external air within the condenser, the small inlet of the filter dissipating drafts caused 3 through external air currents. This trickle of air ensures the condenser 5 remains cool. Additionally heat from the condenser is conducted through the material of the wall. Air inlet grille 6 guides the warmer incoming air at high level while the cooler return air flows out at the lower level.
In figure 2 the condenser 5 is mounted vertically through the ceiling and into the loft space. The condenser is kept cool by the surrounding cool air in the attic 12, with condensate sliding down the condenser wall and discharging via the condensation trap 4 through sofit 13 within condensate outlet tube 3.
