Control of humidity

To drain the surrounding residential surface water, ground surrounding residential land should be outward and downward into the slope, slope gradient should be maintained at every third ramp meters under the level of 14-25 mm. Water drainage pipe with the foundation should maintain a distance of a few feet, the water discharges from residential to lead. To ensure that buried underground drainage pipes to normal, owners should use the hose pipes on all tests There will be failures of the drain pipe for the replacement or repair. In addition, all lanes, sidewalks and gardens should be based along the wall downward slope built outside, and the gradient of the slope should be maintained in every third ramp meters under 6 mm level. In extreme cases, the owners also found on the original foundation around the ground, and the laying of the drainage layer of gravel or brick, such as the outstanding performance of the drainage material. Since this method has been used in houses built higher costs Owners whether it is necessary to take this approach should seek expert advice. In some cases, residential or may not have enough space for proper drainage, owners often choose in the basement and the ground floor space to install drainage tiles and underground wells pump; However, the drainage tiles and underground wells pump, the cost is very expensive.

The slopes around the foundation columns : residential ground around the foundation should be outside the downward slope built

Foundation walls and basement floors if moisture-proof underground space in the basement or ground soil to the ground, owners in the surface coating layer thickness of 6-mil polyethylene film. Laying, the owners should pay attention to make polyethylene membrane of the overlapping edge width to maintain at least one-third meter level. For the foundation walls of any cracks or joints, the owners should be closed or used for fill flexible coating.

The use of construction techniques to control water, air flow and vapor diffusion, condensation, building components and accelerate the use of dry construction techniques to reduce warmth, damp air contact with the cold surface to prevent the possibility of water vapor condensation, materials mold rot. These include the walls and roof of the high temperature side to control air flow and to install a vapor layer. Further, in order to prevent flood water from entering the rooms, the owners should use appropriate Rain and drainage technology. As for the building owners, and owners of the application should be based on local climatic conditions specific decisions.

Waterproof roofs rainproof roof is designed and constructed to prevent water entering the room key. In addition, careful to avoid steam holes in the building is occurring condensation in the roof and loft design must attach importance to the issue. In moisture-proof, no single-proof method can be applied to any climate of any residential. Dampproof buildings must consider the focus is how to prevent moisture from building shell temperature of the lower side of the flow of high temperatures side, and to prevent infiltration through the building envelope in the indoor moisture condensation on building materials.

Indoor proper ventilation, at least in the bathroom and kitchen installation row fans. To the whole of residential ventilation for the mechanical ventilation system is the best choice owners relative humidity indoors will bring higher mold , dust mites and other biological contaminants. In the bathroom and kitchen fans can be installed Pai Pai family members scattered in the day-to-day activities of the tidal, The indoor relative humidity at 50%. Against certain property owners concerned about the noise issue, the market has launched a quiet row of fans design products. Pai fans initiative constitutes a residential part of the ventilation system. in the kitchen and bathroom fans retrofit another advantage is that it would take away fans row indoor odors and pollutants. Apart from the bathroom, kitchen ventilation, Owners should also pay attention to clothes dryers / laundry in the work of the gaseous emissions are derived directly outdoors, prevent these gases into the mezzanine or other confined space.

Choosing a suitable horse for the dehumidifier dehumidifier aspirin bigger is not better. Dehumidifier inappropriate for the horse owners will bring operational and cost issues. Dehumidifier aspirin Although several large refrigeration quickly, but it will not help to reduce the indoor humidity level This could lead to higher relative humidity with the series of problems. Because solar radiation direction and Atmospheric Attenuation dehumidifier will affect heating, cooling load, Even identical homes should determine access to indoor heat loss and, and thus the power to determine dehumidifier. Appropriate amount of refrigerant and proper maintenance is the best performance dehumidifier play the key.

Prevention of low relative humidity below 30% relative humidity will be uncomfortable and lead to human mucosal dry thus triggering nosebleeds and infection. In general, only in winter outdoor air moisture fewer cases result in a lower relative humidity indoors. When dry outdoor air through the building envelope as a seamless and open into the rooms, indoor air will thus become dry. Outdoor air infiltration into the more indoor air is more dry. In response to this problem, hermetic owners use energy-saving technologies and reduce outdoor air infiltration, improve the indoor environmental control thus without the use of humidifiers for the circumstances and can maintain indoor humidity level appropriate. If owners use humidifying machine, the landlord must pay attention to humidifying machine maintenance, in order to prevent the breeding of biological pollutants.
