Now there are more and more villas with basement on the first floor, and we are paying more and more attention to and concerned about the function of the basement. Some customers will even raise 1 meter on the overhead when they decorate and transform, so that the underground part of the activity space is bigger and more comfortable.
Following the clear division of the area, the emphasis is placed on the environment and state of the underground space.
[How to effectively do a good job of moisture-proof dehumidification, so that the villa basement as a whole to maintain a dry state and can be highly utilized] is the focus of designers urgently to solve.
From the subjective experience, the reason why people feel cold refers to the low somatosensory temperature (somatosensory temperature is the human body's perception of the surrounding environment) and the factors affecting the somatosensory temperature are not only air temperature, wind power, but also relative humidity.
Here's a tip:
According to the somatosensory temperature formula of the Central Meteorological Station, at 5℃, the relative humidity is 70%, and the somatosensory temperature is 2.6℃;
When the relative humidity reaches 90%, the body temperature is only 1.2℃.
The southern region is mostly subtropical monsoon climate, and the north is mostly temperate continental climate, the southern precipitation is more than the north, air humidity of course far more than the north.
It also explains why indoor conditions in the south are colder than in the north, even if the air temperature is not much different.
In addition to air temperature, relative humidity also affects the comfort of a house.
The relative humidity of an enclosed environment is determined by two factors: air humidity (30%) and relative humidity of the building structure (70%).
The owners who value the functional planning of basement space will certainly do a good job in the dehumidification of the negative first floor. Then for the owners who have no comfort requirements temporarily, why do we still suggest that the basement (negative first floor) of the owners also need to do dehumidification?
Even if the basement is not used as a living space, it is necessary to do a good job of dehumidification and dehumidification.
Is water vapor itself is sinking, the basement temperature low humidity is big, this kind of circumstance only do on the first floor of the desiccant will increase its temperature difference with negative on the first floor, and, once produce hot and cold junction, if you don't do electroosmosis moistureproof, easily wall condensation problem, damage to building structure itself, thus greatly shorten its life.
If the damp proof problem of the negative first floor is solved well and it becomes a dry space suitable for human living, it can not only improve the space utilization rate for the owner; And the drying of the basement itself will greatly reduce the dehumidification pressure upstairs, and the utilization rate of fresh air floor heating will be reduced, which will not only reduce the corresponding warranty probability, but also save electricity and energy. It is the best way to kill multiple birds with one stone.
