Within the main points of this instructional approach it is clarified what humidity is, what types exist and how it is estimated. In general, it is known that Humidity is a common issue, some people experience its unfavorable effects on residential walls and ceilings, others are directly influenced.
It is clear that moisture is found everywhere, the question arises, but What is humidity? It is understood in simple words that, the moisture it is a measure of the water vapor notably contained in the ambient space.
You can constantly detect that there is some water vapor around it and the sum changes as indicated by different variables, for example in the case that it has just rained, that it is near the ocean, if there is vegetation on the ground or not, the temperature concentrated in the air, among others.
This means that anywhere you have water nearby with the potential to heat up and dissipate is a source of moisture, for example from the outside of waterways, lakes, moist soils and plants, where water may be readily available. strong form (solidified), fluid and vaporous (vapours) states.
Origin and detection of indoor humidity
To begin with, to find out the reason for the indoor humidity and its beginning, we must identify where we have the adhesion problem and how it shows itself. It is logical to know the type of humidity that influences the house, depending on how the inconveniences are presented.
Although it must be considered that, on multiple occasions, the signs that are shown in the structures of the openings or holes in the walls or walls of the structure, this could occur due to moisture by filtration. This can happen due to problems in the construction of the house, due to poor waterproofing or due to a problem in the system of pipes or channels, which could have a misfortune.
It is logical, in the wall that has an opening caused by humidity and noticeable stain, due to a break of water from its outer side. If you notice certain damp walls, or moisture droplets on glass and windows, it could be due to a soaking issue caused by the buildup of those rainwater runoff goths.
The humidity that occurs by condensation can also produce a quite appreciable malodorous odor and can be linked to the proximity of fungi and mold in the corners or protected walls. Should moisture occur in the ground floor spaces of the structure or appear to originate from the ground.
But if they do not reach a height of 1 meter on the wall, it is reasonable that the problem occurs due to rising damp. This can happen due to a problem of moisture incorporation into the soil and that it rises through the pores of the walls and the joints with the ground.
What is ambient humidity?
The soaking that is known as ambient humidity, is the measure of water vapor that is distinguished everywhere. It is very possible that it is expressed in absolute form in the case that it is called absolute humidity or in relative form if it is relative humidity or level of adhesion in the soaked.
Relative humidity is known as the ratio of the rate between the genuine measure of surrounding water vapor and what it would take for it to submerge at a similar temperature. A model: if the relative viscosity is 70%, it implies that of the 100% of that water vapor that the air can have, it would only have 70%.
humidity in the weather
The environment is the consequence of several cooperating elements, geological features, for example, mountains and oceans, affect their conditions. In this way, to designate the atmosphere, it is essential to investigate the temperature, air pressure and humidity that surrounds it.
It is clear that hygrometry is a part of materials science that reviews the reasons for the adherence of dew in the environment and the estimation of its diversities. Its name comes from the Greek hygroscopy, hygro that embodies wet and escopia that represents evaluation.
Methods for assessing moisture
Different techniques are used to examine the humidity of the air:
- Specific humidity
- Vapor pressure
- absolute humidity
- mixing ratio
As a general rule, in cold areas, it is the place where there is greater humidity, while in hot districts that soaking is lower. Wetness affects our daily life from numerous points of view and can influence it in an adverse and emphatic way, so it is very important to develop a Environmental awareness.
Humidity can end up influencing both our well-being and our mentality as well as the objects that include us, various common and apparent forms of creation, among other things. In this way, it is imperative to think about the idea of humidity, the opinions that are used and how it can influence us in our daily lives as well as in our homes.
atmospheric humidity
Air humidity is the sum (or volume) of water vapor found in the environment. This water vapor reaches the environment through the characteristic process of dissipation and comes especially from the seas, lakes, waterways, oceans and ice caps as well as evapotranspiration from the land, as well as vegetables and animals.
Understand that water is one of the vital components of planet Earth and is key to the biosphere because it provides food and work for many groups of species, so it is essential for the progress of life. Water vapor is the gas that is produced due to the dissipation process, where a compound component changes its physical state from a fluid to a vapor.
The degree of humidity present in a specific place will depend on certain explicit variables in the area, for example, the proximity of waterways, the recurrence of precipitation, the normal temperature of the air and vaporization.
Humidity is estimated using an instrument called a hygrometer, it tends to be used either to measure the level of humidity present around or from different gases. Air contains the most extreme ability to hold water vapor, depending on a particular temperature and pressure. This is called Saturation Humidity.
They are estimates that vary between 0%, which represents totally dry air without water vapor, up to 100%, whose value shows a domain totally soaked with water vapor, it is the initial stage of what is known as a dew point. .
Dew point
The dew point is the temperature point where water vapor, which is conserved in a specific situation, is converted to dew by means of methods in a process called accumulation (change of physical condition from vapor to fluid) and stays fast in zones.
At this temperature point, the relative humidity in the earth is 100% and when it can't hold any more water vapor, it consolidates and sticks to surfaces as dew falls. This process usually occurs when there is an extreme change in temperature.
For example, in nature, it can be seen at first light when the temperature drops, how the dew finds and stops on the surfaces of objects, plants, garden as well as other things that it can adhere to.
The dew manages to seep in both winter and summer, particularly in areas where the temperature has a perceptible contrast between day and night. When condensation occurs in nature at temperatures below zero degrees, dew turns to ice, enveloping the surface in a white sheen of limpid ice.
In contrast, in a closed domain the water vapor will consolidate in any area that is at a lower dew point temperature. For example, if you put a container of water in the refrigerator and when it gets cold you take it out, you will see that the water vapor in the ground will accumulate on the outside of the jar because it is at a lower temperature than the surrounding water vapor. . Something very similar happens when the person takes a bath, notice that both the tiles and the mirrors or the windows of the bathroom are fogged up.
Classification
Environmental pollution, an issue that can begin to be addressed by promoting the Environmental awareness , it can be displayed in the 3 different ways that were mentioned:
Absolute Humidity
It is the measure of water vapor, estimated in grams (g), that is available in a specific domain. It is determined per unit volume of air that is estimated in cubic meters (m3). It is used to evaluate the limit of the air that it covers to allow or not a more notable volume of water vapor.
Absolute humidity is the mass of water vapor that is available in a specific volume of air, before it settles (relative viscosity). Assume that temperature determines humidity because hot air masses have a greater ability to store water vapor than cold air masses. Absolute humidity is advertised in grams per cubic meter.
The contrast between relative humidity and absolute humidity is that the former is compared to a measure of velocity (the amount of water that can be held and is stored there) and the latter is compared to a ratio of the measure of water in air weight (determined in grams or kilograms).
Specific Humidity
This specific humidity is the measure of water vapor that has been remarkably contained within a specific domain. Smoke from water is estimated in grams (g), while for this situation air is estimated in kilograms (kg). This value is determined to decide the measure of moisture by weight that is required to soak one kilogram of dry air.
RH
It is the limit of air to hold water that is based on the immersion point (cut off that air to hold the water) and a specific temperature. Its calculation is determined by the remainder between the measurement of the vapor present in the environment.
Set aside by the largest sum it could contain, multiplied by one hundred (the result is advertised as a rate). A relative humidity of 100% shows that you have reached your limit point of immersion and from that point any amount of water vapor accumulates (becomes liquid).
Importance of Atmospheric Humidity
Moisture in the atmosphere fulfills some fundamental jobs in the terrestrial biosphere. In addition, it greatly affects the climatic condition and temperature of the Earth.
Water vapor is one of the gases that destroy ozone in the environment on Earth, which would not be a vital function for human development like other gases that also have causes on ozone, which is to keep heat in Earth's surface and blocking the bright rays of the Sun.
That is why the water vapor suspends part of the heat from the sun's rays and disperses them throughout the earth's surface, through its physical states through the hydrological processes of transpiration, evaporation, precipitation and condensation.
It is with these processes that the humidity of the atmosphere adds to the nutrition of the plants and the process of photosynthesis in an adequate way. This allows a development in the terrestrial vegetation without a great dependence on the water system, which is why it also implies a healthy importance for the rest of the species.
RH
The idea of relative humidity can be simply characterized as the connection between the measure of water vapor that is in the air (calling this idea absolute humidity), and the larger measure of water vapor that is achieved in nature. at that temperature in which it is found (designating the latter as total immersion adhesion).
This is why the temperature and pressure in a specific domain legitimately influence the relative humidity placed therein. A space or system can increase or decrease its relative humidity if there are changes in its temperature, in certain cases in pressure, or both. In a very cold air condition, a similar measure of water vapor produces a higher relative humidity than in an environment with warmer air.
The idea of relative humidity and warm comfort are exceptionally important in various areas of everyday life, from the feeling of comfort and solidity of the person, as well as the correct functioning of processes and innovations. Therefore, moisture-related parameters are controlled in various ways, from design to transportation advances.
They are exact relative humidity parameters that need to be adjusted not only in structures, for example, production lines, medical clinics, research facilities, and homes, but also in vehicles and methods of transportation, since control of these parameters is considered significant for human prosperity, security and the functioning of innovations.
Hygrothermal Comfort What is it?
Therefore, relative humidity, among the different qualities related to the atmosphere and temperature, is considered in what is called thermal comfort. Warm comfort, or actually called hygrothermal comfort, can be characterized as the comfort of the people involved in a situation with specific parameters of humidity and temperature.
It is what the human body is wired to respond to changes in the temperature of the earth around it. However, this response wastes metabolic vitality and can even damage well-being itself, in the case of scandalous conditions or those that are discovered over a long period of time.
Hygrothermal comfort characterizes a domain as thermally pleasant when the intercession of the body's thermoregulatory components (for example, the use of metabolic vitality, sweat, among others) is not vital for stationary movement and the use of light clothing.
An environment of warm satisfaction is created by maintaining a stationary movement (for example, sitting in a room) and wearing light clothes, so this feeling can be achieved between 20 ° C and 25 ° C, maintaining the relative humidity parameters of the Earth between 20% and 70% of course depending on the temperature, although the perfect range of Relative Humidity in a domain is between 50 and 60% mostly.
The hygrothermal consolation of an interior situation moves between the qualities defined according to the temperature of the open air and its relative adherence. Therefore, it tends to be lovely for us to pass heat from the sun into our house, in a cold season, for example, in winter. Although in the middle of the year, it is very possible that it will not be so charming.
This is due to the creation of heat by the individual and their trance with the earth, through what is known as homeostasis, where our way of life and that of other living creatures that manage the internal temperature depending on the external temperature They produce heat through synthetic changes that keep us alive.
Use of Relative Humidity
Both in the everyday field and in the logical field, the calculation of this relative humidity is essential to characterize the humidity present in an area. In the specialized logical and meteorological field, others work additionally with values and estimates, for example, absolute humidity and specific humidity.
However, in an increasingly regular and less specialized condition, relative humidity (RH) is particularly significant. In any case, why? The main reason is due to the way the human body is not sensitive to absolute humidity or explicit humidity, but is deeply influenced and sensitive to relative humidity.
In general, the air and the conditions can affect people in some way. Furthermore, not exclusively to individuals, but also to articles, matter and structures. In an area with low relative humidity, nature will generally gather moisture from the rest of the things in it, so it evaporates.
Although despite what might be expected, in a domain that features an abundance of relative humidity, it will generally exchange moisture with the rest of things, soaking them. This can affect people's well-being, as well as create conditions that cause certain materials and structures to crumble. For example, in cold atmospheres, the general external relative humidity adherence is normally high and the water vapor flow limit is low.
In higher indoor temperature conditions, the relative humidity is low and can cause the impact of dry air. This can cause distress in the human respiratory chart, making the nasal sections dry, broken and progressively powerless against certain diseases and respiratory blockages.
Delayed occasions in a low humidity adherence condition can cause nosebleeds, as well as uncomfortable and irritating respiratory hypersensitivities. In circumstances of exceptionally low surrounding humidity, with values below 20%, this may cause eye discomfort. Similarly, dry air can be harmful to the skin.
To stay away from this type of problem in homes and despite maintaining the proper functioning of the innovation tables and forms of creation in industrial facilities, research centers, between different offices, a structure is maintained using humidifiers, dehumidifiers and control panels. control for internal relative humidity in order to maintain explicit levels of humidity in the spaces.
humidity in the house
As mentioned earlier in this article, humidity in homes can have a negative influence, both for comfort and for well-being. In any case, the humidity inside the various homes can also influence the structures and furniture. The floor, on the walls in the foundations, the ceiling and the furniture can be influenced and spoiled due to indoor humidity.
Types of humidity
Moisture in the home can come in a few ways. The fundamental problem with having stickiness in the home or indoors is not just the tasteful outlook, but the moisture can lead to mold and mildew existence, which diminishes the nature of the soil in its quality.
Knowing the primary types of internal humidity is basic to have the option of solving the problems that cause it, despite considering future developments of unhealthy conditions for the human organism. These are the types of indoor humidity that are usually dealt with:
Moisture per filtration
Humidity by filtration, or horizontal filtration, progressively manifests itself in underground structures whose walls or walls are in contact with the ground or in regions close to water sources. It is a type of moisture that can greatly weaken the walls and can really deteriorate the structure of the home.
Also influence the electrical panels and damage the furniture of the home. It is important to predict in the development of a similar water inlet door that may cause this problem later on and prevent it with great protection.
Moisture by capillarity
In capillarity dampness, it rises as a result of the section of water through the pores and joints of the floor and the walls of the structure, which can influence both the floor and the wall at the base and baseboards.
It can be due to development errors during construction, lack of proper soil protection, or bursting or failure of canals and water delivery sources.
This can mean critical wear and tear on the structure of the house, in addition to causing damage to furniture, risks to the electrical panel and even medical problems. Keep a strategic distance from this problem with a good development in the construction from the first starting point despite controlling the possible problems in the pipes.
Condensation humidity
Moisture due to condensation can occur as a result of inadequate ventilation in the home or poor heat protection in building development closures and deserts. Condensation is created by the daily activities of the occupants of the house, for example, bathing, cooking.
It is important to maintain proper ventilation to maintain a strategic distance from moisture cling due to condensation, as it can cause fungus and mold, despite polluting the air and harming the well-being of the occupants of the house.
moisture on the walls
One of the fundamental humidity that walls can suffer from is humidity caused by capillarity. The water, humidity and minerals in the soil develop through the pores, joints and small spaces in the soil and baseboards, influencing the bottom of the walls and walls.
One of the possible reasons why this humidity appears is due to the non-appearance of the protective layer on the foundation or the fact that it is in poor condition. Another conceivable explanation is due to a terrible finish, both internal and external to the floor. This causes the thick floor mortar to come into contact with moisture, as it is not waterproof and retains it.
Regardless of whether, due to condensation moisture or ordinary floor washing, in addition to other things, moisture can pass under the plinth and low-lying areas of the floor, which at that time causes the assimilation of coarse mortar which then ends up being transmitted to the ramparts and the walls fine activity of capillarity. When the house is already built, there are 3 possible solutions that you can use when necessary:
Restore insulation with water repellent
This consists of perforating the wall on its sides to favor this problem and filling these holes with hydrophobic waterproof mix material, despite some plastic layer or black layer as an additional obstacle. It is one of the most used methods to treat this problem. In case everything is done, it is a generally excellent approach to take care of the problem.
Injection of waterproofing resin
In walls and walls that have humidity problems due to a thin activity by capillarity, it is logical to complete an aid treatment with silicone or waterproofing pitch, to avoid the rise of humidity through the cups of the walls.
Due to its considerable expense, this procedure is prescribed to be carried out on strong walls or ramparts, that is, they are not made of empty blocks or comparative materials since they would require exceptionally high measures of resin for the filling.
This is completed by saturating the openings to be made on one side of the wall, in a criss-cross example. The filling system takes a couple of days and must be done over and over again trusting that the silicone will enter the pores of the wall. When it comes into contact with moisture, it dries up and forms a defensive layer that prevents moisture section. This strategy is also powerful when done accurately.
Wireless electroosmosis
This procedure generally does not require extreme or significant changes. Remote electroosmosis is the position of an electronic device associated with a family unit outlet, better said, an outlet. What this electronic device does is converse the extremity of the dividers of the house and the ground using waves regulated by recurrence.
With this, what is obtained is the adjustment towards the humidity in the walls, in other words, instead of rising, the humidity falls towards the ground consistently, which affects the dynamic drying of the walls. This strategy is powerful, although it also works for soil moisture problems.
Wireless electroosmosis
Recurring tight waves have no influence on wellness and are easy as they are incredibly light to use. This strategy is powerful, although it also works for soil moisture problems. Recurring tight waves have no influence on wellness and are easy as they are incredibly light to use.
Obviously, the perfect thing is to stay from the earliest starting point, with long-term protection activities from the earliest starting point of construction development or coarse mortar interference strategies in the subgrade and applying the fill of the equivalent with a layer of mixture with water repellent.
Although, if this is beyond the realm of imagination since the house or room thereafter is existing, there is no compelling reason to emphasize that, with the options mentioned above, you can remedy the problem.
Another reason for damp walls could be condensation buildup. There are a few tips you should incorporate in case you need to stay away from this and other existing damp problems.
soil moisture
Moisture on the floor can be a little less bothersome than moisture on ceilings and walls, although it is not a major problem to manage. Moisture in the earth appears due to excess moisture in nature, that is, moisture due to condensation, so the floors are not suitable for drying.
Tight wicking moisture is also a difficulty that can influence floors, as the materials used for the subfloor (concrete is used to create concrete) have pores through which moisture rises from the ground.
This problem could be considerably more noticeable in regions close to evolving streams or conduits of water. Neutralizing this problem and at the same time maintaining a development in the correct construction of the house is the most appropriate, although it is obviously not possible to conceive if the house has just been built, so the problem must be solved after it appears. .
In fact, perhaps the most ideal approaches to handling this problem might be to purchase a dehumidifier. This is profoundly powerful in lessening the roughness in the soil and, along these lines, allows floors to dry out leaving moisture in the dark.
Dehumidifiers can keep the level of humidity in the house in solid ranges, between 40% and 60%. With these levels, moisture build-up problems should not be created, making it an effective, simple and quick approach to eliminating moisture problems due to condensation and the conceivable proximity of mold and mildew growth.
In addition, it does not require any kind of establishment and achieves favorable circumstances in different approaches, for example, less ventilation requirements in rooms, investment funds in heating and electrical energy utilization, situations with progressively wonderful temperatures in summer, and suffocating occasions. They are portable starting with one condition and then to the next and they are also effectively programmable.
Another conceivable arrangement (although it will require a bit more work), is the drift floor position. Since moisture created by buildup generally sticks to cooler surfaces, the drift deck could be a positive alternative that way.
Drifting (floating) floors are heavily used in re-designs of this type, particularly at events when a floor lift is not an alternative.
One of their main points of interest is that they are for all intents and purposes non-sticky on the floor as they are made of generally warm materials and with an overlapping extension that sits between the floor and the floor material that is slipping, for which creates a kind of isolated protection.
In a perfect world, in the event that you are just beginning the planning of the construction of the house, what must be presented to keep away from the humidity of the ground is a layer of polyethylene, between the ground and the foundation that protects between the house and ground.
Similarly, this strategy also protects the walls from thin moisture caused by capillarity. It is a simple and inexpensive growth technique, making it a powerful strategy to counteract and ward off moisture.
Tips to avoid general humidity in the home
As mentioned throughout the entire article, humidity in the home not only points to problems of good taste inside the home, damaging the structure or the furniture, but it can also influence the well-being of the members of the home. the house, as well as the different Types of Environmental Impact.
One of the reasons for indoor moisture problems is poor heat protection. This also increases the expense of home heating, so it's a point to remember to design from the ground up and maintain development propensities that will be increasingly efficient and grounded in the long term.
Although once the home or indoor space is built from now on, it should be kept away from moisture no matter how much it costs. For this it is essential to maintain certain practices or methods that help to refrain from creating moisture problems indoors:
Maintain adequate ventilation by constantly opening windows for a couple of hours and keep a current of air flowing through the house. Do this on low humidity days i.e. the point where the weather permits as in humid atmospheres this will only contribute to stacking the indoor condition with much higher humidity.
Put the clothes outside the house or have a shelf. Drying clothes inside the house helps to expand the humidity level in the space. In this line, the clothes should be dried outside the house, or separate a space for clothes that has great ventilation for that reason.
Put an air fan or ventilate the bathroom, the moment you take a shower, a lot of humidity is created that ends up in the areas of the house. Consequently, placing an extractor fan or properly ventilating the bathroom at shower time is important so as not to pile up the rest of the house with humidity.
At the time it is cooked, moisture is produced by heating or boiling water. You should get used to using a kitchen extractor fan or covering pots and compartments. Every once in a while you try to cover a somewhat worn wall with a household item.
This is a serious confusion, since in the event that the wear of that wall is due to humidity, at that moment the ventilation is being evacuated to that place, so the difficulty will be significantly greater, further breaking the structure and Even the furniture.
The idea of moving the furniture a little away from the wall is also prescribed, since the spaces through which the air does not circulate tend to be damaged, wet and produce fungus and accumulation. In the event that the house has problems with damp adhesion in the rooms, you can consider the use of a dehumidifier.
Try not to handle the plants inside the house, although it does not seem to be in this line, or it is not considered, this is a reality. A large number of plants adds to the spread of moist on earth.
They are compact, so they can be placed in different places in the home, despite having different programmable alternatives for different environmental conditions, which makes them an excellent option to reduce humidity in the space where it is warranted.
With these practices and tips, you will be able to contribute so that the house is not influenced by humidity. Obviously, to a great extent there can be different problems that offer a method for moisture, for example, poor heat protection, construction problems or problems with water systems and pipes.
We cannot get around this with these practices, as this will require different measures. In the same way, with these activities you can significantly reduce the surrounding stickiness in the home and thus maintain a strategic distance from problems of humidity, weakening, medical problems and even with economic savings in heating.
Humidity sensor
Humidity can be estimated with sensors that are modalities for measuring humidity, among them, the following stand out:
The hygrometer: That allows to decide the level of humidity of the air or of different gases. In meteorology, it measures the moisture content in the air in a very precise way.
The psychometer: Allows you to solve the measurement of steam that must be added to moist air to soak it, that is, it implicitly implies humidity when measuring it.
Clouds
Clouds they are framed by water droplets and different particles that are noticeably suspended around. These droplets originate from the accumulation of water vapor. In the event that there are Clouds in the sky, a fresh air mass has cooled enough to become soggy and begin to accumulate.
In the case that there are no clouds, it does not imply that there is no stickiness: the air constantly contains some of the water vapor, which occasionally does not contain enough to consolidate.
The importance of humidity in meteorology
Humidity is a really significant weather variable as water vapor is constantly present in our air. Regardless of the temperature of the air you inhale, it often has some of that water vapor that you get from ambient space.
That is why we are very used to seeing humidity, especially on the coldest days of winter, which is a very wet season. Water is one of the main parts of the environment and can be found in each of three states (gaseous, fluid, and strong).
