Humidifiers – do more than humid air
Physical basics of humidification
The total amount of water vapor present in a given volume of air is referred to as absolute humidity or vapor pressure. The amount of water vapor that can absorb this volume of air maximally increases with its temperature. The relative humidity (commonly known as relative humidity) refers to the ratio between the maximum possible amount of water vapor at a given temperature and the instantaneous amount of water vapor contained in the volume of air. It follows that only by increasing the air temperature, the relative humidity decreases.
Why do we need active humidification?
When we heat in the winter, we artificially increase the internal temperature without at the same time providing for the compensation of the missing moisture. The air is therefore, relatively speaking, drier. This creates risks and dangers for refined basic materials such as paper, textiles, leather, plastic or wood, but also in the IT area and not least in the office. In order to increase the relative humidity, the air must be humidified by using a humidifier when the room heats up.
How are room temperature and humidity related?
At different temperatures of the room air, quite different values of relative humidity may occur despite the same amount of water present. If, for example, the air at 10 ° C has a relative humidity of 50%, this drops only from 10 ° C to 23 ° C to 20% relative humidity by heating the air.
How are humidity and moisture content related?
When humidifying production and storage rooms in which hygroscopic (moisture-binding) material is treated, it is not enough to measure only the relative humidity of the room air. A significant proportion of the moisture requirement is the substance moisture content. If, for example, paper, cloth, leather, tobacco or foodstuffs are not in equilibrium with the ambient air, they extract moisture from the air until the balance is achieved. Conversely, of course, the air absorbs moisture until the mutual vapor pressures are balanced.
Without humidity no product quality
Is the room air quality correct in the production plant?
The raw materials are becoming increasingly demanding, the operating speeds of producing machines are becoming ever faster, and the quality requirements of customers are constantly increasing. Quality control is the focus of production and already begins with the purchase of materials: one should not rely solely on the pledges of the material suppliers. It makes a huge difference if there are more or less 2-3% moisture content in several tons of raw paper. Then you have to post-condition, pay attention to stable factors, the operating laboratory is under high pressure. One factor is often in the foreground: Is the room humidity in the production plant correct? We believe that these questions are easy to answer – with a modern and contemporary humidifier.
Humidifier for value retention
Who wants to protect antiques and similar values – in the private and especially in the museum area – knows how important a sufficiently high humidity for this is. Because if the air is too dry it will easily cause dry cracks in the wood and irreversible damage will result. Humidifiers provide relief here and ensure the preservation of the exhibits. But also in the wood processing industry, in the textile production and processing, or in the in-house printing, humidifiers ensure that the production materials are always optimally conditioned and sufficiently moistened.
Man and the air – The relationship has to be right
One adult needs between 11,500 and 14,500 liters of respiratory air a day. This means up to 29,000 inhalation and exhalation via nose and throat. However, too dry room air can significantly impede oxygen transport and oxygen uptake in the respiratory tract, which can lead to malaise, fatigue and lack of concentration. Adequate humidity helps strengthen the body’s resistance to colds, protects skin and eyes against dehydration and decisively improves its resistance. In particular: Prevention is better than cure. The subjective sense of comfort can be increased by using a corresponding humidifier. For example, a room temperature of only 17-18 ° C at a relative humidity of 60-70% is perceived as pleasant.
Maintenance is in the foreground
The quality of the humidifier water is crucial; it must be at least drinking water quality. Humidifiers require careful and responsible maintenance. Their constructive structure should not stand in the way of these efforts. Convenient handling, reliable unit parts, monitoring and safety equipment are now a matter of course. These are investments that pay off. Only humidifiers that are regularly maintained and maintained can also function optimally.
The evaporation principle
Water wets the humidifier surfaces (eg mats, windows) of the humidifier, which are exposed to an airflow. As a result, the water evaporates and is transported by the air flow into the room air. Devices of this principle extract heat from the environment, which results in evaporative cooling and cools the air (adiabatic cooling). Ideal are humidifiers, which carry out only the water-gas mixture with the air flow through their humidifier surfaces.
Due to the evaporation principle, only water vapor gets into the room air, so no moisture can be deposited in the room. In addition, a supersaturation of the room air is not possible. Last but not least, these devices are characterized by their very low energy consumption.
Evaporative humidifiers are mainly used in major technical facilities such as computer rooms and telephone exchanges, laboratories and libraries, as well as printers and hospitals. In music rooms, museums and art galleries, they also protect and preserve valuable furnishings. In addition, evaporative humidifiers are used to humidify process air conditioning systems and to humidify and cool production facilities, airports, warehouses and greenhouses. The indoor climate is an important factor in creating a healthy quality of living and must not be too dry or too humid. An optimal ratio is too difficult to realize without a humidifier, so you should not leave anything to chance. Humidifier Hub offers the perfect solution for this purpose to keep the humidity at the desired level. This may be necessary both in the apartment, as well as in storage and cellar rooms, for example, to preserve the building fabric and climate-sensitive objects from decay.
The functional principle of humidification
In order to regulate the level of humidity within a closed room, humidification devices that create an optimal climatic level are suitable. Humidifiers work according to the simple principle of evaporation and add air humidity to the air to be determined. Here we would like to explain the functioning of this principle in more detail and highlight the importance of humidifiers for increasing their own quality of life and the preservation of sensitive products and goods:
How does the evaporation principle work?
Air humidifiers basically consist of a motor for the air flow and a humidifier surface, which is in direct contact with the water, which is supplied via a tank system or a permanent water supply realized the device. A fan generates an airflow that applies water to the humidifier surfaces. The water evaporates and is transported by the air flow out of the device into the room air.
Adiabatic cooling – create well-being temperature and save costs
Humidifiers working on this principle extract heat from their environment. The evaporation process requires energy and converts it into evaporative cooling, which increases the humidity in the room. This so-called adiabatic cooling is responsible for the fact that the room temperature in winter can drop by a certain amount, without this leading to an impairment of the well-being temperature. The effect: You save expensive heating costs while maintaining the perceived temperature.
What advantages does the evaporation principle have?
Humidification with water vapor prevents moisture from condensing in the room. At the same time it is ensured that a moisture supersaturation can not take place. Since the evaporation takes place via the room heat, these devices work very energy efficient and are characterized by low consumption, which is a decisive positive factor, especially in long-term operation.
What can a humidifier be used for?
Most of the humidifiers that use the evaporation principle are used in industry and other large-scale technical facilities. Which includes:
- Computer rooms
To preserve works of art and musical instruments from deterioration, humidifiers can also be used in the following facilities:
- music rooms
Air humidification is also used to cool public buildings and industrial plants where a constant level of humidity is required. Which includes:
- Warehouses and halls
- production facilities
