Adiabatic cooling is an effective way of cooling and is based on cooling air by evaporating water. It is not for nothing that this method of cooling is also called evaporative cooling. The energy required for evaporation is extracted from the air, which cools it down as a result. This principle occurs frequently in nature and has also been applied by humans in the distant past.<\/p>\n

There are two methods of evaporative cooling: direct or indirect. In both methods, air is cooled by evaporating water. The starting point here is that for 0.7 kW cooling, about 1 liter of water is needed per hour. This way of cooling works more effectively when the outside temperature increases. For example, at an outside temperature of more than 30O<\/sup>C the indoor climate 10O<\/sup>C or more are cooled.<\/p>\n

Direct evaporative cooling<\/strong>
<\/u>With direct adiabatic cooling, the air to be cooled (usually outside air) is drawn through a package saturated with water. This package is made of a material that can contain a lot of water, such as cellulose or paper. This package is kept moist.<\/p>\n

On the package, some of the water in the supply air stream evaporates. This makes it more humid and the temperature of the air decreases as a result. The air resistance of the direct adiabatic cooling section is virtually nil, so that hardly any extra energy needs to be added to the supply fan. As a result, energy consumption is also limited. For example, only 1 kW of energy is needed to generate 10,000 m3<\/sup>\/h to cool. This makes the air more humid.<\/p>\n

Indirect evaporative cooling<\/strong>
<\/u>In indirect systems, the air cooled by evaporation does not enter the room directly, but the cold is transferred to another air stream via a heat exchanger. This more complex principle is chosen if the final relative humidity in the room is not pleasant.<\/p>\n

Indirect adiabatic cooling therefore works with two air flows, namely the humidified return air and the supply air to be cooled. The return air is humidified and passed through the heat exchanger, where it transfers its cold to the heat exchanger and is then discharged outside. In the heat exchanger, the supply air (outdoor air) can absorb cold without becoming humid itself and then cool the room to be conditioned.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t\t\t\t\t

Healthy indoor climate due to good relative humidity<\/h2>\n

Humidity in the house has a lot of influence on the indoor climate and on our health. In colder weather, the chance of low humidity is greater. You often notice this in dry air in the house, which can cause health problems such as dry skin or throat, but also cracks and tears in wooden furniture, floors and frames. How do you know if you are dealing with low humidity in your home and what can you do about it?<\/strong><\/p>\n

What is humidity?<\/strong><\/p>\n

First of all, it is good to know what humidity is exactly. We often talk about the relative humidity. This percentage indicates the amount of water vapor in the air in relation to the maximum amount of water vapor at a given air pressure and temperature. To give an example: if the relative humidity is 50 percent, the air contains half the maximum amount of water vapor.<\/p>\n

When is the humidity too low?<\/strong><\/p>\n

In general, you can use these percentages to check how the humidity is in your area.<\/p>\n
