Evaporative cooling is a precise air control method used in medical institutions, museums, wine-making, printing and textile industries These is a wide variety of humidity management solutions in the production environment. The most preferred solutions are the adiabatic humidification and the water spraying. They are known to be the most preferred choice due to their dual advantage of both humidification and partial balance of internal thermal loads thanks to the evaporative cooling. Thus we get humidification and cooling of the air at the most important points of the workflow. Hlad Ltd offers a full range of products for high-quality and accurate air control. In the printing industry, a 10% change in the air humidity changes the paper size by about 0.1-0.2%, enough to affect the processing speed and clog the printing machine, causing economic damage. When the humidity control is missing, the quality defects can easily occur due to improper adhesion of ink to the surface, which leads to significant incensement of the waste. Therefore, the control of air humidity is fundamental to ensure the continuity of operations and to ensure the quality of the final product. In museums, the temperature and humidity control is important for the preservation of exhibits, most of the works of art, artifacts and documents. They are made of natural materials that are sensitive to the humidity of the environment in which they are stored. Canvas, wood, parchment and paper have a specific humidity that tends to balance with the humidity of the surrounding air. Changes in ambient temperature and humidity caused by external climatic conditions and endogenous factors, such as visitors, lighting, etc., turn into changes in the size and mechanical properties of these materials and can cause irreversible damage to the works of art. Therefore, in order to preserve the integrity of the artefacts, museums and libraries must provide specific environmental conditions that will be precisely maintained for different periods of time. In the wine industry, temperature and humidity control is of fundamental importance for preserving the organoleptic properties of wine throughout its life. In the increasingly competitive international market, the use of the most sophisticated technological systems can make an important contribution to provide the high-quality wine production. Ensuring the correct humidity and temperature and the ability to track the trends of these values during the seasons is an integral part of the winemaking process to produce wine with particular characteristics every year. Why is temperature and humidity control important in medical institutions? Our respiratory system is the first stage of our immune defense against viral infections such as influenza, respiratory syncytial virus (RSV) and the recent COVID-19 coronavirus. A relative humidity of 40 to 60 percent ensures the correct viscosity and thickness of the mucous membrane, in which several epithelial cilia trigger a protective process known as "mucosal clearance". This process is fundamental to our health, because usually it captures and cleanses most of the pathogens that we inhale. Simply by talking, breathing or coughing, people can introduce into the circulation a huge number of microbes contained in thousands of tiny droplets of moisture floating in the air. According to some studies, 10 to 33 percent of all pathogens that cause infections acquired in the field of health are spread at some stage of their lives, as described above - in the air. However, keeping the relative humidity in the room from 40 to 60 percent helps to limit the droplets remain to approximately one size (100 microns) and tend to settle within about 1-2 m from the source and thus can be eliminated much more efficiently using traditional cleaning methods. The internal environment is very important to us. We may not think about it, but on average we spend about 90 percent of our day indoors and have a significant impact, for better or worse, on the air quality in the buildings where we spend our time. For the most part, conditions inside buildings depend on the properties of the air we breathe, also known as indoor air quality. As for modern buildings, which are increasingly isolated, indoor air conditions are mainly determined by how the HVAC system (heating, ventilation and air conditioning) meets the needs of temperature and humidity of the human body.
