Air temperature and humidity are undoubtedly among the most important aspects that affect indoor quality in places where people stay. To ensure comfort conditions, these properties need to be controlled precisely, both in the spaces used by individual guests, and in common areas, such as restaurants, halls or conference rooms.
Throughout the summer, for example, hot outside air needs to be cooled down to a comfortable temperature, around 20-25°C. To do this, air handling units can be equipped with evaporative cooling systems, which atomise water into very fine droplets that evaporate spontaneously, absorbing heat from the air and thus cooling it. The same systems can also be used to cool outdoor lounges, creating a welcoming and relaxing environment.During the winter, on the other hand, the air supplied by heating systems can be very dry, with relative humidity even as low as 10-30%. In these conditions, the human body tends a release moisture, causing dry skin, cracked lips and eye irritations. As well as these discomforts, dry air can also cause recurring sore throat and help spread typical winter illnesses.To overcome these problems, relative humidity needs to be kept within values that guarantee comfort conditions, typically between 40 and 60%, using either steam humidifiers or adiabatic systems.Maintaining the right humidity level allows means less dust in the air from carpets, pillows or curtains, thus further reducing the possibility of respiratory problems for people who suffer from allergies or asthma. It also means less buildup of static electricity, something that is annoying when charges accumulate on clothes, door handles or hair.Air quality is important not only in spaces dedicated to guests, but also for correct management of the others services supplied. For example, food storage in cold rooms may require high humidity levels, so as to preserve the appearance and freshness of food.One other application often found especially in luxury hotels involves steam baths, where a special humidifier keeps the environment saturated with steam at a temperature between 40 and 45°C, allowing the body to relax and cleanse itself of toxins.
Humidification in winter for maximum guest comfort means:
- Avoiding the discomfort due excessively dry air;
- Reducing the amount of dust in the air;
- Limiting the buildup of static electricity;
- Adiabatic systems for air-conditioning in summer:
- Green solutions for cooling the air, with minimum energy consumption;
- Specific solutions for steam baths or other guest services.
