Tunnelklimatisierung

Tunnelklimatisierung refers to the systems and technologies used to control the environmental conditions within tunnels. These conditions primarily involve temperature, humidity, and air quality, which are crucial for the safety, comfort, and operational efficiency of tunnel users and infrastructure. In road tunnels, ventilation systems are paramount to disperse exhaust fumes from vehicles, thereby preventing the buildup of harmful pollutants and maintaining visibility. Heating and cooling may also be employed, especially in extremely hot or cold climates, to ensure comfortable temperatures for drivers and to prevent condensation on tunnel surfaces which can reduce visibility and damage materials.

For underground railway tunnels, climate control systems are essential for passenger comfort and to manage the heat generated by trains and the friction of the wheels on the tracks. These systems often involve large-scale air handling units and chillers to maintain a consistent and pleasant temperature. Humidity control is also important to prevent corrosion of electrical equipment and to avoid discomfort for passengers. Air quality is monitored and maintained through filtration and the introduction of fresh air. The design and operation of tunnel climate control systems are complex, requiring careful consideration of factors such as tunnel length, traffic volume, energy efficiency, and environmental impact. Modern tunnel climate control systems often incorporate advanced monitoring and control technologies to optimize performance and respond to changing conditions.
