AIR HANDLING UNITS


This article explores the nuances of humidity control within AHUs, highlighting its significance and the innovative solutions available to address common challenges


C


ooling coils in AHUs are the unsung heroes during the humid summer months, efficiently extracting excess moisture from the air. This


dehumidification process is vital for maintaining comfortable and healthy indoor environments during this period. However, the winter presents a challenge. As the cold fresh air is heated, moisture levels drop, leading to dry conditions that can trigger various issues. This highlights the importance of incorporating humidity control in the initial design phase of AHUs, ensuring they are equipped to address both extremes. The discovery of inadequate humidity levels


in operational AHUs, whether newly installed or long-standing, is not a dead end. Tailored solutions, such as bespoke steam lances, can be introduced to mitigate these issues. Designed for compact spaces, these lances provide precise humidity adjustments, preventing the common problem of ductwork dampness and ensuring that even the most constrained systems can achieve optimal humidity. In environments such as hospitals and offices,


where the spread of viruses can cause major issues, humidity levels between 40-60% are crucial. This range is scientifically proven to reduce the transmission of common colds and other diseases.

Moreover, it’s imperative to ensure a consistent


supply of fresh air within buildings, especially during the colder months. The legal mandate requires that a minimum of 5-8 litres per second of fresh air per person is provided within indoor spaces. This constant influx of fresh air during winter necessitates the integration of effective humidification systems to counteract the naturally low relative humidity levels typical of this season, thereby maintaining the optimal humidity range for health and comfort. Addressing low humidity levels is not only critical


for human well-being but also essential for the preservation of various materials and the smooth operation of processes. For instance, low levels of humidity can cause cracking of paint on precious


artworks in museums, increased static and dust accumulation in printing and woodwork, as well as fluctuations in relative humidity levels in laboratories and cleanrooms where it is essential to maintain year-round stable conditions. As we advance in our understanding of indoor air


quality, the significance of humidity control within AHU systems cannot be overstated. By integrating smart design and innovative solutions, we can create environments that are not only comfortable but also conducive to health and well-being.
