The master's thesis introduces various air drying methods and especially focuses on air drying by using a rotary dryer for the purposes of pharmaceutical production in clean rooms. Clean rooms require high air quality, while achieving this entails high energy use. In the experimental part of the thesis, we firstly performed measurements on an existing air drying system with a rotary dryer and obtained the necessary data, which formed the basis for validating a computer model, created with the TRNSYS simulation tool. By using a computer model, we simulated the operation of a rotary dryer air drying system over a one-year time period. Based on the simulation, the energy consumption for the one-year time period was calculated. The computer model of the rotary dryer air drying system was then compared with a computer model of an air drying system using additional heat exchangers. We have found that, over a one-year time period, the energy consumption of the rotary dryer air drying system is lower than the energy consumption of an air drying system with additional heat exchangers.
