Heating, ventilation, and air conditioning is a technology, what makes our indoor environment comfortable and provides acceptable air quality. Today, it has become an indispensable device for every household, what greatly improves people's quality of life and contributes to people's health. Compared with the HVAC in residential buildings such as apartments or office buildings, the HVAC in hospitals always have more power consumption, stricter requirements, not only of a higher air quality but also of a securer air supply. How to meet the requirements with minimal energy consumption, this is a challenge for the equipment and the same time for the controlling strategy.

The main HVAC of UKA is one of the biggest air-conditioning systems in Europe. Its supply air volume flow rate can reach millions cubic meters per hour and its structure is certainly complicated with an extremely huge duct network. As part of UKA, Isotopenlabor area has an independent air-conditioning system. This area contains patient rooms, laboratory rooms, examination rooms, etc. That means it has same strict requirements on the air quality, supply security and room environment as the main HVAC. In consideration of the replicability, we choose the HVAC in Isotopenlabor as our test subject in this work. Through simulation with different scenarios, we aim to find an optimized operation of the HVAC in Isotopenlabor. The results have reference value to the study of the main HVAC of UKA that we can implement in the next step.
