Abstract
One of the components and integral parts of our daily life is the climate. This is especially true in the rooms where we spend most of our time. The movement of air masses, temperature, humidity-all this affects us. Therefore, it is very important to maintain the necessary, comfortable indoor climate regime. In this paper, the use of a fuzzy logic controller for control humidity in sport halls. We compare performance of controllers of similar researches and their energy efficiency rate. Different humidity setting and outdoor humidity rate give different results. The results show that the proposed controller is always have lower energy consumption compared to conventional systems. Energy saving achieved is between 27 to 39%.
