| Abstract [eng] |
The main aim of the final project – the project aims to minimize thermal bridges while reducing heat losses, taking into account the design of less energy wasting heating and ventilation systems for the multifunctional center. The paper consists of two main parts: the research part and the project part. In the first part of the paper the thermal bridges’ research was carried out. The „Therm6“ programme was used for two-dimensional outdoor temperature calculation through partitioning constructions. Reduction of thermal bridges, selection of materials and the method of problematic node’s installation were carried out during the research. The causes listed above helped to decrease the heating expenses of the building. In the second part the heating and ventilation systems for the multifunctional centre were designed. New heating point, which will be connected to the city networks, was designed in the building. Collector-radiator heating system was provided for the building. The coolant temperature in the circuit, at the maximum heat demand, – 80/60°C. Seven recuperative systems were designed to ventilate the building. For five of them water air heaters were designed, whose maximum coolant temperature – 80/60°C. Seven separate systems were designed to remove air from the sanitary units. Separate air ventilation system was designed to remove air from the kitchen. |
