Four projects of SPbGASU graduates were awarded diplomas from a competition of final qualifying works held by the Association of Construction Universities (ACU).

In the category “Bachelor's project in the field of heat and gas supply and ventilation”, third place went to Ilya Fedotov (supervisor – Dean of the Faculty of Environmental Engineering and Municipal Services, Associate Professor at the SPbGASU Department of Heat and Gas Supply and Ventilation Inna Sukhanova) for the FQW “Heating and ventilation of a 24-storey building with built-in premises in Moscow."

“The author paid special attention to improving the calculations of heating and ventilation systems in modern software systems. He turned to equipment developers to obtain information required for the software systems. The solutions proposed in the FQW will speed up the process of calculating heating and ventilation systems and, most importantly, will increase its accuracy,” said Inna Sukhanova.

In the nomination “Master’s research work in the field of heat and gas supply and ventilation”, third place went to Egor Ilyin (supervised by Professor at the Department of Heat and Gas Supply and Ventilation Vera Ulyasheva), the author of the thesis “Study of the organization of air exchange in clean rooms of pharmaceutical production of the Scientific and Technical Center “Polisan””.

The author and his supervisor are confident that the research topic is in demand. The need for medicines and vaccines is growing every year, and pharmaceutical research is expanding. Consequently, the need for pharmaceutical production infrastructure: drug production plants, research centers is increasing. Any such production cannot do without air conditioning systems.

“The work is devoted to identifying the most energy-efficient and economical method of supplying air to the clean room of a scientific and technological center. Regulatory documents provide for four such methods. I came to the conclusion that the optimal method is to supply air with mixed flows. Installation costs, equipment costs for 2022, and operating costs are significantly lower than others. The results were obtained on the basis of mathematical modeling in the Star CCM+ program and cost estimates upon request to the specialized installation company and equipment suppliers,” said Egor Ilyin, who is continuing his studies in the PhD school.

Based on the final work, a recommendation will be developed for the design of air conditioning systems for pharmaceutical production according to the criteria of energy efficiency and cost-effectiveness; and the mixed flow air supply method will also be improved.

In the nomination “Master’s project in the field of heat and gas supply and ventilation”, first place was given to Anastasia Bogataya (supervisor – head of the Department of Heat and Gas Supply and Ventilation Nikolay Ponomarev), author of a thesis on the topic “Ventilation of the small hall of the Opera and Ballet Theater in Sevastopol”.

The author of the work built a geometric model of the room and carried out mathematical modeling of the air distribution process in a small theater hall. As a result of the modeling, the calculated values of the microclimate parameters were obtained, and their comparative analysis with the standardized values was also provided.

In the nomination “Master’s project in the field of heat and gas supply and ventilation”, third place was taken by Snezhana Beresneva (supervisor – associate professor at the Department of Heat and Gas Supply and Ventilation Viktor Pukhkal) with the thesis “Heating and ventilation of protective structures of civil defense”.

Viktor Pukhkal reported on the relevance of the work and research - it is determined by the significant number of shelters and civil defense shelters on the territory of the Russian Federation, which should provide protection to the population in emergency situations. Regulatory requirements for the design of protective structures cover only general data, without taking into account the specifics. The basic courses “Heating” and “Ventilation” do not cover solutions for civil defense protective structures, so Snezhana Beresneva had to study many questions on her own.
