Experience in designing the supply- and-exhaust ventilation systems on the example of the premises of the office center in Tobolsk

Тhe article reviews examples of design and comparison of supply, exhaust and supply-andexhaust ventilation systems in particular rooms of the office center in the city of Tobolsk. The advantages of the device of supply-and-exhaust units with a heat recovery in rooms with excess heat are considered. The design schemes of two variants of ventilation systems are given: autonomous and supply-andexhaust. Aerodynamic calculations of ventilation systems were performed and presented in the form of tables. A technical and economic comparison of the version of the ventilation system with a plate heat recovery and the version without it was carried out. The ventilation equipment was selected. Summing up the results, it can be concluded that it is advisable to use the option of designing a supply-and-exhaust ventilation system with a plate heat recovery.Besides, the authors consider the methods of heat energy recovery in the supply-and-exhaust ventilation systems in particular office premises, which significantly reduce the consumption of thermal and electrical energy. Designs with a heat recovery eliminate unnecessary costs for heating the outside air. Due to the constant increase in tariffs for basic energy resources, air recovery becomes necessary and uses in the design of ventilation systems.
