Abstract: Zhuretskii V.V., Yurkevych Yu.S. (supervisor). Designing of microclimate support systems in the hotel "Poseidon" in Mariupol, Donetsk region. Master’s thesis. - Lviv Polytechnic National University, Lviv, 2020. Extended abstract. In this master’s thesis microclimate support systems in the hotel "Poseidon" in Mariupol, Donetsk region. The source of heat supply is the roof boiler room, which is located above the technical 7th floor. Heating system ‘water two-pipe with horizontal wiring, polymer pipes, heating appliances - convectors brand Termo with built-in thermostatic valves. For the needs of the hot water supply system, water is prepared in an individual heating point. To ensure the design temperature in the bathrooms installed electric towel rails "Heat Point" STANDARD-HP-I. In the premises of the hotel complex to create the necessary sanitary and meteorological conditions inflow and exhaust ventilation is designed with mechanical and natural motivation in accordance with the requirements of current regulations. Air flow to the hotel rooms is served through the windows. Removal of air from living rooms is performed through bathrooms. The inflow into the restaurant premises is designed with mechanical motivation and is carried out by means of tidal installations of WOLF firm. Air supply is projected into the upper area of the room through anemostats and grilles. The intake of outside air is carried out through a louver grille, which is located above 2 meters from the ground. Exhaust systems are designed separately for each group of rooms. Exhaust air through air ducts and exhaust ducts is discharged above the roof. Exhaust air intake is provided from the upper area of the premises through anemostats and grilles, as well as through umbrellas above the kitchen equipment. The kitchens of the restaurant are designed with local exhaust ventilation, namely local extractors above the stoves and kitchen equipment, and air intake is provided by a WOLF exhaust system, which is also equipped with a grease filter. Extraction of air from bathrooms is carried out by channel and axial low-noise fans of Soler & Palau firm. The hotel rooms have natural ventilation. Inflow of natural through windows, removal through intrawall channels in bathrooms. Mechanical supply and exhaust ventilation has been designed for the banquet hall, for which two WOLF supply and exhaust units are installed, which are located in the vent chamber. Air supply and removal is carried out from the upper area of the premises by means of square diffusers. To reduce noise and vibration, all ventilation systems are connected to the air ducts through flexible inserts, and sound absorbers are installed on the air ducts. Supply units are equipped with filters; heaters for heating air and air dampers. The scientific part is devoted to the question of air distribution in the pulsating mode by interaction of counter non-coaxial jets. Studies in public buildings show that it is the variable stimuli that have a positive effect on a person’s heat perception. It is the variable mode of flow of inflow jets means the creation of a dynamic microclimate and the actual thermoregulation of the human body is reflected positively. The human can be exposed to a dynamic microclimate in the process of constant stay in natural conditions, and therefore accustomed to constant fluctuations in temperature, humidity and mobility. Hence, it is obvious the feasibility of creating a dynamic microclimate also indoors. At the same time, it is important to know to what extent fluctuations of meteorological factors during the day are necessary and permissible. Study object - "Poseidon" in Mariupol, Donetsk region Scope ofresearch - microclimate support systems, conditions for creating a dynamic microclimate. Goal of research – the design of systems to ensure the microclimate of the hotel, determining the parameters of the dynamic air flow formed by the interaction of counter-mismatched flat jets, when they flow in a pulsating mode and create a dynamic microclimate in the hotel. It is stated that the air flow in the resulting flow is constant, and its components change according to a certain periodic law. This process achieves a change in the direction of the resulting flow from 0 to 1800. Key words - ventilation system, dynamic microclimate, air distribution, flat jets, air flow, flow rate.
