Abstract: Kuz V.I., Shapoval S. P. (supervisor). Microclimate support systems in the hotel "Edem Hotel" in Hrybivka, Odesa region. Master’s thesis. - Lviv Polytechnic National University, Lviv, 2020. Extended abstract. In this master’s qualification work, a project of a seven-storey hotel complex, located in Hrybivka, Odessa region were designed. The source of heat supply is the roof boiler room. The heating system of the building is a horizontal two-pipe system with the upper distribution of pipelines with a common heat metering unit, which is located in the roof boiler room. Korado steel panel radiators of the Radik CVK 60/70/90 type with the built-in thermostatic valves and Radik LVK 20 with the built-in valves with preliminary adjustment are accepted by heaters. The ventilation system of hotel rooms is designed as mechanical supply and exhaust system , as well as separate groups of supply and exhaust ventilation systems were designed for independently serving of different types of premises. The supplying air is heated in water heaters. All air supplying systems gives air to the upper zone. From the premises of the bathrooms, the project provides for separate exhaust systems, which are connected to the internal wall duct using axial domestic duct fans. Exhaust boxes to deduce above a roof ridge on 0,5 m. The scientific part of the master’s thesis reveals the use of flat and vacuum solar collectors for water heating in the hotel industry. The use of solar energy to heat water is one of the oldest examples of the experience of using alternative sources. Modern solar collectors convert the energy of the sun’s rays into heat that heats the water in the storage tank. The performance of solar collectors depends on the area of the solar field, which is determined either by the number of vacuum tubes or the area of the flat collector, and also depends on the correct location of the solar system. Vacuum tube collectors, having a cylindrical shape of the tube surface, give more heat than flat collectors, because it depends less on the angle of incidence of sunlight on the plane of the collector. Vacuum tube collectors also have a higher efficiency because they are structurally better for thermal insulation. Manufacturers of heat engineering equipment, including solar collectors, are still searching more and more sophisticated solutions to simplify the equipment schemes of solar systems, increase the reliability and safety of their use. Both vacuum tube and flat solar collectors have their own features and advantages in application, different performance. If sun-heated water is needed in the summer at the cottage, in a boarding house, or in a restaurant, it is best to install a thermosiphon solar system, which works best in the summer. Flat collectors are more used for year-round operation complete with already installed heating equipment. They can be used as stand-alone water heating systems or in conjunction with existing appliances for heating and hot water supply of a house or building. Solar collectors are often used successfully to heat pool water. Study object - hotel "Edem Hotel" in Hrybivka, Odesa region Scope ofresearch - microclimate support systems, solar collectors. Goal of research - design of systems to ensure the microclimate of the hotel premises using different versions of solar systems - both flat and vacuum solar collectors. In this case, both systems (flat solar collector and vacuum collector) are acceptable, but each has its drawback. The flat solar collector has a good efficiency indicator, but the modular vacuum collector has an opportunity to manipulate the area of a heliofield, with small expenses of space. For this master’s qualification work, flat solar collectors of the company BAXI SB 20 + V were chosen, due to its cheapness, compared to the modular vacuum collector, and acceptable thermal performance. Key words: microclimate, hot water supply, solar system, vacuum collector, flat collector.
