Koreiz, Alupkinskoe highway, 9 was developed in accordance with the terms of the contract and the Terms of Reference for the implementation of project documentation, in accordance with the requirements of SNiP II-35-75 "Boiler installations" with the manual to SNiP II-35-75 "Recommendations for the design of roof, built-in and DBN 32.5.20-2001 "Gas supply” and with the "Rules for the design and safe operation of steam boilers with a steam pressure of not more than 0.07 MPa (0.7 kgf/cm2), hot water boilers and water heaters with a water heating temperature of not more than 115 ° C. 1.2 Justification of the project content The project documentation was completed to the extent prescribed by Resolution No. 87 of February 16, 2008: "Regulations on the composition of sections of project documentation and requirements for their content" 2 Information about the climatic and meteorological conditions of the construction area, the calculated parameters of the outdoor air The construction area is the Russian Federation, Yalta. The calculated parameters of the outdoor air are accepted according to SP 131.13330.2020: - the estimated temperature of the cold season is minus 4 °C (parameter B); - the estimated temperature of the warm season in accordance with the design assignment for the design of air conditioning is assumed to be plus 34 °With - estimated wind speed in points for January is 2.8 m/s; - the average temperature of the heating period is plus 5.3 °C.; - the duration of the heating period is 127 days; - the average outdoor temperature of the heating period is plus 5.3 °C. The estimated indoor air temperature is plus 16-22 °C. 3 Information about sources of heat supply, parameters of heat carriers of heating and ventilation systems The source of heat supply for heating systems, hot water, heat supply for ventilation units and fan coils of the hotel is a projected, freestanding boiler room. Parameters of the heating network at the entrance to the hotel building - The scheme of heating networks is two—pipe - Heat supply scheme — closed dependent - Temperature chart of the heating network — 95/70 °C - The heat carrier is water The coolant of heating systems is water with a temperature of plus 80/60 °C, heat supply systems for ventilation systems, water heating technology for the bath zone is water with a temperature of plus 95/70 °C. 4 Description and justification of laying methods and design solutions, including solutions regarding the diameters and thermal insulation of heating pipes from the point of connection to public networks to the capital construction facility For solutions on heating networks, see volume DPM-22-809- LATER. The heat supply system is 2-pipe closed. The laying method is underground ductless with laying in steel pipe cases under the driveways. The pipelines are designed in steel with polyurethane foam thermal insulation according to GOST 30732-2020. Connect the pipelines in the boiler room locally. The heating network is designed with a slope of at least 0.002. Disconnecting valves are provided on the branches of the heating network with installation of fittings for pressure gauges and thermometers. Fittings are installed on the heating network at the highest points for air release, at the lowest points for water discharge. Water is drained from the heating network into the wet (discharge) well DK1 from the boiler room, from where it is removed by a portable pump into the storm sewer. Compensation of thermal elongation of pipelines is carried out due to the angles of rotation and axial bellows compensators. The project uses fixed shield supports, according to the guidelines for duct-free pipe laying in PU insulation. Compensation cushions should be provided at the angles of rotation of pipelines to reduce pipe friction against the ground. Gas-tight devices are provided on pipelines and at the intersection of building structures. In case of channelless laying of pipelines, the bottom of the trench must be lined with sand without stones and have a thickness of 150 mm, with mandatory subsequent sealing. The sand around the pipes is important not only to protect them, but also to provide friction between it and the outer shells of the pipes, which limits their expansion. When backfilling pipelines, it is necessary to install a protective layer of sand that does not contain solid inclusions. A marking tape must be placed on a layer of sand above each pipe. 5 List of measures to protect pipelines from the aggressive effects of soils and groundwater The projected pipelines do not come into contact with soils and groundwater solutions for pipelines of thermal networks see volume of the PDM-22-809- LATER. Protection of the outer surface of steel pipes from corrosion is not required due to the use of factory-made pipelines in polyurethane foam (waterproof layer) thermal insulation in the project (ODK system is provided). 6 Substantiation of the adopted systems and fundamental decisions on heating, ventilation and air conditioning of premises with the application of calculating the total release of chemicals into the indoor air, taking into account the joint use of building materials used in the projected capital construction facility, in accordance with the methodology approved by the Ministry of Construction and Housing and Communal Services of the Russian Federation The materials used in the project have expert opinions and certificates of compliance with their safe use for humans. The amount of harmful substances that may be released from them into the indoor air will not exceed the maximum permissible concentration (MPC) and will not have a negative impact on human health. The calculation of harmful emissions can be downloaded here. 7 Substantiation of the energy efficiency of structural and engineering solutions used in heating, ventilation and air conditioning systems of premises, heating networks The building provides combined water heating systems with horizontal floor layout, dead-end movement of the coolant, collector wiring in the room and underfloor heating in the bathroom area. The floor–to-floor wiring of pipelines is carried out openly on the walls, in the rooms of offices, office, technical rooms, hidden in the floor in the room stock, in public areas - hidden in the floor and in the wall.
