The exit from the CTP is provided directly to the outside. The foundation for the CTP building is a monolithic reinforced concrete slab 100 mm thick, for concrete preparation 0,90 mm. The load-bearing and enclosing structures of the central heating substation have a fire resistance limit of 3 h, the limit of flame propagation along the structure is equal to zero, and the ceiling of the central heating substation is made of materials of the NG group (non-combustible). Enclosing and structural materials have a technical certificate and a hygienic and fire safety certificate of compliance with the requirements of Russian norms and standards. The main architectural and design solutions are presented in the drawings of the AS brand (Volume XNUMX of the project).

Thermal mechanical solutions. layout solutions. Description of the thermal scheme of the CHP.

In accordance with the Design Assignment, the CHP provides for the use of pumps from the "WHO" company (Germany), collapsible plate heat exchangers from the Alfa Laval company (Russia). All imported materials and equipment are certified for use in Russia (see attachments). The circulation of the coolant in the primary circuit of the heating system is carried out by pumps "WHO" TOP-S 65/13 3 ~ PN6/10 (working + reserve) - pos. K1, K2. The circulation of the heat carrier in the primary circuit of the DHW system is carried out by pumps "WHO" TOP-S 40/10 3~ PN6/10 (working + reserve) - pos. KZ, K4. Heating system - independent through plate-type collapsible heat exchangers, 100% load for each - pos. K13 - K14. DHW system - independent through plate-type collapsible heat exchangers, 100% of the maximum hourly load for each - pos. K15, K16. The temperature of the heat carrier is controlled by a three-way control valve from the company "ESBE" (Sweden), installed on the primary circuit, depending on the outside temperature - pos. 41. The circulation of the coolant in the secondary circuit of the heating system is provided by pumps "WHO" IPL 40/130-2,2/2 (working + backup) - pos. K5, Kb. The circulation of the heat carrier in the secondary circuit of the DHW system is provided by pumps with frequency regulation "WHO" MVI 102/PN16 3~ (working + standby) - pos. K7, K8. To maintain the required volume of water in the heating and hot water system caused by the possibility of leaks, the project provides for automatic make-up from the water supply. Primary filling of equipment and pipelines is provided with prepared water. The supply of cold water to the central heating station for the preparation of hot water, make-up and filling of heat supply systems is supposed to be through two inputs from the water utility networks, in accordance with the issued technical specifications. To compensate for the thermal expansion of water: - 2 expansion tanks Flexcon CE 1000 from "Flamco" (Netherlands) with a capacity of 1000 liters. - pos. K19, K20. - the installation of an expansion tank AFE CE 150 from Cimm (Italy) with a capacity of 150 liters is provided for in the DHW system. - pos. K22. - To increase and maintain the required pressure in the make-up system on the cold water supply system, the following is installed: - Boosting station of the company "WHO" MHIE 205-2G - pos. K9, K10 for feeding the heating system. The placement of equipment and piping are made in such a way as to provide the necessary passages for maintenance, installation and dismantling of equipment, in accordance with the passports and operating instructions for the equipment used (the central heating unit operates in automatic mode without the constant presence of maintenance personnel). The main thermal and mechanical solutions are presented in the drawings of the TM brand (Volume 4 of the project).

Construction organization project

The organization of construction production must ensure compliance with the technology for the production of construction and installation works, the implementation of technical solutions, as well as the use of materials and products that have the appropriate certificates and permission from Rostekhnadzor of the Russian Federation. As part of the POS, a construction master plan was developed for the main construction period on a scale of 1:500. On the construction plan are indicated: - the projected building of the central heating station; - location of temporary buildings and structures; - the place of installation of the truck crane; - platform for washing wheels; - places of placement of household and construction waste; - places of storage of materials and products; - points of connection of temporary engineering networks to meet the needs of construction; - fencing of the construction site. An on-site warehouse for the storage of metal structures, lumber and other building materials is organized in the form of an open area. The stock of building materials at the facility is taken in the amount of a three-day consumption volume. For the entry and exit of vehicles from the construction site, gates with a width of at least 4,5 m are installed. The facility is supplied with electricity and water for the period of reconstruction from existing networks. For firefighting purposes, a fire hydrant is used, which is installed before the start of construction of the facility on the existing water supply line. A temporary household town is arranged on the territory of the construction site. The location of the temporary amenity camp is shown on the construction plan. The construction site is equipped with a set of primary fire extinguishing equipment - sand, shovels, hooks, fire extinguishers. Dry closet cabins are installed in the immediate vicinity of the work sites. The installation location is indicated on the building plan. Small debris and dry dusty residues of materials are collected in dust-tight bags (kraft, polyethylene) and manually immersed in a waste bin that ensures minimal dusting of the environment. The construction site is equipped with the necessary safety signs and information boards. To wash the wheels of cars at the exit from the construction site, a wheel wash is organized. Carry out washing with a closed water cycle. Provide devices for separating solid sludge with its subsequent removal to a waste disposal site. Quality management of construction and installation works should be carried out by a construction organization and other organizations supervising construction and will include a set of measures, methods and means aimed at ensuring that the quality of construction and installation works and completed construction projects comply with the requirements of regulatory and project documentation. The quality control system for construction and installation works must be maintained in accordance with the requirements of SNiP 42-01-2002.
