The detailed design is intended to increase the energy efficiency of the centralized heating system of consumers by reconstructing the main heating networks from the boiler house "Gigant" on the section TK-136 - TK-114, which are characterized by high rates of heat loss and unsatisfactory technical condition.

The detailed design is intended to increase the energy efficiency of the centralized heating system of consumers by reconstructing the main heating networks from the boiler house "Gigant" on the section TK-136 - TK-114, which are characterized by high rates of heat loss and unsatisfactory technical condition. Additional grounding is not required. When performing work on the reconstruction of old external heating networks, it is planned to: - replace existing pipelines of external heating networks using a previously thermally insulated pipeline with polyurethane foam with a conductive steel pipe and an outer shell made of polyethylene resistant to atmospheric corrosion (according to DSTU B V.2.5-31:2007); - replace existing pipelines in thermal chambers using a steel pipe according to DSTU 8943:2019 with thermal insulation from mineral wool mats with a covering layer of foil insulation; - replace the existing one and install a new one shut-off valves, compensators in
heat chambers;
-
thermal insulation of pipelines and valves in heat chambers;
-
repair and reconstruction of heat chambers, arrangement of drainage wells and
pits;
-
partial replacement of impassable channels (precast concrete trays);
-
implementation of a system for remote control and monitoring of heat network pipelines (SDKM) with installation of control devices;
-
restoration of
road
surface
and
sidewalks
in
places of
laying
pipelines of external heat networks;
- performance of works on landscaping and improvement of the territory.
According to the results of engineering and geodetic surveys, the diameters of existing steel
pipelines laid in channels from TK-136 to TK-114 make up Du 500.
Temperature graph – 115-70⁰С.
Limited design pressure in the heating network – P=1.6 MPa.
Consumers connected to the designed network in terms of heat supply reliability
are in the second category.

Operation mode of the centralized heating system – seasonal, only for heating needs (without hot water supply - DHW). The surrounding development is represented by a complex of non-residential and residential buildings. The territory under consideration has existing landscaping and landscaping. The relief of the territory under consideration is planned in accordance with the planning of the adjacent territory.
