Change Log Sheet

Reasons for Developing a Section

The design documentation for the contract for overhaul of the RKS No. 6 service buildings was developed on the basis of the agreement No. 232z dated 30.12.2013 and the terms of reference (appendix No. 1 to the agreement No. 232z dated 30.12.2013).

The initial design data are:

- design documentation of adjacent sections ;

- photo fixation of RKS No. 6;

- actual heat loads on the building heating system.

The division is performed in accordance with the norms, rules and standards in force on the territory of the Russian Federation.

The design documentation was developed for the overhaul of the service and production building, located at the address: Moscow, st. Iskra, d. 19.

Description and substantiation of laying methods and design solutions, including solutions for diameters and heat insulation of heat supply pipes from the point of connection to public networks to the capital construction facility

Heat supply of the object is carried out from the existing heat unit. External heating networks are not included in this project.

No action is required on this item.

List of measures to protect pipelines from aggressive impact of soils and groundwater

Due to the absence of external heating networks as part of this project, there is no aggressive effect of soils and soils.

No action is required on this item.

Substantiation of adopted systems and fundamental decisions on heating, ventilation and air conditioning of premises

6.1. Heating

The heating system is single-tube, for the service and production building double-circuit. Each floor has its own independent heating circuit. Heating radiators of floors, in one circuit, are connected in series. Each heating device has an automatic regulator with a bypass

Heating radiators are provided with 3-way temperature controllers, with a control sensor. Depending on the temperature in the room, a large or smaller part of the coolant passes by the heating device along a parallel bypass. This achieves minimum coolant cooling after the first radiator.

For heating rooms of building No. 3 and building No. 4, individual units of program control of coolant temperature PR1 and PR2 are used, which allow to obtain microclimate in these rooms, different from other premises of the facility.

Air removal from the heating system is carried out at the upper points of the system through radiator air vents and ball valves. Water is lowered from the heating system at the lower points of the system through the drain cranes.

6.2. Ventilation

General exchange ventilation with mechanical impulse and heating of air in water calorifers is provided. Plenum ventilation system heaters are equipped with automatic temperature controls of the supplied air.

Air exchanges in the premises are determined in accordance with the requirements of regulatory documents, based on the provision of sanitary and hygienic standards.
