Heating, ventilation and air conditioning
General part
This Explanatory Note considers the provision of heating, ventilation and air conditioning to a commercial and commercial complex with an underground parking lot, located in the Northern Administrative District of Moscow at the address: ul. Butyrskaya, house 77.
The building, which houses the commercial and commercial complex, consists of underground and ground parts.
In the ground 12 storey part of the building there are :
On the 1st floor there is a store trading room, a cafe with auxiliary rooms, entrance groups and technical rooms.
On the 2nd floor, on the elev. 2.400 an entrance group of the office part is organized, including a passage/waiting area, an access control system, a pass office, a hall and a buffet at 29 seats. The shopping and office parts of the building have independent entrances from the street and evacuation exits. At elevation 2.400 there is a dining room for office employees at 50 seats. The dining room operates on semi-finished products of a high degree of readiness. At el. + 0.000 a cafe for 25 seats is designed, which has a separate entrance. It is also assumed that the dining room, buffet and cafes at elevation + 0.000 are served by one operator and therefore have single technological rooms .
Floors from 3-12 are intended for office space.
On the roof in axes "B" "K," "6" - "7," the project provides for the organization of an autonomous gas boiler room of the roof type.
Underground parking consists of two separated parking lots located under each other. Entrance to the first parking lot located at elev. -4.650, -7.950 is carried out along the ramp from elevation - 0.700. The second parking is located at elevation 11.250, which is accessed using a car lift, which is located at el. -1.800. Underground parking is connected to the above-ground part of the building by means of 2 elevators with a carrying capacity of 1000 kg, which go to elev. 2.400. One of the elevators, in addition to the usual functions, is designed for transportation of fire departments. The office part is served by two panoramic elevators located in the atrium and one service closed elevator, also intended for transportation of fire departments. The project also provides for 2 evacuation stairs, one of which has access directly to the street, the second through the lobby to the street .
The building has independent fire compartments:
- 3rd floor (elev. -11.250) - passenger car storage rooms with fire compartment area not exceeding 3000 m2;
-2 and -1 floors (elev. -7.950 and -4.650) - car storage rooms with fire compartment area not exceeding 3000 m2;
ground floors - a complex building with a floor area of about 1300 m2, representing one fire compartment.

1.1.5 Design factors for determination of cold consumption in rooms
To create comfortable conditions in the premises, the cold consumption is determined based on the calculation of assimilation of heat supplied to the premises:
- from working people;
- from process equipment and organizational equipment that consumes electricity;
- from solar radiation;
- from artificial lighting;
- with external plenum air.
Heat source
A gas roof boiler house is designed for heating, ventilation and air conditioning systems. For details, see the special. sections.
Source of cold
To provide cold air conditioning systems, a refrigeration center is designed with the installation of 2 refrigeration machines (chillers).
One of the chillers is proposed to be installed with two air-cooled remote condensers.
Another chiller is proposed to be installed with two remote condensers with "dry" (ethylene glycol) cooling.
Cold consumers are:
- air coolers of air conditioners;
- zone fan heat exchangers (fencoyles).
Coolant for air conditioning systems and fenkoil accepted water with temperatures of 712 wasps.
Remote condenser plants with "dry" cooling are used to ensure cold supply of fencoyles in the winter period of the year, which allows using natural cold outside air. For this purpose installation of the heat exchanger cooling the water (712 wasps) circulating in a system with the intermediate heat carrier - 40%nym by ethylene glycol solution with temperatures of 611 wasps is provided in the system of cold supply.
In the warm period of the year, a heat exchanger can be installed in the circulation ethylene glycol circuit (chiller - "dry" cooler) in order to obtain hot water for the HVA system.
To equalize the operation of the refrigerating machine at low loads, a storage tank is provided.
1.1.8 Noise level
The design provides solutions that ensure noise level in the premises that does not exceed the permissible values for heating and ventilation systems:
- in working rooms and rooms - 50 dBa;
- in rooms - 45 dBa;
- in technical rooms - 60 dBa.
Heating and heating of air heaters
Heating and heating systems
To calculate the heat load of the heating system, the following heat transfer resistance factors were adopted by the external enclosing structures: (according to the data of the section "Energy Efficiency "):
for walls - 3.3 (sq.m * OS) / W;
for a covering - 3.55 (sq.m * OS) / W;
for overlapping over the parking - 2.29 (sq.m * OS) / W;
for overlapping over journey - 3.09 (sq.m * OS) / W;
for glazing - 0.56 (sq.m * OS) / W.
The building heating and heat supply systems of the air heaters of the plenum plants and air conditioners are connected to the designed roof boiler room according to a dependent scheme. The coolant of heating and heat supply systems of air heaters of plenum plants and air conditioners (to calculate the heating surface) is water with temperatures of 9570 ° С.
Building heating systems with local heating devices are assumed:
in the premises of the above-ground left part of the building and the above-ground part of the building from 3 to 12 floors - two-pipe vertical, with upper wiring of the supply line. Water supply to side heating devices with coolant circulation by "superuvniz" device. It is proposed to use steel compact radiators (or convectors) of import or domestic production as heating devices;
for cafe and store premises - double-tube horizontal-vertical, with floor-by-floor wiring of supply and return pipelines to heating devices. Water supply to lower or side heating devices with coolant circulation by "superuvniz" device. Horizontal branch riser pipelines are laid in floor structures of the corresponding floor. It is proposed to use steel compact radiators (or convectors) of import or domestic production as heating devices;
in underground parking areas - two-tube horizontal, with floor-by-floor wiring of supply and return pipelines to heating devices. It is proposed to use registers made of smooth pipes as heating devices. The heating system maintains air temperature in the storage area of cars plus 5 wasps.
To control heat transfer, almost every device is equipped with a temperature controller that allows changing the heating power levels of the radiator, thereby creating comfortable conditions for individual rooms or zones. To equalize the water pressure in the system, balancing valves are installed on the riser branches.
Heating devices to the risers are connected through shut-off valves (valves) designed to disconnect individual devices from the system, empty them and fill them with water without disconnecting the entire system.
Above the central entrance to the building and above the entrance to the underground parking lot, the installation of air-heat curtains with electric heating is provided.
Air-heat curtains are delivered complete, with automation and control devices.
Pipelines of heating, heat supply and cold supply systems
Pipelines of the above systems are made of steel water and gas pipes according to GOST 326275 * with a diameter of up to 57 mm and steel electric welded pipes according to GOST 1070491 with a pipe diameter of more than 57 mm, as well as bent sections and points of reinforcement connection.
Pipelines of horizontal branch-risers of heating systems laid in floor structures shall be made of metal-plastic pipes in protective corrugated pipes ("foot" type). At the same time, the offered temperatures of the heat carrier of 9570 wasps, at design engineering are required specifications.
All pipelines of cold supply systems of air coolers and fencoyles, heat supply systems of air heaters, main pipelines of heating system, pipelines laid in underground channels and at external doors, main risers of heating system are heat insulated by Armaflex pipe insulation material of Armstrong or Thermaflex company.
