Heat supply. Individual heat point.

The source of the building heat supply is represented by an external heat network from Astana-Teplotransit with the parameters of the heat carrier T1 / T2 = 130-70ºС of heat network of two pipelines ∅133x4.5 mm.

The heat carrier for ventilation and heating systems is prepared at the central heating station (ITP), heat exchanging equipment for maintaining the necessary temperatures of the heat carrier of the heat supply (water) systems are plate heat exchangers and a manifold for distributing the coolant along the directions of the heating system. The Business centre is provided with a hydronic heating system to compensate for heat losses.

Heating system types being installed:

• radiator heating;
• floor heating;
• heating with floor convectors;
• fan coil units;
• fan heaters in the parking lot.

The following items are used as heating devices:

• “GEA” underfloor convectors (Germany);

The heat transfer of the devices is controlled by thermostatic valves RA-N with thermostatic heads of the company "Danfoss" (Denmark), installed on the connections to the devices.

Hot water supply

The hot water supply for the block N1.1 is year-round and has been designed with the usage of the heat exchangers located in the room of the heat point in the N1.1 block.

The "Chiller" system of the "DAIKIN" company is installed in the building of the Business centre in the amount of 2 pieces, the main one and the reserve one.

Two cold supply systems have been provided:

• Cold supply system for air-supply plants;
• Cold supply system of fan coil units.

Directly in the air-conditioned rooms, channel and cassette indoor units with individual wire control consoles are designed. For regulation of cooling capacity of fan coil units, three way valves with bypass are provided. 

The building is provided with supply-exhaust ventilation with a mechanical activation, air heating during the cold season and air cooling during the warm period of the year.

The supply and exhaust system (PV1) N1.1-AHU-L01 serves office spaces 1, 2, 3, 4, 5 levels, as well as part of the basement level. The supply system (P2) N1.1-AHU-L-L01 serves the lobby of the first level.

To ensure and maintain the temperature parameters in the premises, improve the reliability of the systems, save heat, electricity.

Supply and exhaust ventilation system

The HVAC project of the building provides the following supply and supply-exhaust forced ventilation systems of the building:

• AHU1
• AHUPark1
• AHUPark2

The functions of the automated control system of the supply and exhaust system include:

• maintenance of the set temperature of supply or return air
• provision of remote start and stop of the system from the central dispatch center

Water supply and sewerage

• Central urban network from the state corporation "Astana Su Arnasy"
• Internal water supply and sewerage network

Water supply

• A water-measuring unit with a bypass line with ITRON Flodis Ø40 accuracy meter "C" with fixed equipment for remote reading is installed at the water supply inlet.
• Pumping stations for pressure increase and water purification and softening equipment are installed in the pump room.

Hot water supply

Hot water supply is designed from heat exchangers located on the basement floor, in the premises of a heat point.

Sewerage

The project provides for three sewerage systems:

• Economic;
• Drainage;
• Production.

To clean the networks installed revision and cleaning.

2 city lines of 20 kW, reserve DGU 630 kVA, UPS-180 kW

At 0,4 kV voltage, a single busbar system partitioned by an automatic switch into two sections is adopted, with an ABP on a sectional switch.

Electric lighting

The project provides for working, emergency (evacuation) and repair lighting made by LED lamps.

In order to ensure the electrical safety of people and the necessary working conditions for electrical equipment, there are:

• degree of protection of the selected electrical equipment in the relevant category of premises;
• in case of emergency conditions, when the electrical installations are automatically switched off.

Cable trays

A system of cable trays for laying power cables, lighting control cable network and emergency power cables have been installed. 

Electric heating system

The project provides an electric heating system for an entrance ramp (ramp), the main entrance of the lobby, VIP entrance, gutters, pipes on the roof.

The system performs the following functions:

• automatic activation of heating at ambient temperature in the place of installation of the temperature sensor (hereinafter referred to as TS) from -15 ° С .... + 5 ° С;
• automatic shutdown of heating at a temperature outside this range;

System cable structured (SCS). IP-Surveillance System (IP SS)

The UTP CAT7 cable is used in the lines of the telephone system.

In the system, fiber-optic cables use multimode fiber-optic cable between switchboards and the central switchboard.

In the IP-video surveillance system, the UTP CAT7 cable is used. To heat the outdoor observation, a heated cover is used.

Access control system

To limit access to the building or protected premises in accordance with the design of the building, an access control system (ACS) is provided.

The system is designed to ensure the safety of the premises that are important inside the building and where only authorized personnel need to intervene and to monitor the entrances and exits of the building. 

All the doors opening outward in the building can be traced with magnetic contacts.

The system is connected to the information infrastructure.

Fire alarm

A fire alarm system of the type "FPA-5000" manufactured by the company "BOSCH" was installed.

Automatic fire alarm based on the fire panel FPA 5000 provides early detection of a fire at a given facility and provides address signals to engineering systems that ensure the safe location of people in the building in emergency and extreme situations.

The central fire alarm system type FPA-5000 in the event of fire generates signals for:

• inclusion of a fire alarm and evacuation management system;
• disabling general ventilation (exhaust and supply);
• descent of passenger lifts to the 1st floor and their opening.

The system of automatic smoke protection, ensures the safety of evacuation of people from the building's premises, reduces the thermal temperature load on the building's load-bearing structures.

Smoke protection system includes:

• smoke removal fans;
• fire retardant and smoke exhaust valves.

When smoke appears in the smoke areas, fans are started, the fire retardant valves are closed and smoke exhaust valves are opened.
