- diameter over 57 mm - from electric welded pipes as per GOST 1070491, p. 10.

The main heat and cold pipelines are insulated by KAIMANNFLEX foam pipes.

Cold supply

To provide "cold" air conditioning systems at the specially equipped site, the installation of the all-in-one unit of the type "Matrix" SBS 040 LIEBERT - HIROSS (supplier of LLC "ITC Konven") was designed;

The " Matrix" type unit (water cooling machine) is equipped with two separate compressor cooling units, including a screw compressor, an evaporator, a condenser, a common hydraulic module and a circuit of natural cooling of the coolant.

Cooling capacity of the unit is 389 kW.

This refrigerating machine prepares a water glycol mixture with a 40% ethylene glycol content at a temperature of 712 ° C.

The presence of free cooling circuits allows using the ambient temperature to cool the water glycol mixture in the cold period of the year without starting the compressors of the refrigeration complex, which saves electricity.

Air cooling condenser consists of heat exchanger and fans with fan motor speed controller.

- Hydraulic module includes main and standby pump, buffer tank.

Cooling medium natural cooling circuit consists of additional heat exchanger and three-way valve. The refrigerating machine switches to the natural cooling mode when the street air temperature decreases below + 10 ° C, while the fans and the pump continue to operate without the compressors.

Each compressor refrigeration unit operates according to a freon refrigeration cycle with step-by-step adjustment of cooling capacity.

Cooling machines in base have frame, on which compressors, condensers, evaporator, pumps, circuit of natural cooling of coolant, pipeline piping systems and control board are mounted.

To provide conditioners of D1 D2 conditioners with water 10/15 ° С, the installation of a mixing unit equipped with a pump, a three-way valve, a filter and an automation panel was designed.

Cold Supply Automation and Instrumentation

The supply of refrigeration machines includes an automation and electrics system, which allows you to automatically maintain the temperature of the water glycol mixture 5/110 °.

Also, in automatic mode, depending on the ambient air temperature, the refrigerator is turned on or the free cooling function is used.

Ventilation and air conditioning

In order to create an air environment in the designed rooms that meets hygienic standards and technological requirements, it is envisaged to use designed supply and supply air conditioning systems, general and local mechanical ventilation.

Air exchanges for rooms are determined by calculation, sanitary standards and by cleanliness class are given in Table 2.9.1:

The air exchange of the designed industrial and administrative-household premises is determined by the calculation for ensuring the required air purity, assimilation of heat inputs, as well as by the standard multiplicity.

The volume of air supplied to clean rooms to maintain the specified purity class is determined by the multiplicity of air exchange according to GOST R ISO 1464412000.

To ensure the required parameters of the air environment, in the rooms of class 100000 (P8) and 10000 (P7), centralized air conditioning is provided, consisting of outdoor air conditioning systems, recirculation systems (finishers) of clean rooms (rooms) and exhaust units.

Outdoor air conditioning system P1 is designed for outdoor air treatment and its supply to the room.

Air conditioner for outdoor air treatment is straight-through; its productivity is determined based on the condition of providing compensation for the volumes of air removed from the premises by local suction, together with exhaust units, and creating an overpressure in clean rooms that prevents air from flowing from rooms with a low purity class to a higher one .

Air conditioner consists of pre-filter of G4 type, recuperator with intermediate heat carrier, 2-stage surface air cooler, air heater of second heating, centrifugal fan with guide vanes and electric motor, secondary filter of F9 type, noise absorbers at inlet and outlet and valves with electric drive.

Further, along the air duct route (up to the first branch), there is an installation of steam distribution pipes designed to treat supply air with steam from steam generators.

The air treatment process in the air conditioner of the P1 system is shown in drawing N1.

Treated plenum air is supplied through air ducts to ultra-fine air purification filters installed in the ceiling and upper areas of the walls and enters a clean room.

To ensure the required cleanliness class, as well as to remove heat losses, there is an installation of conditioners-conditioners of recirculation systems D1 and D2. Recirculation systems of clean rooms (rooms) are designed for final treatment of air (cooling, heating) supplied to clean rooms (rooms) and maintenance of specified parameters of air medium in them. The conditioner consists of a pre-filter type F5, an air cooler, a centrifugal fan with an inverter and an electric motor, noise silencers and electrically driven valves.

Air taken from the room, after treatment in conditioners-finishers of recirculation systems, is supplied through air ducts to ultra-fine air purification filters installed in the ceiling and upper areas of the walls and is supplied to a clean room. From clean rooms, recirculating air from the lower area of the room is returned to the conditioner through the protective filter through the air ducts.

The process of air treatment in air conditioners and finishers of systems D1 and D2 is shown in drawing N2.

Exhaust units are equipped with fan inverters controlled by the automation system from differential pressure sensors and serve to maintain the specified air pressure in clean rooms. Exhaust plant consists of pre-filter of F5 type, noise absorber, centrifugal fan with electric motor, and valves with electric drive.

Designed air ducts for general ventilation systems of floor rooms are made of hot galvanized galvanized steel as per GOST 1491880 * with thickness as per SNiP 41.012003 .

In the production rooms at workplaces in order to localize harmful emissions, local suction pumps are provided with mechanical inducement from process equipment, connected to local exhaust ventilation systems.

The designed ventilation equipment is located at elev. 0.000 and 3.200 in designed ventilation chambers.

Explosive and

fire safety measures

The project envisages fire prevention of heating and ventilation systems in accordance with the requirements of SNiP 41.01-2003

In case of fire, all ventilation systems are disconnected.

And smoke removal systems are turned on.

All equipment is grounded.

Noise reduction measures

According to SNiP II1277, to reduce noise from operating ventilation plants to values not exceeding the permissible levels of sound pressure at workplaces, the design provides for the following measures:

ventilation equipment is located in rooms, the enclosing structures of which have protection against noise penetration from these rooms into neighboring ones;

plenum and exhaust plants have built-in noise silencers;

- fans with electric motors are installed on vibration bases and separated from air ducts by soft inserts;

air speeds in air ducts and air distributors, peripheral fan speeds are adopted taking into account ensuring optimal acoustic qualities of the designed systems;

Automation of heating and ventilation systems

To ensure and maintain the required air conditions in the premises, increase the reliability of the systems, save heat, electricity, as well as reduce maintenance personnel, the project provides for the following measures:

local monitoring of indoor air parameters and heat and coolant parameters;

protection of calorifers from freezing;

local and remote control of ventilation systems;

control of supply air temperature and humidity;

disconnection of all ventilation systems in case of fire.
