5.5 General description of the bunker air-handling system

Chilled water production for the bunker and the gantry is provided by cooling units installed in technicalroom 118 of the bunker.

Hot water production is obtained by recovery from cooling unit condensers.

The bunker is overpressurized by blowing treated fresh air in each room (output given as an example onthe schematic diagram). The air-handling unit (redundant) is installed in technical air-conditioning roomno. 118.

Thermal loads of rooms are handled by terminal units supplied with chilled water, either fan coil units orair-conditioning cabinets in rooms with high internal thermal additions.

Some rooms are decontaminated following CO2 dusting and anoxic gas leakage by air scavenging andrejection outside, with a time constraint.

5.6 Fresh air-handling

� Fresh air-handling units VCT M01 and VCT M02 supply the entire bunker:

Two units are planned, one redundant in relation to the other. The nominal output of each unit is 5000m3/h. Units are installed in technical room 118.

Each unit mainly comprises:



AIR-CONDITIONING WP



� a pneumatic motor powered flap for suction.� a protection device stopping drops of rain being pulled in from the fresh air intake.� a 90% gravimetric efficiency prefilter.� an 85% opacimetric efficiency filter.� a cold coil, 8 rows, regulated by a two-way valve to obtain the specified dew point.� a protection device against suction of droplets.� a hot coil adjusted by a two-way valve to obtain a neutral variable blowing temperature according to the

outside temperature and internal additions.� a manual isolation flap at the discharge of each unit.� a filter clogging detector, a MAGNEHLIC indicator and a differential pressure switch controlling fan

operation.� A blowing fan with a motor outside the air duct, driven by a dual belt. An electronic variable speed unit

is scheduled for the fan motor to compensate for variations to the loss of head of filters according totheir level of clogging.

� Remote fresh air intake:

At launch time the bunker and gantry rooms located in the rear position must be maintained at anoverpressure. To avoid suction of gas discharged by the launcher, the fresh air intake is located at adistance of 200 m from the launcher. A buried fibro-cement sheath, diameter 1000mm, connects thefresh air intake of the bunker. The remote fresh air intake and the buried sheaths are provided by theMain Structural Work Package.

To compensate for network losses of head, the contractor of this work package installs a helicoidal typefan in room no. 127 of the bunker.

Outside launching campaigns the fresh air of the bunker and the gantry is not from the air intake locatedremotely. The air is taken from the outside close to the bunker and the gantry.

� Fresh air-handling unit VCT M03:

This unit only operates during the launching phase. The air is sucked in the duct connected to the remoteair intake.

The unit output is equal to the sum of the fresh air output from the bunker (5 000 m3/h) and of the freshair output from the gantry (22,000 m3/h).

The unit composition is the same (casing, filters, coils, etc…) as that of units VCT M01 and M02.

However, the fan is installed in the unit upline from the coils.

The unit is connected to the chilled water and hot water networks of the bunker.

The unit is controlled by the programmable controller installed in the air-conditioning control room.

Information at switchover to the launcher launch phase is provided by the CCS.

� Fresh air intake of the bunker:

The fresh air intake is common to the two units. It comprises:

A suction grill made of 316 L stainless steel with an insect-proof net.

A sealed 316 L stainless steel motorized flap. A sheath making up a plenum is connected on one hand to the unit and on the other hand to the remotefresh air intake sheath.

6.5 General description of thermal handling in the gantry

Air-handling units (units, air-conditioning cabinets) are installed in the gantry.

Production of chilled water and hot water supplying equipment installed in the gantry is by means ofcooling units installed in the bunker.

Water links (chilled water and hot water) are by means of connectors locked manually in forward positionand rear position.

Room overpressurizing

Protection against untimely entry of external air and dust is by means of introducing filtered anddehumidified fresh air, which overpressurizes the rooms.

The required overpressure level is indicated for each room in paragraph 6.2

The rates required to ensure room overpressurizing are assessed at the following values:

─ for the integration hall: 1.5 volume per hour, i.e. 18 000 Nm3/h + 2 000 m3/h for the propellant roomscavenging

─ For all other rooms of the gantry: 1.5 volume per hour, i.e. in all 2 050 m3/h.

Fresh air-handling equipment in the integration hall is independent from the fresh air-handling equipmentin technical rooms of the gantry in order to stop air-handling in the hall when the doors are open withoutcausing any unwanted consequences on the overpressure and environmental conditions in other rooms.



AIR-CONDITIONING WP



The Contractor shall schedule the adjustment of the air-handling unit output to the minimum value makingit possible to reach the overpressure levels set in the CCTP. Variable speed units are scheduled for theunit motors.

The fresh air units for technical rooms are redundant.

The fresh air-handling static unit of the integration hall is not redundant. However, redundancy is providedfor by the recycling units.

At VEGA launch time, the fresh air units continue to operate but the fresh air is sucked from an outletlocated 200m from the launcher to prevent the introduction of contaminated air.

Room hygrometric control:

During normal operation, hygrometry is adjusted y dehumidifying the fresh overpressure air.

External air is dehumidified by cooling to drop its weight in water to the following values, according to theoperating rate:

The air is then heated to obtain neutral conditions in relation to the internal temperature conditions.

Exceptionally, during return to nominal conditions after closing the integration hall doors, airdehumidification is carried out by the recycling units.

Room temperature control:

Room environmental temperature adjustment is provided:

─ for the hall: by the air-handling units operating in recycling mode.

─ For other rooms: either by the air-conditioning cabinets or by the fan coil units installed in therooms.

─ In the UDMH and N2O4 propellant rooms:

─ The temperature of these rooms is not specifically treated outside the propellant transfer phases.During the propellant transfer phases, the rooms are scavenged by environmental air from the hall,which is circulated by the propellant extraction system.

─ Air-conditioning equipment is redundant in the RMO room.



AIR-CONDITIONING WP



─ For the integration hall, two units operating in recycling mode are scheduled but redundancy is notplanned.

─ If a unit fails, the overpressure function is provided but temperature and hygrometry control may bedowngraded according to the external climatic conditions and the internal thermal addition.

Safe extraction of propellants

In case of propellant leakage, the air-handling units performing recycling in the room involved are stopped.

Safe extraction is provided by a fan making it possible to set the contaminated room at a 5pa negativepressure in relation to adjacent rooms.

Extraction outlets are located at the bottom part of rooms close to the propellant collection zone.

Compensating fresh air is fed into the room by opening a sealed flap with an outlet to the outside or toadjacent rooms.

The equipment mounted on the safety extraction circuits (grills, sheaths, fans, etc.) are made of 316 Lquality stainless steel.

During the propellant transfer operational phase, the safety extraction system is operational in the UDMHand N2O4 rooms.

6.6 Gantry air-conditioning operating principle

The gantry in forward position is used as the launcher integration building.

The gantry must be maintained at an overpressure and be air-conditioned to maintain the environmentalconditions required for equipment and by personnel.

The gantry air-conditioning equipment is located in the gantry, except for the chilled water and hot waterproduction unit, which is located in the bunker. Chilled water and hot water pipelines from the bunker areconnected manually to the gantry when in forward position.

Before withdrawal of the gantry, the connections between the bunker and the gantry are disassembled.The gantry is moved to the rear position without any action by the personnel. The gantry must bemaintained at overpressure during launching. Fresh air is sucked by an air intake located at 200 m fromthe launcher.

If the water connections to the bunker from the gantry cannot be made, the fresh air units of the gantrycannot dehumidify the air. For this reason, a special unit is provided in the bunker to enable air-handlingof the fresh air of the gantry during this phase.

After launching, the gantry may be manually connected to the chilled water and hot water pipelines of thebunker located in rear position, and the air-conditioning of the gantry can operate normally as in theforward position.

automatic adjustable type, TROX make type R or similar.� diffusion grills installed in vertical partitions of rooms.� fresh air sheaths must not cross propellant rooms.

6.7.2 Integration Hall air-handling

There are two distinct operating modes in the hall:

� Normal operation:

The air diffusion principle in the integration hall is similar to that implemented in existing buildings (gantryof the ELA2 firing pad and in the BAF).

Two units blow recycled air in the top part of the gantry under the travelling crane. Air distribution is bydiffusers with a high induction rate to limit temperature deviations and air stratification.

The diffusion system by induction shall be approved by the organization CETIAT.

The maximum temperature difference is 1.5 °C between the ground and a height of 20 m.

The exhaust air is sucked by the units in the bottom part of the gantry. The fresh air providing theoverpressure is mixed with exhaust air upline from the air-handling units

The total recycling output is 60 000 m3/h (5 volumes per hour).

During normal operation, the coils must cool the environmental air without dehumidification, The coils arethen supplied with water chilled to 10°C maximum. The 10°C temperature is obtained using water chilledto 6°C by mixing using recirculation pumps (see hydraulic schematic diagram).



AIR-CONDITIONING WP



During prolonged downtime, the economic operating conditions are obtained using the following principle:

– the fresh air-handling units are kept operating. Fresh air is dehumidified and reheated to obtainthe required hygrometric-thermal conditions

– only one of the two air recycling units of the environmental air operates. The other one isstopped.

� Return to nominal conditions:

After the doors are opened, the external air fills the hall. The units must enable return to nominalenvironmental conditions within 2 hours maximum.

The cold coils are fed with 6°C chilled water. The dehumidification capacity of the units is increased byreducing by two the recycling output by operating the motor variable speed unit. A hot coil is scheduleddownline from the cold coil to prevent the temperature of the blown air from dropping under theenvironmental dew point.

After returning to the required hygrometric conditions, the unit operates in normal mode to return theenvironmental air to the set point value.

Note:

The composition of units, the operating principle described and sizing and power provided in this file arefor reference purposes. The contractor is free to propose any other principle to obtain the expectedfunctions.
