1.4.3 Closed Loop Rack based cooling system

The Data center should be equipped with Liquid Cooling System; it is an air/water heat

exchanger to remove high levels of waste heat from server enclosures and to provide

uniform, effective, affordable cooling for Servers and similar IT equipment (switches etc)

installed in server enclosures. Each liquid cooling system should be a closed unit

consisting of a cooling system and cool either one or two server enclosures.

1.4.4 High Performance Liquid Cooling Package – Closed Loop Cooling.

CLC Rack CW should offer enclosure-based cooling separate from the room air and is

thus also able to reduce the noise level. The unit should be capable of providing cooling

9

for either one or two server racks. The hot server air should be drawn off to the rear of

the server rack. After cooling, it should be expelled at the rear of the rack and is thus

made available to the IT equipment once more.

Unit should be connected to the piping system of chilled water or anti-freeze mixture. It is

suitable for the free-cooling systems because allows warmer water usage. The surface

temperature of the heat exchanger is controlled by valve, which fluently modifies the

cooling capacity in accordance to the actual demand. Variable speed fans help to keep

always the correct airflow for all IT equipment in data center. EC motor technology used

in the fans markedly reduces the annual power consumption.

Both top and bottom connection of the unit is available.

The air-conditioning unit’s design has to be fully compatible to bystanders IT racks from

the perspective of dimensions, material, color, and mechanical coupling elements. The unit

in the row of the cabinets has to enable an installation of cable management, roof

elements, aisle doors etc.

1.5 Air-Conditioning

Air-conditioning unit includes:

- Highly efficient water heat exchanger made of copper pipes and aluminum fins

with a special surface. The oblique position of HX enlarges the surface, and

optimizes the heat transfer.

- Three stacked air filters of filtration class G4 in combustible finish for ecological

disposal. The frame is ready for easy maintenance and filter replacement.

- Five or more hot-swap radial fans with EC motors significantly reducing the

power consumption with fluent speed change and operation feedback to the

control system.

- Controller with software for independent control of all components, running also

in case of interruption of communication between units or central display.

- Minimum Four temperature sensors located in the front and rear side

monitoring the air temperature in the upper and lower part of the space.

Sensors could be calibrated from controller. Controller enables to change the

logic between average and maximal values, and arranges substitutability in case

of failure.

- Two humidity sensors located at the bottom of front and rear part of the unit

for precise monitoring of the room conditions.

- Air-conditioning unit, with “D” in the type code, includes color touch screen in

the front door. 4.3” large display is equipped with special software for

monitoring and control of up to 10 units. It enables communication through

TCP/IP protocol, remote control via Ethernet and implemented webserver, and

10

easy SW upgrading and data downloading via USB disk or SD card. Another

function implementation is possible on special request.

Functions:

- The basic task is to cool down the air from the hot zone of datacenter and

distribute it to the cold zone in front of the IT equipment. The unit is designed

to keep the constant temperature in both zones thanks to the water valve

adjustment and variable fan speed.

- If the humidity in the hot zone is within the limits set by an administrator, then

the unit’s internal logic tries to avoid any condensation of the air moisture,

maximize the cooling efficiency, and minimize influence on the humidity climate

of the room.

- If the measured air humidity is above the set point, then the unit is

automatically switched to the dehumidification mode, and actively supports the

surface condensation to decrease the humidity in the room. The resulted

condensate is discharged to the drainage.

- The unit can be equipped by integrated steam humidifier which increases the

room humidity to the set point.

- Units could be connected to bigger groups under a superior control with

advanced control logic (sequencing, team working, overload start, etc.)

5.3 Very Early Smoke Detection and Alarm [VESDA] SYSTEM

5.3.1 Introduction:

The VESDA is a programmable, intelligent controlled, self-contained air sampling smoke

detector. The VESDA or the very early smoke detection system that provides the highest

sensitivity appropriate for detecting a complete range of smoke particles produced in

incipient stage and real fires involving natural or synthetic materials. It comprises of an

air sampling system, filter assembly, aspiration system, detector and control system.

5.3.2 Design:

The VESDA uses a unique technology, an intense broadband light source (XENON Strobe

Light) in order to closely emulate the spectrum and intensity of sunlight itself. The

system has a photoelectric receiver which is used to gather the scattered light having a

18

broadband spectrum. This broadband spectra response makes the detector respond to all

particle sizes. The smoke particles produced during real or incipient fire shall depend on

the fuels involved and combustion temperatures. Thus a broadband spectrum method of

detection performs well for a complete range of fuels and through the process of fire.

The VESDA system is protecting the Server of the DC with very early warning of smoke

detection and alarm. The air sampling is done in all the three voids of the Server room

and the Network room i.e., below the false floor, room void and above the false ceiling.

This gives very early warning in case of fire in any of these three voids.

5.3.3 Principle of Operation:

The aspirator draws the air from the protected areas through the air-sampling network,

through the multi stage filter assembly to screen out the large airborne dust particles and

through the specially constructed detector head where it is exposed to a broadband

spectrum of light. Light scattered by the particles pass through a series of optical

components to an extremely sensitive solid-state light receiver. The receiver converts

the light energy into an electronic signal representing the level of smoke in the air sample.

The receiver sends this signal to a microprocessor where it is processed and presented on

the bar graph display as one of many lighted segments. This activates the alarm indication

when appropriate.

7.0 Services Level Agreement (SLA) & Warranty

The Supplier warrants that all the goods are new, unused, and of the most recent

or current models, and that they incorporate all recent improvements in design and

materials, unless provided otherwise in the Contract.

The bidder has to ensure that the solution proposed delivers an uptime guarantee

of 99% of the entire system on a yearly basis. For every extra day of downtime

above 1%, the warranty should be extended by twice that duration. In the event of

failure of any of the sub-systems or components of the proposed solution, the

bidder has to ensure that the defects are rectified within two full working days. All

these conditions need to be satisfied. During the warranty period, vendor will have

to undertake comprehensive maintenance of the entire equipment and accessories

supplied by the vendor at the place of installation of the equipment.

The defects, if any, during the guarantee/warranty period are to be rectified free of

charge by arranging free replacement wherever necessary.
