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 ITequipment once more.

Unit should be connected to the piping system of chilled water or anti-freeze mixture. It issuitable for the free-cooling systems because allows warmer water usage. The surfacetemperature of the heat exchanger is controlled by valve, which fluently modifies the coolingcapacity in accordance to the actual demand. Variable speed fans help to keep always thecorrect airflow for all IT equipment in data center. EC motor technology used in the fansmarkedly 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 theperspective of dimensions, material, color, and mechanical coupling elements.

8

- Five or more hot-swap radial fans with EC motors significantly reducing thepower consumption with fluent speed change and operation feedback to thecontrol system.

- Controller with software for independent control of all components, running alsoin case of interruption of communication between units or central display.

- Minimum Four temperature sensors located in the front and rear side monitoringthe air temperature in the upper and lower part of the space. Sensors could becalibrated from controller. Controller enables to change the logic between averageand maximal values, and arranges substitutability in case of failure.

- Two humidity sensors located at the bottom of front and rear part of the unit forprecise monitoring of the room conditions.

- Air-conditioning unit, with “D” in the type code, includes color touch screen inthe front door. 4.3” large display is equipped with special software for monitoringand control of up to 10 units. It enables communication through TCP/IP protocol,remote control via Ethernet and implemented webserver, and easy SW upgradingand data downloading via USB disk or SD card. Another function implementationis possible on special request.

Functions:

- The basic task is to cool down the air from the hot zone of datacenter anddistribute it to the cold zone in front of the IT equipment. The unit is designed tokeep the constant temperature in both zones thanks to the water valve adjustmentand variable fan speed.

- If the humidity in the hot zone is within the limits set by an administrator, then theunit’s internal logic tries to avoid any condensation of the air moisture, maximizethe cooling efficiency, and minimize influence on the humidity climate of theroom.

- Avoid condensation completely and maximize cooling efficiency.- If the measured air humidity is above the set point, then the unit is automatically

switched to the dehumidification mode, and actively supports the surfacecondensation to decrease the humidity in the room. The resulted condensate isdischarged to the drainage.

- The unit can be equipped by integrated steam humidifier which increases the roomhumidity to the set point.

- PAC should control humidity.- 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 smokedetector. The VESDA or the very early smoke detection system that provides the highestsensitivity appropriate for detecting a complete range of smoke particles produced inincipient stage and real fires involving natural or synthetic materials. It comprises of an airsampling 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 StrobeLight) in order to closely emulate the spectrum and intensity of sunlight itself. The systemhas a photoelectric receiver which is used to gather the scattered light having a broadbandspectrum. 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 involvedand combustion temperatures. Thus a broadband spectrum method of detection performswell 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 smokedetection and alarm. The air sampling is done in all the three voids of the Server room andthe Network room i.e., below the false floor, room void and above the false ceiling. Thisgives 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 andthrough the specially constructed detector head where it is exposed to a broadband spectrumof light. Light scattered by the particles pass through a series of optical components to anextremely sensitive solid-state light receiver. The receiver converts the light energy into anelectronic signal representing the level of smoke in the air sample. The receiver sends thissignal to a microprocessor where it is processed and presented on the bar graph display as oneof many lighted segments. This activates the alarm indication when appropriate.
