Close Control Air ConditioningTemperature control

Close Control Air Conditioning (CCAC) was created in the 70’s in order to meet the needs of a very technological and specialized élite: keeping the thermal-hygrometric (temperature and relative humidity) and air purity conditions within strict limits in rooms where the first computers used to work.

It was clear that those devices emitted a great amount of heating, and that their working operations could be guaranteed only at appropriate indoor climate conditions.

11www.jetrun.ro



Closed Control Air Conditioning has the aim to provide the right electronic and other devices working which emit sensible heat by keeping and controlling, within strict limits, the treated air’s following parameters:

Close Control Air ConditioningDATA CENTER INDOOR LAY-OUT

PERIMETER INSTALLATIONConditioners are placed along walls in Data Center or in aisle/technical outdoor space. The latter solution allows control and maintenance operations without entering the electronic equipment area.

18www.jetrun.ro


IN-ROW / IN-RACK INSTALLATIONConditioners are installed between a rack and another with air supply in the cold aisle and air return from the hot aisle (in-row installation), or with air supply and return directly inside the rack (in-rack installation).


19www.jetrun.ro


HOT / COLD AISLEElectronic devices taking cold air from the front and discharging hot air from the back allow to create hot and cold aisles within the Data Center and make uniform (in the whole volume) room temperature not necessary.


20www.jetrun.ro


CONTAINMENTCold aisle closure with doors and covers between racks to keep the “produced” cold in the occupiedvolume. In some installations the hot aisle is closed and kept at negative pressure.

Turbocor chillers

SMARDT OIL FREE CHILLERBest in class energy efficiency

All Smardt chillers, are designed to optimize the performance of the oil-free centrifugal compressors from Danfoss Turbocor Inc. These compressors use oil-free magnetic bearings and variable-speed drives to deliver superior efficiencies than conventional oil-lubricated centrifugal, reciprocating, scroll and screw compressors.

Smardt-Chiller - Soft Start

Diagram: Smardt chiller, require only 2 amps for start-up, compared with 500-600 amps in conventional machines. (100TR/ 350kW Chiller)

Further savings for owners, who can reduce maximum power loads and reduce backup generator size.

30www.jetrun.ro


Smardt-Chiller - Oil-Free Performance

As this comparative ASHRAE (research Study 601) study showed, lubricated chiller's operating efficiency is routinely lost in the early years as a result of oil clogging of heat transfer surfaces. The average overcharge of oil in the system was 12.88%, this equated to an average energy loss of about 21%

Diagram: oil in the cooling system of installed chillers

Diagram: e.g. only 3.5% oil in the refrigerant charge reduces system efficiencies by 8%

Keep in mindBoth cooling systems are commonly used for cooling data centres. The choice of cooling system is dependent on several factors, but in general one can say that, for lower cooling outputs (data centres with ICT devices of a total power output of c. 300 kW) DX systems are used and for larger outputs above 300 kW it is worth using CW systems. The exact point at which either DX or CW systems are applied cannot however be stated with such certainty. between chilled water use or direct expansion use is not so marked.

Heavy duty service 24h/365d/year

Load sharing(all units work at partial load)

Air cooled chillers and condensers in low noise version

Chillers with free-cooling sections for installations in cold/continental climate zones

Variable water flow to chillers. The combination of inverter-driven compressors and flooded evaporators allows to dispel the taboo of a constant water flow in the chiller resulting in pumping energy saving.
