Cooling systems
With the emergence and further increasing development of IT equipment, especially the new generation of servers, there was a problem of higher heat dissipation. Therefore, it is necessary to apply the appropriate solution in terms of cooling the server room, 356 days a year, 24 hours a day. ENEL PS as a distributor offers effective solutions based on the needs of investors and its desire in the form of APC solutions. APC offers solutions InRow and inroom that have a large flexibility (for large heat dissipation systems, changeable dissipation and dimensionally not occupying the large space in the data center).
InRow system was invented by APC and many international companies is developing this cooling concept. System with InRow units consists in setting the appropriate units between Rack cabinet and works on the principle that takes the warm air close to the rack cabinet, on the location of its source (hot zone), so injects cold air on the very rack enclosure (cold zone). On the basis of the cooling medium used InRow systems can be direct-expansion (the use of ecological Freon R-407C or R-410A, a refrigerant and an adequate external condenser cooling freon) or chillers - external cooling engine )which uses water as a cooling fluid or a mixture of water/glycol in the relevant respect) or chiller with free cooling (chiller has an additional heat exchanger which allow usage at temperature below 10°C) for greater system efficiency and lower power consumption.
Modular cooling system inroom Data Centers offers cost - effective and new approach to cooling and cooling - sensitive IT equipment.
