Data centers are the backbone of the telecommunications
industry.ITequipment consumes considerable amounts of
energy, which is released inthe form of heat. In order to
dissipate the generated heat, it is necessaryto use airconditioning systems whose task is to maintain appropriate
airconditions inside the server room.The study proposes and
analyses 4 variants for the modernization of thecooling system
in terms of energy consumption. The modernized object isa
server room with a total heat load of 1358 kW. In the facility
there areinstalled air-conditioning cabinets, dating from 2005,
based on directevaporation.In variants 1 and 3 it was decided
to replace the existing air conditioningcabinets with newer
models. In Option 3, the indoor air temperature wasfurther
increased.In variants 2 and 4, it was decided to replace the
existing solution with asystem based on chilled water and to use
chillers with a free coolingfunction. In variant 4, as in variant 3,
the air temperature in the serverroom was increased.The
analysis carried out showed the greatest reduction in
energyconsumption for variant 4 (51.51%). In case of the
remaining variants, theenergy demand decreased by 11,11%;
19,76% and 34,60% respectivelyfor variants 1, 2 and 3,
