Description	Abstract: The goal of the presented work is to enable the increase of energy load in one data rack up to 15kW. The work aims to find and subsequently optimize such passive elements for directing the air flow inside the data rack, which lead to the mass flow rate increase in the data rack while keeping the pressure loss. Target value of the mass flow rate in the data rack was 1 m3s-1 of air assuming a fifteen-degree temperature drop on IT devices fitted in the data rack. The work resulted in two optimized deflectors that serve for directing the air flow through the floor to the front of the IT device. Further increase of the mass flow rate in the data rack was solved with the help of additional side zones. All passive elements were first verified with the help of numerical simulations and subsequently also by experiments. The final optimized variant indicates, at the same pressure drop, an increase of the mass flow rate by 79%; the resultant mass flow rate of 0.97 m3s-1 enables to fit the data rack with device with a total capacity of 15 kW.
