Thermal management and performance enhancement of data centers architectures using aligned/staggered in-row cooling arrangements

Effect of in‐row cooling units numbers/locations on thermal and energy management of data centers servers

“…Air temperatures distributions along the heights of the racks intake and discharge were recorded after maintaining steady state conditions. Details of the experimental setup and procedure can be found in Abbas et al 33 A numerical simulation model of the porotype data center room was also formulated through Ansys-IcePak software for validation. The physical model of the simulation has a typical dimension of the prototype room.…”

“…The configuration of having each rack sandwiched between two racks (Configuration C), is not recommended as it needs the largest white area with the smallest occupancy factor of the racks units and at the same time the total costs of the CRACs units is higher than that of configuration B. Accordingly, it can be concluded that configuration B with two cracks units sandwiched between each two CRACs is the optimal configuration as it has the lowest total cost of the CRACs T A B L E 4 CRACs costs of the configurations A, B, and C [32][33][34]…”

“…31 In another CFD comparison study, Abbas et al 32 reported that raided floor cooling architectures is suitable for low power density and in-row cooling is suitable for high power density. Later, Abbas et al 33 reported that the effect of the staggered and aligned arrangements of CRACs unit of the different rows of in-row cooling system is small. The present literature review shows that in-row cooling architectures of data centers has better performance comparing to raised floor cooling architectures.…”

Experimental and numerical investigation on thermal performance of data center via fan-wall free cooling technology

“…Their results showed that the servers could have the best thermal performance when they were evenly distributed across the racks. Abbas et al [30] and Nada et al [31] analyzed the influence of the air conditioning alignment and interleaving on the cooling efficiency of the row-based air conditioning DC. They concluded that the cooling effect of the air conditioning units' staggered arrangement in racks could be better than that of aligned arrangement.…”
