In both tests, inlet temperature is constantly defined with T = 20°C. Due to geometry changes, the required air-mass flow could be reduced by approx. 7%. As air flow is conducted directly to the open mesh floor in the second variant, an optimal flow of the server room is achieved.

Thus, the required power consumption of the air conditioner can be reduced considerably, since, on the one hand, less air-mass flow has to be cooled and secondly pumping capacity is being reduced.
