Raffreddamento evaporativo indiretto per il data center

lndirect evaporative cooling is an effective way to increase energy efficiency of Data Center air conditioning systems. In this work, an indirect evaporative cooling system based on a cross flow plate heat exchanger has been widely tested, in order to evaluate the effect of different system setup on performance. In particular, three different pos­itions of water nozzles have been analysed: installation respectively on the top, on the side and on the bottom of the heat exchanger. Tests have been performed in typical Data Center operating conditions: results put in evidence that best performance is achieved when water and air stream are supplied from the top of the system.
