COOLING A DATA CENTER BY RECIRCULATING AIR USING AN AIR-TO-AIR HEAT EXCHANGER WHEEL

摘要

Disclosed are an apparatus, method, and the use of an air to hear heat exchanger of the rotary type in the form of a heat wheel (13). The heat wheel is used for cooling recirculation air of an air humidity- and temperature-conditioned space (8) of a data centre. The data centre contains ICT and/or telecom equipment. The method involves supplying air heated by the equipment as a first air stream (11) to the wheel, and cooling the stream using a separate second air stream (12).
