COOLING APPARATUS AND METHOD

摘要

Cooling apparatus providing two independent heat exchangers (18, 20) serially arranged with respect to a heat flow (42), each heat exchanger being connected to a respective independent chiller (32, 34). The apparatus incorporates an element of redundancy in order to effect an increase in operational efficiency, by being switchable between a first operation mode in which both chillers operate in a free cooling mode and a second operation mode in which a first chiller operates in a free cooling mode and a second chiller operates in a forced cooling mode.
