Zusammenfassung:PROBLEM TO BE SOLVED: To provide a space-saving cooling system for a data center that can quickly switch from a compression cycle to a natural circulation cycle.SOLUTION: In the cooling system for a data center that includes a compressor (5), a condenser (3), an expansion valve (6), an evaporator (1) for absorbing heat from an electronic apparatus (51), bypass piping (25) bypassing the compressor and passage changeover means (21, 22, 23) and that can operate the passage changeover means to operatively switch between a compression cycle and a natural circulation cycle, the condenser comprises a plurality of divided condensers (3a, 3b), and at least part (3b) of the plurality of divided condensers includes a straight heat exchanger tube extending vertically. With a predetermined amount of liquefied refrigerant stored in the part divided condenser (3b), the other divided heat exchanger (3a) can be used to provide a compression cycle operation.
