<p><P>PROBLEM TO BE SOLVED: To provide a cooling device for an electronic apparatus, capable of cooling the electronic apparatus, even when a power supply suspension state occurs. <P>SOLUTION: An evaporator 21 is disposed on a server rack 10 to the evaporator 21; an electrical heating source unit 30, having a compressor 32 driven by commercial power, is connected via a first refrigerant circuit 18; and a gas engine heat source unit 120, having a compressor 121 driven by a gas engine 127, is connected via a second refrigerant circuit 19. In normal operation, a centralized controller 200 supplies a refrigerant from the electrical heat source unit 30 to the evaporator 21 by switching to the first refrigerant circuit 18, while in the power supply suspension state, the centralized controller supplies the refrigerant from the gas engine heat source unit 120 to the evaporator 21, by switching from the first refrigerant circuit 18 to the second refrigerant circuit 19. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
