Abstract: A cooling system of a server with an AC power source and a DC power source includes an AC input subsystem, a DC input subsystem, and a driving control subsystem. The AC input subsystem receives an external AC power source and provides a first DC voltage and a second DC voltage. The DC input subsystem receives an external DC power source and provides a third DC voltage and a fourth DC voltage. When the external AC power source normally works, the driving control subsystem controls the first DC voltage and the second DC voltage to supply a high-voltage cooling apparatus and a low-voltage cooling apparatus, respectively. When the external DC power source normally works, the driving control subsystem controls the fourth DC voltage and the third DC voltage to supply the high-voltage cooling apparatus and the low-voltage cooling apparatus, respectively.

Abstract: An air conditioning system includes a control unit, a circulation system, an AC-to-DC conversion unit, and a fan module. The control unit detects an area temperature, controls the compressor unit being in operation or not in operation according to the area temperature and a setting temperature set by the control unit, and control a rotation speed of the condensing fan according to a temperature difference between the area temperature and the setting temperature. When the area temperature is greater than the setting temperature, the control unit controls the compressor unit being in operation and control the condensing fan being in full-speed operation.
