UPS is an electrical apparatus that provides emergency power to a load when the input power source, typically mains power, fails. When installing UPS in outdoors (a road near or mountain, etc..), it is also possible many problems according to the outdoor environment. And it is possible generate condensation by a temperature difference The purpose of this study was to predict the inner temperature of UPS and to prevent dew condensation in UPS by simulating the heat flow using ANSYS. So in this study, The inner heat flow simulations for UPS were conducted by the Computation Fluid Dynamics Analysis, ANSYS, during the active state of UPS. Compared with Air temperature, Relative humidity, Inner temperature of UPS to be found that condensation is occurring. It’s can be improved by ventilation or insulation effectively inside UPS according to this simulation result.
