IIR documentSummary
The paper analyses the behaviour of the UPS (Uninterruptible Power System) cooling system under summer circumstances. The problem is that for the proper functioning of a UPS unit, the inside temperature must be less than 30 °C. In other case the batteries tend to lose energy and electronic systems start to overheat. What is taken into consideration is the influence of solar radiation on a UPS container (it depends on the placement and time during the day). Next, there is a description of incoming and outgoing heat streams. Furthermore, the paper calculates the heat balance and discusses the installed cooling system. The question is: is the cooling system capable of keeping the temperature in the container under 30 °C in case of hot summer or not?
