Summary

The analysis of a typical container for telecommunication equipment was done to determine the potential for passive cooling. It was specified that throughout the year the temperature inside the container should not exceed 45°C. TRNSYS software package was used to analyze the temperature profile and annual cooling energy based on internal heat loads and outside conditions. Outside conditions were simulated using data for a typical meteorological year in Zagreb and Split, published by the Croatian Meteorological and hydrological service. The results showed considerable potential for natural ventilation and heat rejection through the container envelope. Therefore, it has been proposed to use an envelope made solely of aluminum panels, without the insulation. Furthermore, the proposed construction has ventilation grilles and a chimney to enable passive cooling, as well as an axial fan for periods during which natural ventilation is not sufficient. The results suggest that the proposed solution could completely eliminate the need for a conventional system, despite relatively high internal loads from the telecommunication equipment. The estimated annual electricity consumption for cooling is up to 82 times lower than for a conventional container with a split-system (assumed COP = 3).
