ABSTRACT
This chapter describes the range of transportable, small and fixed buildings in use in rural and remote areas in Australia. The buildings have been designed with features to promote the natural transfer of heat from the equipment room to its surroundings and to limit the room-temperature rise to an acceptable level. The equipment buildings designed in Australia generally belong to two classes: thermally thin lightweight construction or heavy-weight construction with high thermal inertia. Modern line transmission equipment and broad-band radio repeaters have an upper operating limit of 50 °C and at 55 °C the equipment must remain operational without suffering damage or permanent degradation of performance. The thermally transparent shelter type has the property of maintaining a small temperature difference between the internal and external temperatures for high equipment heat loads without additional passive heat-removing devices. Heat-dissipating equipment inside the cabinets has been placed in such a way as to enhance the natural internal convection air currents.
