摘要：The paper deals with a model-based analysis of innovative cooling systems, to be deployed in
telecommunication (TLC) plants in consideration of their size, geographical location and
typology (e.g. central Offices or data-centers). Environmentally friendly systems, such as
geothermal heat pumps and trigeneration plants, were considered. The trade-off between the
investment and operating costs was first analyzed, followed by a comparative evaluation of
economic savings achievable via each candidate solution with respect to reference benchmarks,
here represented by traditional air-water heat pump and conventional interaction with electrical
grid. In this way, a preliminary macroscopic assessment of the best solutions was accomplished,
according to the different scenarios (i.e. small or big TLC plant) under investigation. A more
detailed analysis, concerning the comparison between traditional and geothermal systems, was
specifically carried out to evaluate savings as a function of the external temperature and,
consequently, of geographical location.
