Analysis of Demand and Energy Saving at Different Types of Hotels with Integration of Solar Systems and Geothermal Heat Pumps

摘要

Performance analyses for integration of solar thermal, PV and geothermal heat pumps to different hotelrntypologies have been carried out in order to evaluate the potential of self-consumption promoted byrnEuropean Directives. Hotels are located in different climatic zones of Spain and Italy. Using the softwarernTRNBuild®, the buildings have been created and run under TRNSYS Simulation Studio. Four typologies ofrnhotels (urban, rural, beach and mountain) and five categories of guests were created (family, couple, youth,rnorganized travel group and business), reflecting existing different patterns of energy consumption. ThreernSpanish provinces and one mountain site in Italy with different weather conditions have been selected torncalculate total thermal, electrical and domestic hot water (DHW) demand. Systems were sized to coverrnapproximately 70% of DHW demand, according to Spanish Normative. In addition, by using the selectedrntechnologies it is possible to supply all the electricity demand according to different patterns. In particular, itrnwill be shown that it is possible to supply 50% of total energy with PV panels - a value above the objectivesrnof the European Union for 2020.
