Abstract: This paper presents a solar field configuration to supply thermal energy to the heating and air conditioning system of a hotel located in Almería (Southern Spain). The solar collector technology selected for the solar field is parabolic trough collector (PTC) technology, in particular a small sized PTC prototype especially designed for industrial process heat and air-conditioning systems. Each PTC collector is 8m long and its aperture length is 1m. The heat transfer fluid in the solar field is pressurized hot water. Considering the space available for the solar collector field just close to the hotel and its thermal energy demand profile, the solar field configuration proposed consists of 8 parallel rows, north-south oriented, composed of 32 PTCs connected in series. With this solar field configuration, 25% of the cooling demand is covered the hottest day of the summer and 76% of the heating demand is covered the coldest day of the winter. [Copyright &y& Elsevier]
