چکیده
In the present paper, the energetic and exegetic analysis of using parabolic trough solar collectors (PTSC) subsystem with an organic Rankine cycle (ORC) at the engineering faculty of Urmia University that located in Nazlou regain as a case study is carried out. The task of this cycle is to provide the heating load and electrical power of the building. Firstly the energy demand of the building is calculated. Then, by considering the geographic location and weather conditions information of Nazlou, a cycle that fits with it, in three solar radiation modes is designed. These modes are the solar mode, the solar and storage mode, and the storage mode. According to results, total heating load and electrical power rate of the building are 1253.2 kW and 1500 kW, respectively. This energy demand can be provided by 250 and 500 number of PTSC in the solar mode and the solar and storage mode, respectively. PTSC outlet temperature and its efficiency during the year are between 470-660 K and 53-56%, respectively. Heating cogeneration and electrical power energy efficiencies in the first and third mode are around 95% and 15% and in the second mode are around 45% and 7.5%, respectively. Heating cogeneration, electrical power and ORC exergy efficiencies are around 18.5%, 9.5%, and 9% in the first and third mode, respectively. For second mode these values are around 9%, 4.5%, and 4%, respectively. Also, the major exergy destruction rate is occurred in the PTSC and ORC evaporator.
