Abstract: (121 Views) |
The present study conducts an energy evaluation of a new solar tri-generation design for cooling, heating, and power generation of a hospital complex. The proposed system contains linear Fresnel concentrating collectors and photovoltaic thermal absorbers, which use solar energy to produce electrical and thermal energy for sale and partially provide the energy for cooling and heating cycles. The proposed cooling system in this structure is a single effect LiBr-H2O absorption chiller. For the cases of cooling and heating systems, energy demand is more than solar energy production; gas fire backup heaters are intended. The annual system performance under the air conditioning load of the hospital complex is presented. The results show that the solar cycle provides 30% of the system's annual energy supply. In addition, the proposed structure also generates 77.7 MWh of electrical energy. The understudy system provides all its required energy from solar energy on the hottest day of the study from 9 to 15. The proposed collector has a better performance than photovoltaic thermal and concentrating Thermal collectors.
