Studies on a Low Concentration Photovoltaic/Thermal System with Constant Volume Refrigeration

Abstract:

To conserve operation energy consumption and improve outflow availability, a novel low concentration photovoltaic/thermal system with constant volume refrigeration was proposed in this paper. The outdoor experiment, carried out in Nanjing, suggested that the thermal efficiency could approach to 39.4%, while the electrical efficiency could reach 14.1% with 40 outflow. Applying the implicit finite-volume method, a model of this system was also derived. Based on the measured environment data, the performance of this system was simulated and validated by the experiment data.
