The performance analysis of a LCPV/T assisted absorption refrigeration system

This paper presents a investigation on the performance analysis of a novel low-concentrating photovoltaic/thermal (LCPV/T) assisted absorption refrigeration system. In this hybrid system, the lithium bromide absorption chiller is adopted to make use of the hot water from the LCPV/T modules for energy saving and higher system efficiency. A detailed mathematical model was proposed for analyzing quantitatively the performance of the novel LCPV/T assisted absorption refrigeration system. Specific experiments were conducted to analyze the influence of primary parameters on the refrigeration performance of the system, including inlet hot water temperature, cooling water flow and refrigerant water flow. The results show that the Coefficient of performance of the refrigeration system (COPx) and the refrigeration capacity of the hybrid system was correlated with the inlet temperature, cooling water flow, and refrigerant water flow. It is concluded that the average refrigerating capacity of the system is 7.20 kW, the average COPx is 0.52 and the average outlet cooling water temperature of the LiBr absorption chiller is 15 degrees C.
