Abstract
This paper presents an experimental study on the solar hybrid vapor compression refrigeration (SHVCR) system in indoor and outdoor conditions. This system was tested in indoor condition and compared with the outdoor condition. The energy consumption and temperature variation inside the refrigerator were recorded in both conditions. The effect of meteorological parameters on the performance of SHVCR system was analyzed. The results showed that the performance of this system was depended on indoor and outdoor conditions. The refrigerator cooling rate in indoor condition was faster as compared to outdoor condition. The per day energy consumption of this system in the outdoor condition was 112 Wh to maintain average lower temperature −12 °C inside the refrigerator chamber. The per day energy consumption of this system in the outdoor condition was recorded 78 Wh. The energy consumption of this system was 30% lower in indoor condition as compared to outdoor condition. The proposed SHVCR system was able to store lifesaving vaccines and perishable foodstuffs.
