Abstract

Herein, a solar-powered vapor compression refrigeration system for vaccine storage was proposed. The system comprises a 535-W photovoltaic module, a 60-A charge controller, a 200-Ah lead–acid battery, a 3,000-W inverter, and a 75-W commercial vapor compression refrigerator. The refrigerator is directly connected to the inverter. The experiments were conducted at Silpakorn University (13.82°N, 100.04°E), Nakhon Pathom, Thailand. It was found that the load temperature can be reduced from the ambient temperature of 26°C–28°C to 0°C within 18 h for small load (3.75-15.00L). Technically, the system performs well and can be used for vaccine storage. Also, the ARX modeling approach can be used to predict the load temperature with acceptable accuracy. From the economic analysis, the payback period of the system is 11.34 years.
