Experimental Study on a Solar Photovoltaic DC Refrigerator

摘要

The system of a 24V solar photovoltaic DC refrigerator was studied and analyzed in the paper. Solar energy is the only energy source used to power the refrigerator. The USB data acquisition instrument was used to collect the data of voltage, current and freezer temperature of the system during the operation. Experimental results demonstrate that the solar photovoltaic DC refrigerator can run normally; the running rate of the refrigerator is about 48.8% when it runs steadily with no-load and the average consumption of power is about 28.8W.
