According to the characteristic of solar photovoltaic, this paper designed an electric supply mode, combined with the solar photovoltaic system, the storage battery and the public power supply, to drive a portable refrigerator which could use outdoor. The refrigerator is installed two individual refrigeration systems with two special arranged evaporators and wind route for storing beverages under the sunlight. Besides, the refrigerator electricity supply has three ways including utilizing solar energy with sun shining, taking advantage of the storage battery in night time and making use of the public power while the sunlight is unavailable. Various tests are carried out to examine the performance of the system. The voltages and currents which are generated by the solar cell and monitored on refrigerator have been studied. In addition, an analysis in power consumption of the system is realized. The results indicated that the refrigerator could run normally and indeed satisfy the request in beverage cooling and storage.
