Experimental Investigation of a Solar Photovoltaic DC Refrigerator with Cold Storage

This paper carried out comparative experimental investigation to test the operation performances of a solar photovoltaic(SPV) direct current(DC) refrigerator using a phase change material(PCM)、a photovoltaic DC refrigerator without PCM and a conventional household one. The solar photovoltaic DC refrigerator with PCM has many advantages on start-stop frequency of the compressor、operation ratio and heat insulation time during the motor stopped. Furthermore, the system is powered by solar energy completely without consuming any grid electricity for running, and is " the green household electric appliance” on real significance, that especially suitable for remote mountains and nomadic areas of fresh food and medical supplies of vaccine, etc.
