Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, specifically relates to a solar refrigerator, in particular to a composite system composed of a solar adsorption refrigeration system and a solar photovoltaic DC refrigeration system. Background technique [0002] Solar energy is a clean and renewable energy that is widely used in modern society. Solar refrigerators play an important role in the storage of vaccines, medicines, and food in remote areas. Among them, solar photovoltaic refrigerators and solar adsorption refrigerators are the most practical, but there are still some problems in the application and promotion of these two solar refrigerators. [0003] Solar photovoltaic refrigeration is driven by solar photovoltaic power generation to drive refrigerator compressors to cool. Most of them use crystalline silicon photovoltaic cells with high photoelectric conversion efficiency at room temperature. Using the electric ener...
