Experimental study of a micro-refrigeration system driven by photovoltaic power generation

摘要： A micro-refrigeration experimental system driven by photovoltaic power generation was established, and a study of the cooling capacity, load power, and system efficiency changes over time under sunny and cloudy weather conditions was carried out. The results show that the appendant battery makes the system run more stably, and the weather has no obvious effect on the operation of the indoor refrigeration system. The system exergy analysis indicates that the exergy loss of the compression process is the largest, accounting for more than 80% of the total in the refrigeration system; The exergy efficiency of the refrigeration system can reach about 28% under both weather conditions.
