Experimental Investigation of Direct Solar Photovoltaics that Drives Absorption Refrigeration System

Renewable energy used for refrigeration applications has become essential very recently due to the fossil fuel crisis and global warming problem. Moreover, using photovoltaic PV generate electricity than inverters storage represents a high-cost process. This study aims investigate opportunity of output directly operate system. The absorption system uses heat as an source generator that drives doesn't have compressor but generator. As result, novel aspect this is use electricity's DC power heater provides needed without inverter AC electricity. difference here needs consistent steady electric supply. However, heating not restricted if voltage fluctuates bit. A 580 W was refrigerator with capacity 70 liters. During several tests, freezer fridge reached -26 C cabin temperature around 10 C. finding similar performance on conventional heater.
