The objective of this project is to evaluate the energy performance of an absorption refrigeration fridge fed with renewable energy sources such as solar energy and synthesis gas, product of the transformation of corncob into a multizone gasifier, proposing alternatives for generation of energy that can be used in industrial, residential or non-interconnected areas (ZNI) in various regions of the country, improving their quality of life and competitiveness in the sector by having alternatives for the conservation of products. On the other hand, Córdoba, located in the northwest of Colombia, is privileged to take advantage of renewable resources, mainly the solar energy present throughout the year, it also has great potential for biomass since it is a corn-producing department, which can be used to generate energy through thermochemical transformations. Initially, temperatures were recorded at 6 points in the refrigerator using type K thermocouples, and the behavior of the thermal load was also evaluated by placing 1 liter of water internally to determine its stabilization temperature. An energy peak of 970.45W / m2 was obtained by characterizing the solar radiation. Temperatures were recorded for 24 hours, the results obtained were compared with the conventional energy sources that the refrigerator has as liquefied petroleum gas (LPG) and electrical energy (110V). Temperatures of 5.80 ° C in the thermal load were obtained with solar energy using a Photovoltaic solar Kit, 8.70 ° C using synthesis gas from a multi-zone gasifier, which were compared with Conventional LPG and 110V electric energy, the results of which were 9.60 ° C and 6.70 ° C respectively. The stabilization time in the thermal load was lower when electrical energy was implemented, which exceeds 800 min, followed by solar energy with 1,100 min, LPG exceeding 1,200 min and synthesis gas with 1,300 min. Finally, the energy performance (COP) was evaluated for each energy source (Electric, Solar, Synthesis Gas and LPG) obtaining (2.60; 2.38; 3.28; 3.67) respectively.
