| Summary: | Introduction— The use of renewable sources for energy generation has grown in importance due to the adverse effects that fossil fuels generate on the environment. From the available sources, generation of energy through biomass has great advantages because of its high energy potential and low cost. Objective— To evaluate the performance of a heat absorption refrigeration system using photovoltaic solar energy conversion and biogas as renewable energy sources. Methodology— The energy characterization of the implemented sources was carried out collecting data on solar radiation and biogas calorific value to calculate the Coefficient of Performance (COP). All the experimental tests were made by placing 1 liter of water inside of the system. Results— It was found that the operation of the equipment takes approximately 8 hours, the biogas chemical composition was 58% methane and 42% carbon dioxide, and a calorific value of 23.05 MJ/kg was attained. The Coefficient of Performance obtained were 0.58; 0.08; 0.27 and 0.07 for electrical energy, LPG, solar energy and biogas respectively. Conclusions— There is an important energy potential in the usage of solar energy and biogas for cold generation processes and it was proved that it is possible to implement renewable energies in absorption cooling systems |
