 AbstractIn this work the performance of a cold production plant using biomass residuals from an agrarian exploitation as the primary energy source is analyzed. These residuals are generated in the pruning and renovation of fruit trees and are used in a boiler to convey heat to an absorption refrigeration engine. At first the study carries out the characterization and quantification of the energy produced by the residuals. Furthermore, it ponders on the viability analysis of converting that energy in cold by means of an absorption machine. The estimated thermal power sourced from the biomass generated in the exploitation (approx. 4216 ton) is of approximately 56.92 × 106 MJ/year. This energy was shown to be greater than that required to keep the fruits at a suitable low temperature, thus obviating the use of conventional refrigeration and avoiding their associated high energy consumption.
