A thermodynamic model was developed in computational platform EES (Engineering Equation Solver) and it's based on ideal processes, information supplied by the engine manufacturer and the absorption chiller, as well as experimental results and literature. This work also aims to expose constructive characteristics, experimental methodology adopted, problems identified, interventions and the solutions adopted in the resolution of problems occurring. / O presente trabalho apresenta uma análise teórico-experimental de uma planta de cogeração, composta por um chiller de absorção que utiliza a tecnologia NH3/H2O, um recuperador de calor e um grupo gerador a gás natural. A modelagem termodinâmica foi desenvolvida na plataforma computacional EES (Engineering Equation Solver) e está embasada em processos ideais, dados fornecidos pelo fabricante do motor e do chiller de absorção, bem como em resultados experimentais e da literatura. Este trabalho visa também expor características construtivas, metodologia experimental adotada, problemas detectados, intervenções realizadas e as soluções adotadas na resolução dos problemas ocorridos.
