  Abstract Text

  Cogeneration systems, if properly designed and operated, save primary energy, because they have higher efficiencies than the efficiencies of separate production of electricity and heat and are usually much closer to the consumers, thus reducing the losses in transportation and distribution networks. One of the most important parameter for the evaluation of cogeneration plants is primary energy savings, defined in European Directive on the Promotion of Cogeneration. Reduction of primary energy consumption often results with lower degree of air pollution and economic benefits. In this paper, primary energy savings that might be achieved with the implementation of high efficiency small scale cogeneration plant are discussed. The plant is based on the natural gas-fired reciprocating engine and absorption chiller that uses heat produced by the engine to obtain the cooling energy. The estimation is based on optimized operation winter and summer regimes of the discussed cogeneration plant. The objective function is primary energy savings, i.e. primary energy consumption. « hide
