Summary

Trigeneration means simultaneous generation of electricity, heat and cooling power. A conversion of cogeneration heat to cooling power is achieved predominantly with sorption technologies – adsorption and absorption chillers. Thermodynamic optimization of trigeneration requires possibly low temperature of the heat converted to cooling power. The temperature should not exceed 65 °C, to enable the conversion of district heat to ice water supplying air conditioning chillers. The paper presents the exploitation experience of Zielona Góra gas cogeneration plant converted into trigeneration installation. The conversion allows the change of the plant operation principle. It is not oriented on flexible heat generation but it serves as the balancing unit in Polish electro energetical system. The comparative analysis of the losses accompanying heating and cooling power distribution is presented and discussed on the basis of second law of thermodynamics. An ice water distribution dedicated network has been designed. Adsorption and absorption technologies are discussed and compared with respect to their applicability in district heating and cooling. Trigeneration system configuration allowing the reduction of primary energy consumption is proposed. A role of trigeneration plants in Polish power generation mix allowing increase of non-stable renewables sources of energy  in power generation mix is discussed.
