This contribution presents the analysis of possible utilizing of a tri-generation system for effective electricity, heat and cool production. A tri-generation offers more effective utilizing of primary energy sources in comparison with separate production of different kinds of energy. Natural gas is considered as the most common primary energy source utilized in tri-generation units. This analysis respects the legislation and technical directives valid in the Czech Republic in year 2006. The analysis synthesizes technical requirements for production of heat during a heating period and production of cool during a cooling period. The studied tri-generation system consists from a cogeneration unit, based on a stroke engine technology, connected with a convenient absorption machine for production of cool water. The mixture of water and LiBr is considered as appropriate working-pair medium operating in the absorption cycle. This paper focuses on environmental benefit and economical assessment of a tri-generation technology in residences and mid-size buildings.
