Applicability of Tri-generation Energy Production for Air-conditioning Systems in Czech Republic

Original language description

The Czech Republic legislation encourages utilizing of all kinds of poly-generation systems. Local distributors of electricity must buy at a special price all electricity produced by poly-generation systems. Year operation hours of poly-generation systems are limited only by actual heat requirements. The cogeneration unit used in the studied building runs 6350 hour per year without utilizing of an absorption cycle. This period is extended to 7250 hour per year in a case of utilizing of the tri-generation technology driven by heat from a cogeneration unit. This extension enables to operate the cogeneration unit effectively even during summer period, commonly without heat requirements. Poly-generation of energy is connected with saving of a primary energy sources. The cogeneration technology decreases consumption of the primary energy by 29 %. The tri-generation technology decreases consumption of the primary energy by 20 %. We calculated the payback period as a basic economical criter
