DOI: 10.15199/9.2021.2.3 Keywords: poly-generation, tri-generation, absorption chiller, primary energy consumption rate, direct and indirect cooling system Abstract The article describes different methods of producing energy carriers for building objects. Decentralized (dispersed) sources and centralized systems, in which the city's district heating systems have been used to produce chilled water for the air conditioning of facilities that are underloaded in summer, are discussed. Necessary modifications to the operating conditions of district heating systems are described, as well as the limit, minimum cooling capacity requirements to ensure energy and environmental efficiency of system operation. An outline of the theoretical and implementation work carried out in this respect in the country has been also presented, and several examples of solutions for tri-generation systems described.
