Abstract: (88 Views) |
| In this research، a combined heating and electricity cooling system is proposed and a complete thermodynamic analysis is presented. This system consists of a gas turbine، a thermal cooling system، a cogeneration system and a hot water heat exchanger. The excess heat in the gas turbine is initially produced by the cogeneration system and converted into power through an ammonia steam turbine. Will be then، the output steam of the ammonia steam turbine is used in a single-effect water absorption refrigeration system to produce cooling energy. Effective use of produced surplus energy can reduce natural gas consumption compared to independent power systems، cooling and heating. The energy and exergy efficiency of the studied system is 20 and 21 %، respevtively، wich is a resonable value. The results of economic analysis show that the produced system has a high economic efficiency with a total cost of 93.56 dollars per second and a total investment and maintenace cost of 1732 dollars per second. This work will provide a new method to increase efficiency and effectiveness of the thermodynamic performance of cogeneration systems. |
