Feasibility of Utilizing CHP Systems in Reduction of CO2 Generation in Residential Units

In this paper the application of CHP systems in reduction of energy consumption as well as CO2generation has been evaluated. A residential tower and an apartment have been considered as case studies. CHP system has been selected based on two scenarios (heat and power demand base) for both cases. The results show that the energy consumption as well as CO2 generation decrease when CHP has been designed based on power demand, while the fixed cost increases. In this case, CHP systems with capacity of 10 and 700 kilowatt are adequate for an apartment and residential tower respectively. Meanwhile the results show that in the second scenario (heat demand) the fixed cost decreases while energy consumption and CO2 will increase.
