Packaged Cogeneration Systems for Energy Productıon in the Residential Buildings – a Case Study in Konya
(Konya Technical University, 2019) Kaplan, Mehmet; Büker, Mahmut Sami
Cogeneration (CHP-Combined Heat and Power) is a modular system where heat and electricity are produced jointly. These units, building types with small capacity, utilise natural gas to generate electricity to be consumed in the buildings. They also generate waste heat during electricity production, which is exploited for heating and domestic hot water needs. CO and NOx emissions of these environmentally friendly systems are negligible as compared to conventional counterparts. In addition, there is no dust and sulphur emissions arouse through these systems. In this study, the performance evaluation of a micro cogeneration system for residential sector in Konya city has been conducted. The micro-cogeneration system, having 71 kWe of electrical and 115 kWt of thermal capacity, was implemented in a housing project with 137 flats. The corresponding findings from the system operation show that 18.480 kWh of electricity was generated per month against 6.998 m³/month of natural gas consumption. Moreover, the electricity withdrawn from the network decreased 51% with the introduction of micro-cogeneration system. While the average hourly power production of the micro cogeneration unit was 48 kW in winter season, it was 30.54 kW per hour in summer season. According to the analysis results, it was observed that the total system efficiency of 87% was attained. Corresponding economic indicators reveal that an average economic return of $22.10 per flat was obtained. In addition, the sleep mode of cogeneration unit was observed to be 44% higher in summer season. Overall, the aim of this study is to shed light on the applicability of this system in residential sector in Turkey.
