Özet
Kojenerasyon, bileşik ısı-güç üretim sistemleri (CHP-Combined Heat and Power) ısı ve elektriğin birlikte üretildiği modüler yapılı sistemlerdir. Konutlarda uygulanan, gazla çalışan ve genellikle küçük kapasiteli bu üniteler kurulduğu binalarda tüketilmesi amacıyla elektrik üretirler. Elektrik üretiminde açığa çıkan atık ısı, neredeyse hiç kayba uğramadan, ısıtma için kullanılarak enerji verimliliği sağlanır. Oldukça çevre dostu olan bu sistemlerin CO ve NO? salınımları diğer fosil yakıtlı sistemlere göre ihmal edilebilir seviyelerdedir, toz ve kükürt salınımları da yoktur. Bu çalışmada, Türkiye’de ilk defa, Konya’da inşa edilen 137 dairelik konut projesinde uygulanan 71 kWe ve 115 kWt kapasiteye sahip mikro kojenerasyon sistemine ait performans değerlendirilmesi yapılmıştır. Aylık tüketilen ortalama 6.998 m³/ay doğalgaza karşılık yine ortalama 18.480 kWh/ay elektrik enerjisi elde edilmiştir. Mikro kojenerasyonun devreye girmesi ile şebekeden çekilen elektrik enerjisinde %51 oranında azalma gözlemlenmiştir. Kış sezonunda mikro kojenerasyon ünitesinin saatlik güç üretimi ortalama 48 kW iken bu oran yaz sezonunda saatlik ortalama 30,54 kW olarak tespit edilmiştir. Analiz sonuçlarına göre, toplam verimlilik oranının %87 civarında olduğu saptanmıştır. Ekonomik göstergelere göre, daire başı aylık ortalama $22,10 civarında bir ekonomik getirisinin olduğu hesaplanmıştır. Yaz döneminde mikro kojenerasyon ünitesi uyku modunun kış dönemine oranla ortalama %44 daha fazla olduğu gözlemlenmiştir. Bu çalışma da ayrıca mikro kojenerasyonun konutlara uygulanabilirliği konusu analiz edilmiştir.
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.
