Sanayide Enerji Verimliliğini Arttırıcı Enerji Yönetimi Uygulamaları: Fırın, Kazan HVAC ve Soğutma Sistemlerinde

Bu çalışmanın amacı, endüstrilerde enerji verimliliğini artırmaya yönelik enerji yönetimi uygulamalarını göstermek ve analiz etmektir. Çalışmada, endüstriyel kuruluşlarda gerçekleştirilebilecek enerji verimliliği artırıcı uygulamalarının örnekleri ele alınmış, bu uygulamalar için tasarruf miktarı hesaplanmıştır. Çalışmada ele alınan başlıca enerji verimliliği uygulamaları: kazanlarda ve fırınlarda ısı geri kazanımı, ısı yalıtımı ve HVAC sistemlerinde ısı geri kazanımıdır. Bu çalışmanın sonucunda enerji yönetimi ve enerji verimliliği uygulamaları ile fırınlarda reküperatör kullanıldığında %38,2 oranında ısı geri kazanımı, %15,79 oranında yakıt tasarrufu sağlanmıştır. Reküperatör kullanılmadığında kazan ısıl verimi %64,46 iken, reküperatör kullanıldığında kazan ısıl verimi %76,54 ‘e yükselmiştir. HVAC sistemlerinde reküperatör ile %47 verimle, ısı değiştiricisi %51 verimle ve ısı pompasında 1,09 COP ile ısı geri kazanımı sağlanmıştır. Soğutma uygulamalarında, yalıtımlı odada %30,4 enerji tasarrufu sağlanmıştır.

Energy Management Practices for Improving Energy Efficiency in Industries: Furnace, Steam Boiler, HVAC, and Cooling Systems

The aim of this study is to demonstrate and analyse energy management practices to increase energy efficiency in industries. In the study, examples of energy efficiency increasing applications that can be carried out in industrial organizations were discussed and the amount of savings for these applications was calculated. The main energy efficiency applications discussed in the study are the heat recovery in boilers and furnaces, thermal insulation, and heat recovery in HVAC systems. As a result of this study, with energy management and energy efficiency applications, 38.2% of heat recovery and 15.79% of fuel savings were achieved when recuperators were used in the furnace. While the boiler thermal efficiency was 64.46% when the recuperator was not used, the boiler thermal efficiency increased to 76.54% when the recuperator was used. In HVAC systems, heat recovery was achieved with 47% efficiency with the recuperator, heat exchanger with 51% efficiency and 1.09 COP in heat pump. In cooling applications, 30.4 % energy saving was achieved in the insulated room.
