Davlumbazlarda Kullanılan Komponent Özelliklerinin Enerji Tüketimi ve Çalışma Performansı Üzerine Etkisinin Deneyselİstatiksel Olarak İncelenmesi

Bu çalışmada mutfak davlumbazlarında kullanılan, motor ve filtrelerin ürün performans ve enerji tüketimiüzerine etkileri deneysel ve istatiksel olarak incelenmiştir. Bu amaç için mutfaklarda kullanılan iki farklı boyutasahip piramit tipi, davlumbaz seçilmiştir. Deneylerin gerçekleştirilmesi için iki farklı boyutta (60–90 cm) gövde,iki farklı özellikte motor (450-650 m3/h) ve iki tip filtre (3-5 katman) konfigürasyonuna sahip davlumbazlarınüretimi yapılmıştır. Çalışmanın deneysel tasarımı Taguchi L8 dizilimi kullanılarak oluşturulmuş ve deneylergerçekleştirilmiştir. Deney sonuçları incelendiğinde, 60cm boyuta sahip davlumbazların yıllık enerji tüketimi(AEC) en düşük 43,6 kWh iken en yüksek 62,7 kWh olduğu ve 90cm boyuta sahip davlumbazların ise en düşük48,7 kWh iken en yüksek 63,0 kWh olduğu görülmüştür. Filtrelerin yağ tutma verimliliği incelendiğinde endüşük yağ filtre verimliliği %68,4 olarak 90 cm boyuta sahip davlumbazda ve en yüksek %80,6 olarak 60 cmboyuta sahip davlumbazda oluşmuştur. Deneysel sonuçların istatiksel olarak incelenmesinde Sinyal/Gürültüoranları, Anova ve Regresyon analizleri kullanılmıştır. Sinyal/Gürültü oranları incelendiğinde en verimlinoktadaki debi (QBEP), yıllık enerji tüketimi (AEC), maksimum devirde hava akışı, gürültü performansı (LWA) veyağ filtresi verimliliği (GFE) için en ideal seviyeler sırası ile A2B2C2, A1B1C2, A2B2C2, A2B2C1 ve A1B2C1 olarakbelirlenmiştir. Anova sonuçları incelendiğinde QBEP, AEC, maksimum devirde hava akışı ve LWA için en etkiliparametrenin sırası ile %96,62, %93.02, %98,87, %41,45 oranla motor , yağ filtresi verimliliği için en etkiliparametrenin ise %62,72 oranla filtre katmanı olduğu tespit edilmiştir.

Experimental-Statistical Analysis of the Effect of Component Properties Used in Hoods on Energy Consumption and Operating Performance

In this study, the effects of motors and filters used in kitchen hoods on product performance and energy consumption were investigated experimentally and statistically. For this purpose, two differentsizes of pyramid hoods used in kitchens were chosen. In order to carry out the experiments, hoods with two different sizes (60–90 cm) body, two different engine (450-650 m3/h) and two types of filter (3-5 layers) configurations were produced. The experimental design of the study was created using the Taguchi L8 sequence and experiments were carried out. When the experiment results are examined, the annual energy consumption (AEC) of the 60 cm size hoods were found to be the lowest 43,6 kWh, the highest 62,7 kWh and for the 90 cm size hoods were found to be the lowest 48.7 kWh and the highest 63.0 kWh. When the grease retain efficiency of the filters was analyzed, it was observed that the lowest greas filter efficiency was in the 90 cm size hood with 68.4% and the highest greas filter efficiency was in the 60 cm size hood with 80.6%. Signal / Noise ratios, Anova and Regression analyzes were used for statistical analysis of experimental results. When the signal / noise ratios are analyzed, the most ideal levels for flow rate (QBEP), annual energy consumption (AEC), maximum flow air flow, sound performance (LWA) and grease filter efficiency (GFE) are determined as A2B2C2, A1B1C2, A2B2C2, A2B2C1, A1B2C1 respectively. When the Anova results are examined, the most effective parameters for QBEP, AEC, maximum speed air flow and LWA are determined as engines with 96.62%, 93.02%, 98.87%, 41.45%, respectively, the most effective parameter for grease filter efficiency was determined as the filter layer with a rate of 62.72%.
