Klima Sistemlerinde Kurulum Hataları Etkilerine İlişkin Genel Değerlendirme ve Enerji Analizi

Öz

Bu çalışmada, ev tipi klima (AC) sistemlerinin yoğuşturucu bölümündeki montaj hataları araştırılmıştır. Konut binalarındaki AC sistemlerinin elektrik tüketimi sürekli artmakta ve önemli endişelere yol açmaktadır. Bu sistemlerin elektrik tüketimini ve emisyon değerlerini azaltmak için çok sayıda çalışma yürütülmüştür. Ancak, bu sistemlerin doğru bir şekilde kullanılıp kullanılmadığı ve kurulup kurulmadığı hala şüphelidir. Bu çalışmada, yoğuşturucu bölümündeki montaj hatalarının etkileri deneysel olarak araştırılmıştır. Bu hataların sistem performansı üzerindeki etkisini değerlendirmek için bir enerji analizi yapılmıştır. Bulgular, montaj hatalarının temel değerlere kıyasla %40 ila %60 arasında değişen bir elektrik tüketimi artışına neden olduğunu ortaya koymuştur. Ayrıca, bu hatalar nedeniyle AC sisteminin performans katsayısı (COP) %48,75 oranında düşmüştür. Ayrıca, Japonya, ABD ve Çin'deki AC sistemlerinin kullanımı göz önünde bulundurularak, yoğuşturucudaki montaj hatalarının neden olduğu gereksiz enerji tüketimini hesaplamak için gemel bir değerlendirme yapılmıştır. Sonuçlar, kurulum hatalarından kaynaklanan yıllık gereksiz enerji tüketiminin her ülke için 0,05 TWh ile 1,26 TWh arasında değiştiğini göstermiştir.

General Evaluation and Energy Analysis on the Effects of Installation Faults in Air Conditioning Systems

Öz

In this study, the installation faults in the condenser section of household air conditioning (AC) systems were investigated. The electricity consumption of AC systems in residential buildings has been steadily increasing, raising significant concerns. Numerous studies have been conducted to reduce the electricity consumption and emission values of these systems. However, it remains questionable whether these systems are being used and installed correctly. This study experimentally investigated the effects of installation faults in the condenser section. An energy analysis was carried out to evaluate the impact of these faults on system performance. The findings revealed that installation faults caused an increase in electricity consumption ranging from 40% to 60% compared to the baseline values. Additionally, the coefficient of performance (COP) of the AC system decreased by 48.75% due to these faults. A general evaluation was also performed to calculate the unnecessary energy consumption caused by installation faults in the condenser, considering the use of AC systems in Japan, the USA, and China. The results indicated that the annual unnecessary energy consumption due to installation faults ranged from 0.05 TWh to 1.26 TWh for each country.
