Küresel ısınmayla birlikte klima kullanımı artmaktadır. Bu durumu birçok önemli kurum da dile getirmektedir. Ancak klima montajından dolayı ciddi sorunlar ortaya çıkmıştır. Özellikle klimaların kondenser ünitesi montaj hatalarının ekserji yıkımına olan etkileri bu çalışma kapsamında ele alınmıştır. Montaj hatalarından sonra klimaların kondenser ünitesinin hava girişi çeşitli nedenlerle engellenmektedir. Bu durumun ekserji yıkımına olan etkisi incelenmiştir. Kondenser montaj hatalarında elde edilen sonuçlara göre AC sistemin ekserji verim değerleri %38 ile %19 arasında hesaplanmıştır. Kondenser-ekserji analizinde ekserji yıkımı değerlerinin %114’ü kondenserde verimsiz çalışma koşullarında oluşmaktadır. Kondenserdeki hava girişlerinin kapatılması kondenser bölümündeki ekserji yıkımının 0,35 kW’dan 0,75 kW’a çıkmasına neden olmaktadır.

Evaluation of the Effects of Installation Faults in the Outdoor Unit of Air Conditioners Using Exergy Analysis

Öz

The increasing prevalence of global warming has led to a significant rise in the use of air conditioning systems, a trend widely acknowledged by numerous key institutions. However, this widespread adoption has brought about several challenges, particularly those stemming from improper installation practices. This study specifically examines the impact of installation faults in the condenser units of air conditioners on exergy destruction. One of the most critical issues identified is the blockage of the air inlet in the condenser unit, which often occurs due to installation errors. This study investigates the effects of such blockages on exergy destruction within the system. The findings indicate that installation faults in the condenser unit can substantially reduce the exergy efficiency of air conditioning systems, with efficiency values ranging from 38% to as low as 19%. Moreover, the exergy analysis of the condenser unit reveals that under inefficient operating conditions, exergy destruction increases by 114%. For example, when the air inlet of the condenser is obstructed, the exergy destruction in this section escalates from 0.35 kW to 0.75 kW, underscoring the critical impact of improper installation on system performance.
