Soğutma sistemlerinde kullanılan soğutucu akışkanların küresel ısınmada pay sahibi oldukları bilinmektedir. Bu nedenle küresel ısınmaya neden olmayan soğutucu akışkanların soğutma sistemlerinde kullanılması ve enerji performanslarının incelenmesi son yılların popüler konuları arasında yer almaktadır. Bu çalışmada, buhar sıkıştırmalı mekanik soğutma sisteminde R1234yf ve R134A soğutucu gazlarının -9°C, -6°C ve -3°C buharlaştırıcı ve 25°C, 30°C, 35°C yoğuşturucu sıcaklıklarında göstermiş oldukları termodinamik performans deneysel olarak incelenmiştir. Elde edilen sonuçlar R1234yf ve R134A gazlarının soğutma kapasitelerinin birbirine yakın olduğunu, kompresör güç tüketiminde ise R1234yf kullanılarak R134A’ya kıyasla ortalama %7,84 artış yaşandığını ortaya koymuştur. Sistemdeki en yüksek soğutma kapasitesinin R134A ile 1140 W, en fazla kompresör güç tüketiminin R1234yf ile 460 W, en büyük STK değerinin ise R134A ile 3,8 olduğu tespit edilmiştir.
