A review study on LPG as an alternative refrigerant

Öz

This study reviews the literature, which has numerous works on the use of LPG, a hydrocarbon fuel utilized in many types of equipment, as an alternative refrigerant without any change in refrigerators, air conditioners, and similar cooling devices at various sizes. Referring to the results obtained from these studies LPG provides improvement of COP, reduction of the refrigerant amount used and energy saving compared to the other refrigerants in cooling devices draw attention of scientists. Outlining the results of the works given in this study, COP improvement, refrigerant reduction by mass, and energy saving reach to the values of 25.1%, 50%, and 90%, respectively, in case of using LPG instead of convensional refrigerants in different types of cooling machines.

ALTERNATİF BİR SOĞUTUCU GAZ OLARAK LPG ÜZERİNE BİR DERLEME ÇALIŞMASI

Öz

Bu çalışma, çeşitli boyutlardaki buzdolabı, klima ve benzeri soğutma gereçleri olmak üzere pek çok ekipmanda alternatif bir soğutucu gaz olarak kullanılan bir hidrokarbon yakıt olan LPG üzerine yapılan çok sayıda çalışmaları içeren literatürü derlemektedir. Bu çalışmalardan elde edilen sonuçlara başvurulduğunda LPG'nin diğer soğutucularla kıyaslandığında soğutma gereçlerinde COP'yi geliştirdiği, kullanılan soğutucu gaz miktarını düşürdüğü ve enerji tasarrufu sağladığı bilim adamlarının dikkatini çekmektedir. Bu çalışmada verilen eserlerden elde edilen sonuçlar özetlendiğinde, farklı tiplerde soğutma makinelerinde geleneksel soğutucu gazlar yerine LPG kullanılması durumunda COP gelişimi, kütlesel olarak soğutucu gaz miktarındaki azalma ve enerji tasarrufu sırasıyla %25,1, %50 ve %90 değerlerine ulaşmaktadır.
