Abstract

Current Vehicle Air Conditioning (VAC) systems, which are operated by compressors driven by Internal Combustion Engines (ICEs) or batteries, increase the fuel consumption and emissions depending on the thermal load of the vehicle passenger cabin. Since decreasing the thermal load of the vehicle will decrease the fuel consumption and emissions, studies in this area is very important from the economic and environmental aspects. In this study, an Auxiliary Air Conditioning (AAC) system for Internal Combustion Engine Vehicles (ICEVs) or Fuel Cell Vehicles (FCVs) that store Liquid Hydrogen (LH2) as a powering source has been proposed to make contribution to the works in this significant area. ICEVs were evaluated as Gasoline Equivalent Hydrogen Internal Combustion Engine Vehicles (GEHICEVs) and Diesel Equivalent Hydrogen Internal Combustion Engine Vehicles (DEHICEVs) considering their average fuel consumption rates according to the New European Driving Cycle (NEDC). According to the analyses, approximate hydrogen consumption values have been found that reach 0.7 g/s for GEHICEVs, 1.6 g/s for DEHICEVs, and 0.6 g/s for FCVs with maximum cooling rates of 326 W, 704 W, and 250 W, respectively.

Özet

İçten yanmalı motor veya batarya ile hareket ettirilen bir kompresör ile çalışan günümüz taşıt klimaları, taşıt yolcu kabininin ısıl yüküne bağlı olarak yakıt tüketimini ve emisyonları artırmaktadır. Kabin ısıl yükünün düşürülmesi yakıt tüketimi ve emisyonları azaltacağı için, bu alandaki çalışmalar ekonomik ve çevresel yönden çok önemlidir. Bu çalışmada, içten yanmalı motor veya yakıt hücresinde yakıt olarak sıvı hidrojen kullanan taşıtlar için yardımcı bir klima sistemi önerilmektedir. İçten yanmalı motoru olan taşıtlar, benzin (GEHICEV) ve dizele (DEHICEV) eşdeğer hidrojen yakıtlı taşıtlar olmak üzere ikiye ayrılmakta ve bu taşıtların yakıt tüketimleri Yeni Avrupa Sürüş Çevrimi’ne (NEDC) gore hesaplanmaktadır. Analizlere gore; GEHICEV, DEHICEV ve yakıt hücreli taşıtlarda (FCV) yaklaşık hidrojen tüketim değerlerinin sırasıyla 0.7-1.6- 0.6 g/s olduğu, ve değerlere gore yapılabilecek en yüksek soğutma değerlerinin yine sırasıyla 326-704-250 W olarak ortaya çıktığı bulunmuştur.
