“…As of vehicles constantly takes different values according to the weather conditions, size of the vehicles, and number of the occupants, 1000 W, 2000 W, 3000 W, 4000 W, 5000 W, and 6000 W values were chosen for the determination of the AC savings at different conditions. These values are compatible with the works of Meier et al [82] and Fayazbakhsh and Bahrami [96] also.…”

“…Today's commercially available FCVs like Toyota Mirai, Honda Clarity Fuel Cell, Hyundai Nexo etc. have an average hydrogen consumption, which is calculated using the hydrogen tank capacity and total range in NEDC with full capacity of the tank, of 1 kg/100 km is also compatible with the literature [82]. Therefore, values between 0 and 6 kg/100 km are suitable for a great variety of vehicles in a wide range of driving conditions.…”

“…In addition, apart from the application of the VAAC system for the vehicle interior cabin, especially for FCVs, a further possible integration concept of the system is the cooling of the vehicle components such as the power electronics, the battery or the electric motor, which, for an overall propulsion efficiency of 80%, between 0.75-2.5 kW of waste heat of an FCV is produced from these components [82].…”

“…A similar flow is encountered in state of the art fuel cell vehicles. Differently in fuel cell vehicles hydrogen is used to generate electricity [82]. The fuel cell vehicles are electric vehicles that utilize hydrogen in fuel cell units to generate electricity onboard of the vehicle, eliminating the need for heavy batteries and long periods of recharging times.…”

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 (LH 2) 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.
