Characteristic Evaluation on the Cooling Performance of an Electrical Air Conditioning System Using R744 for a Fuel Cell Electric Vehicle

The objective of this study was to investigate the cooling performance characteristics of an electrical air conditioning system using R744 as an alternative of R-134a for a fuel cell electric vehicle. In order to analyze the cooling performance characteristics of the air conditioning system using R744 for a fuel cell electric vehicle, an electrical air conditioning system using R744 was develop...

Optimization of Vehicle Air Conditioning Systems Using Transient Air Conditioning Performance Analysis

The National Renewable Energy Laboratory (NREL) has developed a transient air conditioning (A/C) system model using SINDA/FLUINT analysis software. It captures all the relevant physics of transient A/C system performance, including two-phase flow effects in the evaporator and condenser, system mass effects, air side heat transfer on the condenser/evaporator, vehicle speed effects, temperature-d...

Mathematical Model of Electric Vehicle Power Consumption for Traveling and Air-Conditioning

In order to make maximum use of the EV (electric vehicle) battery, evaluating the remaining battery capacity and the power consumption is important. Evaluation method of the remaining battery capacity with accuracy has been proposed. Moreover, the evaluation method of the power consumption for traveling has been proposed. However, the power consumption for vehicle-mounted air-conditioner is 30%...

Development of a Novel Structure Rotary Compressor for Separate Sensible and Latent Cooling Air-Conditioning System

The energy efficiency of separate sensible and latent cooling (SSLC) airconditioning system is higher than traditional one, since SSLC system uses separate cycles which can raise the evaporating temperature of sensible cycle. Separate cycles often include two separate compressors, which makes the initial investment of SSLC cycle too expensive to use in room air conditioning. A novel structure r...
