Development and analysis of a portable compressed liquid air cooling system for fast vehicle cabin cooling

Fast cooling of the cabin of parked vehicles under the sunshine has received considerable attention, especially when the vehicle cooling system does not have the capacity to perform such a task in a very short period of time. Most studies have focused on cooling the vehicle cabin throughout the parking period. In this paper, a novel portable cooling system is proposed to cool the vehicle cabin in 60 seconds. A three dimensional heat and mass transfer model is developed and used to evaluate the performance of the proposed cooling system. The proposed cooling system consists of an insulated container with a volume of 1.0 liter that is filled with compressed liquid air, which requires simple modification to the rear air vent system. The proposed system was able to lower the temperature of the vehicle by 12.0 degrees C and 15.2 degrees C for container pressures of 5.0 bar and 9.0 bar, respectively. (C) 2017 Elsevier Ltd and IIR.
