A simulation for predicting potential cooling effect on LPG-fuelled vehicles
Liquefied Petroleum Gas vehicles (LPG Vehicles) provide a potential cooling effect about
430 kJ/kg LPG consumption. This cooling effect is obtained from the LPG phase change
from liquid to vapor in the vaporizer. In the existing system, energy to evaporate LPG is
obtained from the coolant which is circulated around the vaporizer. One advantage is that
the LPG (70/30 propane/butane) when expanded from 8 bar to at 1.2 bar, the temperature is
less than-25 C. These conditions provide opportunities to evaporate LPG with ambient air …
