Abstract
The global warming danger requires new technologies to minimize depletion ozone layer. The ozone layer protects earth from various harmful radiations to enter on earth. In Mobile Air Conditioning (MAC) systems the major contributing factor of ozone depletion is refrigerant. The rate of increase of number of automobiles is tremendous every year which cumulatively increase ozone depletion. To improve the Mobile Air Conditioning system performance and reduce the effect on environment, R134 refrigerant with addition of internal heat exchanger and thermal expansion valve can be experimented .Internal heat exchanger is in the form of micro channel tube with heat transfer enhancement characteristics. Moderate and severe Conditions show improvement of 10-12% increase in cooling capacity performance as compared to baseline condition.
