Abstract

In internal combustion engine, car air conditioning system consumes large amount of energyabout 30% of the fuel in tropic areas. In this experiment, ANOVA (Analysis of Variance)manual method is used to reduce car AC energy consumption. People set their AC to operate attemperature 18°C, even though we can set indoor temperature in between 20°C to 24°Caccording to human comfort chart. In this experiment, AC efficiency is optimized by takingvarious readings at different rpm and different temperatures. Different methods are availableto enhance efficiency of car air conditioning. One of the methods is to set slightly higherindoor temperature as per human comfort chart. The study shows that increasing indoortemperature 20°C to 24°C save about 22% of compressor work and also increases thecoefficient of performance (COP).
