Abstract

In internal combustion engine, car air conditioning system consumes large amount of energy
about 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 at
temperature 18°C, even though we can set indoor temperature in between 20°C to 24°C
according to human comfort chart. In this experiment, AC efficiency is optimized by taking
various readings at different rpm and different temperatures. Different methods are available
to enhance efficiency of car air conditioning. One of the methods is to set slightly higher
indoor temperature as per human comfort chart. The study shows that increasing indoor
temperature 20°C to 24°C save about 22% of compressor work and also increases the
coefficient of performance (COP).
