Solutions for Reducing the Energy Consumed by the Automotive HVAC System

The first cars with air conditioning appeared in the early 1940s. Then, 1500 Packard cars received an air conditioning system developed by Nash. In the 60s about 20% of the total production of cars had air conditioning system. Nowadays car manufacturers consider air conditioning as a standard option and try various solutions to increase thermal comfort and road safety. The air conditioning system in the current configurations is a big energy consumer system. All changes made to reduce the energy consumed will take into account temperature, humidity level, vibration and noise so that human safety and comfort are not affected. The purpose of this paper is to review the ways to reduce the energy consumed by the air conditioning system of cars and their importance.
