AIR CONDITIONING AND SELECTED VEHICLE CHARACTERISTICS

The main purpose of the paper is to determine the change in vehicle energy efficiency due to using the air conditioning system. There is a connection between the changes in vehicle energy efficiency and fuel consumption together with time needed for vehicle acceleration. The paper comprises the measurement results performed at stabilized speeds as well as during vehicle acceleration. The final part of the paper outlines the result of calculation of change in vehicle energy efficiency resulting from air conditioning unit used during New European Driving Cycle.
