DEVELOPMENT OF FUZZY LOGIC CONTROL FOR VEHICLE AIR CONDITIONING SYSTEM
Abstract: A vehicle air
conditioning system is experimentally investigated. Measurements were taken
during the experimental period at a time interval of one minute for a set point
temperature of 22, 23 and 24oC with internal heat loads of 0, 1 and 2 kW. The
cabin temperature and the speed of the compressor were varied and the
performance of the system, energy consumption and energy saving ware analyzed.
The main objective of the experimental work is to evaluate the energy saving
obtained when the fuzzy logic control (FLC) algorithm, through an inverter,
continuously regulates the compressor speed. It demonstrates better control of
the compressor operation in terms of energy consumption as compared to the
control by using a thermostat imposing On/Off cycles on the compressor at the
nominal frequency of 50 Hz. The experimental set-up consists of original
components from the air conditioning system of a compact passenger vehicle. The
experimental results indicate that the proposed technique can save energy and
improve indoor comfort significantly for vehicle air conditioning systems
compared to the conventional (On/Off) control technique.
