Summary

The paper reports a new method of refrigerant flow control in a full-scale commercial container refrigeration system. Fuzzy logic control is applied to the control of superheat using an electronic expansion valve. A comparison between the conventional proportional-integral and derivative controls of the superheat was made with fuzzy control. It was shown that the fuzzy controller performed better in terms of smaller overshoot of the superheat and faster settling time of the superheat response during the pulldown of evaporator load and compressor cycling mode for capacity control.
