Using a car platform as the subject,the causes of freezing on the air conditioning evaporator surface are analyzed.The location of the temperature sensor,the temperature value of sensor feedback to the controller and the reading accuracy of the con-troller are the main factors that influence freezing.Accordingly a program for the improvement of the evaporator temperature sensor's R/T curve is proposed.Through automotive environment simulation and real-vehicle road testing,the results show that the im-proved measures can effectively prevent the evaporator surface from freezing.The comfort of interior environment and the reliability of the air conditioning system are improved.
