Resumo: An experimental study of a resistive sensor is developed. Its performance is evaluated in function of the temperature and relative humidity of air, the temperature of the refrigerant and the relative position of the sensor on the evaporator’s surface. A resistive sensor that include two electrodes measures the electrical resistance of the medium. The experimental study was developed in an experimental facility where different air and refrigerant conditions were set up. The results of the experimental study allowed analyzing the propagation of the frost layer and determining the existence of ice on the evaporator’s surface. The results agreement is satisfactory for water detection and high for the detection of the frost layer. The ice behavioral characteristics plays a key role in frost detection using resistive sensors.
