Title: METHOD FOR CONTROLLING A OZONIZER
Abstract:
A method is described for controlling an ozoniser group installed in a commercial open-type refrigerator bench for conserving, displaying and selling fresh food. The refrigerator bench comprises a refrigerated volume at least partially open, a refrigerating machine controlled by a temperature sensor and one or more fans configured for delivering the cold produced by the refrigerating machine into the refrigerated volume, through an air current. The ozoniser group comprises a control unit connected to a sensor for measuring the ozone concentration on one side and to an ozone generator on another side. The ozone generator is controlled as a function of an algorithm for estimating the relative humidity inside the refrigerator bench, so that when the estimated relative humidity value is below a threshold humidity value, the ozone generator is controlled as a function of the values measured by the sensor; when the estimated relative humidity value is above the threshold humidity value, the ozone generator is controlled with independent control logics excluding the values measured by the sensor, and when the refrigerator bench is cleaned, a first sub-step is carried out for checking the ozone generator as a function of the ozone concentration value measured by the sensor, and a subsequent second sub-step in which the ozone generator is controlled independently of the ozone concentration value measured by the sensor.
