Abstract:
A produce storage chamber comprising a chamber capable of encasing produce, a refrigeration system, at least one ozone generation units, and at least one ethylene scrubbers. The chamber is capable of delaying postharvest produce deterioration using at least one of temperature control, ozone generation, and ethylene scrubbing.

ABSTRACT The present invention includes an inner electrode 6 formed inside a dielectric body 4 and a surface electrode 5 formed on a surface of the dielectric body 4, and the surface electrode 5 is formed in a grid pattern with acuminate parts 5a formed inside the grid squares. More specifically, each acuminate part 5a is made of a triangle whose vertices are two arbitrary points on a side of the grid square and an arbitrary point inside the grid square, or a quadrangle whose vertices are a crossing of grid lines, an arbitrary point near a straight line connecting crossings of grid lines in the diagonal positions, and two arbitrary points on sides of the grid square. The present invention provides an ion generating element capable of generating positive ions and negative ions in a stable manner even under a wide range of applied voltage while curbing the increase in noise, and capable of decreasing the generation of ozone, and provides an ion generator, air conditioning apparatus, cleaner and refrigerator using this ion generating element.
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.
