Abstract:
A refrigerator-freezer of the combined type (3) comprises a first (2) and a second (4) refrigerating units and a single cooling circuit (7) for both units, which are fluid-dynamically and reciprocally connected by an air passage conduit (25); the temperature inside the first unit (2) is controlled by a device (1) comprising motorised interception means (27) of the passage conduit; electronic control means (30) of the motorised interception means, directly carried aboard a supporting body (26) adapted in use to be arranged along the passage conduit (25); an electronic temperature sensor (31) operatively and directly connected to the electronic control means (30), carried aboard the supporting body; and ventilator means (40), carried aboard the supporting body, operated by the electronic control means (30) of the motorised interception means for selectively ensuring circulation of air by forced convection between the first and second refrigerating units (2, 4) along the passage conduit.
Abstract:
A method and device for controlling the inside temperature of a refrigeration compartment, wherein control means are controlled by a thermostat; a temperature sensor is located far away from the refrigerating means and in a specific portion of the inside volume of the refrigeration compartment, e.g. on a lighting fixture; and the specific portion of the inside volume of the refrigeration compartment is selected with the exclusion of a first top portion of the volume of the refrigeration compartment having a volume equal to 8-10% of the total inside volume of the refrigeration compartment, with the exclusion of a second front portion of a depth equal to at least 10% of the total inside depth of the refrigeration compartment, and preferably also with the exclusion of a bottom portion of the refrigeration compartment.
