摘要： Display cabinet for refrigerated products comprising a support structure (2) which internally delimits a refrigeration chamber (21) extended between a first access side (21') and an opposite second access side (21") at which it is provided, respectively, with at least one first access opening (A) and with at least one second access opening (B).
The support structure (2) also delimits at least one first technical compartment (22), placed above said refrigeration chamber (21) and air connected to the latter by means of at least two delivery mouths (211), placed at separate access sides (21) in order to introduce a corresponding delivery air flow (Fm) towards said refrigeration chamber (21), and by means of at least one recovery mouth (212), in order to pick up a recovery air flow (Fr) coming from said refrigeration chamber (21). The display cabinet (1) also comprises a first series of display shelves (31), and a second series of display shelves (32), which are spaced from each other and between them delimiting a central suction channel (30), air connected to the recovery mouth (212). The display cabinet (1) also comprises ventilation means (4) and cooling means (5), placed within the first technical compartment (22) in order to intercept, cool and force the recovery air flow (Fr) recovered by the recovery mouth (212). The shelves of each series of shelves (31, 32) are vertically spaced and between them define conveyance openings (300) air connected to the central suction channel (30) in order to flow at least part of the delivery air flows (Fm) coming from the delivery mouths (211) towards the central suction channel (30).-

摘要： Refrigerated display cabinet for refrigerated products, comprising a support structure (2), comprising a refrigerated chamber (21) and a support frame (3), substantially contained within the refrigerated chamber (21) and comprising at least one dividing wall (30), which divides said refrigerated chamber (21) into a first half-chamber (S1) and into a second half-chamber (S2).
The display cabinet also comprises an air recirculation circuit (4), passing between the first half-chamber (S1) and the second half-chamber (S2), ventilation means (5), operatively connected to the air recirculation circuit (4), and a thermal cooling unit (6), placed to intercept the air recirculation circuit (4) in order to cool the air.
The air recirculation circuit (4) comprises a first air conveyance channel (40), placed below the refrigerated chamber (21) and placed as an air connection between the first half-chamber (S1) and the second half-chamber (S2) and a second conveyance channel (41), placed above said refrigerated chamber (21) and placed as an air connection between the first half-chamber (S1) and the second half-chamber (S2). The thermal cooling unit (6) comprises only one evaporator placed to intercept one between the first conveyance channel (40) and the second conveyance channel (41).-

摘要： Display cabinet for preserving food products, comprising a support structure (2), defining a containment volume (V) for housing the food products and provided with at least one access opening (A) for accessing the containment volume (V) and at least two uprights (20), which are extended along a main extension direction (Y) and laterally delimit the at least one access opening (A).
In addition, the display cabinet comprises a plurality of shelves (3), which are intended to receive the food products in abutment within the containment volume (V) and comprising at least two brackets (31), each of which mechanically fixed to at least one corresponding upright (20) and extended projectingly from the upright (20), and at least one ledge (32) mechanically connected to the brackets (31) and intended to receive the food products in abutment. The shelves (3) are mechanically supported by the uprights (20) and are cantilevered extended from the uprights (20) towards the interior of the containment volume (V), and each bracket (31) is extended along a depth direction (Z) between a first end (31'), placed in proximity to the access opening (A) and fixed to a corresponding upright (20) and a second end (31") that is free, opposite the first end (31') and placed within the containment volume (V). Each ledge (32) is extended depth-wise from a front edge (320) which is placed distal with respect to the front opening (A) in order to define, with the uprights (20), a passage opening (B) inside the containment volume (V) for air recirculation within the display cabinet.-

摘要： Method for controlling a refrigerator system comprising a first and a second refrigerated display and a logic control unit, and such method provides for the execution of a first step of cooling the first refrigerated display and a control step.
In the control step, the logic control unit calculates a first virtual time (tv1), in which the first internal temperature (Ti1) of the first refrigerated display reaches a first objective temperature (Tobb1), calculates a second virtual time (tv2), in which the second internal temperature (Ti2) of the second refrigerated display reaches the second maximum threshold temperature (Tmax2), calculates the time interval (Δt) that lies between the first virtual time (tv1) and the second virtual time (tv2) and sets a first real time (tr1), at which the first step of cooling the first refrigerated display terminates, and a second real time (tr2), at which a second step of cooling the second refrigerated display starts.
The first real time (tr1) is subsequent to the second real time (tr2) in order to at least partially overlap the first cooling step and the second cooling step.-

摘要： Refrigerator system (1) which comprises at least one refrigeration station (2), provided with at least one compressor (21), a plurality of refrigerated displays (3), and each of which comprises at least one evaporator (31) and a refrigerated chamber (32), susceptible of containing products to be preserved. The refrigerator system (1) also comprises a refrigeration circuit (4), selectively placed to connect between the compressor (21) and the evaporators (31), at least one logic control unit (5), connected to the compressor (21) in order to cool a corresponding refrigerated display (3) for a predetermined cooling time period. The refrigerator system (1) also comprises two or more sensors (6), configured for detecting corresponding operative parameters and sending a plurality of signals to the logic control unit (5) corresponding to the operative parameters, and such sensors (6) are selected from among: a contact sensor (61), a temperature sensor (62), a pressure sensor (63), a movement sensor (64), a volumetric sensor (65), a thermal camera (66), a people-counted sensor (67).
The logic control unit (5) is placed in communication with the plurality of sensors (6) in order to receive the signals from the sensors (6) and comprises at least one calculation unit (51), configured for calculating, on the basis of the aforesaid signals, an additional time beyond the cooling time.
