Counter with air conditioning and freezing system

A counter with air conditioning and freezing system comprising a self-supporting structure (C) with:

• an insulated housing in which at least one support for trays (A, B) is located;
• an air conditioning and freezing element which allows the temperature of an air current circulating through the self-supporting structure (C) to be modified;
• and the counter comprises:
• an insulated interior air conditioning and freezing system (R) arranged on the self-supporting structure (C) configured to direct an air current through the interior of the self-supporting structure (C) and comprising:
• a frontal return opening (R1) arranged in an upper frontal section of the support structure (C);
• an insulated frontal vertical return (R2) through which the air current, entering through the frontal return opening (R1), passes;
• a horizontal air passage (R4) connected to the insulated frontal vertical return (R2) and which is arranged below the housing;
• an insulated rear vertical return (R7) through which the air, arriving from the horizontal air passage (R4), passes;
• an insulated exterior air conditioning and freezing system (D) which extends from a rear section of the self-supporting structure (C) and which is configured to create an air curtain and comprises:
• at least one thermally insulated column (D1) which extends from the self-supporting structure (C) and which is hollow and is connected to the insulated rear vertical return (R7) to allow the passage of the air from said insulated rear vertical return (R7);
• a thermally insulated horizontal conduit (D2) connected to the at least one thermally insulated column (D1) for the passage of the air from said thermally insulated column (D1);
• a longitudinal groove (D3) which extends through the thermally insulated horizontal conduit (D2) through which it exits;
• an exterior plate (D4) arranged in correspondence with the longitudinal groove (D3) oriented at an inclination such that it controls the exit direction of the air which passes through the longitudinal groove (D3) and directs it towards the frontal return opening (R1), creating the air curtain.
