1. A reversible heat pump device (100) by means of appropriate direction of air flows, with R744 refrigerant for producing hot and cold air, including:
a system of intake dampers (1) consisting of concentric cylinders (A, B, C), equipped with suitable openings and designed to implement a reversibility between a heating operation and a cooling operation;
a refrigeration circuit comprising a cold exchanger (2) and a hot exchanger (3) located between the system of intake dampers (1) and a delivery damper system (4);
the delivery damper system (4) consisting of concentric cylinders (D, E, F) equipped with suitable openings and designed to implement the reversibility between the heating operation and the cooling operation in a manner consistent with the system of intake dampers (1).
