Reversible device for the production of hot and cold air

Abstract

A reversible heat pump device (100) is described by means of an appropriate direction of air flows, with R744 refrigerant (natural gas, non-toxic, non-flammable, readily available), for the production of hot and cold air; the device object of the present invention is composed of a suction damper system (1) consisting of concentric cylinders (A, B, C), designed to implement the reversibility of the operation between heating and cooling), and a refrigeration circuit comprising: cold exchanger (2) and a hot exchanger (3), located between the intake damper system (1) and the delivery damper system (4) consisting of concentric cylinders (D, E, F), also designed to implement the reversibility of operation in a manner consistent with the system of intake dampers (1).
