Abstract: A reversible heat pump has a first refrigeration circuit (2) flown through by carbon dioxide, a first hydraulic circuit (21) to feed a source liquid through an evaporator device (4) of the first refrigeration circuit (2) and to cause the evaporation of the carbon dioxide, a second refrigeration circuit (15) flown through by a refrigerating fluid, and a second hydraulic circuit (27) to heat a utility liquid feeding it in succession and in order first through a cooling device (6) of the first refrigeration circuit (2) and, thus, through a condenser device (18) of the second refrigeration circuit (15).
