An operating method and refrigeration circuit (1), in particular for a heat pump (2) with cycle inversion; wherein the refrigeration circuit (1) has a finned heat exchanger (5), which is adapted to be installed on the outside of a room (H) to be conditioned, and a utility (7), adapted to be installed on the inside of the room (H) to be conditioned; wherein the exchanger (5) is adapted to be flowed through, on the outside, by an air flow in a given direction (W) and, on the inside, by a refrigerant fluid (F), which can selectively flow either in a first direction (R1) or in a second direction (R2); wherein the exchanger (5) is flowed through by the fluid (F) always in a countercurrent flow relative to the direction (W) of the outside air whatever the feeding direction (R1; R2) of the refrigerant fluid (F) on the inside of the refrigeration circuit (1) is. |
