The present disclosure relates to a compact heat exchanger unit (1) within an air conditioning apparatus for a vehicle for the condensation of refrigerant cooled with liquid, wherein a condenser region (6) for the condensation of the refrigerant formed as a heat exchanging surface, a separate excess cooling region (4) for the sub-cooling of the refrigerant and an internal heat exchanger region (3) are combined as plate packets in a plate heat exchanger and that a separate high-pressure refrigerant collector (15) is placed downstream of the condenser region (6) and integrated as refrigerant collector in the air conditioning module, wherein the condenser region (6) and the excess cooling region (4) are arranged side by side as plate packets of a plate heat exchanger, wherein the refrigerant after flowing through the condenser region (6) is guided and collected into the separate high-pressure refrigerant collector (15), then it is guided into the excess cooling region (4) and the internal heat exchanger region (3) and subsequently via an expansion engine (9) into an evaporator region (2) and wherein the plates of the condenser region (6) and of the excess cooling region (4) are formed in Chevron design.
