Abstract

The invention relates to a heat exchanger arrangement for heating of air, with a heat exchanger (8) which is integrated into a refrigerant circuit (60), configured to be able to have refrigerant flow through it and able to be impinged on by air. The heat is transferred from the refrigerant to the air. The heat exchanger (8) exhibits two components (8a, 8b) configured to be segregated from each other. The first component (8a) is configured with a condensation surface and a heat-removal surface. The second component (8b) exhibits a supercooling surface. Between the components (8a, 8b) on the refrigerant side, a refrigerant phase separation element is placed. The heat exchanger is configured as a tubular heat exchanger with tubes situated in rows, wherein the first component (8a) is configured with at least two rows and the second component (8b) with at least one row.
