Abstract

A reheating method for operating a refrigeration system for a motor vehicle is described, the refrigeration system includes a refrigerant compressor, which is connectable or connected to a primary line and a secondary line; an outer heat exchanger, which is arranged in the primary line; an evaporator, which is arranged in the primary line; a heating register, which is arranged in the secondary line; at least one movable temperature flap which is arranged upstream or downstream of the heating register in relation to a supply air flow direction; and at least one shut-off element, which is arranged downstream of the heating register in the secondary line. The reheating method includes adjusting the at least one shut-off element into a position in which refrigerant flows downstream of the heating register into the evaporator, while bypassing the external heat exchanger.
