Abstract
A reheating method for operating a refrigeration system for a motor vehicle. The refrigeration system includes a refrigerant compressor, connected to a primary line and a secondary line; an external heat exchanger; an evaporator; a heating register; at least one movable temperature flap; and at least one shutoff element, which is arranged downstream of the heating register in the secondary line. The reheating method includes following steps: setting the at least one shutoff element in a position in which the refrigerant flows into the evaporator downstream of the heating register while bypassing the external heat exchanger, and incorporating at least one further heat sink, which is fluidically arranged in parallel or in series to the evaporator, in particular a chiller operating as a water heat pump evaporator and/or the external heat exchanger operating as an air heat pump evaporator.
