Abstract
A refrigeration device has a first storage chamber, a second storage chamber and a refrigerant circuit, in which a first controllable throttle point, a first heat exchanger for controlling the temperature of the first storage chamber, a second controllable throttle point and a second heat exchanger for cooling the second storage chamber are connected in series between a pressure connection and a suction connection. A hot line section, located upstream of the second heat exchanger, and a cold line section, located downstream of the second heat exchanger, are routed in thermal contact with respect to one another in order to form an internal heat exchanger. The first heat exchanger is connected to the pressure connection bypassing the hot line section.
