Refrigeration device comprising multiple storage chambers

Abstract

A refrigeration device has at least one first and second storage chambers and a refrigerant circuit in which a first throttle point, a first heat exchanger for controlling the temperature of the first storage chamber, a second throttle point, and a second heat exchanger for cooling the second storage chamber are connected in series. A high pressure line section upstream of the first throttle point and a low pressure line section downstream of the second heat exchanger form a first inner heat exchanger. A bypass line extends parallel to the high pressure line section to the first heat exchanger, and a control valve is provided in order to control the distribution of the refrigerant to the high pressure line section and the bypass line.
