Single-circuit refrigerator

Abstract

A single-circuit refrigerator includes a refrigerant circuit in which the following are connected in series one after another between a pressure port and an intake port of a compressor: a condenser, a first throttle section, a first evaporator for cooling a first temperature zone of the single-circuit refrigerator, a second throttle section, a second evaporator for cooling a second temperature zone of the single circuit refrigerator, and an intake line. A downstream section of the intake line is connected with the first throttle section to form a first heat exchanger, and an upstream section of the intake line is connected with the second throttle section to form a second heat exchanger.
