Abstract

Combined medium and low temperature refrigeration circuit for circulating a refrigerant in a predetermined flow direction includes, in flow direction, a heat-rejecting heat exchanger, a medium temperature refrigeration consumer, a medium pressure vapor separator having a vapor portion and a liquid portion connected to the medium temperature refrigeration consumer unit, a low temperature refrigeration consumer connected to the liquid portion of the medium pressure vapor separator, and a compressor unit having an inlet connected to the vapor portion of the medium pressure vapor separators and the low temperature refrigeration consumer.
