Abstract

The refrigeration installation has separate refrigerator and freezer circuits each containing a compressor (C1/C2,C3/C4/C5/C with the pressure lines (8,16) leading from the latter combined before a condenser (V) and coupled via a selectively blocked def line (30) with the suction line (10) of the compressor (C3/C4/C5/C6) for the freezer circuit.
