Abstract

The refrigeration plant is designed so that the compressor is arranged for the upper temperature level in a first conducting circuit (LK1). The compressor (3) for the lower temperature level is arranged in a second conducting circuit (LK2). A valve (4) is arranged on the suction side between the first and second conducting circuit, which in event of a fault, opens the suction line (5) to the first conducting circuit. In addition, there is a non-return valve (7) between at least one compressor (2) of the first circuit lying next to the second conducting circuit on the suction side (6). The parallel working compressors (1,2) of the first conducting circuit are connected with the one or more compressors of the second conducting circuit together to a pressure line (8).
