Title
(EN) Refrigerating system

Abstract
(EN)
The invention relates to a refrigerating system. The refrigerating system comprises a multilevel compressor, a first refrigerating device, a second refrigerating device and a bypass mechanism, whereinthe multilevel compressor comprises at least two levels of compression parts which sequentially communicate, the first refrigerating device is provided with a first air inlet end and a first air discharge end, the first air inlet end is connected between two arbitrary levels of the compression parts in a communication mode, the first air inlet end communicates with an air outlet of the high levelcompression part in the two arbitrary levels of the compression parts, or an air outlet of the compression part of the level higher than that of the high level compression part in the two arbitrary levels of the compression parts, the second refrigerating device is provided with a second air inlet end and a second air discharge end, the second air inlet end communicates with an air outlet of thehighest level compression part, the second air discharge end communicates with an air return port of the lowest level compression part, the bypass mechanism is arranged between the first air dischargeend and the air return port of the lowest level compression part, and when the first refrigerating device works and the second refrigerating device stops running, the bypass mechanism is turned on. When the first refrigerating device works and the second refrigerating device stops running, the low levels of the compression parts in the multilevel compressor idle, a load provided by the compressoris matched with a load needed by the first refrigerating device, and resource waste is reduced.
