Provided is a novel ultralow-temperature compression refrigerating system. A primary-throttling intermediate-incomplete-cooling one-machine double-stage compression refrigerating system is composed of a one-machine double-stage compressor, a first oil separator, a second oil separator, a mechanical filter, a marine condenser, an intermediate cooler, a first throttling device, a second throttling device, a drying cooler, an evaporator and a gas-liquid separator, and a single-stage compressor is arranged between the one-machine double-stage compressor and the evaporator in series. The novel ultralow-temperature compression refrigerating system mainly solves the problems that the marine one-machine double-stage compression refrigerating system has an overlarge compression ratio under an ultralow-temperature refrigeration working condition, and the double-stage compressor is in a full-load operation condition or even an overload operation condition for a long period. According to the technical scheme, the single-stage compressor is arranged between the one-machine double-stage compressor and the evaporator in series, so the compression ratio when the one-machine double-stage compressor works to achieve ultralow temperature is reduced, and the use efficiency of the compressors is improved; in addition, the system saves more energy in the operation process.
