摘要（英）：

The embodiment of the invention provides a working medium pressure self-adaptive low-temperature refrigerating system and a control method thereof, and relates to the refrigerating field. The working medium pressure self-adaptive low-temperature refrigerating system can solve the working medium high pressure problem during starting of the refrigerating system. The system comprises a compression refrigerating device, a middle heat regenerator, a first throttling unit and an evaporator unit, and further comprises a working medium expansion storage device, wherein a heat flow inlet of the middle heat regenerator communicates with a first outlet of the compression refrigerating device through a pipeline; a heat flow outlet of the middle heat regenerator is connected to an inlet of the evaporator unit through the first throttling unit; a first cold flow inlet of the middle heat regenerator communicates with an outlet of the evaporator unit through a pipeline; a cold flow outlet of the middle heat regenerator communicates with an inlet of the compression refrigerating device through a pipeline; and a second cold flow inlet of the middle heat regenerator communicates with a second outlet of the compression refrigerating device through a pipeline.
